Answer:
1)option b
2)option a
Step-by-step explanation:
1) circumference = 62.8 in
=> 2πr= 62.8
=> r= 62.8/(2×3.14)= 10 in
diameter = 2×10 in = 20 in
2)diameter = 14m
radius = 7 m
Area of the circle= πr² =3.14(7)²=3.14×49
= 153.86
=153.9 m²
<span>(4x - 1) + (-5x + 17)
=4x-1-5x+17
= -x +16</span>
So you start at 0 then (1,3) , (2,12) and the other side would be (-1,3) , (-2,12)
so get the people down to unit rates first
Natalie= 40 in 9 minutes
Steven= 10 in 3 minutes
multiply Stevens to get it even
so by 3
30 in 9 minutes
so Natalie paints faster

243 + 62-28 = n
243 + 34 = n
277 = n
n= 277
