Answer:
x = 15, 72 degrees
Step-by-step explanation:
4x + 12 + 108 = 180
4x + 120 = 180
4x (+ 120 - 120) = 180 - 120
4x = 60
4x/4 = 60/4
x = 15
4x + 12
4(15) + 12
60 + 12
72 degrees
The length of going from one side of the circle to the (opposite) other side.
Answer:
b. 
Step-by-step explanation:
Here we are given
and are asked to simplify it. We are going to apply the law of exponents which says that

Hence applying this rule in our problem we get, where a=y and n=3

Hence our C) Option is correct
The easiest way to solve a problem like this is to cross multiply and solve
The problem gives us a ratio
2 pounds of granola = 3 pounds of raisins
which makes a ratio of

The other ratio is
? pounds of granola = 24 pounds of raisins
which makes a ratio of

To solve, set them equal to each other ...

Now we must cross multiply...
To cross multiply, we multiply
2 and 24 and we multiply
3 and x Now we have an equation to solve!
3x = 48 To solve and get your final answer, divide...
x =
x = 16
You'll need 16 pounds of granola
