What is the ratio for the surface areas of the rectangular prisms shown below, given that they are similar and that the ratio of
their edge lengths is 3:1
1 answer:
Answer:
9 : 1
Step-by-step explanation:
given a linear ratio = a : b, then the corresponding area ratio is
a² : b²
Here the linear ratio of their edges = 3 : 1, hence
ratio of surface areas = 3² : 1² = 9 : 1

You can see it’s 90
You can also see it because. A triangle is 180 degrees so
45+45=90
180-90=90
So x=90
Answer:
The original point (x , y) —> the point rotated (-y , x)
Step-by-step explanation:
(9x30) =270 (9x7) =63
Distributive Property
Answer:
7 rings = $2.52
then 1 ring will cost = 1/7×2.52
= 0.36
Therefore 1 ring will cost $0.36.
