If sally got 28 questions correct and received 70% on the exam, how many questions were on the exam
Furkat [3]

Answer: 40

Step-by-step explanation:

Number of correct questions Sally got = 28 questions

Percentage of correct questions answered= 70% on the exam,

Total number of questions in the exam = Unknown

Let the total questions in the exam be represented as y.

Since Sally got 70% correctly, this will be:

70% of y = 28

70/100 × y = 28

0.7 × y = 28

0.7y = 28

Divide both side by 0.7

0.7y/0.7 = 28/0.7

y = 40

There are 40 questions in the exam.

C. Tan k=31/24<br> D. Cos k= 31/24
lubasha [3.4K]

Hello!

The sin of D would be the opposite side divided by the hypotenuse. As we have no hypotenuse length, neither A or D would work, as the cosine also involves the hypotenuse.

The tangent is the opposite divided by the adjacent. This would be, in terms of D, 24/31. This does not match our option.

In terms of K, the tangent is 31/24.

Therefore, our answer is C) tanK= 31/24

I hope this helps!
