Answer:
Step-by-step explanation:
Percent change= (1/4-1/8)/1/4 × 100%
= {(2 -1)/8} ÷ 1/4 × 100%
= (1/8 ÷ 1/4) × 100%
= 1/8 × 4/1 × 100%
=1/2 × 100%
= 50%
It is 50% change
Answer:
B) 50.24 ft^2
Step-by-step explanation:
radius =1/2 diameter = 4

Answer:
l.mao you could just send a picture, it's a bit hard to actually answer any of the questions if it's jam-packed like that
Slope intercept form is

where

is the slope
and

is the y-intercept
they give us that the slope is 2
so our

then to find

, we temporarily plug in the point they gave us for x and y
so

and solve for

3 = 2 + b
1 = b
so our

put this together and we get

as our answer
