1. 6 \pi
This is because 
c=  \pi d \\ 
c= 6 \pi

2. 9 \pi
because 
A= \pi  r^{2}  \\ 
A =  \pi (3)^{2}  \\ 
A = 9 \pi

3. 4 \pi
C=  \pi d \\ 
C= 4 \pi

4. 4 \pi
A = \pi r^{2} \\ A = \pi (2)^{2} \\ A = 4 \pi

Can't really answer the last 2 w/o the figures

Find the solution set for 8x - 3 = 2(x - 1/2)​
KiRa [710]

Answer:

x = 1/3

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

8x - 3 = 2(x - 1/2)

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distributive 2:                              8x - 3 = 2x - 1
  2. Subtract 2x on both sides:         6x - 3 = -1
  3. Add 3 to both sides:                   6x = 2
  4. Divide 6 on both sides:              x = 1/3

Determine the length of the hypotenuse of a right triangle if the legs have lengths 12 inches and 16 inches?
tiny-mole [99]

Answer:

c = 20 inches

Step-by-step explanation:

To find the sides of a right triangle, you use the Pythagorean Theorem.

a² + b² = c²

You know a and b, and you need to find c, the hypotenuse.

Plug in a and b.

(12)² + (16)² = c²

Simplify by solving the exponents.

144 + 256 = c²

Combine the constants.

400 = c²

Take the square root of both sides.

√400 = √c²

Solve the √

±20 = c

The length cannot be negative, so you can eliminate that as an option.

So, c = 20
