If you buy 4 shirts you get
50 × .10 = 5
5 dollars off. So you pay
50 - 5 = $45
If you buy 8 shirts (4 shirts twice) it will be
45 × 2 = $90
Hello from MrBillDoesMath!
Answer:
Choice B, -2 sqrt(85) / 85
Discussion:
By definition,
cos(@) = length of side adjacent to angle / hypotenuse
= -2/ ( sqrt ( (-2)^2 + (9^2) ) (usin Pythag. theorem)
= -2/ sqty (4 + 81)
= -2 / (sqrt(85)
Multiply numerator and denominator by sqrt(85):
= (-2 / ( sqrt(85) ) * (sqrt(85)/sqrt(85) )
= -2 sqrt(85) / 85
which is choice B
Thank you,
MrB
