You can put this solution on YOUR website! 1. Determine the constant of variation for the direct variation given.
R varies directly with S.
----
R = kS
----
When S is 16, R is 80.
80 = k*16
k = 5
--------
-------------------
2 Tomar's paycheck varies directly with the hours he works.
p =kh
----
When Tomar works 5 hours, he gets paid $60.00.
60 = k*5
k = 12
---
Equation:
p - 12h
-----
How much does Tomar make in 8 hours?
p = 12*8
p = 96
-------
3. Y varies directly with X and has a constant rate of change of 6.
y = 6x
---
When the value of Y is 11, then the value of X could be _____.
11 = 6x
x = 11/6
--------
less than 2
--------------------
4. Determine the constant of variation for the direct variation given.
(0, 0), (3, 12), (9, 36)
k = (12-0)/(3-0) = 4
------
5. Select all of the following that are a direct variation.
Songs are 99 cents each to download. yes
------
Tickets for rides at the fair are $1 each. yes
-----
Arcade games are 50 cents or $1. no
-----
To go tubing it is $5 to rent the tube and $7 for each hour. yes
-----
6. Determine the constant of variation for the direct variation given.
Fat calories varies directly with the grams of fat.
c = kf
---
There are 27 calories for each 3 grams of fat.
27 = k*3
k = 9
-------
