Answer:

BD = √13cm, AC = 10c,

Step-by-step explanation:

AB^2 = AD^2 + BD^2\\\\49 = 36 + BD^2\\\\BD = \sqrt{49 - 36} = \sqrt{13}cm\\\\AC^2 = AD^2 +DC^2\\

       =36 + 64\\=100

\\AC = \sqrt{100} = 10cm

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.
