A. 1 gallon white,1 gallon maroon
B. 1 gallon white,2 gallons maroon
C. 2 gallon white,2 gallons maroon
D. 2 gallon white,3 gallons maroon ​

Answers

Answer 1

To determine how many gallons of white and maroon paint Frank will need, we need to calculate the total square footage for each color. Here's a step-by-step explanation:

1. Determine the square footage of the floor and ceiling that will be painted white. Since they are the same size, we can calculate the area of one and multiply it by 2.
2. Determine the square footage of all the walls that will be painted maroon. Calculate the area of each wall and sum them up.
3. Determine the square footage of the door that will be painted white. Subtract this value from the total maroon wall area.
4. Divide the total square footage of the white and maroon surfaces by 400 sq ft (coverage of one gallon) to find out how many gallons are needed for each color.

After calculating the areas and the number of gallons needed, compare the results with the given options (A, B, C, or D). Keep in mind that we don't have the specific dimensions for Frank's room, but following these steps will help you solve the problem once you have the necessary measurements.

An isosceles triangle has legs measuring 9 feet and a base of 12 feet. Find the measure of the base angle, x, to the nearest degree

Answers

The measure of the base angle x is approximately 81.54 degrees.

To get the measure of the base angle, we can use the fact that the sum of the angles in a triangle is always 180 degrees. Since this is an isosceles triangle, we know that the two base angles are congruent (they have the same measure).
Let's call the measure of each base angle y. Then we can set up an equation:
y + y + x = 180
Simplifying, we get:
2y + x = 180
Now we can use the fact that the legs of the triangle are congruent to find the measure of y. Since this is an isosceles triangle, we know that the two legs are congruent. This means we can use the Pythagorean theorem to find the length of the height, h, of the triangle:  h^2 = 9^2 - (12/2)^2
h^2 = 81 - 36
h^2 = 45
h = sqrt(45)
h = 6.71 (rounded to two decimal places)
Now we can use the definition of the tangent function to find y:
tan(y) = h / (12/2)
tan(y) = 6.71 / 6
tan(y) = 1.1183                                                                                                                                                                                     y = tan^-1(1.1183)
y = 49.23 degrees (rounded to two decimal places)
Finally, we can substitute this value of y into our equation to find x:
2y + x = 180
2(49.23) + x = 180
98.46 + x = 180
x = 81.54 degrees (rounded to two decimal places)
Therefore, the measure of the base angle x is approximately 81.54 degrees.

Cam put 4 12/25 pounds of rice in bags that each weigh 7/25 pound. She uses 1/8 of the bags of rice. How many bags of rice are left?


Answers

Answer:

14

Step-by-step explanation:

Cam put a total of 4 12/25 pounds of rice in bags, which is equivalent to 112/25 pounds of rice.

Each bag weighs 7/25 pound, so the total number of bags of rice is:

(112/25) ÷ (7/25) = 16

Cam uses 1/8 of the bags of rice, which is:

(1/8) x 16 = 2

So Cam uses 2 bags of rice.

The number of bags of rice left is the total number of bags (16) minus the number of bags used (2):

16 - 2 = 14

Therefore, 14 bags of rice are left.

D. 35,400



PLS DON'T PUT LINKS AND WRITE ANSWER, THX! I WILL MARK BRAINLIEST IF YOU WRITE THE ANSWER!

Answers

The answer is option C) 30,700

Why the answer is option C?

The problem involves using linear interpolation to estimate the population of Little Elm in 2020 based on the given data from 2010 and 2015.

To start, we need to calculate the annual growth rate of the population between 2010 and 2015. This can be done by taking the difference between the population in 2015 and the population in 2010, and then dividing that difference by the number of years in that time period:

Annual growth rate = (17,150 - 3,646) / 5 = 2,700

This means that, on average, the population of Little Elm grew by 2,700 people per year between 2010 and 2015.

Next, we can use this annual growth rate to estimate the population of Little Elm in 2020. To do this, we need to add 10 years of growth to the initial population of 3,646 (since we want to estimate the population in 2020, which is 10 years after 2010):

Estimated population in 2020 = 3,646 + (2,700 x 10) = 30,646

Therefore, the estimated population of Little Elm in 2020 is approximately 30,700, which corresponds to answer choice C.

3. Un negociante tiene un capital de 40 000 soles y piensa guardarlo por un periodo de 2 años. Tiene dos propuestas de bancos. Banco A: 1,5 % bimestral. Banco B: 0,5% mensual. ¿Cuál de las dos propuestas le conviene?, ¿Cuánto interés recibirá en la entidad más conveniente? (7 puntos) Alternativas

Answers

Answer:

Para comparar las propuestas de los bancos, debemos llevar las tasas de interés a una misma unidad de tiempo. Podemos convertir la tasa del Banco A de bimestral a mensual multiplicándola por 2 (ya que hay 6 bimestres en 1 año):

Tasa del Banco A: 1,5% * 2 = 3% mensual

Tasa del Banco B: 0,5% mensual

Para calcular los intereses que se obtendrán en cada banco, podemos utilizar la fórmula del interés compuesto:

I = C * ((1 + r/n)^(n*t) - 1)

Donde:

I es el interés

C es el capital inicial

r es la tasa de interés en forma decimal

n es el número de veces que se capitaliza al año

t es el tiempo en años

Para el Banco A, como la tasa está en meses, capitalizaremos mensualmente (n=12):

I = 40 000 * ((1 + 0,03/12)^(12*2) - 1) = 4 896,18 soles

Para el Banco B, como la tasa ya está en meses, capitalizaremos mensualmente (n=12):

I = 40 000 * ((1 + 0,005)^(12*2) - 1) = 4 225,48 soles

Por lo tanto, la propuesta más conveniente es la del Banco A, ya que ofrece una tasa de interés mayor y genera un interés total de 4 896,18 soles. En cambio, el Banco B genera un interés total de 4 225,48 soles.

A chicken and a roaster, on the same straight line, are heading towards the chicken coop which is halfway between them. The chicken is at A(-2,4) and the roasted is at B(4,-4)


Please answer a & b with an explanation :)

Answers

The x-coordinate of the chicken coop is 1, which means that the chicken coop is located at the point (1, 0).

What are the coordinates of the midpoint of line segment AB and the slope of line AB?

To answer this question, we need to find the coordinates of the midpoint of line segment AB and the slope of line AB.

a) To find the midpoint of line segment AB, we use the midpoint formula:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

where (x1, y1) and (x2, y2) are the coordinates of the endpoints of the line segment.

Substituting the values, we get:

Midpoint = ((-2 + 4)/2, (4 - 4)/2)

Midpoint = (1, 0)

Therefore, the midpoint of line segment AB is (1, 0).

b) To find the slope of line AB, we use the slope formula:

Slope = (y2 - y1)/(x2 - x1)

Substituting the values, we get:

Slope = (-4 - 4)/(4 - (-2))

Slope = (-8)/(6)

Slope = -4/3

Therefore, the slope of line AB is -4/3.

Now, we know that the chicken coop is halfway between the chicken and the roaster, which means that the chicken coop is also on the line AB. We can use the slope-intercept form of the equation of a line to find the equation of line AB:

y = mx + b

where m is the slope of the line, and b is the y-intercept.

Substituting the values of slope and midpoint, we get:

y = (-4/3)x + (4/3)

Therefore, the equation of line AB is y = (-4/3)x + (4/3).

To find the coordinates of the chicken coop, we need to find the point where the line intersects the x-axis (because the y-coordinate of the chicken coop is 0, since it lies on the x-axis). To do this, we set y = 0 in the equation of line AB:

0 = (-4/3)x + (4/3)

4/3 = (4/3)x

x = 1

Therefore, the x-coordinate of the chicken coop is 1, which means that the chicken coop is located at the point (1, 0).

The distance between the chicken  at A(-2,4) and the roasted is at B(4,-4).

How chicken  and roasted of points?

To determine the chicken of the line that contains points A(-2,4) and B(4,-4), we can use the slope formula:

slope = (y2 - y1) / (x2 - x1)

Substituting the coordinates, we get:

slope = (-4 - 4) / (4 - (-2)) = -8 / 6 = -4 / 3

So the slope of the line is -4/3.

To find the equation of the line, we can use the point-slope form:

y - y1 = m(x - x1)

Substituting one of the points and the slope, we get:

y - 4 = (-4/3)(x - (-2))

Simplifying, we get:

y = (-4/3)x + 4/3

Therefore, the equation of the line that contains points A(-2,4) and B(4,-4) is y = (-4/3)x + 4/3.

To find the distance between the chicken and the roaster, we can use the distance formula:

d = sqrt[(x2 - x1)^2 + (y2 - y1)^2]

Substituting the coordinates, we get:

d = sqrt[(4 - (-2))^2 + (-4 - 4)^2] = sqrt[6^2 + (-8)^2] = sqrt[100] = 10

Therefore, the distance between the chicken and the roaster is 10 units.

Answer:

Problem 8:
Option C)       DE = √21

Problem 9:
Option C)     Perimeter = 30 cm

Step-by-step explanation:

1. Problem 8

Draw a line segment connecting the center of the circle, X, to A. This is the radius of the circle

The points ABX form a right triangle with AX as the hypotenuse and AB, BX as the legs of the right triangle

By the Pythagorean theorem
hypotenuse² = sum of the squares of the two legs

Plugging in line segment references

AX² = AB² + BX²

We are given AC = 8, BX = 3

Since the segment BX intersects AC at right angles, AB = BC = AC/2

So AB = 8/2= 4

Plugging these values into the Pythagorean formula
AX² = AB² + BX²

AX² = 4² +3²

AX² = 16 + 9

AX² = 25

Draw a line connecting X and D
The points DEX form a right triangle with DX as the hypotenuse and EX and DE as the legs

Again, by the Pythagorean theorem

DX² = DE² + EX²

But DX is the radius of the circle so it must be the same as AX

Substitute for DX in terms of AX
DX² = DE² + EX²

=> AX² = DE² + EX²

But AX² = 25 and EX = 2 giving EX² = 4

Therefore

AX² = DE² + EX² becomes
25 = DE² + 4

DE² = 25 - 4

DE² = 21

DE = √21

This is choice C

Problem 9

7. Melissa wants to check the accuracy of the finance charge on her promissory note. She has a $6,000, four-year loan at an APR of 10%. A. What is the monthly payment? b. What is the total amount of the monthly payments? c. What is the finance charge?​

Answers

A. Melissa's monthly payment is approximately $146.89.

B. The total amount of the monthly payments over the four-year period is approximately $7,052.72.

C. The finance charge on the loan is approximately $1,052.72.

What is simple interest?

The interest on a loan or principal amount can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more.

To calculate the monthly payment, we can use the formula:

Monthly payment = [P x r x (1 + r)ⁿ] / [(1 + r)ⁿ⁻¹]

where P is the principal (the amount of the loan), r is the monthly interest rate, and n is the number of monthly payments.

A. To find the monthly payment, we first need to calculate the values of r and n.

Since the APR is 10%, the monthly interest rate is 10% / 12 = 0.00833 (rounded to 5 decimal places).

The number of monthly payments over four years is 4 x 12 = 48.

Using these values, we can calculate the monthly payment:

Monthly payment = [6000 x 0.00833 x (1 + 0.00833)⁴⁸] / [(1 + 0.00833)⁴⁸⁻¹]

Monthly payment ≈ $146.89

So Melissa's monthly payment is approximately $146.89.

B. To find the total amount of the monthly payments, we can multiply the monthly payment by the number of payments:

Total amount of monthly payments = Monthly payment x Number of payments

Total amount of monthly payments = $146.89 x 48

Total amount of monthly payments ≈ $7,052.72

So the total amount of the monthly payments over the four-year period is approximately $7,052.72.

C. To find the finance charge, we can subtract the original principal from the total amount of the monthly payments:

Finance charge = Total amount of monthly payments - Principal

Finance charge = $7,052.72 - $6,000

Finance charge ≈ $1,052.72

So the finance charge on the loan is approximately $1,052.72.

A container ship left port last week carrying some goods that weighed a total of 60,010 tons. Today, it stopped in another port to unload. The weight of the goods on the ship is now 30,005 tons. By what percent has the weight of the goods on the ship decreased?

Answers

The weight of the goods on the ship decreased by 50 percent.

To find the percentage decrease in the weight of goods on the ship, we need to calculate the difference between the initial weight and the final weight, divide it by the initial weight, and then multiply by 100 to get the percentage decrease.

The initial weight of the goods on the ship was 60,010 tons and the final weight after unloading was 30,005 tons.

The difference between the initial weight and the final weight is 60,010 - 30,005 = 30,005 tons.

To find the percentage decrease, we divide the difference by the initial weight:

30,005 / 60,010 = 0.5

Multiplying by 100 gives us the percentage:

0.5 x 100 = 50%

Therefore, the weight of goods on the ship has decreased by 50 percent.

In conclusion, the percentage decrease in the weight of goods on the ship is 50 percent. This means that the ship has unloaded half of its initial weight and now carries only half of the weight it carried when it left the port last week. This calculation can be helpful for the shipping company to determine the efficiency of their transportation and to plan for future shipments.

How does quadrilateral 1 move to quadrilateral 2?

The correct pair of transformations that moves quadrilateral 1 to quadrilateral 2 is option d: translate it 8 units to the right, then reflect it over the line y = -3.

First, by translating it 8 units to the right, all points of quadrilateral 1 will shift horizontally to the right by 8 units, maintaining their relative positions.

Next, reflecting it over the line y = -3 will result in a vertical flip of the shape. This reflection will change the orientation of the quadrilateral while keeping the translated positions intact.

Together, these two transformations will precisely move quadrilateral 1 to quadrilateral 2. Therefore, option d is the correct choice.

Answers

If a population is normal with a variance of 99, the necessary sample size is 7 (Option B).

To find the necessary sample size for a given confidence level and margin of error, we can use the formula:

n = (Z² * σ²) / E²

where n is the sample size, Z is the Z-score corresponding to the desired confidence level, σ² is the population variance, and E is the margin of error.

In this case, the population variance (σ²) is 99, the desired confidence level is 68.26%, and the margin of error (E) is 4 units. The Z-score corresponding to a 68.26% confidence level is approximately 1, as it is close to one standard deviation from the mean in a normal distribution.

Now, we can plug the values into the formula:

n = (1² * 99) / 4²
n = (1 * 99) / 16
n = 99 / 16
n ≈ 6.19

Since we cannot have a fraction of a sample, we round up to the nearest whole number, which is 7. So, the necessary sample size is 7 (Option B).

Gray made a $3,500 tax-deductible contribution to his individual retirement account (IRA). Assuming he is in a 28 percent tax bracket, how much will this contribution save him on his taxes?

Answers

Gray's $3,500 tax-deductible contribution to his IRA will save him $980 on his taxes.

When Gray contributes $3,500 to his individual retirement account (IRA), it is considered a tax-deductible contribution. This means that the amount contributed is deducted from his taxable income, reducing the amount of taxes he owes.

Since Gray is in the 28 percent tax bracket, this means that for every dollar of taxable income, he pays 28 cents in taxes. To calculate the tax savings from his $3,500 IRA contribution, we need to multiply the contribution amount by his tax rate:

$3,500 (contribution) x 0.28 (tax rate) = $980 (tax savings)

In this case, Gray's $3,500 tax-deductible contribution to his IRA will save him $980 on his taxes. By contributing to his IRA, Gray not only invests in his future retirement but also takes advantage of the tax benefits associated with these accounts. In the end, he reduces his taxable income and, consequently, the amount of taxes he needs to pay.

it is A=(BxH)/2. This shows that in every quadrilateral there are two
triangles.
There are many different types of quadrilaterals and they all share the
similarity of having four sides, two diagonals, and the sum of their interior
angles is 360 degrees. They all have relationships to one another, but
they are not all exactly alike and have different properties.


answer right if not I will report or banned you ​

Answers

Quadrilaterals have four sides, two diagonals, and the sum of their interior angles is 360 degrees. They can be related to triangles through the fact that each triangle has a total of 180 degrees and a quadrilateral has 360 degrees, so there are two triangles in a quadrilateral with their angles adding up to 360 degrees.

However, triangles and quadrilaterals differ in terms of their area formulas, where the area of a quadrilateral is calculated as the product of its base and height (A = BxH), while the area of a triangle is half the product of its base and height (A = (BxH)/2). Quadrilaterals have different types and properties, although they share the common characteristics mentioned above.

- Quadrilaterals have four sides and two diagonals. The sum of the interior angles in a quadrilateral is always 360 degrees.

- Triangles have three sides and the sum of their interior angles is always 180 degrees.

- The relationship between triangles and quadrilaterals is based on the fact that a quadrilateral can be divided into two triangles. Each triangle within the quadrilateral contributes 180 degrees to the total sum of 360 degrees.

- The formula for calculating the area of a quadrilateral is A = BxH, where A represents the area, B represents the base, and H represents the height.

- In contrast, the formula for calculating the area of a triangle is A = (BxH)/2, where A represents the area, B represents the base, and H represents the height. This formula demonstrates that the area of a triangle is half the area of a quadrilateral with the same base and height.

- While all quadrilaterals share the characteristics of having four sides, two diagonals, and interior angles summing up to 360 degrees, they have different types and properties.

Examples of quadrilaterals include squares, rectangles, parallelograms, trapezoids, and rhombuses. Each type has its own unique properties and relationships to other quadrilaterals.

In conclusion, quadrilaterals and triangles are related through the concept of dividing a quadrilateral into two triangles. They differ in their area formulas, and although all quadrilaterals have four sides, two diagonals, and interior angles summing up to 360 degrees, they have different types and properties.

Simplify and evaluate

Answers

Answer:

In simplified form: 1/27

Evaluated: 0.037

Step-by-step explanation:

To simplify and evaluate 81^(-3/4), we use the rule that (a^m)^n = a^(mn) and rewrite the expression as (3^4)^(-3/4). Then, we use the rule that a^(-n) = 1/(a^n) to get:

81^(-3/4) = (3^4)^(-3/4) = 3^(-3) = 1/(3^3) = 1/27

Therefore, 81^(-3/4) simplifies to 1/27 and evaluates to 0.037

According to researchers one of the primary reasons relationship sour is that people stop listening to one other assumed that the relative frequency distribution for the length of time couples in conflict listen to each other has a mean of eight seconds and standard deviation of five seconds in sample of 37 couples in conflict let X represent the main of length of time the couples listen to each other what is the sample distribution of X

Answers

The square root of the sample size (n=37), which is approximately 0.820 seconds:

X ~ N(8, 5/√37)

The sample distribution of the mean, denoted as X, is the distribution of all possible sample means of a certain sample size taken from a population. In this case, we have a population of couples in conflict, and we have a sample size of 37. The mean length of time couples in conflict listen to each other is known to be 8 seconds with a standard deviation of 5 seconds.

Since we have a large enough sample size (n=37), we can assume that the sample mean follows a normal distribution according to the Central Limit Theorem. The Central Limit Theorem states that the sample means from a large enough sample size will be approximately normally distributed regardless of the population distribution, given that the samples are independent and randomly selected.

Thus, the sample distribution of X can be represented by a normal distribution with a mean of 8 seconds (same as the population mean) and a standard deviation of 5 seconds divided by the square root of the sample size (n=37), which is approximately 0.820 seconds:

X ~ N(8, 5/√37)

BC =

Answers

The measurement of BC in the given figure is 4√2.

Given is figure we need to find the measurement of BC,

∠GBC = ∠CDF = 45° [alternate angles]

So, in triangle DCF,

Cos 45° = DF/DC

1/√2 = DF/12√2

DF = 12

Now we see that the triangles DCF and BCG are similar triangles by AA rule,

So, according to the definition of similar triangles,

DC/BC = DF/BG

12√2/BC = 12/(7-3)

12√2/BC = 12/4

12√2/BC = 3

3BC = 12√2

BC = 4√2

Alternatively, you can find the value of BC, using the trigonometric ratios in triangle GBC,

Cos 45° = GB/BC

GB = 7-3 = 4

Therefore,

Cos 45° = 4/BC

1/√2 = 4/BC

BC = 4√2

Hence the measurement of BC in the given figure is 4√2.

The solution to the equation is x = 15.

(a)How to rewrite the exponential equation?

To rewrite the exponential equation using the same base, we need to express both 8 and 32 as powers of the same base. Since both 8 and 32 are powers of 2, we can rewrite the equation as:

[tex](2^3)^(2x) = (2^5)^(x+3)[/tex]

Here, we used the fact that[tex](a^b)^c = a^(b*c)[/tex]to simplify the exponents. We also used the property that 8 is equal to 2 raised to the power of 3, and 32 is equal to 2 raised to the power of 5.

(b)How to solve for x?

Now that we have rewritten the equation with the same base, we can equate the exponents on both sides of the equation to solve for x:

[tex]2^(6x) = 2^(5x + 15)[/tex]

Since the bases on both sides of the equation are equal, we can equate the exponents and solve for x:

6x = 5x + 15

Subtracting 5x from both sides, we get:

x = 15

Therefore, the solution to the equation is x = 15.
