what is the value of the expression 8^-2

Answers

Answer 1
It would be 64 if the -2 is an exponent.
Answer 2
The answer is 0.015625. I know that's long, but it's because when you have a negative exponent, you put the number below 1? So in 8^2 you're doing 8^2/1, which is the same thing, but in 8^-2, you're doing 1/8^2. This is 1/64, which is equivalent to 0.015625. I know it's pretty confusing but let me know if you still don't get it :)

If no other money was deposited into or withdrawn from the account, how much was his initial deposit?
PLEASE HELP ME!

Answers

The answer for the first part is 6 years and the answer for the second part is $293.

What is simple interest?

It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.

It is given that:

DeShawn deposited $6500 into a bank account that earned 11.5% simple interest each year.

I = Prt

$4485 = 6500(0.115)(t)

t = 6 years

Rich deposited money into a bank account that earned 2.5% simple interest each year.

I = Prt

14.65 = P(0.025)(2)

P = $293

Thus, the answer for the first part is 6 years and the answer for the second part is $293.

Dreanne uploads 292 pictures to her online album.Her online album shows 12 pictures on each page.How many pages does she scroll through to see all 292 pictures?What does the remainder represent

Answers

Final answer:

Dreanne needs to scroll through 25 pages to see all her 292 pictures. She scrolls through 24 full pages, and the 25th page has the remaining 4 pictures.

Explanation:

To find out how many pages Dreanne has to scroll through to see all 292 pictures in her online album, we need to divide the total number of pictures by the number of pictures per page. We know there are 292 pictures and each page shows 12 pictures.

Dividing 292 by 12, we get:

292 ÷ 12 = 24 R 4

This means Dreanne will have to scroll through 24 full pages of pictures. However, there's a remainder of 4, which means there will be an additional page with only 4 pictures on it. In total, Dreanne will scroll through 25 pages. The remainder represents the number of pictures on the last, non-full page.

A company makes triangular plates for individual slices of pizza. For each plate, the base is 5 inches and the height is 16 inches. The area of the top of the plate is ____ inches squared
I will put best answer for the first person to answer.

Answers

Area of triangle: base x height /2

5x16/2= 40 inches square

Answer: 40 inches square

Final answer:

The area of the top of the triangular pizza plate is calculated using the formula for the area of a triangle (½ × base × height), which results in an area of 40 inches squared.

Explanation:

As we know that:

The area of a triangle can be calculated using the formula:

Area = ½ × base × height.

In this case, the triangular plate has a base of 5 inches and a height of 16 inches. Substituting these values into the formula gives:

Area = ½ × 5 inches × 16 inches = ½ × 80 inches2 = 40 inches2.

Therefore, the area of the top of the plate is 40 inches squared.

Miss Ferguson recorded 17 absences in her class during the first 30 days of school. During the last 60 days of school, she recorded 42 absences. Are the rates equivalent? Explain your reasoning.

Answers

The rates are not equivalent because 60 is double of 30 the absences must be 17 times 2. But 17 times 2 is 34 so they cannot be equivalent.
no because if you look at 30 & 60those are half-friends 30 is half of 60 so, look at 17...      ... keepthat in your head.....           .....  17 x 2 is 34 so 17 is NOT equevilent to 42.

Saeed bought 21 1/2 lb. of ground beef. He used 1/4 of the beef to make tacos and 2/3 of the remainder to make quarter-pound burgers. How many burgers did he make?

If you are asked to find 621 / 59 how do you know the quotient will be greater than 10 before you actually divide?

Answers

Final answer:

You can estimate that the quotient of 621 / 59 is greater than 10 by rounding 59 to 60 and recognizing that 600 divided by 60 equals 10, and then considering that 621 is slightly more than 600 while 59 is slightly less than 60.

Explanation:

To determine if the quotient of 621 / 59 will be greater than 10 before actually dividing, you can estimate using numbers that are easier to work with. The number 59 is close to 60, which is a multiple of 10. If you round 59 up to 60, you can easily see that 600 (10 times 60) would be divided cleanly into 10 parts.

Thus, you can infer that since 621 is slightly higher than 600, and 59 is slightly less than 60, the quotient must be slightly greater than 10.

Jeffrey is buying mulch for a circular flower garden with a diameter of 12 feet. The layer of mulch needs to be 4 inches thick. What is the volume of mulch needed for the flower garden?

Answers

For anyone doing the USA test prep the correct answer is 37.7 cubic feet!

Final answer:

The volume of mulch needed for the flower garden is approximately 37.68 cubic feet.

Explanation:

To find the volume of mulch needed for a circular flower garden, we first need to calculate the volume of the garden. The formula for the volume of a cylinder is V = πr^2h, where r is the radius and h is the height. In this case, the radius is half the diameter, so r = 12/2 = 6 feet. The height is the thickness of the mulch, which is 4 inches or 4/12 = 1/3 feet. Plugging these values into the formula, we get V = π(6)^2(1/3). To simplify further, we can use the approximate value of π as 3.14. Therefore, the volume of mulch needed for the flower garden is approximately 37.68 cubic feet.
