12) the radius is 15 so with the equation (3.14)*r^2, we get (3.14)(15^2)=706.5
13) true, true (if x=4), true
14) y=0.75x+4.50, $8.25
Answer:
The correct answer is 2 feet
Answer: 13
nothing in between 13
Down below
37+61+x=180
98+x=180
x=180-98
x=82°
the third angle is 82°
7/25
Step-by-step explanation:
First we need to determine how many total marbles
9blue+7red+4green+5purple = 25 marbles
P(red) = red/total
