Separate 39 into two parts such that 4 times the smaller exceeds the larger number 6

39 is separated into two parts 9 and 30.

Step-by-step explanation:

To find : Separate 39 into two parts such that 4 times the smaller exceeds the larger number 6 ?

Solution :

Let the smaller part is x and larger part is y.

39 is separate into two parts x and y

i.e. ....(1)

4 times the smaller exceeds the larger number 6

i.e.   ....(2)

Solving (1) and (2) by adding both equations,

Substitute the value of x in equation (1),

The smaller part is 9 and the larger part is 30.

39 is separated into two parts 9 and 30.

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
