Answer:
42.22 (2 repeating)
Step-by-step explanation:
When you are given percentage problems, you deal with the percent (%), base (amount you are starting with), and the amount.
Starting with the most basic equation,
Percent * Base = Amount
In this problem, you are given the amount (38) and the percent (90)
So to find the base, you can do
Base = Amount / Percent
As always, convert the percent to a decimal by dividing by 100.
38/ 0.9 = 42.222 repeating
Answer:
A
Step-by-step explanation:
it includes all the combinations.
Solve for x
-53 + 8x = 3x + 47
8x - 3x = 47 + 53
5x = 100
x = 20
If sin(90°) = 1, then cos(90°-90°) = cos(0°) = 1
Less than or equal too it is the second one
