Answer:
3/2
Step-by-step explanation:
Slope 1 = (-1+7)/(-5-4) = 6/(-9) = -2/3
Slope 2 perpendicular to Slope 1 :
-1 ÷ -⅔ = 3/2
Answer:
the answer is 9/ 15
Step-by-step explanation:
Sin y = p / h
= 9/ 15 (from y reference )
cos x =b/h = 9 / 15
as from x reference b= 9

Answer:
see below
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
5x+60 + 3x-40 = 180
Combine like terms
8x +20 = 180
Subtract 20 from each side
8x+20-20=180-20
8x= 160
Divide by 8
8x/8=160/8
x=20
5x+60 = 5*20+60 = 160
3x-40 = 3*20-40 = 20
Answer:
Step-by-step explanation:
Flight A :
Checked bag fee = $27
Additional fee per overweight limit = $24
Flight B:
Checked bag fee = $16
Additional fee per overweight limit = $25
Since, the total amount paid for the package on both flights are the same ;
Let x = mass of bag above the weight limit.
Hence, Mathematically ;
27 + 24x = 16 + 25x
24x - 25x = 16 - 27
-x = -11
x = 11
Hence. The bag was s 11kg over the weight limit.
