Ok, so it seems you might have hard time dividing fractions

remember
(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)



1. miles per hour
2/3 miles per 10 minutes
60 minute per mile
10/60=1/6
2/3 miles per 1/6 hour
(2/3)/(1/6)=(2/3)(6/1)=12/3=4
A is answer



2.
cost per pound is cost/poounds
cost=9
pounds=1 and 1/4=5/4
9/(5/4)=(9/1)/(5/4)=(9/1)(4/5)=36/5=7.20

D is asnwer

Bob has to pack 192 boxes. This morning, he packed 84 boxes in 312 hours. If Bob continues at the same rate, how long will it ta
kondor19780726 [428]

Answer:

51.69 hours (see explanation)

Step-by-step explanation:

This question is simple once you break it down:

84 boxes in 312 hours is a rate, so it can be shown in fraction form:

84 boxes / 312 hours

Now to figure out how long it takes to unpack those 192 boxes, just multiply:

192 x 84/312

(192 x 84) / 312

16128 / 312

Now, just divide the numbers:

16128 ÷ 312 = 51.69 hours

It is given that y varies inversely as x^2. If x is decreased by 50%, find the percentage change in y.
vova2212 [387]

Answer:

300%

Step-by-step explanation:

Given

y\ \alpha\ \frac{1}{x^2}

Required

Find the percentage change in y when x decreased by 50%

First, convert to equation

y\ = \ \frac{k}{x^2}

Where k is the constant of proportionality

When x decreased by 50%

Y = \frac{k}{(x - 0.5x)^2}

Y = \frac{k}{(0.5x)^2}

Y = \frac{k}{0.25x^2}

Expand

Y = \frac{1}{0.25} * \frac{k}{x^2}

Substitute \frac{k}{x^2} for y

Y = \frac{1}{0.25} * y

Y = 4 * y

Y = 4 y

The percentage change is then calculated as:

\%Change = \frac{Y - y}{y} * 100\%

\%Change = \frac{4y - y}{y} * 100\%

\%Change = \frac{3y}{y} * 100\%

\%Change = 3 * 100\%

\%Change = 300\%

<em>The percentage in y is 300%</em>
