Answer:
50.24 units^2
Step-by-step explanation:
Area of circle formula:
r^2
r = 4,
= 3.14
3.14 * (4^2) = 3.14 * 16 = 50.24
m<E=45.5 m<F=45.5
this is question 8 can't see question 9
An hour and 15 minutes i believe. not 100% though
Answer=7 minivans
45/7=6.4
since you can't have 0.4 minivans, we round up 6.4 to 7
solve this answer by using substitution. set the first equation to x=-y+4 then substitute -y+4 for x in the second equation.
2(-y+4) + 3y=0
-2y+8 + 3y=0
y+8=0
y=-8
now use -8 and solve for x
x+(-8)=4
x=12
