Answer:
89
Step-by-step explanation:
There are only 30 pages but last page number is 89.
∠ROT=160°
∠SOT=100°
Now ∠SOR= ∠ROT - ∠SOT
∠ SOR = 160°-100°
∠ SOR =60°
It is given that measure of angle ROQ to equals the measure of angle QOS equals the measure of angle POT.
∠SOQ + ∠QOR = 60°
But ∠SOQ = ∠QOR
2∠SOQ=60°
∠SOQ=60°÷2
∠SOQ =30°
Also ∠POT=∠SOQ=∠ROQ=30°
Answer:
D. StartFraction negative 1 + StartRoot 3 EndRoot Over 2 EndFraction
Step-by-step explanation:
Multiply numerator and denominator by the conjugate of the denominator. Then the denominator is the difference of squares, which will be rational. This simplification is called "rationalizing the denominator."

Answer:
Approximately 4 loaves of bread.
Step-by-step explanation:
Let us get out the total amount of flour that Josh has first of all. This is
cups of flour.
Each lof requires
cups of flour. This means that to make a loaf, he will be taking out this quantity of flour from the whole lot.
To get the total number of loaves he can make with this quantity of flour, we will have to divide the total quantity of flour available by the quantity required to make a single loaf.
This will be
÷
=
. This is approximately 4 loaves of bread
