the longer side / the shorter side must be the same for rectangles to be similar.
For A: 105 / 80 = 1.32
For B: 120 / 90 = 1.33
For C: 100 / 75 = 1.47
So... only A and B are similar.
1). y-3=-2(x+4)
2) slope = 3/4
y+2=3/4(x+4)
y=3/4x +1
3x-4y=4
looks like only the last one
Answer:
Step-by-step explanation:
radius = diameter / 2 = 5/2 = 2.5 in
V = radius^2 x pI x height = 2.5^2 x pi x 8 = 157.1 in^3 (round to the nearest tenth)
cups = Volume of a can / Volume of a cup = 157.1 / 14.44 = 10.9 (round to the nearest tenth)
