Ronnie misses the school bus 1 out of every 30 school days. He sets up the proportion 1/30=180/x to predict how many days he wil
bija089 [108]

Answer:

1/30=x/180

Step-by-step explanation:

The way that Ronnie wrote his proportion is wrong since 180/x is saying that he will miss 180 days of school. The fraction 1/30 means that he would miss 1 day out of 30 days, which is correct. But the fraction 180/x would mean that he is missing 180 days of school, which is wrong.

Solving:

1/30=x/180

180/30=6

1 x 6 = 6 days

He will miss 6 days of school in 180 days.

Evgesh-ka [11]
The volume formula could be re-written to help understand this, as V = π*3r^2*3h. If you solve for this, you can conclude that the volume would be multiplied by 27.
