42.5% of what = 20.57
<span>42.5% of x = 20.57
</span>
(42.5/100)*x = 20.57
42.5x / 100 = 20.57
x = 20.57 * 100 / 42.5
x = 48.4
Therefore 42.5% of 48.4 is 20.57.
Answer:
(f + g)(x) = 3x² + x + 5
(f - g)(x) = 3x² - x - 3
Step-by-step explanation:
(f + g)(x) → f(x) + g(x) → <u>3x² + 1</u> + <u>x + 4</u>
Combine like terms and you get: 3x² + x + 5
(f - g)(x) → f(x) - g(x) → <u>3x² + 1</u> - (<u>x + 4</u>)
Remember to distribute the neg. everything in the parentheses. Combine like terms and you get: 3x² - x - 3
Answer:
48x
PEMDAS: Do the exponent first 4 times 4 is 16 times that by 3x to get 48x.
Answer:
7 hours and 15 minutes
Step-by-step explanation:
8:15 to 3:15 is 7 hrs then just add the remaining 15 minutes to get to 3:30.
sinФ = 1/6
sinФ = opposite/hypotenuse
cosФ = adjacent/hypotenuse
tanФ = opposite/adjacent
SOHCAHTOA
1^(2)+b^(2)=6^(2)
1+b^(2)=36
b^(2)=35

cosФ =
/6
tanФ = 1/
=
/35
