Answer:
Step-by-step explanation:
The wording, "the quotient of a number and 4," can be displayed as c/4. C would be our variable for the number because the question asks specifically for it. 5 more would demonstrate that we're adding 5 more to our equation. Which would result in c/4 + 5. However, since it equals 7, just add that portion to create the following equation:
Answer: 27%

Answer:
9.54
Step-by-step explanation:
29.04/2.4 = 12.1
12.1-2.56 = 9.54
Answer:
1/6^4.
Step-by-step explanation:
Multiply denominators.
6*6*6*6 = 1,296
Your answers are 1/6^4 and 1/1296.
To solve this problem we will start by calculating time needed for each of them to fill the pool.
We have formula:
Volume = rate * time
Or
time = volume / rate
Wilma:
time = 9900 / 900
time = 11h
Betty:
time = 9900 / 500
time = 19.8h
Now we substract these two numbers:
time_difference = 19.8 - 11 = 8.8h
Betty needs 8.8 hours more than Wilma to fill the pool.
