Answer:
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z ----> the scale factor
x ---> the volume of the model of a swimming pool
y ---> the volume of the actual swimming pool
so
we have
substitute
solve for x
Answer: C.28 hope this helps!
Answer:
So x is the answer.
Step-by-step explanation:
Both x and y have x-coordinate equal to -5 1/2. Of these two points, only x has y-coordinate equal to 2 1/2. So x is the answer.
If the cosine is 1/2, and the angle is acute, then the angle is 60 degrees. Using the rules for a 30-60-90 right triangle, hyp=2 times the short leg. So 7/2= 3.5.
