Answer:
Instead of wasting hours of your life doing that, just use Desmos (website)
Step-by-step explanation:
X=100 because 20 X 5 is 100
So, first let's refill the barrel to the top:
37.5 + 7*2.5 = 55
Now that it's full again, let's divide the total amount by the rate of water loss:
55/2.5 = 22
It will take 22 minutes to completely empty the rain barrel
It kind of looks like your missing something in you problem. But if f(x) = 3 is correct, then it doesn't matter what x is the answer is always going to be 3. So f(4.5) = 3. Most of the time though f(x) means a function of x, so there is an x in the problem. For example: f(x) = 3x, then f(4.5) = 3*4.5 = 13.5.
Answer:
615.44 cm^2
Step-by-step explanation:
here r, radius is 14 cm and π as 3.14
area of circle = π
3.14 * 14^2
3.14 * 14 * 14
615.44cm^2
