Nutka1998 [239]

Answer:

56 problems

Step-by-step explanation:

So we already know that the answer is: 56. However, a good help is knowing how to obtain this answer from the data provided.

Tony's quiz had 80 questions

Tony correctly answered 70% of them.

We can always write a percentage amount as a ratio by dividing the amount by 100.

$70\% = \frac{70}{100} = 0.7$ .

This means that for every 100 questions, tony will respond correctly 70.

So, if Toni did a questionnaire of n questions, the amount that will answer correctly is calculated by the following expression:

$C = n*\frac{70}{100}$

If $n = 80$ then:

$C = 80 * \frac{70}{100}\\\\C = 56$

Rewrite the expression as an equivalent expression that does not contain powers of trigonometric functions greater than 1.

stich3 [128]

We are asked to express cos^ 3 x in terms of powers of trigonometric functions not greater than 1

cos ^ 3 x is equal to cos x * cos^2 x.
cos^2 x = 1 - sin^2 x.
sin^2 x = (1 - cos 2x) /2

the answer is cos ^ 3 x = cos x * (1 - (1 - cos 2x) /2 )

The ratio of boys to girls in the gym was 4 to 5. How many boys were in the gym if there were 125 girls in the gym?

Anna007 [38]

Answer:

If there are 125 girls, and the ratio is boys to girls, then you can divide 125 by 5 to get the multiplication factor. This would be 25. Now you can multiply 25 by 4 to get how many boys were in the gym, which would be 100. To get back to your original ratio, you can divide 100/125 by 25 on top and bottom to get 4:5, or 4/5. :)
