sergiy2304 [10]

Answer:

16

Step-by-step explanation:

a = age

  1. \frac{a}{4}  + 6 =  \frac{a}{8}  + 8
  2. you will multiply by 8 now
  3. 2a + 48 = a + 64
  4. now move a's with a's and the numbers that don't have a variable with each other
  5. 2a - a = 64 - 48
  6. now subtract
  7. a = 16
  8. I hope it helps you!

How many circles with a 3ft radius could fill a 100 square foot (10ft x 10ft) space without overlap?
Alborosie

Answer:

1

Step-by-step explanation:

Considering that the circle has radius of 3ft to mean its diameter is twice the radius hence 6 ft

Given that the length of the square is 10 ft

10÷6=1 ⅔ hence only 1 circle

10-6=4 ft

The space of 4ft can't allow another circle to fit without an overlap. Therefore, only one circle can fit
