She was 5 hours on her computer

Number of hours worked = 7\frac{1}{2}

This is an improper fraction so first we convert it

7\frac{1}{2} = > \frac{15}{2}

Time spent on her computer = \frac{2}{3} of working hours

∴ time spent on computer = (15/2)*(2/3)

= 5 hours

Answer:

5 hrs

7 1/2 hours equates to 450 minutes total

2/3 of 450 = 300 total minutes

turning the minutes back into hours, 300 / 60 = <u>5</u>

LuckyWell [14K]
To best estimate the volume of the log, we assume that the diameter is the average of the diameters at both ends giving us 12 inches as the diameter. Thus, the radius is equal to 0.5 ft. The volume of the log is calculated through the equation,
                      V = πr²h = π(0.5 ft)²(10 ft) = 7.85 ft³

66 athletes are running a race. A gold medal is to be given to the winner, a silver medal is to be
Dmitrij [34]

Answer:

274560

Step-by-step explanation:

We can "choose" one of the 66 athletes for the gold medal. That athlete can't win any other medals, so there are 65 athletes left.

We can then "choose" one of the 65 athletes left for the silver medal. That athlete can't win any other medals, so there are 64 athletes left.

We can then "choose" one of the 64 athletes left for the bronze medal.

That leaves us with 66 possible choices * 65 possible choices * 64 possible choices=274560 possible choices
