A patrolman spends 25% every day completing paperwork. The patrolman’s shift each day is 8 hours. How much of his time does he s

fredd [130]

Assuming the man works 8 hours straight without breaks:

25% is the same as 1/4 of something.

So, we just have to figure out what 1/4 (one quarter) of 8 equals.

You can think of it as a pizza cut into 8 slices. One slice is equivalent to one hour for the patrolman.

If we take away 1/2 (half) of the pizza, we have 4 slices, right? Since we start with 8 slices, half of that equals 4 slices. In other words, 50% (half) of the pizza = 4 slices.

Now, 25% (one quarter) of the pizza will equal half of what is left:

If we know that 50%=4 slices (or 4 hours), then 25% must be 2 slices (or 2 hours).

That's it! 25% of 8 hours = 2 hours.

***So, the patrolman spends 2 hours each day completing paperwork.***

Lets check our work:
We know 8 hours (or 8 slices)= 100%
(We know this because
8 slices = 1 whole pizza, or 100% of a pizza. Similarly,
8 hours = 1 whole shift or 100% of the man's shift ).

So

25% + 25% + 25% + 25% = 100%

If 100% of the mans shift = 8 hours:

2+2+2+2 = 8

It checks out!

Hope this helps!

A line has a slope of 9. One of the points on the line is (-2, p). Another point on the line is (2, 2p+1). Determine the value o

igomit [66]

As we travel from (-2, p) to (2, 2p+1), x increases by 4 and y increases by p+1. Note that -2 + 4 = 2 (which is correct), and that p + (p+1) = 2p+1 (which is also correct).

p+1

Thus, the slope of this line is m = rise / run = -------- = 9

4

Then p + 1 = 36, and p = 35.

The time required to complete a job varies inversely as the number of people working. it took 4 hours for 7 electricians to wire

Solnce55 [7]

Let's assign variables

The time required to <span>wire a building: y
</span>
The number of electricians <span>to have done this job: x

</span>
<span>y varies inversely as x

so that:
$y= k\frac{1}{x}$
where k is the proportional constant

To calculate the value of k, plug in the values of x and y:
x=7
y=4

$4=k (\frac{1}{7}) \\~\\k=28$

Now, write down the relation between x and y:
$y=28x$

"</span><span>how long would it have taken 3 electricians to have done the job?"
x=3
Let's find out y:
$y=(28) \frac{1}{3} = \frac{28}{3} =9 \frac{1}{3} =9.333333~~hr$

So it would take 9 hours and 20 minutes to have this job done.
