Answer:
The equation to find the number of gallons purchased is:
You purchased 12 gallons of gasoline
Step-by-step explanation:
This problem can be modeled by the following first order function
Where C(n) is the cost in function to the number of gallons, P is the price of the gallon and n is the number of gallons
The problem states that the price of gasoline is $3.05 per gallon, so P = 3.05
The equation to find the number of gallons purchased is:
If you pay $36.60, you have C = 36.60, and want to find n, so:
You purchased 12 gallons of gasoline
Answer:
Find the Equation of a Line Given That You Know Two Points it Passes Through. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept
Step-by-step explanation:
<span>The system which models the situation above is described in D variant:
</span><span>D. h = 3000t. h = 30,000 - 2500t</span>
The given equation is
m = ak/n
We want to solve for k
The first step is to multiply both sides of the equation by n. We have
m * n = ak/n * n
mn = ak
The next step is to divide both sides of the equation by a. We have
mn/a = ak/a
mn/a = k
k = mn/a
The correct option is the second one
Answer:
(a) 896
(b) 1000
(c) 910
Step-by-step explanation:
Number of women = 8
Number of men = 6
A committee consisting of 3 men and 3 women is to be formed.
(a) 2 of the men refuse to serve together.
Number of men who don't want to serve together = 2
Remaining men = 4
Total ways = Both men who don't want to serve together are not selected + only one of them is selected.
(b) 2 of the women refuse to serve together.
Number of women who don't want to serve together = 2
Remaining men = 6
Total ways = Both women who don't want to serve together are not selected + only one of them is selected.
(c)1 man and 1 woman refuse to serve together.
Ways = Total ways - Both man and woman are select who refuse the serve together
