Answer:
Yes, you have it right
Step-by-step explanation:
The ratio is 2-1, with the length being 1, and the width being 2. The width is always going to be 2 times the amount of length. And you have done it right here. Nice job!
Cotangent of ∠l = adjacent side / opposite side
cotangent of ∠l = - 15/8
Correct option D
We need 30 glass spheres whose TOTAL volume = 3,392.92 cubic inches.
Therefore each of the 30 spheres must have a volume of 3,392.92 / 30 =

Step-by-step explanation:
-3/10x=1/2+7
=15/2
x=15/2×10/-3=-25
-25<1/2
Difference between they both was
1/2-(-25)
1/2+(25)
=51/2
=25.5
The equationi of a line that passes through (x1,y1) and has a slope of m is
y-y1=m(x-x1)
find slope
slope between points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(2,-5) and (-1,1)
slope=(1-(-5))/(-1-2)=(1+5)/(-3)=6/(-3)=-2
a point is (-1,1)
y-1=-2(x-(-1))
y-1=-2(x+1)
slope intercept is solve for y
y-1=-2(x+1)
y-1=-2x-2
add 1
y=-2x-1
