Jan typically earns $575 per week. she has $172.50 withheld from her paycheck each week. what percent is being withheld from her paycheck? type your answer as a percentage using the % symbol.

30%

Step-by-step explanation:

What your problem is asking basically is how many percent is the withholding of her earnings each week. We just divide what is withheld by the earnings.

Because we need it in percentage, we then multiply it by 100%.

0.30 x 100% = 30%

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

answer: the answer is   graph (a)
