Answer:
Step-by-step explanation:
A dependent variable in an expression is one whose value can be determined only when the value of other variable (i.e independent) is known.
A. The cost at the fitness center depends on the number of months (x).
The cost is the dependent variable, and number of months (x) is the independent variable.
f(x) = 100 + 40x
Example, the cost paid for 12 months can be determined as;
f(12) = 100 + 40(12)
= 100 + 480
= 580
Thus, $580 would be paid for 12 months at the fitness center.
B. The lettuce is sold at $1.69 per pound. The cost depends on the number of pounds of lettuce bought.
The cost is the dependent variable, while the number of pounds of lettuce (x) bought is the independent variable.
So that;
f(x) = 1.69x
The cost of 10 pounds of lettuce can be determined as;
f(x) = 1.69(10)
= 16.9
Thus, the cost of 10 lb of lettuce is $16.90.
Answer: 
Step-by-step explanation:
Given : In the Sahara Desert one day it was 136°F.
In the Gobi Desert a temperature of -50°F was recorded.
Clearly , 136°F> -50°F
Then, the difference between these two temperatures will be :-
![136^{\circ}F-(-50)^{\circ}F\\\\=(136+50)^{\circ}F\ \ [\because \text{Product two neagtive sign is positive]}\\\\=186^{\circ}F](https://tex.z-dn.net/?f=136%5E%7B%5Ccirc%7DF-%28-50%29%5E%7B%5Ccirc%7DF%5C%5C%5C%5C%3D%28136%2B50%29%5E%7B%5Ccirc%7DF%5C%20%5C%20%5B%5Cbecause%20%5Ctext%7BProduct%20two%20neagtive%20sign%20is%20positive%5D%7D%5C%5C%5C%5C%3D186%5E%7B%5Ccirc%7DF)
Hence, the difference between these two temperatures =
Answer:
$14.56
Step-by-step explanation:
<u><em>Steps to answering this question </em></u>
- Determine the total number of comics bought. This can be done by dividing the total amount spent on comics by the unit price of a comic
- Determine the selling price of the comic
- multiply the amount of comics bought by the selling price
the total number of comics bought = total amount spent on comics / per unit price of comics
$20.16 / $0.72 = 28
selling price = 0.72 - $0.20 = $0.52
Total amount received = selling price x total comics bought
$0.52 x 28 = $14.56
