the total cost c of buying b cans of beans can be found using the equation c= $0.79b. What is represented by the dependent varia
1 answer:
Answer:
The total cost is represented by the dependent variable.
Step-by-step explanation:
If we have a function:
x is the independent variable and y is the dependent one, since y is a function of x.
In this problem:
So the total cost of buying b cans of beans is 0.79b. That is, the total cost depends of the number of cans of beans bought.
So the total cost is represented by the dependent variable.

Answer:
Time required to make a pile of 45 sticks next to their fire = 10 minutes
Step-by-step explanation:
This is an example of arithmetic progression.
First term = 5 - 3 + 7 = 9 sticks
Common difference = 7 - 3 = 4 sticks.
So the number of sticks next to their fire is increasing like this
9, 13, 17, 21 .............
term of AP = a + (n-1) d, we need to find n
a + (n-1) d = 45
9 + (n-1) x 4 = 45
(n-1) x 4 = 36
n - 1 = 9
n = 10
Time required to make a pile of 45 sticks next to their fire = 10 minutes
