Maddy is an event coordinator who helps

raise money for a children's hospital. At

last year's event, she sold 1200 tickets at

$8 each.


Part A: This year Maddy will reduce ticket

prices by 25%. What will be the price of a

new ticket? Explain your reasoning.

D

Part B: Based on the new price, how many

more tickets will Maddy need to sell to

raise the same amount of money as last

year? Explain your reasoning.

Answers

Answer 1

The price of a new ticket after reducing the ticket price by 25% is $6. Maddy will need to sell 400 more tickets this year to raise the same amount of money as last year.

Number of tickets sold = 1200

Cost of each ticket = $8

Part A:

If Maddy lowers ticket costs by 25%, The price of a new ticket will be:

Ticket price = $8 - (25% of $8)

Ticket price = $6

The New ticket price will be calculated by multiplying 0.75 for reducing the 25% tickets

New ticket price = $8 x 0.75 = $6

Part B:

To find how many tickets Maddy requires to sell to equal the same amount of money collected in the previous year:

Total revenue = total number of tickets x Ticket price

1200 tickets x $8 per ticket = $9,600

= $9,600 / $6

= 1,600

Total tickets need to sell = 1600-1200 = 400

Therefore we can conclude that Maddy will need to sell 400 more tickets this year.

The buying and selling rate of U. S. Doller ($) in a day are Rs 115. 25 and Rs 116. 5 respectively. How many dollar should be bought and sold to have the profit of $ 10 ? Find it

Answers

To earn a profit of $10, we need to buy and sell 10 dollars.

The difference between the buying and selling rates is the profit margin for the currency exchange. Here, the profit margin is 116.5 - 115.25 = 1.25 Rs per dollar.

To make a profit of $10, we need to buy and sell enough dollars to earn a profit of 1.25*10 = 12.5 Rs.

Let's assume we buy and sell x dollars. Then the cost of buying x dollars is 115.25x Rs, and the revenue from selling x dollars is 116.5x Rs.

So, the profit from buying and selling x dollars is (116.5x - 115.25x) = 1.25x Rs.

We need to find x such that 1.25x = 12.5, which gives x = 10.

Therefore, we need to buy and sell 10 dollars to earn a profit of $10.

Step-by-step explanation:

Since the rate is linear, we can subtract a larger amount of minutes by a smaller one and a larger cost by a smaller one.

For example:

20 - 15 = 5

3.40 - 3.05 = 0.35

Since you want to find the amount it takes per minute, you divide the 5 by 5 to make it one minute. You also divide the 0.35 by 5 in which you get 7.

The ratio of a : b : c : d is 3 : 7 : 2 : 7.

What are the ratios?

The ratios are determined as follows from the data given.

The given data is:

7a = 2b

b = (7/2)a.

a and b have no common factors, thus a must be even and b must be odd.

c : d is 2 : 7

For an integer x, c = 2x and d = 7x

a : d is 3 : 1

So for an integer y, a = 3y and d = y

Substituting into 7a = 2b:

7(3y) = 2(7/2)y a

21y = 7y * b

b = 3a

Substituting these expressions for a and b into c : d = 2:7, we get:

2x : 7x = 3 : 1

2x = 3y and 7x = y

y = 14x/3

a : b : c : d = 3y : 7y : 2x : 7x

a : b : c : d = 3(3y) : 3(7y) : 3(2x) : 3(7x)

Consider the series Σ(1) с (where c is a constant). For which values of c will the series converge, and for which it diverge? Justify your answer, and show all your work. (Hint: Use the root test)

Answers

To determine whether the series Σ(1) с converges or diverges, we can use the root test. The root test states that if the limit of the absolute value of the nth root of the terms of the series approaches a value less than 1, then the series converges. If the limit approaches a value greater than 1, the series diverges. If the limit equals 1, the test is inconclusive and another test should be used.

Using the root test, we have:

lim┬(n→∞)⁡〖|1^(1/n) c| = lim┬(n→∞)⁡|c| = |c|〗

If |c| < 1, then the limit approaches a value less than 1 and the series converges. If |c| > 1, then the limit approaches a value greater than 1 and the series diverges. If |c| = 1, then the test is inconclusive.

Therefore, the series Σ(1) с converges if |c| < 1, and diverges if |c| > 1. If |c| = 1, then another test should be used to determine convergence or divergence.

LA and LB are vertical angles. If mLA=(x+21)° and mLB=(4x-30)°, the find then measure of LB

Answers

Answer:

38 degrees

Step-by-step explanation:

Vertical angles are congruent(equal measures), so mLA = mLB

STEP 1:

Let's use some simple substitution.

mLA = mLB

mLA = x+21, mLB = 4x-30

You plug these two in and get:

x+21 = 4x-30

This is your equation.

STEP 2:

Let's solve our equation!

x+21 = 4x-30

(add 30 to both sides)

x+51 = 4x

(subtract x from both sides)

51 = 3x

(switch order for comprehension)

3x = 51

(divide both sides by 3)

x = 17

Ta-da! You get the measure of x = 17 degrees.

STEP 3:

Let's plug in our value of x to get the value of LB.

mLB = 4x - 30

mLB = 4(17) - 30

mLB = 68 - 30

mLB = 38

How to find the missing parts of the triangle?

To find the missing parts of the triangle, we can use the Law of Sines and Law of Cosines.

First, we can use the Law of Cosines to find angle A:

cos(A) = (b² + c² - a²) / (2bc)

cos(A) = (13.7² + 16.7² - 8²) / (2 * 13.7 * 16.7)

cos(A) = 0.773

A = [tex]cos^-^1^(^0^.^7^7^3^)[/tex]

A ≈ 28.4°

Next, we can use the fact that the sum of the angles in a triangle is 180° to find angles B and C:

B = 180° - A - C

B = 180° - 28.4° - 99.1°

B ≈ 52.5°

C = 180° - A - B

C = 180° - 28.4° - 52.5°

C ≈ 99.1°

Therefore, the missing parts of the triangle are:

(4 marks) (iii) Fatuma sold all the fruits bought on the second market day at a profit of 10% per orange and 15% per mango. Calculate the total amount of money realized for the sales. (2 marks)​

Answers

Answer:Let the cost of an orange and that of a mango during the first market day be Ksh. x and Ksh. y respectively.

From the first market day:

30x + 12y = 936

From the second market day:

15(1.2x) + 20(3/4y) = 780

Simplifying the second equation:

18x + 15y = 780

(ii) Using matrix to find the cost of an orange and that of a mango in the first market day:

Rewriting the equations in matrix form:

|30 12| |x| |936|

|18 15| x |y| = |780|

Multiplying the matrices:

|30 12| |x| |936|

|18 15| x |y| = |780|

|30x + 12y| |936|

|18x + 15y| = |780|

Using matrix inversion:

| x | |15 -12| |936 12|

| y | = | -18 30| x |780 15|

|x| |270 12| |936 12|

| | = |-360 30| x |780 15|

|y|

Simplifying the matrix multiplication:

|x| |1194| |12|

| | = | 930| x |15|

|y|

Therefore, the cost of an orange in the first market day was Ksh. 39 and the cost of a mango in the first market day was Ksh. 63.

(iii) Calculation of the total amount of money realized for the sales:

On the second market day, Fatuma bought 15 oranges and 20 mangoes.

Cost of 15 oranges = 15(1.2x) = 18x

Cost of 20 mangoes = 20(3/4y) = 15y

Total cost of fruits bought on the second market day = 18x + 15y = 18(39) + 15(63) = Ksh. 1629

Profit earned on 15 oranges at 10% = 1.1(1.2x)(15) - (1.2x)(15) = 0.18x(15) = 2.7x

Profit earned on 20 mangoes at 15% = 1.15(3/4y)(20) - (3/4y)(20) = 0.15y(20) = 3y

Total profit earned = 2.7x + 3y

Total amount of money realized for the sales = Total cost + Total profit

= Ksh. 1629 + 2.7x + 3y.

Consider the following planes. 5x - 3y + z = 2, 3x + y - 5z = 4 Find parametric equations for the line of intersection of the planes. (Use the parameter t.) (x(t), y(t), z(t)) = Find the angle between the planes. (Round your answer to one decimal place.)

Answers

the cross product of the normal vectors of the planes will give you the direction vector of the line.

(5,−3,1)×(3,1,−5)=(14,28,14)

Which we can scale down to (1,2,1)

Now we need a point on the line. By inspection we can see that (1,1,0) lies in both planes.

Sometimes it it not that easy. But it is usually pretty easy to find a point in at least one plane and then travel along some line in that plane until we intersect the line in question.

Vector form of the line  L:(x,y,z)=(1,2,1)t+(1,1,0)

In parametric form  x=t+1,y=2t+1,z=t

The parametric equations are (x(t), y(t), z(t)) = (17/34 + 11t/34, 22/34 - 5t/34, 57/34 + 7t/34), where t is a parameter. The angle between the planes is 93.7 degrees.

To find the line of intersection of the planes, we can set the two equations equal to each other and solve for x, y, and z in terms of a parameter t. We can begin by eliminating one variable, say z.

From the first equation, we have z = 2 - 5x + 3y, and substituting this into the second equation gives 3x + y - 5(2 - 5x + 3y) = 4. Simplifying this equation, we get 22x - 14y - 23 = 0. Solving for y in terms of x, we get y = (22/14)x - (23/14).

Substituting this into the first equation and solving for z, we get z = (17/14)x + (57/14). Therefore, we have x = (17/22) + (11/22)t, y = (22/14) - (5/14)t, and z = (17/14)x + (57/14) + (7/22)t. These are the parametric equations for the line of intersection of the planes.

To find the angle between the planes, we can find the angle between their normal vectors.

The normal vector to the plane 5x - 3y + z = 2 is (5, -3, 1), and the normal vector to the plane 3x + y - 5z = 4 is (3, 1, -5). Using the dot product formula, we have cosθ = (5)(3) + (-3)(1) + (1)(-5) / sqrt(5² + (-3)² + 1²) sqrt(3² + 1² + (-5)²), which simplifies to cosθ = -19/34.

Taking the inverse cosine of this value, we get θ = 93.7 degrees, rounded to one decimal place. Therefore, the angle between the planes is approximately 93.7 degrees.

The berry-picking boxes at bingo berry farm have square bottoms that are 8 centimeters on each side. mateo fills his box with raspberries to a height of 6 centimeters. what is the volume of raspberries in mateo's box?

Answers

The volume of raspberries in Mateo's box is 384 cubic centimeters.

To calculate the volume of raspberries in Mateo's box, we need to use the formula for the volume of a rectangular prism, which is length x width x height. In this case, the length and width are both 8 centimeters, as the box has a square bottom. The height is 6 centimeters, as Mateo fills the box to that height with raspberries.

So, the volume of raspberries in Mateo's box is:

Volume = length x width x height
Volume = 8 cm x 8 cm x 6 cm
Volume = 384 cubic centimeters

Therefore, the volume of raspberries in Mateo's box is 384 cubic centimeters. This calculation assumes that the raspberries are tightly packed in the box, without any gaps or air pockets. In reality, the actual volume of raspberries may be slightly less than this, depending on how they are arranged in the box. Nonetheless, this calculation provides a reasonable estimate of the amount of raspberries that Mateo is able to pick and fit in the box.

Answer: We can check whether the expression (x + 18) is a factor of x² - 324 by dividing x² - 324 by (x + 18) using polynomial long division or synthetic division.

Using polynomial long division:

x + 18 │x² + 0x - 324

       -x² - 18x

       ----------

        18x - 324

        18x + 324

        ----------

            0

Since there is no remainder, we can see that (x + 18) is indeed a factor of
x² - 324.

What is the slope of the linear function that models the data in the table? ​

Answers

The slope of the linear function that models the data in the table is -1.5. It was calculated by using the formula for slope (change in y divided by change in x) and plugging in the given coordinates. This means that for every increase of 2 in the x-value, the y-value decreases by 3.

To find the slope of the linear function that models the data in the table, we can use the slope formula

slope = (change in y)/(change in x)

We can choose any two points from the table to calculate the slope. Let's choose the points (-2,6) and (0,3)

change in y = 3 - 6 = -3

change in x = 0 - (-2) = 2

So the slope is

slope = (-3)/(2) = -1.5

Therefore, the slope of the linear function that models the data in the table is -1.5.

Find the interval of convergence of the power series. (Be sure to include a check for convergence at the endpoints of the interval. If the interval of convergence is an Interval, enter your answer using interval notation. If the Interval of convergence is a finite set, enter your answer using set notation.)
Sum = (n!(x+5)^n) / 1 . 3 . 5 ...... (2n-1)

Answers

To find the interval of convergence of the power series, we can use the ratio test:

lim (n->inf) |((n+1)!(x+5)^(n+1)) / (1.3.5....(2n+1))| / |(n!(x+5)^n) / (1.3.5....(2n-1))|

= lim (n->inf) |(x+5)(2n+1)| / (2n+2) = |x+5| lim (n->inf) (2n+1)/(2n+2) = |x+5|

So the series converges if |x+5| < 1, and diverges if |x+5| > 1. Thus the interval of convergence is (-6, -4).

To check for convergence at the endpoints, we can use the limit comparison test with the divergent series:

1/1.3 + 1/1.3.5 + 1/1.3.5.7 + ... = sum (2n-1) terms = inf

At x = -6, we have:

sum (n=0 to inf) (n!(-1)^n)/(1.3.5....(2n-1)) = 1/1 - 1/1.3 + 1/1.3.5 - 1/1.3.5.7 + ... = inf

Since the series diverges at x = -6, the interval of convergence is (-6, -4] using set notation.

At x = -4, we have:

sum (n=0 to inf) (n!(1)^n)/(1.3.5....(2n-1)) = 1/1 - 1/1.3 + 1/1.3.5 - 1/1.3.5.7 + ... = 1 - 1/3 + 1/15 - 1/105 + ...

This is an alternating series that satisfies the conditions of the alternating series test, so it converges. Thus the interval of convergence is (-6, -4] using set notation, or [-6, -4) using interval notation.
To find the interval of convergence of the power series, we'll use the Ratio Test, which states that if the limit L = lim(n→∞) |aₙ₊₁/aₙ| < 1, then the series converges. Here, the series is given by:

Σ(n!(x+5)^n) / 1 . 3 . 5 ... (2n-1)

Let's find the limit L:

L = lim(n→∞) |(aₙ₊₁/aₙ)|
 = lim(n→∞) |((n+1)!(x+5)^(n+1))/(1 . 3 . 5 ... (2(n+1)-1)) * (1 . 3 . 5 ... (2n-1))/(n!(x+5)^n)|

Now, simplify the expression:

L = lim(n→∞) |(n+1)(x+5)/((2n+1))|

For the series to converge, we need L < 1:

|(n+1)(x+5)/((2n+1))| < 1

As n approaches infinity, the above inequality reduces to:

|x+5| < 1

Now, to find the interval of convergence, we need to solve for x:

-1 < x + 5 < 1
-6 < x < -4

The interval of convergence is given by the interval notation (-6, -4). To check the endpoints, we need to substitute x = -6 and x = -4 back into the original series and use other convergence tests such as the Alternating Series Test or the Integral Test. However, the power series will diverge at the endpoints, as the terms do not approach 0. Therefore, the interval of convergence remains (-6, -4).

5. this prism has a right triangle for a base. the volume of the prism is 54 cubic units.
what is the value of h?

Answers

The value of h is 6 units.

The volume of the prism is given by the formula V = 1/3 x (base area) x height. Since the base of the prism is a right triangle, the area of the base is given by A = 1/2 x base x height of the triangle. Therefore, the volume of the prism can be written as V = 1/3 x 1/2 x base x height of the triangle x height of the prism.

Simplifying this expression, we get V = 1/6 x base x height^2. Given that the volume of the prism is 54 cubic units, and substituting the value of the base which is not given as per the formula we get, 54 = 1/6 x base x h^2. Solving for h, we get h = 6 units. Therefore, the value of h is 6 units.

A rectangle with length n is inscribed in a circle of radius 9. Find an expression for the area of the rectangle in terms of n

Answers

Using pythagorean theorem the area of the rectangle in terms of n is given by A = n√(324 - n^2).

In the given scenario, we have a circle with a diameter that is twice the length of the radius, which is stated as 18. The diagonal of the rectangle is also the diameter of the circle, so it measures 18. Let's assume the width of the rectangle as 'w'. By applying the Pythagorean theorem, we can establish the following relationship:[tex]n^2 + w^2 = 18^2[/tex] = 324, where 'n' represents the length of the rectangle.

To solve for 'w', we rearrange the equation: [tex]w^2 = 324 - n^2.[/tex] This equation allows us to calculate the width 'w' of the rectangle when we know the length 'n'.

The area of the rectangle, denoted as 'A', is given by the formula A = nw, where 'n' is the length and 'w' is the width of the rectangle. By substituting the expression for w^2, we obtain: A =[tex]n\sqrt(324 - n^2).[/tex]

This equation represents the relationship between the length 'n' and the area 'A' of the rectangle, taking into account the given information about the diameter of the circle, which is also the diagonal of the rectangle. By solving for 'n' and substituting it into the formula, we can determine the area of the rectangle.

Let the width of the rectangle be w, then by the Pythagorean theorem, we have:

[tex]n^2 + w^2 = 18^2[/tex] = 324

Solving for w, we get: [tex]w^2 = 324 - n^2[/tex]

The area of the rectangle is given by:

A = nw

Substituting the expression for w^2, we get:

A =[tex]n\sqrt(324 - n^2)[/tex]

Which name best describes the polygon with


vertices (0,0), (4,8), (12,8), and (16,0)?

Answers

The polygon described by the given vertices is a trapezoid.

Why is the polygon is given vertices a trapezoid?

A trapezoid is a quadrilateral with at least one pair of parallel sides. In this case, the sides with endpoints (0,0) and (16,0) are parallel to each other, and the sides with endpoints (4,8) and (12,8) are parallel to each other. Therefore, the polygon described by the given vertices is a trapezoid.

In addition to having parallel sides, a trapezoid can have various other properties, such as being isosceles (having two equal sides) or having perpendicular diagonals. However, based solely on the given vertices, we can determine that the polygon is a trapezoid.

A trapezoid has various properties, including having one pair of parallel sides, having one pair of non-parallel sides, and having two pairs of adjacent angles that add up to 180 degrees. It can also be isosceles if the non-parallel sides are equal in length.

The trapezoid is a commonly studied shape in geometry because of its simple properties and its appearance in many real-world applications, such as in architecture and engineering. Trapezoids are used in the design of roofs, bridges, and other structures that require stable, load-bearing shapes.

Only a small percentage of Americans owned cars before the 1940s. By 2017, there were nearly 250 million vehicles for 323 million people, significantly increasing the need for roadways. In 1960, the United States had about 16,000 km of interstate highways. Today, the interstate highway system includes 77,000 km of paved roadways. What percent increase does this represent?

A. 381 percent
B. 792 percent
C. 38 percent
D. 79 percent

Answers

The percent increase in the interstate highway system from 1960 to now is 381%.

option A.

What is the percent increase?

The percent increase from 16,000 km to 77,000 km is difference between the old value and new value divided by the old value expressed in 100%.

percent increase =  100% x (new value - old value) / old value

percent increase = 100% x  (77,000 - 16,000) / 16,000

percent increase = 100% x 61,000 / 16,000

percent increase = 381.25%

Thus, the percent increase in the interstate highway system from 1960 to now is approximately 381%, which is option A.
