4. "Ten less than the quotient of a number and<br>3 is 8."​
Nookie1986 [14]

Answer:

3x - 10 = 8

Step-by-step explanation:

Let's reconsider the wording of this problem.

"Ten less than the quotient of a number and

3 is 8."​

From less, we can assume 10 is being subtracted from something.

We have:

-10

Next, we know that the quotient is the sum of a multiplication problem. So, we know 3 has to be multiplied by something. We can see that the text says 'a number'. If they don't give us the value we can guess that it is the variable x.

Now:

3x - 10

From 'is 8' we know that must be the final sum of the equation.

Finally:

3x - 10 = 8

A regular hexagon has a radius of 20in. What is the approximate area of the hexagon
Wittaler [7]

Answer:

A= 1038 in²....

Step-by-step explanation:

There are several ways to find the area of a regular hexagon

In a regular hexagon, split the figure into triangles.

Find the area of one triangle.

Multiply this value by six.

We will apply the formula of area of regular polygon:

A= 1/2r²nsin(360/n)

r = radius

n = number of sides of the regular polygon

We know that,

r= 20 in

n= 6

Now substitute the values in the formula:

A= 1/2(20)²(6)sin(360/6)

A= (20)²(3)sin(360/6)

A= (20)²(3)sin(60)

A=3*(20)² *√3/2

A= 1200 * √3/2

A= 600*√3

A= 1038 in²....

Therefore the approximate area of hexagon is 1038 in²....
