Answer:
He has saved $140.
Step-by-step explanation:
Since 35% translates to 0.35, 35% of 400 is (0.35)(400) = 140
Y = -(2^3) = -8 (substitute x=3)
Divide 14 2/5 by 6 to determine the number of pounds each person receives.
Convert 14 2/5 into an improper fraction: 72/5.
Divide 6 into 72/5; the result is 12/5, or 2 2/5 lb.
Each friend receives 2 2/5 lb of the pecans.
I think all you have to do is add all the numbers up. I am sorry if I am wrong about my answer.
The answer
the full question is
If A(x1, y1), B(x2, y2), C(x3, y3), and D(x4, y4) form two line segments, and AB ⊥ CD, which condition needs to be met to prove AB ⊥ <span>CD?
</span>
let be A(x1, y1)B(x2, y2) the first line, and C(x3, y3) D(x4, y4) the second
the slope of the first line is m = y2 -y1 / x2 - x1
the slope of the second line is m' = y4 -y3 / x4 - x3
so the condition needs to be met to prove AB ⊥ CD is
y2 -y1 y4 -y3
m x m' = --------- x ------------ = -1
x2 - x1 y4 -y3
