Mitchell took a math exam today. if he got 63 out of 84 questions correct, what percentage did mitchell get wrong? (answer using a percent sign

75%

Step-by-step explanation:

If Mitchell took a math exam and got 63 out of 84 questions correct, that would turn into the fraction: 63/84

In order to convert this to a decimal, you divide 84 by 63 (since every fraction is a division problem), and get 0.75.

When you change decimals into percents, you move the decimal point two times to the right. So, that would be 75.

Then you add the percent symbol and you're done!

I hope that helped :)

n = 75

Mitchell got 75% right. Thus,

100% - 75% = 25% wrong

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
