It would be 16 minutes because you would divide 80 by 20 and you get 4 so now you multiply 4 by 4 and you get 16
Answer:
Step-by-step explanation:
so 20% of the total price equals $ 30
let x represent the total price
turn ur percent to a decimal

x = 30 / 0.20
x = 150 <=== total price
Answer:
17.5 hours
Step-by-step explanation:
107 = 60(2^n)
n(lg2) = lg(107/60)
n = 0.8345763908 × 21
n = 17.52610421 hours
Answer:
AB = 2
BC = 2
A'B' = 6
B'C' = 6
Step-by-step explanation:
Answer: 20
Explanation: Alright, so basically you’re going to want to use PEMDAS (Parenthesis, Exponents, Multiplication/ Division, Addition/ Subtraction)
* just means multiply.. sooo the problem looks like this:
6x(12-7.5)-7
We’ll start at the parentheses :)
So (12-7.5) = 4.5
Now our problem looks like: 6x(4.5)-7
Following PEMDAS, the next thing to come up is multiplication! So we’re going to multiply 6 by 4.5 ...
6x4.5=27
After this our problem looks like: 27-7
So now it’s just simple math...
27-7= 20
