Find the area of the shaded regions:
Crank

First, we'll find the area of the large section, including the smaller section that is white.

Area of a circle: pi x r^2

A = pi x 7^2

A = 49pi x 120/360

A = 49/3 pi cm^2

Now, we'll find the area of the small section.

A = pi x 3^2

A = 9 pi x 120/360

A = 3pi cm^2

All that's left to do now is subtract.

49/3 pi - 3 pi

40/3 pi cm^2

(or 13 1/3 = 13.33 cm^2)

Hope this helps!

PLZ HELP!!!!!! What is 1-34 divided by (3x8-7) - 2x3
serious [3.7K]
You do the brackets first so 3x8 = 24 - 7 = 17

You then do divide so 34/17 = 2

You then do the multiplication so 2x3= 6

Then you have 1-2-6 = - 7

The order you do it in is BIDMAS
B = brackets
I = indices
D = division
M = multiplication
A = addition
S = subtraction

So the answer is - 7

  • Addition Property of Equality

<u>Algebra I</u>

  • Terms/Coefficients
  • Coordinates (x, y)
  • Solving systems of equations by substitution/elimination

Step-by-step explanation:

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

y = 5x

20x - 4y = 0

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

<em>Substitution</em>

  1. Substitute in <em>y</em> [2nd Equation]:                                                                        20x - 4(5x) = 0
  2. Multiply:                                                                                                             20x - 20x = 0
  3. Combine like terms:                                                                                         0 = 0

Here we see 0 does indeed equal 0.

∴ our systems has an infinite amount of solutions.
