Answer:
48 Cubic Inches
Step-by-step explanation:
One foot, whether it be squared, cubed, or otherwise changed, will always equal twelve inches to the same power. So, 4 cubic feet is 48 cubic inches because 4*12=48
There is many ways to do this but i did it this way.
180-123.75= 56.25

=11.25
Answer:
8.8 cm
Step-by-step explanation:
-We know that the top 20% of the books are oversized.
-We therefore find the z-value of the top 20%:

#We substitute the z value in formula to solve X.

Where
- X is the minimum thickness of the book.
-Given
, the minimum thickness,X can be calculated as follows:

Hence, the minimum thickness of the oversized books is 8.8 cm

Answer: x = 11
To start, we know that a whole circle equals 360 degrees. If we subtract the 2 arcs we know, 85 and 31, we have 244 degrees left for the 2 congruent arcs. Dividing that by 2 gives us 122 for each arc.
Now, write the equation: 122 = 13x - 21
Solve this, to find the x = 11.
