For this case we have a direct variation of the form:
Where,
- <em>k: proportionality constant
</em>
We must find the value of k.
For this, we use the following data:
Therefore, replacing values we have:
Rewriting:
Clearing the value of k we have:
Therefore, the direct variation equation is given by:
Answer:
The quadratic variation equation for the relatonship is:
Answer:
$760
Step-by-step explanation:
First off we need to define the amount of feet per square yard.
(3feet= 1yard)
(9 squarefeet = 1 square yard)
Now we find the total area of Amanda's living room.
12 x 15 = 180 sq feet
Now that we have the total area of Amanda's living room, we then divide the total to the number of square feet in a square yard.
180 / 9 = 20 square yards.
Amanda will need a total of 20 square yards to carpet her living room. Now we simply multiply the amount of each square yard to the total amount of square yards that Amanda needs.
38 x 20 = $760
Answer:
$37.08
Step-by-step explanation:
Bought the shirt for - $35
Selling price after tax - $35 + 8%
× 
= 
or 2 
is equal to 0.8
= $2 + $0.8 = $2.08
Selling price after tax = $35 + $2.08 = $37.08
Hope this helps!
Answer:
977.65
Step-by-step explanation:
Add three amounts together divide that number by 3.
2932.95/3=977.65
Hey there!!
Okay here are the steps you can follow!
9 11/12 ----> improper fraction ----> 119/12
2 8/11 ----> improper fraction ----> 30/11
119/12 - 30/11
(119/12 - 30/11) * 132
11(119) - 12(30)
1309 - 360
<u>949</u>
