Justin solved 15 problems of the recent math quiz. His classmate Jordan solved 3 more problems than Justin. Another classmate of Justin, Jeremy also solved some problems and they all together solved 37 problems. Who solved the most number of problems?

Jordan

Step-by-step explanation:

Problems solved by Jordan = 15 + 3 = 18

Total problems solved = 37

Problems solved by Justin + problems solved by Jordan + problems solved by Jeremy = 37

15 + 18 + problems solved by Jeremy = 37

33 + problems solved by Jeremy = 37

Problems solved by Jeremy = 37 - 33

Problems solved by Jeremy = 4

So, Jordan solved most number of problems

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
