Answer:

Area of given figure = 37.68 unit²

Step-by-step explanation:

Given:

Radius of given shape = 4 unit

Angle = 270°

Value of π = 3.14

Find:

Area of given figure

Computation:

Area of given figure = [Ф/360][πr²]

Area of given figure = [270/360][(3.14)(4)²]

Area of given figure = [0.75][(3.14)16]

Area of given figure = [0.75][50.24]

Area of given figure = 37.68 unit²

Guys please help me
stich3 [128]

Answer: (x + [-1], y + [1])

Step-by-step explanation:

      <em>See attached. </em>We can draw, or picture it in our heads, what the reflection would look like. Then we can pick one (or multiple to test) points and see the translation.

      We can also test with a set of points. B', (2, 4) becomes G in the transformation. G is at (1, 5)

      (1 - 2, 5 - 4) -> (-1, 1)

What is the solution to the equation 6n+7=55
weeeeeb [17]

Answer:

n = 8

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>

6n + 7 = 55

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

  1. Subtract 7 on both sides:                    6n = 48
  2. Divide 6 on both sides:                       n = 8

<u>Step 3: Check</u>

<em>Plug in n into the original equation to verify it's a solution.</em>

  1. Substitute in <em>n</em>:                    6(8) + 7 = 55
  2. Multiply:                               48 + 7 = 55
  3. Add:                                     55 = 55

Here we see that 55 does indeed equal 55.

∴ n = 8 is a solution of the equation.
