Mark bought 4 notepads with 85 pages each. He used
17 pages. Which equation can be used to find S, the number
of unused pages in Mark's notepads?
A O (4 x 85) + 17 = S
BO (4 x 85) - 17 = 5
C O (4 x 85) * 17 = s
DO (4 x 85) = 17 = s

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
