Answer:

Step-by-step explanation:
Remember that

we have

In this problem
b represent the 100%
so
using proportion
Find out what percent of b represent a
Let
x -----> the percentage of b

Convert to mixed number

What do you mean by this?
Answer: Well since the ratio is 9:7 for red to blue well transfer that first by finding out the blue if there are 117 xc=9:7x13 would be 117 red and 7x13=91 blue so the new ratio is 117:91.
So now we add which I'm sure you can do,
117
+
91

Answer:
The answer is the option C

Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal angles
The two equal angles are called the base angles, and the third angle is called the vertex angle
In this problem we have the isosceles triangle TIC
∠I=
-----> vertex angle
∠T=∠C -----> base angles
Remember that the sum of the internal angles of a triangle is equal to 
so
∠I+∠T+∠C=
∠I+2∠T=
Substitute
+2∠T=
Solve for angle T
2∠T=
∠T=
∠T=
