Answer:
Step-by-step explanation:
3*7*10*10*10*10*10*10*10
(5+2=7)(since is multiplication you add)
21*
=B
<u>2*10*10*10*10*10</u>
4*10*10
(5-2=3)(since is division you subtract)
0.5*
=c
Exponents can make the problem smaller and look less confusing. If you see a problem with 5*5*5*5*5*5*5*5 then you're going to eventually loose count and will have to keep repeating. But if you put 5 to the 8th power then you know right away just to multiply 5, (8) times,
Composite number is made up of 2 or more prime numbers
a prime number is only made up of itself and 1
composite and prime numbers are like oposites
a prime is not a composite but it is a prime number
confusing quesiton
Answer:
83%
Step-by-step explanation:
We can put this into a fraction to get the ratio of the new price over the old price

This will give us the percentage of how much was decreased.
The answer you get is .83
Bring 2 decimal places to the right to get 83 (converting from decimal to percentage)
You get 83 percent to be your answer
