Caroline swam 525 meters in 5 minutes at a constant speed. At what speed was she swimming?

Answers

Answer 1

She was swimming at 105 meters

Answer 2

If you want to know how fast she was going per minute then you divide how far she went by how long she took. So 525 divided by 5 and it equals 105.

Answers

Well the probability of rolling a six on it would be 1/20.

So, if you're rolling it 1,000 times, 1,000 x 1/20 = 50.

A store offers a $900 to buy a computor the terms of the loan are 9% simple interest and equal monthly payments for three years what is the monthly payment

Answers

The monthly payment should be 20.25

Hey there! Hello!

For this problem, I'm going to assume that the 9% interest is a yearly rate. Please let me know if this assumption isn't correct, and we'll take it from there.

To calculate the full payment including the interest, all you need to do is multiply the $900 by 9%, or 0.09, to get $81. Since this is a yearly thing, we'll multiply 81 by 3 to represent 3 years, and we'll get $243. The total amount a customer will have to pay for the computer is $1,143, which is the interest plus the original price.

Now, for the monthly rate, you would need to divide that amount by 36, which is how many months are in three years. In order to pay the amount for the computer off in three years, a customer would have to pay $31.75 per month.

I hope this helped you out! Feel free to ask any additional questions if you have any. :-)

each week,steven gets an allowance of $8 plus $3 for each chore he does. his younger sister jill gets an allowance of $6 plus $2 per chore. write an expression for how much their parents give steven and jill each week if they do the same number of chores.

Answers

the allowance expression would be 3x+8=2x+6

Final answer:

The expression representing the total weekly allowance Steven and Jill receive for doing the same number of chores is 14 + 5c, where c represents the number of chores done.

Explanation:

The question asks for an expression to represent the total allowance that Steven and Jill receive each week if they do the same number of chores. Steven gets a fixed allowance of $8 plus an additional $3 for each chore he completes, while Jill gets a fixed allowance of $6 plus $2 for each chore she completes.

Let's represent the number of chores they each do with the variable c. The expression for Steven's weekly allowance would be 8 + 3c, and the expression for Jill's weekly allowance would be 6 + 2c. To find the total combined allowance, we simply add the two expressions:

8 + 3c + 6 + 2c

Simplifying this expression, we combine like terms:

14 + 5c

This expression represents the total weekly allowance that their parents give to Steven and Jill together, if they do the same number of chores.

Explain step by step =) Harry rides his bike 25 3/8 miles. Karen rides her bike 25 2/5 miles. Who rides farther?

Answers

To answer this question we need to use subtraction.
we need to make the denominators the same.
In order to make them the same we need to find the least common multiple, of 8 and 5.
The least common multiple(the smallest shared value of the two numbers) is 40.

Next we divide our old denominator 5 by 40, which gives us 8, we multiply 8 by the numerator 2, which gives us 16. So now we have 16/20. We have to do the same to the other side. 8÷40 = 5. 5 x 3 = 15. Now we have 15/20.

Now we have a brand new equation, 16/40 - 15/40. The answer is 1/40.
In a fraction the answer is 1/40, so Karen rides her bike further.

In decimal form the answer is 0.025.

Elysse paid for her sandwich and drink with a $10 bill and received $0.63 in change. The sandwich cost $7.75 and sales tax was $0.47. What was the cost of her drink?

Answers

Okay, first you will have to subtract every thing together:
10 - 7.75 = 2.25
2.25 - 0.47 = 1.78
So the cost of her drink is $1.78
Hope This Helps!!
:)

Given

Elysse paid for her sandwich and drink with a $10 bill and received $0.63 in change.

The sandwich cost $7.75 and sales tax was $0.47.

Find out the cost of her drink

To proof

Let the cost of her drink be x.

As given in the question

Elysse paid for her sandwich and drink with a $10 bill and received $0.63 in change.

Elysse paid for her sandwich and drink = 10 - 0.63

= $ 9.37

sandwich cost $7.75 and sales tax was $0.47

Than the equation becomes

x = 9.37 - (7.75 + 0.47)

x = 9.37 - 8.22

x = $ 1.15

The cost of the drink is $ 1.15.

Hence proved

what you want to do here is plug 2 in for x. when a question asks you to evaluate a certain equation at a certain number, it's just asking you to plug the value in for your variable. i'm assuming that 12x + 8 is meant to be set over 4 as a fraction.

(12(2) + 8)/4 ... figure out the top first. 12*2 = 24, 24 + 8 = 32.

32/4 = 8, so your correct choice is D.

Final answer:

To evaluate the expression (12x + 8) / 4 for x = 2, you multiply 12 by 2, add 8, and then divide by 4. The final answer is 8, which corresponds to option D.

Explanation:

To evaluate the expression (12x + 8) / 4 for x = 2, you substitute the value of x into the expression and then simplify. First, multiply 12 by 2 to get 24, then add 8 to get 32. After that, divide 32 by 4 to get the final answer.

Here is the step-by-step calculation:

Substitute x with 2: (12*2 + 8) / 4.Multiply 12 by 2: (24 + 8) / 4.Add 24 and 8: 32 / 4.Divide 32 by 4: 8.

A rectangular garden sits next to a house. Three sides of the garden are fenced, and the fourth side is the house. The length of the garden is 9 meters. A total of 21.5 meters of fencing is used. If w stands for the width of the garden in meters, which equation can be used to find its width?

Answers

To find the width of the rectangular garden, use the equation 2w + 9 = 21.5, which leads to a width of 6.25 meters after solving step by step. The total fencing used is 21.5 meters for the three sides, with the fourth side being the house.

Finding the Width of the Rectangular Garden

Given that three sides of the rectangular garden are fenced and the fourth side is the house, let's break down the problem step by step:

The length of the garden is given as 9 meters.A total of 21.5 meters of fencing is used for the three sides.We need to find the width w of the garden.

Since only three sides are fenced, the total length of the fencing is the sum of two widths and one length of the garden. Therefore, we can write this equation:

2w + 9 = 21.5

To find w, we solve the equation as follows:

Subtract the length from the total fencing: 2w = 21.5 - 9Calculate the difference: 2w = 12.5Divide by 2 to isolate w: w = 12.5 / 2Final result: w = 6.25 meters

Therefore, the width of the garden is 6.25 meters.

A hurricane has winds that are at least 74 miles per hour. Suppose a tropical storm Hamm has winds that are 42 miles per hour. Write and solve an inequality to find how much the winds must increase before the storm becomes a hurricane.

Answers

42 + x > 74
_

x = 32

Hope this helps!

Final answer:

To find the necessary increase in wind speed for Tropical Storm Hamm to reach hurricane status, set up the inequality 42 + x >= 74, resulting in x >= 32. Hence, the wind speed must increase by at least 32 miles per hour.

Explanation:

To determine how much the wind speed must increase for Tropical Storm Hamm to become a hurricane, we use an inequality. We know that a storm becomes a hurricane when the wind speeds reach at least 74 miles per hour.

Currently, Tropical Storm Hamm has wind speeds of 42 miles per hour. Let's define the variable x as the increase in wind speed needed for the storm to reach hurricane status.

The inequality that represents this situation is:
42 + x ≥ 74

Now, we solve for x:

Subtract 42 from both sides of the inequality: x ≥ 74 - 42

Simplify: x ≥ 32

Therefore, the wind speed must increase by at least 32 miles per hour for Tropical Storm Hamm to become a hurricane.

A ceramic tile is in the shape of a triangle. The angle measurements of this triangle are 30 degrees, 60 degrees, and 90 degrees. The leg across from the 30 degree angle is 6.25 cm long. How long is the hypotenuse of this triangle?

Answers

Ratio of 30-60-90 triangles in terms of side lengths is 1-[tex] \sqrt{3} [/tex]-2

So, the side across the 30-degree angle is 6.25.
Thus, the side across the 90-degree angle (hypotenuse) is 12.5.

A 30 60 90 triangle is a special triangle that has simple proportions for it's side lengths. The short leg to long leg ratio is 1:sqrt(3); the short leg to hypotenuse ratio is 1:2. If the length of the short leg (across from the 30 degree angel) is 6.25 cm long, then the length of the hypotenuse is twice that: 12.5 cm.

tim knows the volume and base area of a wooden chest that is in the shape of a rectangular prism. If the volume is 524 cubic unit and the base area is 15 square unit, what is the height of the chest?

Answers

The height of the rectangular prism chest is approximately 34.93 units, calculated using the volume and base area formulas for rectangular prisms.

To find the height of the rectangular prism chest, we can use the formula for the volume of a rectangular prism, which is given by the product of its length, width, and height. Let's denote the height of the chest as h the length as l , and the width as w.

Given that the volume of the chest is 524 cubic units and the base area (length times width) is 15 square units, we have two equations:

1. [tex]$ l \times w $ (base area) $ = 15 $[/tex] square units,

2. [tex]$ l \times w \times h $ (volume) \( = 524[/tex]) cubic units.

From the first equation, we can solve for one variable in terms of the other. Let's solve for l in terms of w :

[tex]\[ l = \frac{15}{w} \][/tex]

Now substitute this expression for l into the second equation:

[tex]\[ \frac{15}{w} \times w \times h = 524 \][/tex]

Simplify:

15h = 524

Solve for h:

[tex]\[ h = \frac{524}{15} \][/tex]

h ≈ 34.93

So, the height of the chest is approximately 34.93 units.

Gina saves quarters. She has $17.75 in quarters. How many quarters does she have? Show your solution in two ways. Use division to show one way. Use words, nnumbers, or models for the second way.

Answers

Gina wants to know how many quarters she has if she has seventeen dollars and seventy-five (17.75)cents in all quarters. To find he number of quarters, you need to divid seventeen dollars and seventy-five cents (17.75) by twenty five cents (0.25) to get her answer.

17.75/0.25=71

Final answer:

Using division and a visual method, it is calculated that Gina has 71 quarters, given she has a total of $17.75.

Explanation:

Gina has $17.75 and since each quarter is worth $0.25, we need to find out how many quarters make up this amount. First, using division we have 17.75 ÷ 0.25 = 71. Therefore, Gina has 71 quarters.

The second method is a more visual and explanatory one. Since each quarter is 25 cents, four quarters make up a dollar. Therefore, if we have $17, that directly translates to 17 x 4 = 68 quarters. We also have 75 cents left which correspond to another 3 quarters (75 ÷ 25 = 3). Adding these together gives us 68 + 3 = 71 quarters. So, either way, Gina has 71 quarters.
