Answer:

x = 35

Step-by-step explanation:

First count how many interior angles we have here.

There are 6 interior angles.

so we then can determine the interior sum of the angles here.

Inside angle sum = 180*(6 - 2) degrees = 180*4 = 720 degrees

(4x - 5)+(4x - 3) + 118 +(3x+6) + (3x-3) + 117 = 720 degrees

8x - 8 + 118 + 6x + 3 + 117 = 720 degrees

14x -8 + 118 + 120 = 720 degrees

14x + 230 = 720

14x = 720 - 230

14x = 490

x = 35

Lucas lives 5/8 mile from school Kenny lives twice as far from school how many miles does Kenny from school

Tresset [83]

To figure this out we simply add 5/8 + 5/8. 5/8 + 5/8 = 1 1/4. So Kenny lives 1 1/4 miles away from school.

I hope this helps!

A model airplane is built to a scale of 1 in.:12 ft. If the model plane is 11 inches long, find the length of the actual plane,

torisob [31]

Answer:

132 feet

Step-by-step explanation:

we know that

The scale is equal to $\frac{1}{12}\ \frac{in}{ft}$

That means ---> 1 inch in the model represent 12 feet in the actual

To find the actual dimensions of the airplane, divide the dimensions of the model by the scale

$11\ in:\frac{1}{12}\ \frac{in}{ft}=11(12)=132\ ft$

A large washer has an outer radius of 10mm and a hole with a diameter of 14mm. What is the area of the top surface of the washer

choli [55]

<h2>Answer:</h2>

The area of the top surface of the washer is: 160.14 square mm.

<h2>Step-by-step explanation:</h2>

The top of the surface is in the shape of a annulus with a outer radius of 10 mm and a inner radius of 7 mm ( since the diameter of the hole is: 14 mm and we know that the radius is half of the diameter)

Now, we know that the area of the annulus region is given by:

$Area=\pi (R^2-r^2)$

where R is the outer radius and r is the inner radius.

Here we have:

$R=10\ mm\\\\and\\\\r=7\ mm$

Hence, we have:

$Area\ of\ top\ surface=\pi (10^2-7^2)\\\\i.e.\\\\Area\ of\ top\ surface=\pi (100-49)\\\\i.e.\\\\Area\ of\ top\ surface=\pi\cdot 51\\\\i.e.\\\\Area\ of\ top\ surface=160.14\ mm^2$
