Volume of a sphere = (4/3) (pi) (radius)³
The sphere's volume is proportional to the cube of its radius,
so the radius is proportional to the cube-root of the volume.
The only way to double a sphere's volume is to increase
its radius by the factor of
∛2 = 1.26 (rounded).
If it's linear, it will follow the format:
y = mx + b
m is the slope, and b is the y intercept.
Answer:
Width = 18 inches
Perimeter = 99 inches
Area = 567 square inches
Step-by-step explanation:
The sides of a rectangle are in the ratio 4:7. Then
Width
in
Length
in.
If its longer side is 31.5 in, then
Length = 31.5 in
and

So,
Width 
The perimeter is

The area is

Answer:
15) x = 20
16) y = 45°, z = 30°
17) all 4 corners = 90°, all 4 sides are equal length, diagonals are perpendicular, diagonals bisect the corner angles.
We can't do the extra credit because we do not have a relationship about the side lengths. We just have angle information.
Step-by-step explanation:
15) 2x + 8 = 3x - 12
x = 20
16) 2y = 90°
y = 45°
3z = 90°
z = 30°
