The equation (1•2)^72 (72 20 minute periods in a day) would produce way more than 5 billion a day
Answer:
Step-by-step explanation:
The shaded area is the difference of the large and small squares.
<u>Area of large square:</u>
<u>Area of small square:</u>
<u>Shaded area:</u>
- A = A(l) - A(s)
- A = (y + 4)² - y² = y² + 8y + 16 - y² = 8y + 16
So 1/4
that measn that the scale wall is 6 inches while the real wall is 4 times 6=24 inches tall (logically, it would be something like 1in/4ft so it woul dbe 24 feet not 24 inches but ok)
so 1/4
6 inches scale drawing is 1/4 of real wall
6=1/4 real
multiply by 4
24=real
asnwer is 24 inches
