Hello There!

2/3 + 1/3 = ?

                                                        Solving

                                           { Add the numerators }

                                                     2 + 1 = 3

                                  { The denominator stays the same }

                                                         3/3

                                        3/3 also equals 1 whole.


Hope this helped!

Circumference is found with the formula

c = pi × d

d is diameter and we will use 3.14 for pi.

The diameter is the measure across the center of the circle. In the first problem, you are given the radius, so we have to multiply by 2 to get the diameter. Then we can use the formula.

12.4 in × 2 = 24.8 in (that's the diameter)

c = pi × D
c = 3.14 × 24.8
c = 77.872 inches

circumference is 77.872 inches.

Try the other problems on your own. They are just like this one. Just make sure they are giving you the diameter and not the radius. Post if you have problems.

Express the product in simplest form.
Romashka [77]
\frac{8}{2x+8} *  \frac{ x^{2}-16 }{4}

1. Cross cancel
\frac{4}{2x+8}* \frac{ x^{2} -16}{1}

2. Multiply numerators
4*x²-16 = 4x²-64

3. Multiply denominators
2x+8*1 = 2x+8

\frac{4 x^{2} -64}{2x+8}

4. Divide
\frac{4 x^{2} -64}{2x+8} = 2x-8

5. Simplify
2(x-4)

Answer is 2(x - 4)

Answer:

a= 20

b= 169.7

c= 29.71

Step-by-step explanation:

The formula of a triangle is (h*b)/2

a= (5*8)/2

b= to find the height, you can use the pythagorean theorem 18^2 - 6^2 = square root of 288. Which is 12root 2 or 16.97. (16.97*20)/2

c= using the pythagorean theorem- 11^2 = 7^2 - c^2 = square root 73, or 6root 2, or 8.49. (8.49* 7)/2
