If the first chapter of a certain book is 16 pages long and makes up 4% of the book, how many pages does the entire book have?
galina1969 [7]
If 16 pages equal to 4%, how many pages will equal to 100%?

4/100 = 16/x
4x=1600
X= 400

So total pages should be 400.

What is tan angle QTR if line PR is tangent to circle T at Q, and TS = 1 cm?
lions [1.4K]
Tangent = opposite / adjacent

In the diagram:
TQ is the short leg or the opposite
QR is the long leg or the adjacent
TR is the hypotenuse. TS is part of the hypotenuse.

Tan(QTR) = TQ / QR

TS = 1 ; TQ = TS  so, TQ = 1

Tan(QTR) = 1/QR

I think the answer is C.RQ
