Answers

Answer 1

Morgan's supply of raisins is approximately 4.62 pounds.

What is the equivalent expression?

Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.

Let's start by setting up an equation based on the given information:

14/48 + 38/48 = 5/x

Here, x represents the total supply of raisins in pounds.

To solve for x, we can first combine the fractions on the left-hand side of the equation:

52/48 = 5/x

Next, we can simplify by cross-multiplying:

52x = 48 x 5

52x = 240

Finally, we can solve for x by dividing both sides by 52:

x = 240/52

x ≈ 4.62

Therefore, Morgan's supply of raisins is approximately 4.62 pounds.

A rocket is launched in the air. Its height in feet is given by h(t)=−16t^2 +24t where
t represents the time in seconds after launch. How long is the rocket in the air?

Answers

Taking into account the zeros of a quadratic function, the time of the rocket when it is in the air is equal to 1.5 seconds.

Zeros of a function

The points where a polynomial function crosses the axis of the independent term (x) represent the so-called zeros of the function.

The zeros represent the roots of the polynomial equation that is obtained by making f(x)=0.

In a quadratic function that has the form:

f(x)= ax² + bx + c

the zeros or roots are calculated by:

[tex]x1,x2=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]

Time of he rocket in the air

A rocket launched with height function h(t)= -16t²+ 24t

where

't' represents the time in seconds'h' is the height of rocket.

Time for which rocket is in the air given by h(t) = 0, so:

0= -16t²+ 24t

where:

a= -16b= 24c= 0

Solving:

[tex]x1=\frac{-24+\sqrt{24^{2} -4x(-16)x0} }{2x(-16)}[/tex]

[tex]x1=\frac{-24+\sqrt{24^{2}} }{2x(-16)}[/tex]

A bus traveled on a level road for 3 hours at an average speed 20 miles per hour faster than it traveled on a winding road. The time spent on the winding road was 2 hours. Find the average speed on the level road if the entire trip was 290 miles.

Answers

Answer:

Let's call the average speed on the winding road "x". Then, the average speed on the level road is "x + 20".

We know that the bus traveled on the winding road for 2 hours, so the distance traveled on the winding road is:

distance = rate × time = x × 2 = 2x

We also know that the bus traveled on the level road for 3 hours at an average speed of "x + 20", so the distance traveled on the level road is:

distance = rate × time = (x + 20) × 3 = 3x + 60

The total distance traveled is 290 miles, so we can write:

2x + 3x + 60 = 290

Combining like terms and solving for x, we get:

5x + 60 = 290

5x = 230

x = 46

Therefore, the average speed on the winding road is 46 mph, and the average speed on the level road is:

x + 20 = 46 + 20 = 66 mph.

The point (2, 7) belongs to the solution region of the system of inequalities.

What is inequalities?

In mathematics, an inequality is a mathematical statement that indicates that two expressions are not equal. It is a statement that compares two values, usually using one of the following symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), or "≥" (greater than or equal to).

The system of inequalities given is:

y > 1.5x + 4

y > -x + 6

One point that belongs to the solution region of this system of inequalities is (2, 7).

To check if this point satisfies the system of inequalities, we can substitute the values of x and y into each inequality:

For the first inequality, y > 1.5x + 4, we have:

7 > 1.5(2) + 4

7 > 7

This is true, so the point (2, 7) satisfies the first inequality.

For the second inequality, y > -x + 6, we have:

7 > -(2) + 6

7 > 4

This is also true, so point (2, 7) satisfies the second inequality.

Therefore, points (2, 7) belong to the solution region of the system of inequalities.

A game has a spinner with 8 equal- sized sections. The results of 450 spins are shown in the table. Part Frequency 1 58 2 52 3 39 4 77 5 50 6 43 7 60 8 71

For Which Number is the number difference between the theoretical probability and experimental probability greatest?Explain

Answers

The theoretical probability of each section is 1/8, since there are 8 equal-sized sections on the spinner. To find the theoretical frequency, we multiply the theoretical probability by the total number of spins:

Theoretical frequency = (1/8) x 450 = 56.25

We can then calculate the experimental probability for each section by dividing the frequency by the total number of spins:

Experimental probability = Frequency/Total number of spins

Using this formula, we can calculate the experimental probabilities for each section:

Part 1: Experimental probability = 58/450 ≈ 0.129

Part 2: Experimental probability = 52/450 ≈ 0.116

Part 3: Experimental probability = 39/450 ≈ 0.087

Part 4: Experimental probability = 77/450 ≈ 0.171

Part 5: Experimental probability = 50/450 ≈ 0.111

Part 6: Experimental probability = 43/450 ≈ 0.096

Part 7: Experimental probability = 60/450 ≈ 0.133

Part 8: Experimental probability = 71/450 ≈ 0.158

To find the number with the greatest difference between the theoretical and experimental probability, we can calculate the difference between the two probabilities for each section:

Part 1: |0.125 - 0.129| = 0.004

Part 2: |0.125 - 0.116| = 0.009

Part 3: |0.125 - 0.087| = 0.038

Part 4: |0.125 - 0.171| = 0.046

Part 5: |0.125 - 0.111| = 0.014

Part 6: |0.125 - 0.096| = 0.029

Part 7: |0.125 - 0.133| = 0.008

Part 8: |0.125 - 0.158| = 0.033

As we can see, the greatest difference between the theoretical and experimental probability is for Part 4 with a difference of 0.046. This indicates that the experimental frequency for Part 4 is significantly different from the theoretical frequency, which may suggest that the spinner is biased towards that section.

Which type of function best models the data in each table? Use differences or ratios. X-0, 1, 2, 3, 4
Y-0,1.5,6,13.5,24

Answers

Answer:

To determine the type of function that best models the data in the table, we can observe the differences or ratios between successive values of y.

Using differences:

The first differences between successive values of y are:

1.5 - 0 = 1.5

6 - 1.5 = 4.5

13.5 - 6 = 7.5

24 - 13.5 = 10.5

The second differences between successive values of y are:

4.5 - 1.5 = 3

7.5 - 4.5 = 3

10.5 - 7.5 = 3

Since the second differences are constant, the function that best models the data is a quadratic function.

Using ratios:

The ratios between successive values of y are:

1.5/0 = undefined

6/1.5 = 4

13.5/6 = 2.25

24/13.5 ≈ 1.78

Since the ratios are not constant, the function that best models the data is not an exponential function.

Therefore, the type of function that best models the data in the table is a quadratic function. We can try to find a quadratic function of the form y = ax^2 + bx + c that passes through the given points. Using the first three points, we get the system of equations:

a(0)^2 + b(0) + c = 0

a(1)^2 + b(1) + c = 1.5

a(2)^2 + b(2) + c = 6

Solving this system of equations, we get:

a = 3/2

b = 0

c = 0

Therefore, the quadratic function that best models the data is y = (3/2)x^2.

Answers

The solution of compound interest problem using formula of amount  is

Anna have$2,734 more money than  Hudson.

what is compound interest ?

Compound interest is a type of interest in which the interest gained is added to the principal sum before the interest for the subsequent period is calculated using the updated total sum. In other words, in addition to the initial principal, the accumulated interest from prior periods is also taken into account for calculating interest. As a result, as time passes, the interest earned increases, increasing the total amount earned or due. Savings accounts, loans, and investments frequently use compound interest.

According to given information

For continuous compounding, the formula is:

A = Pe^(rt)

Where:

A = the amount after t years

P = the principal amount

r = the annual interest rate (as a decimal)

t = the time in years

For daily compounding, the formula is:

A = P(1 + r/n)^(nt)

Where:

A = the amount after t years

P = the principal amount

r = the annual interest rate (as a decimal)

n = the number of times compounded per year

t = the time in years

Using these formulas, we can calculate the amount that Anna and Hudson will have after 10 years, and then find the difference between them.

For Anna's investment:

r = 8.5% = 0.085 (as a decimal)

t = 10 years

P = $69,000

A = Pe^(rt) = 69000 * e^(0.085*10) = $156,794.63

For Hudson's investment:

r = 8 3/8% = 8.375% = 0.08375 (as a decimal)

n = 365 (daily compounding)

t = 10 years

P = $69,000

A = P(1 + r/n)^(nt) = 69000(1 + 0.08375/365)^(365*10) = $154,060.52

Therefore, the difference between the two amounts is:

$156,794.63 - $154,060.52 = $2,734.11

So Anna will have approximately $2,734 more in her account than Hudson after 10 years.

Answers

The equation that represents the cost of the call in dollars is option d. 0.75 + 0.15(x - 3).

What is linear equation?

A linear equation has the formula y = mx + b, where x and y are variables, m is the angle of the line's slope, and b denotes the y-intercept (the location where the line crosses the y-axis). On a graph, this equation represents a straight line.

The y-intercept of a linear equation, which is determined by the value of b, is first plotted on a graph. The slope is then used to determine further points along the line. How much y changes for each unit of x is indicated by the slope. For instance, if the slope is 2, then y grows by 2 for every unit increase in x.

Given that, a certain phone call costs 75 cents for the first three minutes plus 15 cents for each additional minute.

Let us suppose number of minutes = x.

Then,

Cost = 0.75 + 0.15(x - 3)

To calculate the percentage increase of a value from an initial value to a final value, you can use the following formula:

increase in percentage = ((final value - initial value) / initial value) x 100%

Percentage increase is useful in a variety of contexts, including: Finance, Sales, Economics, Science, Education. Percentage increase is a useful tool for measuring growth or change over time and comparing different values.

To find the percentage increase, we first need to calculate the difference between the two numbers:

20.49 trillion - 4.00 trillion = 16.49 trillion

Next, we can divide the difference by the original amount (4.00 trillion) and multiply by 100 to get the percentage increase:

(16.49 trillion / 4.00 trillion) * 100 = 412.25%

Therefore, 20.49 trillion is 412.25% larger than 4.00 trillion.

Suppose 128 ounces of a radioactive substance exponentially decays to 28 ounces in 6 hours. What is the half-life of the substance? The half-life is:

Answers

Answer:

half-life ≈ 2.74

Step-by-step explanation:

One formula we can use for half life is,

N(t) = No * (1/2)^(t / t_1/2), where

N(t) is the amount remaining, No is the initial amount,1/2 is the base t is the time, and t_1/2 is the half life

We already know that N(t) = 28, No = 128, the base is 1/2, and t is 6.  Thus, we must solve for t_1/2 using the following equation:

28 = 128 * (1/2) ^ (6 / t_1/2)

Step 1:  Divide both sides by 128 to clear 128 on the right-hand side of the equation:

(28 = 128 * (1/2) ^ (6 / t_1/2) / 128

0.21875 = (1/2) ^ (6 / t_1/2)

Step 2:  Take the natural log (ln) of both sides:

ln (0.21875) = ln (1/2 ^ (6 / t_1/2))

Step 3:  According to the rules of logs, since we're taking the natural log of ln (1/2 ^ 6 / t_1/2, we can bring down the 6 / t_1/2 and it will now act like a coefficient:

ln (0.21875) = 6 / t_1/2 * ln (1/2)

Step 4:  Divide both sides by ln (1/2) to clear ln (1/2) on the right-hand side of the equation:

(ln ( 0.21875) = 6 / t_1/2 * ln (1/2)) / ln (1/2)

ln (0.21875) / ln (1/2) = 6 / t_1/2

Step 5:  You can cross multiply, which appears easier when you use the vertical fraction form instead of the horizontal fraction form.

[tex]\frac{ln(0.21875)}{ln(1/2)}=\frac{6}{t_{1/2} }\\ \\ t_{1/2}*ln(0.21875)=6*ln(1/2)[/tex]

Step 6:  Finally, you can now divide both sides by ln (0.21875) to isolate t_1/2 and to find the half-life.  I simply rounded to the nearest hundredth, but I'll provide the entire half-life number so you can round as liberally as much as you need or would like

(t_1/2 * ln (0.21875) = 6 * ln (1/2)) / ln (0.21875)

t_1/2 = (6 * ln (1/2) / ln (0.21875)

t_1/2 = 2.736420983 hours

t_1/2 = 2.74 hours

The only real difference between the longer number and the rounded number is that the longer answer gives a more exact answer when you plug it in, but the rounded answer seems to make more sense to write:

Result when plugging in exact answer for t_1/2:

N (2.736420983) = 128 (1/2) ^ (6 / 2.736420983) = 28

Result when plugging in rounded answer for t_1/2:

N (2.74) = 128 (1/2) ^ (6 / 2.74) = 28.05564116

The solution to the word problems are:

1) ∠JML = 63°

2) The center of the circle is (4, -4) and Radius = 4

3) The required measurement of the table cloth should be:

48 in x 36 in

4) The correct option of the similar triangles is:

UY/UV = UZ/ZW

How to solve algebraic word problems?

1) The angle subtended by an arc at the Centre is twice the angle subtended at the circumference . More simply, the angle at the centre is double the angle at the circumference. Thus:

∠JML = 126/2 = 63°

2) The general formula for equation of a circle is expressed as:

(x - h)² + (y - k)² = r²

where:

(h, k) is the coordinate of the center of the circle

r is the radius

We are given the circle equation as:

(x + 4)² + (y - 4)² = 16

This can be rewritten as:

(x + 4)² + (y - 4)² = 4²

Thus:

Coordinates of center = (4, -4)

Radius = 4

3) The required measurement of the table cloth should be:

48 in x 36 in

4) Since both triangles are similar, then it means ratio of corresponding sides will be equal and as such:

UY/UV = UZ/ZW

The graph and table each show a proportional relationship between the number of miles traveled and the
advertised number of gallons of gas used for the two car models, A and B, respectively. Based on the
graph and table, car A can travel how many times the distance car B can travel when both cars use
1 gallon of gas? Write your answer as a decimal.
Enter your answer in the box
1.25

Answers

To answer this question, we need to compare the ratios of miles traveled to gallons of gas used for car A and car B when they both use 1 gallon of gas.

For car A, we can see from the graph that 50 miles are traveled for every 2 gallons of gas used, or in other words, 25 miles are traveled for every 1 gallon of gas used. Therefore, car A can travel 25 times the distance for 1 gallon of gas.

For car B, we can see from the table that 40 miles are traveled for every 2 gallons of gas used, or in other words, 20 miles are traveled for every 1 gallon of gas used. Therefore, car B can travel 20 times the distance for 1 gallon of gas.

To compare the two ratios, we can divide the ratio of miles traveled to gallons of gas used for car A by the ratio for car B:

25/20 = 1.25

Therefore, car A can travel 1.25 times the distance car B can travel when both cars use 1 gallon of gas.
