A rock is dropped from a height of 100 feet. Calculate the time between when the rock was dropped and when it landed. If we choo
andre [41]

The time it takes between when the rock was dropped and when it landed is 1.33 seconds.

<h3>What is the time it takes for the rock to land?</h3>

The time it takes the rock to land on the ground from where it is dropped can be determined by using the function given.

The height of the function when it hits the ground will be zero, so the function can be written as:

\mathbf{h(t) =36t^2 -64}

\mathbf{0 =36t^2 -64}

64 = 36t²

\mathbf{t^2 = \dfrac{64}{36}}

t² =1.778

t = \sqrt{1.778}

t = 1.333 seconds

a hard drive is 80% full and has 12000 megabytes of free space. one minute of video uses 60 megabytes of storage. How many minut
Oksanka [162]

Solution: Let x be the total space of hard drive.

We are given 80% space of hard drive is full and 12000 megabytes are free.

We can write:

x-80\% \times x=12000

x-\frac{80}{100}x =12000

\frac{100x-80x}{100}=12000

20x=12000 \times 100

x=\frac{1200000&#10;}{20}

x=60000 megabytes

We have to free 5% of space as the difference between 80% and 75% is 5%.

Therefore 5% of 60000 is:

\frac{5}{100} \times60000=3000

We know that 1 minute of video uses 60 megabytes of space.

Therefore number of minutes of video that should be deleted to make 75% of space free is:

\frac{3000}{60}=50 minutes of video

Hence, 50 minutes of video should be deleted so that the hard drive is 75% full.
