Answer:
1100 brainliest please
Step-by-step explanation:
1000×2×0.05=100
1000+100=110
First one:
cos(A)=AC/AB=3/4.24
cos(B)=BC/AB=3/4.24
Cos(A)/cos(B)=AC/AB / (BC/AB) = AC/AB * AB/BC = AC/BC=3/3=1
Second one:
To solve this problem, we have to ASSUME AFE is a straight line, i.e. angle EFB is 90 degrees. (this is not explicitly given).
If that's the case, AE is a transversal of parallel lines AB and DE.
And Angle A is congruent to angle E (alternate interior angles).
Therefore sin(A)=sin(E)=0.5
Y=-X+4 finding the y intercept, b and slope, mx thus y=mx+b
Answer:
<em>Plan A</em>
Step-by-step explanation:
Plan A -
$7 + 2.50(5)
$7 + $12.50
Plan A = $19.50
Plan B-
$4(5) = $20
Plan A is the cheapest, therefore it is the best plan.
Hope this helped! :)
