2 2/3 x 3 = 8/3 x 3

8/3 x 3 = 8

First convert the mixed number to an improper fraction which will give you

There are 7 gallons of black paint available to motorola. If 5/9 gallons is used each run, How many runs can we paint?

nadya68 [22]

There are 7 gallons of black paint available to motorola. If 5/9 gallons is used each run. To find the amount of runs you can paint, you have to divide the total by the amount for each run.

$7 \div \frac{5}{9}$

When dividing fractions, you have to keep, change, and flip.

$Keep\ 7 \\ Change\ \div\ to\ \times \\ Flip \frac{5}{9} = \frac{9}{5}$

Your new equation is:

$7 \times \frac{9}{5}$

Multiply:

$7 \times \frac{9}{5} = \frac{63}{5} = 12 \frac{3}{5}$

You can paint $12 \frac{3}{5}$ or $12.6$ runs.

Find the sum of the geometric series for which a = 160, r = 0.5, and n = 6.

harina [27]

$\\ \sf\longmapsto S_n=\dfrac{a(1-r^n)}{1-r}$

$\\ \sf\longmapsto S_n=\dfrac{160(1-0.5^6)}{1-0.5}$

$\\ \sf\longmapsto S_n=\dfrac{160(1-0.015625)}{0.5}$

$\\ \sf\longmapsto S_n=\dfrac{160(0.984378)}{0.5}$

$\\ \sf\longmapsto S_n=80(0.984378)$

$\\ \sf\longmapsto S_n=78.75$

If f(x)=5x and g(x)=2x-1, what is the composition f(g(x))?

Paul [167]

Answer:

10x-5

Step-by-step explanation:

f(x)=5x

g(x)=2x-1

To create a composite function, replace x in f(x) with g(x)

f(g(x)) = 5(g(x) = 5(2x-1) = 10x-5
