What is (-m)⁻³n if m = 2 and n = -24?
Galina-37 [17]

Answer:

-3

Step-by-step explanation:

(-2)^-3 x (-24)

(-2)^3 becomes 1/(-2)^3 in order to make the negative exponent a positive one.

then, you do 1/-8 (the -8 is the (-2)^3 simplified) x -24

1/-8 x (24) = 24/-8 = -3.

Hope this helps! :)

lord [1]

Hi there! :)

<h2>20%</h2><h2></h2>

To solve, we can simply divide and multiply by 100 to solve for the percentage:

5 / 25     = 5 ÷ 25 = 1/5 or 0.20

Multiply the decimal by 100 to solve for the percentage:

0.20 × 100 = 20%

The diameter of a dome is 28 inches. What is the volume? Leave in terms of pi.
MArishka [77]
To find the volume of a dome, you would have to find the volume of the sphere, theoretically, and then divide it by two. To calculate the volume, we would use the formula 4/3 \pi r^{3}. The radius (r) in this case is half of the diameter which is 14. 4 x 3.14 (pi) = 12.56. 12.56 x 14 x 14 x 14 (2744) = 34464.64. If we divide this number by 3, we get 11488.2133. If we divide this by 2 (to get the dome), we get 5744.10656. Which would be 5744.1 rounded to the nearest tenth.

283.5

So you multiply 6.75 by 21 stools to find the total number of meters. Then you multiply that by 2.
