The correct equation to use is A. n+d=27 0.05n+0.10d=1.95
Plug 50 into y and find x.
5x + 10 (50) = 800
5x + 500 = 800
5x = 800 - 500
5x = 300
x = 300 ÷ 5
x = 60
Answer:

Step-by-step explanation:
Slope is negative reciprocal when two lines are perpendicular
m1=1/2 therefore m2=-2
The equation of the line in point-slope form is given as

Here m=-2 and (x1, y1)=(-3, -1)
Therefore,

Answer:
360
Step-by-step explanation:
24 divided by 6 = 4 which means each foot = 4 foot shadow
90 x 4 =360
