Answer: 63.42

Step-by-step explanation:

Answer:

a. 3

b. h = 1/3d + 3

c. 7 hours because they started at 3 miles and moved at a constant rate of 3 miles per hour

Step-by-step explanation:

for question A it's 3 because they went on a hike from their campsite, not their car and the graph is the distance from their car since the graph starts at 3 this means that the campsite is 3 miles from their car.

for question B it's h = 1/3d because if you look at the graph you can take where two of the points on the line are on a cross-section of the graph and see how many hours and miles there are between the two, then just take the y-intercept or in this case the h intercept and put it after the x or in this case d. Then just simplify the equation, so that the y(d) side is equal to 1, ie: instead of 2y = 8x + 4 its y = 4x + 4.

and finally, for question C, you can just plug the x(d) and y(h) value that is given in this case d = 24, and plug it in so h = 1/3d + 3 becomes h = 24/3 + 3

Answer:

4

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

Let's break down this problem step by step.

First, let's understand what's happening here. There's a carnival game where you can pick one duck from a pond. Each duck has a mark under it that might make you a winner of a prize. Some ducks are marked with large prizes, some with medium, some with small, and the rest don't win you any prize.

The total number of ducks in the pond is 73.

Out of these 73 ducks:

- 5 are marked for a large prize,

- 11 are marked for a medium prize,

- 24 are marked for a small prize.

We are asked to find the theoretical probability of picking a duck that has a medium prize mark. The theoretical probability is basically a fraction that compares the number of ways something can happen with the total number of outcomes.

Here, the number of ways you can win a medium prize is equal to the number of ducks that have a medium prize mark, which is 11.

The total number of outcomes is just the total number of ducks you can choose from, which is 73.

The probability (P) of winning a medium prize is then:

P(medium prize) = (Number of medium-prize ducks) / (Total number of ducks)

= 11/73

To convert this fraction to a decimal, simply divide 11 by 73:

= 11 ÷ 73

≈ 0.1507 (rounded to the nearest thousandth)

So, the probability of winning a medium prize at the duck pond is about 0.151 or 15.1%. Imagine, for every 100 ducks you pick (if there were that many), about 15 of them would win you a medium prize.

The theoretical probability of winning a medium prize at the duck pond is ≈ 0.150

To find the theoretical probability of winning a medium prize at the duck pond, we need to determine the ratio of the number of medium-prize-winning ducks to the total number of ducks in the pond.

The total number of ducks in the pond is given as 73.

The number of medium-prize-winning ducks is given as 11.

Therefore, the probability can be calculated as follows:

Probability of winning a medium prize = (Number of medium-prize-winning ducks) / (Total number of ducks)

Probability of winning a medium prize = 11 / 73

To express the answer as a decimal, we divide 11 by 73:

Probability of winning a medium prize ≈ 0.150

Rounded to the nearest thousandth, the theoretical probability of winning a medium prize at the duck pond is approximately 0.150

Step-by-step explanation:  the second one

Answer: y=5x

Answer:

$7000

Step-by-step explanation:

This problem seems scary at first sight, but don't be intimidated. It is actually pretty simple.

The column of equations (starting with 0.1d) at the right of T(d) is a list of option based on d, the taxable income. If d is less than or equal to (≤) 9875, than the equation is T(d) = 0.1d.

It shows that Noam has 90000 dollars for d, or the taxable income, and Betty has 120000 dollars.

Now, let's find the equations by plugging in 90,000 for d first.

90,000 is greater than 85, 526 and less than 163,300 (85, 526 ≤ 90,000 ≤ 163300).

Then we plug in 120,000 dollar to find the corresponding equation.

120000 is greater than 85, 526 and less than 163, 300 (85, 526 ≤ 120,000 ≤ 163300).

So the chosen equation is:  

T(d) = .24( d -85525) + 14605.5

Plug in the Noam's number for d

T(d) = .24(90,000 - 85, 525) + 14, 605.5

T(d) = .24(4475) + 14,605.5

T(d) = 1074 + 14,605.5

T(d) = 15, 679.5

Now Plug in Betty's number for d

T(d) = .24 (120,000 - 85, 525) +14, 605.5

T(d) = .24( 34475) + 14, 605.5

T(d) = 8274 + 14, 605.5

T(d) = 22, 879.5

We are finding how much more tax does Betty pay, so we subtract               15, 679.5 from 22, 879.5.

22, 879.5 - 15, 679.5 = 7200

Betty pays $7000 more tax than Noam does.        

Answer:

lengh * with is area  3 * 2 1/2 = 7.5

Answer:

155α+81

Step-by-step explanation:

There are two rectangles:

1

area₁ =- (15α+8)(7) = 15α*7 + 8*7 = 105α+56

2

area₂ = (10α+5)(12-7) = (10α+5)(5) = 10α*5 + 5*5 = 50a + 25

Total area = area₁ + area₂

Total area = (105α+56)+(50α+25)

Total area = 105α + 50α + 56 + 25

Total area = 155α + 81

Answer: 26

We would add the total responses recorded in the Girls row, which is equal to 32. We would then subtract it from the total of that row, 38. 38 - 32 is equal to 6. 6 girls chose their answer as English. We can check our work by adding the responses to see if they added up to the total. Now we move to the boys. The Maths column is 5. The boys row is missing 2 things - english and total. We can find the total by subtracting 38 from 70. This is equal to 32. Now, we can add 7 and 5 (12) and subtract from the row total (32). This is equal to 20. 20 boys chose English.

Now we add the girls and boys. 6 + 20 is equal to 26. 26 is your answer.

Answer:30M + 1500 less than or equal to 4500

this should be the right awnser

Step-by-step explanation:

Answer:

100 minutes (or 1 hour and 40 minutes)

Step-by-step explanation:

to start I subtracted 4,500( how much it can hold) by 1,500 (how much it has already) to get 3,000.  

4500 - 1500 = 3000 (300 + 1500 = 4500)

so the pool would need 3,000 more gallons of water to reach the limit,

then divide 3,000 by 30 to know how many 30 gallows would be needed to reach the limit

3,000 ÷ 30 = 100 (100 x 30 = 3,00 so this is correct)

He would need to add water for 100m to avoid exceeding the limit.

That is as far as I know, you can utilize this problem to write an appropriate Inequality, I hope this is helpful!

A) Solving the quadratic equation, we can see that the water droplet will hit the ground after 2 seconds.

B) in this case, the water droplet hits the ground after 1 second.

The height of the water droplet is modeled by the quadratic function:

y = -16*t^2 + 64

It will hit the ground when y = 0, so we need to solve:

0 = -16*t^2 + 64

16*t^2 = 64

t^2 = 64/16

t^2 = 4

t = √4 = 2

So it takes 2 seconds.

B) if now the initial height is 16 ft, then the new equation is:

y = -16*t^2 + 16

Now it will take:

0 = -16*t^2 + 16

16*t^2 = 16

t^2 = 16/16

t = √1  = 1

Now it will take 1 second.

4/10= 40%

The percent that is equivalent to two-fifths is 40%. The correct option is 40%.

To determine the percent equivalent to two-fifths, we need to convert the fraction into a percentage.

The fraction two-fifths can be written as 2/5. To convert this fraction to a percentage, we divide the numerator (2) by the denominator (5) and multiply the result by 100.

2/5 x 100

= 0.4 x 100
