a. If c is the total number of cars washed and p is the profit
The profit depends on the total number of cars washed.
So profit P is the dependent variable and C is the independent variable
(b) yes, the relationship between c and p a function
Because for each input for c, there will be an unique output for P
(c) C is the number of cars
Each car charged is $5
So C cars charged is 5C
The liquid soap costs $34 and is enough to wash 40 cars. So we subtract 34
Hence Profit P = 5c - 34
The equation is P = 5c - 34
(d) The liquid soap costs $34 and is enough to wash 40 cars
So number of cars is 0 to 40
0<=c <=40
soap costs $34
so profit is above 34
When cars = 40 then profit is 5(40) - 34= 166
So profit lies between 34 and 166
34<= P<= 166
Answer: sorry i don't know the answer :(
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have that the quintuple of 48/25 is:
=(48/25)5
=48x5/25
2- When you simplify, you obtain:
=48/5
3. Then, 3/4 of the quintuple of 48/25 is:
=(48/5)(3/4)
=48x3/5x4
=144/20
=36/5
4. Now, you have:
(9/8)x=36/5
x: the fraction asked
5. When you clear "x", you have:
x=36x8/5x9
x=288/45
x=32/5
The answer is: 32/5
Answer:
X = 45
Step-by-step explanation:
90 + X + A = 180 (angles of a triangle sum to 180)
90 + X + 45 = 180
X = 45
