Jack is 4 times as old as Lacy. 4 years ago the sum of their ages was 52. How old are they now

Papessa [141]

Answer:

Jack = 48 years old , Lac = 12 years old

Step-by-step explanation:

Jack = 4Lacy

(Jack - 4) + (Lacy - 4) = 52

Now, substitute.

4Lacy - 4 + Lacy - 4 = 52

5Lacy = 60

Lacy = 60/5 = 12

Jack =4Lacy

=4(12)

=48

What is the height of the can?

Yuliya22 [10]

Answer: The height is 5 inches.

Step-by-step explanation:

The surface area of a cylinder uses the formula A= 2 $\pi$ rh + 2 $\pi$ r^2

so as you could see in the equation there is an h in in it which re

presents the height and we know the diameter is 2 so we need to find the radius and the radius is 1 because half of 2 is 1 or half the diameter is the radius.

Now put the radius into the equation and and solve for the height and as you could see the surface area is left in terms of pi.

12 $\pi$ = 2 $\pi$ * 1 * h + 2 $\pi$ * 1

12 $\pi$ = 2 $\pi$ * h + 2 $\pi$

-2 $\pi$ 2 $\pi$

10 $\pi$ = 2 $\pi$ h

h =5
