It is irrational.
A = π r^2 = π[3/4 cm]^2 = 9π/16 cm^2
An irrational number (Pi in this case) multiplied by a rational number (9/4) gives an irrational number.
The sum of the rational expression is
X=4
X/3 - 3/4 = 5/2
x/3 = 3.25
x= 9.75 Or 9 3/4
Answer:
15 hours
Step-by-step explanation:
To find the gallons per hour: 230/5=46, this means that it take 46 gallons per hour, you add 46 to 230, and you do that 15 times and you'll get 920. The pool will be filled at 11:00 pm.
8x - 32 = 6 - 9x
17x = 38
x = 38/17
