If 35% of a number is 98 and 80% of the same number is 224, find 45% of that number.

9514 1404 393

  126

Step-by-step explanation:

If n represents the original number, we have

  (35%)n = 98

  (80%)n = 224

We want to find (45%)n.

  (45%)n = (80% -35%)n = (80%)n -(35%)n

  (45%)n = 224 -98 = 126

45% of the number is 126.

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

56
