5. find the area of an equilateral triangle with radius 8 m. leave your answer in simplest radical form.

The area of an equilateral triangle is .

Step-by-step explanation:

Given: The radius of an equilateral triangle is 8m.

To find: The area of an equilateral triangle.

Solution: It is given that the radius of an equilateral triangle is 8m.

Now, height of the triangle is given as:

Substituting the value of r, we have

The side of the triangle is given as:

Now, the area of an equilateral triangle is given as:

Therefore, the area of an equilateral triangle is .

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
