Answer:
Step-by-step explanation:
Ratio of Cos C using the trigonometric ratios formula, would be:
Adjacent = BC = 40
Hypotenuse = AC = 41
Plug in the values
<span>3x+5y=4...(1)
2x-y=-7...(2)
by(2) : y = 2x+7
subsct in (1) :
3x +5(2x+7) = 4
13x = - 31
x = -31/13
y = 2(-31/13)+7 = 29/13</span>
If 4 kids cut the pizza evenly and one kid ate her slice, I think 7 pieces (if they cut it to 8 pieces)
But the answer would depend on how many slices they cut the pizza into.
Marcus should have substituted -10for b, not 10
Marcus should have subtracted 4(1)(25) in the square root
This equation, when solved correctly, only has one real number solution
So A, C, D
If she does 10 a day she will do 520 after 52 weeks
