Write an equation and then solve each word problem: My computer can download a movie in 5 hours. If I install an extra processor
Murrr4er [49]

Answer:

The new extra processor would take 20 hours to download the movie.

Step-by-step explanation:

This word problem presents two variables: n - Processing capacity, dimensionless; t - Download time, measured in hours. Both variables exhibit a relationship of inverse proportionality, that is:

t \propto \frac{1}{n}

t = \frac{k}{n}

Where k is the proportionality constant.

Now, let suppose that original processor has a capacity of 1 (n = 1), the proportionality constant is: (t = 5\,h)

k = n\cdot t

k = (1)\cdot (5\,h)

k = 5\,h

The equation is t = \frac{5}{n} and if time is reduced to 4 hours by adding an extra processor, the processing capacity associated with this operation is: (t = 4\,h)

n = \frac{5}{t}

n = \frac{5\,h}{4\,h}

n = 1.25

Then, the extra processor has a capacity of 0.25. The time required for the new extra processor to download the movie is: (n = 0.25)

t = \frac{5\,h}{0.25}

t = 20\,h

The new extra processor would take 20 hours to download the movie.

vova2212 [387]

Answer:

117 pounds

Step-by-step explanation:

the ratio is given:

4 : 5

Colin : Dan

Simplest way to solve:

4x = 52

x = 52/4 = 13

now, x is one part of the share.

There are 9 total parts:

9 x 13 = 117.

Hope this helps
