Answer:
Volume of a right prism = 65 cubic inches
Its height is increased by a factor of 20.
To find:
The new volume of the prism if the other dimensions do not change.
Solution:
The volume of a prism is:

Where, B is the base area and h is the height.
A right prism has a volume of 65 cubic inches.

The height of prism is increased by a factor of 20. So, the new volume is:




The volume of the new prism is 1300 in³.
Therefore, the correct option is B.
Answer:
x≥ -4/55, x≤−89
Step-by-step explanation:
Step 1: Subtract 1 from both sides.
−110x+1−1≤9−1
−110x≤8
Step 2: Divide both sides by -110.
−110x/-110≤8/-110
x≥ -4/55
Should be letter C to question
1 cleaning crew = 5 offices in 6 hours
You want to find out the number of offices they can clean in 12 hours
6 (hours) is

of 12 (hours)
The opposite of

is 2
6 (hours) multiplied by 2 (opposite of

) is equal to
12
6 x 2 = 12, 12 = the number of offices you're trying to find.
Therefore, you need to multiple 5 by 2 (number that is double), so
5 x 2 = 10
The crew can clean 10 offices in 12 hours
