The correct answer is 30%. Any percentage number out of 100 is the original number. If you're having trouble remembering this, just set up a proportion like you would for any other percentage problem.

30 / 100 = x / 100   In this proportion, we're trying to find the percent out of 100 that 30 divided into 100 is. This is represented by the variable x.
3000 = 100x   Cross-multiply 30 and 100.
30 = x   Divide.

So, x, the percentage that 30 divided into 100 is out of 100, is 30, meaning that 30 is 30% of 100.

Hope this helps!

Soloha48 [4]

Answer:

The answer to your question is the letter A. 904.32 in³

Step-by-step explanation:

Data

radius = 6 in

Volume = ?

π = 3.1416

Formula

Volume = 4/3 πr³

-Substitution

Volume = 4/3 (3.1416)(6)³

-Simplification

Volume = 4/3 (3.1416)(216)

Volume = 2714.342 / 3

-Result

Volume = 904.7 in³

The closest answer to my result is A.904.3 in³

Please explain how to solve for x in the attached photo.
natulia [17]

Answer:

x = 24°

Step-by-step explanation:

the sum of the interior angles in a triangle = 180°

so:

(2x + 5°) + 64° + 3x - 9° = 180°

combine like terms:

5x + 60° = 180°

subtract 60° from each side of the equation:

5x = 120°

x = 24°

Solve -1/8y ≤ 34. then graph the solution.
motikmotik

Answer:

Multiply each term in −1/8y≤34 by −8. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

−1/8y x −8 ≥ 34 x −8 Simplify −1/8y x −8

y ≥ 34 x −8

Multiply 34 by −8.

y≥−272
