Answer:
12
Step-by-step explanation:
if you combine the triangles (1/2) you get 6 since they are 0.5 of a unit divide by two = 3 add to 9 =12
we know that
Average Rate of Change. is the change in the y-value divided by the change in the x-value for two distinct points on the graph
So

in this problem

substitute the values in the formula above

Divide by
both numerator and denominator

therefore
the answer is

Answer:
Step-by-step explanation:
<u>Let the capacity of tank is x</u>
- 1/5x + 9 = 7/10x
- 2/10x + 9 = 7/10x
- 5/10x = 9
- 1/2x = 9
- x = 18 gallons
Answer:
V=(πr^2 x h)/3
lets use π as 3.14 cause I dont know what pi u using
3.14 x 4^2 x 15 = 753.6/3 = 251.2
If you're using π as your pi, than just replace 3.14 by π on calculator
Hope that answers your question
