We have three different figures here: A square, a triangle, and a quarter of a circle.

Square:

A = base x height or length x width

A = 8 x 8

A = 64 m^2

Triangle:

A = 1/2 x b x h

A = 1/2 x 8 x 8

A = 1/2 x 64

A = 32 m^2

Quarter circle:

A = pi x r^2

A = 3.14 x 8^2

A = 3.14 x 64

A = 200.96 / 4

A = 50.24 m^2

Area of the composite figure:

A = 64 + 32 + 50.24

A = 146.24 m^2

Hope this helps!! :)

180 ÷ 2 = 90 / The train travels 90 mph....

90 * 7 = 630 / The jet travels 630 mph....

630 * 5 = 3150 / The jet will travel 3150 miles in 5 hours, I hope this helps!

supplementary angles are two angles that add up to 180 degrees, so essentially two angles that, combined, are equal to a straight line.

vertical angles are angles that are opposite each other when two lines cross.

To solve the system of equations below, Pedro isolated the variable y in the first equation and then substituted it into the sec
Reil [10]

Answer:

Resulting equation will be 5x²=36.

Step-by-step explanation:

The given equations are 5y = 10x-----(1)

and x²+y²=36------(2)

Now we substitute the value of y from equation (1) into equation (2).

5y = 10x ⇒ y = 2x

Then equation (2) will be x²+(2x)²=36

x²+4x²=36 ⇒ 5x² = 36

So the equation after substitution of the value of y from equation 1 will be 5x² = 36.
