The formula s = StartRoot StartFraction S A Over 6 EndFraction EndRoot gives the length of the side, s, of a cube with a surface
jeyben [28]

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

A line passes through the point (12,0) and is parallel to the line with the equation y = x + 1. What's the equation of the line?
Alborosie

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.
