A standard roll of toilet paper is 304 feet long. If Bob walks at a steady rate of five feet per second, how much time does it t
PtichkaEL [24]

Answer:

1.01 minutes

Step-by-step explanation:

The length of the roll is given to be 304 ft, and Bob's velocity is 5ft/s.

Velocity is defined as the rate of change of displacement over time t:

v=d/t\\

The function can be expressed to make t the subject to calculate time taken by Bob;

v=d/t\\\therefore t=d/v, d=304, v=5\\\\t=\frac{304}{5}\times \frac{1}{60}\ min\\\\t=1.01 \ min

Hence, it takes Bob 1.01 minutes to walk the length of the roll.

borishaifa [10]

Answer: Length of other edges will be 7.5 inches, 8 inches, 9 inches, 10.5 inches, 12 inches.

Explanation:

Length of smallest cube = 6 inches

Ratio of similarity to the smallest cube is given as follows:

1) 1.25

So, length of other edge will be

1.25\times 6=7.5\ inches

2) 4:3

So, the length of other edge will be

\frac{4}{3}\times 6=8\ inches

3) 1.5

So, length of other edge will be

1.5\times 6=9\ inches

4) 7:4

So, length of other edge will be

\frac{7}{4}\times 6=10.5\ inches

5) 2

So, length of other edge will be

2\times 6=12\ inches
