Answer:
16 minutes
Step-by-step explanation:
If it takes 63 minutes to paint 9 walls then it means for every wall, it takes 63/9=7 minutes
Since it is 4 people working for 7 mins, the individual rate is 4/7 minutes per person
When we have 7 people, then the number minutes they take will be 7*4/7=4 minutes per wall
4 min per wall for 4 walls then total time will be 4*4=16 minutes
Answer:
I think it's the first one
Step-by-step explanation:
Hi there!
First of all we need to remember the number 6.32.
It could be any of the following:
6.323 OR 6.324
We are rounding UPPP! If you were to round down it would be 6.32 or less.
Hope this helped!
An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
Answer:
We subtract exponents when diving powers with the same base because they eventually get canceled out when written in expanded form.
Step-by-step explanation:
For example, if we expand the given fractions:
10^3/10^1 = 1000/10 = 100 = 10^2
Now, if we subtract the exponents we get the same result.
10^3-1 = 10^2
So, a^m/a^n = a^m-
n is one of the exponent rules which saves time and makes calculation easier.
