A student earned a grade of 80% on a math test that had 20 problems. How many problems on this test did the student answer correctly? (round to the nearest whole number)

16 problems.

Step-by-step explanation:

100% divided by 20 questions.

100/20 is equal to 5, therefore each question is worth 5 points.

Grade of 80% divided by points per question.

80/5 is 16 so the student answered 16 questions correctly.

The equation is; A student got a grade of 80% on a test that has 20 problems.

1/20 = 5%

2/20 = 10%

3/20 = 15%

4/20 = 20%

5/20 = 25%

6/20 = 30%

7/20 = 35%

8/20 = 40%

9/20 = 45%

10/20 = 50%

11/20 = 55%

12/20 = 60%

13/20 = 65%

14/20 = 70%

15/20 = 75%

16/20 = 80%

As your final answer, as shown above, 16 is your final answer!

∠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°
