Answer:
Answer
Find out the how many minutes are spent preparing.
To proof
As given
A recipe takes 90 minutes to make.
25 percent of the time is spent preparing the ingredients.
25% is written in the decimal form
= 0.25
Time spent in preparing = 0.25 × 90
= 22.5 minutes
Therefore the 22.5 minutes are spent preparing the ingredients.
Hence proved
Step-by-step explanation:
Negative 12 over negative 6.
Over means to divide (fraction).
-12/-6
A negative divided by a negative equals a positive.
-12/-6 = 2
Answer: 2
Answer is c. you subtract 4 to both sides and get 3x=21 and then divide 3 to both sides to get x=7
Answer:
b + 9
Step-by-step explanation:
Given:
(b + 3) + 6
Required:
Rewrite expression without the parentheses.
SOLUTION:
(b + 3) + 6
Eliminate the parentheses
b + 3 + 6
Add like terms
b + 9
Thus:
(b + 3) + 6 = b + 9
Formula:
V = 1/3 * pi * r^2 * h
Plug in what we know:
V = 1/3 * 3.14 * 3^2 * 4
V = 37.68cm^3
So the volume is 37.68cm^3 which rounds to 37.7cm^3.
