1/3m- 1- 1/2n when m = 21 and n = 12

1/3m - 1 - 1/2n

= 1/3( 21) - 1 -  1/2 (12)

= 7 - 1 - 6

= 6 - 6

= 0

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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
