Answer:
12 correct answers
Step-by-step explanation:
Since in the main part she scores 8.3 points for each question she answers correctly, we can assume that the number of questions she answers correctly=a
Therefor, the total number of points she achieved in the math test in the main part alone can be expressed as:
Total score(main part)=8.3×a=8.3a points
She also solved a bonus question worth=11 points
Consider expression 1 below
The total score in the whole test=Total score in the main part+Bonus points, where;
Total score in the whole test=110.6 points
Total score in the main part=8.3a points
Bonus points=11 points
Substituting the values in expression 1:
8.3a+11=110.6
8.3a=110.6-11
8.3a/8.3=99.6/8.3
a=12
Number of correct answers in the main part=a=12

Answer:
D = 35.8 degrees
Step-by-step explanation:
In this question, we are asked to use calculator to estimate the approximate measure of angle D given its tan value.
From the question, what we have is;
tan D = 0.72
Now to calculate the acute angle D, we will divide through by tan
hence,
D = tan^-1 0.72
or more simply tan^-1 can be called arc tan
Thus, D = arc tan 0.72
D = 35.75
D = 35.8 to the nearest tenth of a degree
