That's the answer in my opinion.good luck!
Answer:
2.83 inches
Step-by-step explanation:
The formula for surface area of cube = 6s²
Where
s = side length of cube
S.A = 6s²
s² = S.A/6
s = √S.A /6
For cube a
Surface area = 1200 in²
Hence,
side length = √1200/6
Side length = √200
= 14.14 inches
For cube b
Surface area = 768 in²
Hence,
side length = √768/6
Side length = √128
= 11.13 inches
How much longer is the side of a cube with a surface area of 1,200 square inches than a cube with the surface area of 768 square inches?
Therefore,
14.14 inches - 11.13 inches
= 2.83 inches
Find the amount of the increase:
27800 - 23400 = 4,400
Find number of years: 2012 - 2008 = 4 years
Divide amount of change by number of years:
4,400 / 4 = 1,100 people per year.
Answer:
y = x - 12
Step-by-step explanation:
Since the lines are parallel, the slopes are the same.
The desired equation has the form y = x + 1. Replacing the constant (1) by C, we get y = x + C. Finally, we substitute 12 for x and 0 for y in y = x + C to determine the value of C:
0 = 12 + C, or C = -12
Then the equation of the line is y = x - 12.
