Answer:

Approximate decrease is 70%

Step-by-step explanation:

The percent decrease is the change over the new original / final value.  The change between the old and the new is 850 - 500, which is 350.  Thus the approximate percentage difference is

<u>350</u>

500

A quick way to turn anything with a denominator that starts with 5 and any number of zeros after it ... is to multiply both the top and bottom by 2.  That is, that turns the ratio above to:

<u>700 </u>

1000

Since a percentage is a number of 100, not 1000, just divide everything by 10.  That means take away a zero from each number, which gives you a fraction of:

<u>70 </u>

100

Thus, the result is 70/100, or 70%.

Tyrone saved 24$ of the 60 that he earned mowing lawns .what percent of his earnings did tyrone save
mezya [45]
If 24 of the 60 were saved then the percent saved is

(24/60) x 100

Let's imagine for a second that all 60 was saved, then 100% of the money would be saved. Which makes sense, because

(60/60) x 100 = 100%

So the amount saved dived by the amount earned all times 100 is the percent saved.

How do I convert radians to degrees? Is it pi/180 or 180/pi? I get them confused! Thanks
o-na [289]
It could be either one, depending on whether you intend to multiply or divide.

When you convert, just remember that degrees ==> less radians,
and radians ==> more degrees.  Then you can always check the
results, and make sure that you used the right conversion factor
in the right direction.
