Find the percent of increase to the nearest whole from 12 to 20
ankoles [38]

Answer:

The answer is

<h2>67\%</h2>

Step-by-step explanation:

To find the percentage increase we use the formula

<h3>Percentage \:   change =  \frac{change}{original \:  \: quantity}  \times 100\%</h3>

From the question

The original value = 12

To find the change we subtract the smaller value from the larger one

That's

Change = 20 - 12 = 8

So the percentage increase is

<h3>\frac{8}{12}  \times 100 \%\\  =  \frac{2}{3}  \times 100\% \\  = 66.67\%</h3>

We have the final answer as

67\% to the nearest whole number

Hope this helps you

Find the measure of the missing side. Round
stich3 [128]
Given x = hypothenuse
10.8 = opposite
Degree = 57
You can use Sine (O/H)
Sin(57) = 10.8/x
0.8386705679 = 10.8/x
10.8 = 0.8386705679x
x = 10.8/0.836705679
x = 12.90776467 (round to tenth)

Solution: x = 12.9
