Answer:

The last one

Step-by-step explanation:

42 of the 150 employees at Carlo's Car Repair wear contact lenses. What percent of the employees wear contact lenses?
antiseptic1488 [7]
\frac{42}{150} ÷ 2 = \frac{21}{75}

\frac{21}{75} ÷ 3 = \frac{7}{25}

\frac{42}{150}= \frac{7}{25}

Then, divide 7 by 25 because 25 is the divisor

7 ÷ 25 = 0.28

28% is the answer (:

When θ = 0, sin θ = 0. What is the next radian value that will result in sin θ = 0?
IgorC [24]
If you look at the sine curve,
you'll find the curve passing through x axis,
firat at x=0, and then at x =pi.

hence, after 0, next radian value for which sin x = 0 is x = pi
