Answer:
A
Step-by-step explanation:
Area = length times height times width
Area = 164 x 82 x 9.8
= 131790.4
Multiply by 7.48 since it takes 7.48 gallons to fill a cubic foot then you find the answer of A.
Answer:
5 and 6
Step-by-step explanation:
You have to find two numbers (in the chart) that have a difference of 3/8.
This is just one possiblity, there are other correct answers.
There is size 5 and 6. 9 and 4/8-9 and 1/8=3/8.
First you need to find the y-intercept, which is y = -1
Next is we need to find the slope of the line > you are going to have to do this by finding to clear point
The ones that I will be using are: (3, 1); (6, 3) (You could take any points)
Now using the slope formula we could find m.
m = y2-y1 / x2-x1
(1 - 3) / (3 - 6) = m
-2 / -3 = m
m = 2/3
Using the linear function format: y = mx + b
Therefore the equation of the line is y = 2x/3 -1
23 is the number the answer is c
