Suppose planet A's diameter is approximately 8 times planet B's and both bodies are spheres. What is the ratio of their volumes?
lana [24]

Answer:

The ratio of planet B's volume to planet A's volume is 1:512 or 1/512

Step-by-step explanation:

Volume of sphere = 4/3 π r^3

r = d/2

Radius of palnet A = 8/2 = 4

Radius of planet B = 1/2

Since 4/3 π is same in both volumes so, they cancel out when finding ratio.

Now ratio depends on radius cube of both planets

Volume of Planet B : Volume of Planet A

4/3 π(1/2)^3 :  4/3 π(4)^3

Cancelling  4/3 π on both sides

1/8 : 64

Multiply 8 on both sides

1 : 512

So, The ratio of planet B's volume to planet A's volume is 1:512 or 1/512

Joaquin is ordering 5 identical sandwiches and a bag of chips. The bag of chips cost $1.25 and the entire order costs $38.75. Wr
GenaCL600 [577]

Answer:

A sandwich costs $7.5

Step-by-step explanation:

Given

Represent chips with c and sandwiches with c

c = \$1.25

Total = \$38.75

From the question, we understand that 5 sandwiches were ordered.

Hence, the question of the system is:

5s + c = Total

Substitute values for Total and c

5s + 1.25 = 38.75

Collect Like Terms

5s  = 38.75 - 1.25

5s  = 37.5

Divide both sides by 5

s = \frac{37.5}{5}

s = 7.5
