Answer:

x = 120

Step-by-step explanation:

Express the ratios as equivalent fractions, that is

\frac{x-20}{x+280} = \frac{1}{4} ( cross- multiply )

4(x - 20) = x + 280

4x - 80 = x + 280 ( subtract x from both sides )

3x - 80 = 280 ( add 80 to both sides )

3x = 360 ( divide both sides by 3 )

x = 120

What is the simplified form of the expression -2(-5x - 8)?
Deffense [45]

Answer: 10x+16

Step-by-step explanation:

Use the distributive property a(b+c)= ab+ac

so

-2(-5x-8) = (-2 * -5x) - (-2* -8)

=

10x-(-16)

=10x+16

Hope this helped!

pleeeeeeeeeeeease hellllllllp meeeeeee the circle has a center of 0.its raduis is 3 cm,and the central angle A measures 100.what
Vsevolod [243]

Answer:

2.5 pi

Step-by-step explanation:

Comment

If you were trying to get the area of a whole circle, you would use

Area = pi r^2

You have to modify the formula to show that just part of the circle has an area that you are interested in.

The new formula is

Area = (theta/360) pi r^2

Givens

r = 30 cm

theta = 100

Solution

Area = (100 / 360) * pi * r^2       Substitute the givens into this formula

Area = (5 / 18) * pi * 3^2              Expand

Area = (5 / 18) * pi * 9                  Cancel 9 into 18

Area = 5/2 * pi

Area = 2.5 * pi
