Answer:

9(6+5x)

Step-by-step explanation:

54 + 45x-------- (Write out the original equation in standard form. This has already been done.)

=9(6) + 9(5x) -------- (For this step, you rewrite 54 as 9(6) and 45 as 9(5).

=9(6+5x)--------- (For this step, you factor out 9 because it is the greatest common denominator.)

Answer:

$\frac{8}{20}$

Step-by-step explanation:

We have been given that in the after school Dena, Shawn, and Amanda knit scarfs that are the same size with yellow, white, and blue yarn. Denas scarf is 2/5 yellow, Shawn's scarf is 3/5 , and Amanda's scarf is 3/4 yellow.

To make Amanda's argument true, let us compare each fraction by making a common denominator.

We can see that least common denominator of each fraction would be 20.

$\text{Dena's scarf}=\frac{2}{5}\Rightarrow\frac{2*4}{5*4}=\frac{8}{20}$

$\text{Shawn's scarf}=\frac{3}{5}\Rightarrow\frac{3*4}{5*4}=\frac{12}{20}$

$\text{Amanda's scarf}=\frac{3}{4}\Rightarrow\frac{3*5}{4*5}=\frac{15}{20}$

Since $\frac{8}{20}$ , therefore, Amanda's scarf has the most yellow.

Your class build a teepee has a diameter of 16 ft and a height of 13.5 ft. what is the volume? use 3.14 for pi. round your answe

bearhunter [10]

Cone Volume = (π • r² • h) ÷ 3

Cone Volume = (PI * 8^2 * 13.5) / 3

Cone Volume = (3.14 * 64 * 13.5) / 3

Cone Volume = 2,712.96 / 3

Cone Volume = 904.32 cubic feet

Cone Volume = 904 cubic feet (rounded)
