Tom has a jar of quarters and dimes. he has q quarters and d dimes. write an expression that represents the total value in cents of the coins in the jar using the variables q = q=the number of quarters in the jar and d = d=the number of dimes in the jar.

25 p+10 q

Step-by-step explanation:

Given : Tom has a jar of quarters and dimes. he has q quarters and d dimes.

Let q = the number of quarters in the jar and d =the number of dimes in the jar.

We know that 1 quarter =25 cents

And 1 dime =10 cents

Then, Value of p quarters=25p

Value of q dimes=10 q

Thus the total value of the coins ( in cents) = 25p +20 q

Therefore, the expression that represents the total value in cents of the coins in the jar :-

25p+10q

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
