Answer:
This means that the cost of 2 heating oil gallons is 14.
Step-by-step explanation:
f(x) = 4x + 6 , where x is the number of heating oil gallons.
And f(x) = 4x + 6 is the equation for the cost of x gallons.
When the number of gallons are 2 then the cost is;
f(2) = 4(2) + 6 = 8 + 6 = 14
This means that the cost of 2 heating oil gallons is 14.
Answer:
No
Step-by-step explanation:
For x and y to have a proportional relationship, then
the ratio of k =
must be equal for all points
(2, 5) → k =
= 2.5
(3, 7.5) → k =
= 2.5
(5, 12.5) → k =
= 2.5
(18, 8) → k =
= 2.25 ≠ 2.5
k is not equal for all values , hence no proportional relationship exists

Answer:
A.77
Step-by-step explanation:
The line makes 180 and one side is 103 so you subtract 103 from 180 to make it equal
The formula for the volume of a cone is 1/3

r²h, where r is the radius and h is the height.
Insert the values into the equation:
1/3

(5)²(11) ≈ 287.979327 (use a calculator for this part)
Divide 287.979327 by

and convert the decimal to a fraction:
91.66666666666666666666666666666666666666... = 91 2/3
The volume of the figure is 91 2/3

cubic units or units³.
