Express 75° in radians. Round to the nearest hundredth.

1 answer:

7 0

Hello!

To convert degrees to radians you multiply it by $\frac{ \pi }{180}$ . We will do so below.

75( $\frac{ \pi }{180}$ )≈1.31

Therefore, the correct answer is A.1.31 radians.

I hope this helps!

Find the percent of increase to the nearest whole from 12 to 20

ankoles [38]

Answer:

The answer is

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
