The greatest common factor between these 2 numbers is 6
In its decimal form, it says ' 64 / 100 '.
In order to change it to its lowest terms, we look to see whether the
numerator and denominator have a common factor greater than ' 1 '.
If they do, then we can divide numerator and denominator by their
common factor, and have the same fraction in lower terms.
The common factors of 64 and 100 are 1, 2, and 4 .
We could divide top and bottom by 2, but that wouldn't finish the job.
It's always best to divide them by their <u>greatest</u> common factor, and
once you do that, you're done.
Dividing the numerator and denominator both by 4,
we get the fraction in its lowest terms:
0.64 = 64/100 = <em>16/25</em>
Answer:
<em>The products did cost $173.9 in 2010</em>
Step-by-step explanation:
<u>Exponential function</u>
Two variables y and x are related as an exponential function if they comply:
where C is the initial value of F, r is the ratio, and k is a proportional constant.
The situation described in the question is modeled as
Where F is the final value of the cart of groceries in 2010, C = $150 is its value in 2005, r is the yearly rate of increase. n is the number of years
. So
If we set n=5 (from 2005 to 2010):
The products did cost $173.9 in 2010
Answer:
34.8%
Step-by-step explanation:
$600+15%
=600+15/100*600
=600+90
=$690
You have $450 and you want to purchase a product of $690(regular price+sales tax)
$690-$450
=$240
Percentage of $240 discount
=240/690*100
=34.78%
Approximately 34.8%
X/6 + 4 = 15
First, subtract 4 to both sides:
x/6 = 11
Now multiply 6 to both sides:
x = 66
