Answer:
C = 100 + 0.20d
Step-by-step explanation:
Let
C = Total cost
d = distance driven(km)
$100 = fixed cost
$0.20 = additional cost
The algebraic model of the relationship:
Total cost = fixed cost + (additional cost * distance driven(km))
C = 100 + (0.20 * d)
C = 100 + 0.20d

Which statement best describes the solution to this system of equations?
3x + y= 17
x+2y= 49
OA.
It has no solution.
B.
It has infinite solutions.
O c.
It has a single solution: x = 15, y= 17.
OD
It has a single solution: x= -3, y = 26.
Answer:
X= –3, y=26
Step-by-step explanation:
3X+Y=17====> –2(3X+Y)=–34===> –6X–2Y=–34
X+2Y=49
Aight so let's head to the sum
–5X=15===> X=–3
–3+2Y=49===> 2Y=52===> Y=26

You and your best friend are both on the swim team. You want to beat your friend at the next swim meet so you decide to swim 15 minutes longer than she does one day at practice. Write an equation for the number of minutes you swim, y, when your friend swims x number of minutes. You swim 55 minutes. How many minutes did your friend swim?
Answer:
y=x+15
Friend swims 40 minutes
Step-by-step explanation:
We re told that you want to swim 15 minutes longer than your friend. In word problems, longer or more always means addition. This means we will add 15 minutes to your friend's swim time (x) so we can figure out how long you swam (y).
This gives us the equation: y=x+15
Part two:
We know that you swam 55 minutes. This means y=55.
55=y=x+15
55=x+15
Now we want to get x alone, or isolate it. We can do this by subtracting 15 from both sides.
55-15=x+15-15
15-15= 0 and 55-15= 40
40=x
Thus your friend swam 40 minutes
(Remember that whatever you do to one side of the equation, you have to do to the other. If you add 2 to the left hand side, you have to add 2 to the right hand side. If you, like we did above, subtract 15 from the right, you have to subtract 15 from the left too)
In a carnival drawing, a yellow ticket wins $1, a green ticket wins $5, and a blue ticket wins $10. There are 20 green tickets, 25 yellow tickets and 5 blue tickets. In simplest form, what are the odds in favor of winning $5 or more?
A. 1:1
B. 1:2
C. 2:1
D. 1:3
Answer: B. 1:2
Step-by-step explanation: Since there are 20 green tickets and 5 blue tickets that means there are 25 tickets that could win $5 or above and the total number of tickets are 50. That means there is a 25/50 chance you could win a ticket above $5. If you simplify the ratio you will get 1/2 or 1:2
The odds in favor of winning $5 or more is 1:2.
In a carnival drawing, a yellow ticket wins $1, a green ticket wins $5, and a blue ticket wins $10. There are 20 green tickets, 25 yellow tickets and 5 blue tickets.
What is the odd?
Odd refers to a number that will have a remainder of 1 when divided by 2. Odd also describes something that is unusual or weird. Odd has many other senses.

A number n times 33, decreased by 135, is 360. A number m times 18, added to 90 is 360. Write and solve an equation for each variable. Then compare the values of n and m.
Answer:
N = 6.8181. and m= 15
Step-by-step explanation:
33n-135=360
33n = 360-135

Step-by-step explanation:
8/4=2
x^3/x^2=x
y^5/y^3=y^2
Answer:
2xy^2
Step-by-step explanation:
First, 8/4 is 2.
2x^3y^5 / 4x^2y^3
Then, we can bring the x^2 up. It becomes the -x^2. Combined with the x^3, we have x. Finally, we can bring the y^3 up, where it becomes -y^3. Combined with the y^5, we get y^2.
Our final answer is 2xy^2.

Margaret bought a video game, her father gave her 0.2 of the money, her aunt gave 0.5 of the money and she saved the rest. She saved $168 so what amt of money did her father give
Answer:
if Im correct it should be $8.40
Step-by-step explanation:
why well if you think of breaking down by say 1/4 of 168 all you do is divide 4 which is the whole amount by 0.2 which is the amount the father gave her so 4/0.2= 20 the you take your whole 168 and divide by 20 which the whole number for 0.2 the your answer should be this 168/20= 8.4 which then i assumed it was $8.40 hopefully that is correct hehe

Describe the location of point (-3, -2, 3) in three-dimensional coordinate space.
Answer:
The usual way to draw a 3-D grid can be seen below.
The positive z-axis points upwards
The positive y-axis points to the right
The positive x-axis points towards you, or to the front.
And the notation for a point in 3-D is (x, y, z)
In this case, our point is (-3, -2, 3)
Then the location of the point can be described as:
So the x-value is -3, which means that the point is 3 units behind the origin.
The y-value is -2, which means that the point is 2 units at the left of the origin
The z-value is 3, which means that the point is 3 units above the origin.
Find he probability of no more than 35 defective CD's in a batch of 80 CD's if the probablility of any one CD being defective is 0.1.
Answer:
0.999999
Step-by-step explanation:
Given that :
Probability of CD being defective, p = 0.1
q = 1 - p = 1 - 0.1 = 0.9
Total number of CD's = number of trials = 80
Probability, that no more than 35 CD's are defective ;
The question satisfied the requirements for a binomial probability problem ;
Recall :
P(x = x) = nCx * p^x * q^(n-x)
Hence,
P(x ≤ 35) = 80C35 * 0.1^35 * 0.9^(45)
Using calculator to save computation time :
P(x ≤ 35) = 0.999999

Answer:
(3x - 4) (2x + 15)
Step-by-step explanation:
6x² + 37x - 60
Using "splitting the middle term" method,
we get;
6x² + 45x - 8x - 60
= 3x (2x + 15) - 4 (2x + 15)
= (3x -4) (2x + 15)
The 12th term of the arithmetic sequence is 10.5. The 18th term of this sequence is 13.5. Find the common difference and the first term.
Answer:
Common difference = 0.5
First term = 6.
Step-by-step explanation:
the 12th term a12 = a1 + d(12-1) where a1 = first term and d = the common difference.
So a1 + 11d = 10.5 ....(A) Similarly:
a1 + 17d = 13.5....(B)
Subtracting equations:
(B) - (A) :-
6d = 13.5 - 10.5 = 3
d = 3/6 = 0.5
From equation (A):
a1 + 11(0.5) = 10.5
a1 = 10.5 -5.5 = 5.
