The gas tank in Sampson’s car has a capacity of 19.1 gallons. On a trip to see his cousin, Sampson begins with 12.8 gallons of gas in the tank. He stops after driving for 2 hours and fills the tank to capacity with 14.4 gallons. When Sampson arrives at his cousin's house, he has 3.7 gallons of gas left. How much gas, in gallons, did Sampson use on his trip?
Answer:
The answer would be 23.5 gallons of gas.
Step-by-step explanation:
You take away 14.4 gallons from the max capacity (19.1). Which gets you 4.7, the you take that away from 12.8 gallons. Which gets you 8.1 gallons. Then you take away 3.7 from 19.1 (15.4). Then add 8.1 and 15.4(23.5) So 23.5 is how many gallons of gas was used.
Hope this helps!
We want to see how much gas did Simpsons use on the trip.
The total amount of gas used in this trip is 23.5 gallons of gas.
We know that:
The maximum capacity of the tank is 19.1 gal.
The trip starts with 12.8 gal on the tank.
After two hours, he fills the tank to capacity with 14.4 gal.
Then at this moment, he had:
19.1 gal - 14.4gal = 4.7 gal.
Knowing that he started with 12.8 gal, this means that at this point the total amount of gas used is:
12.8 gal - 4.7 gal = 8.1 gal.
Ok, now the car has 19.1 gal of gas. We know that at the end of the trip, the car has 3.7 gallons of gas, then the amount consumed this time is:
19.1 gal - 3.7gal = 15.4 gal
The total amount consumed is:
8.1gal + 15.4 gal = 23.5 gal
So we can conclude that the total amount of gas used in this trip is 23.5 gallons of gas.

Central Market sells 5 jars of jam for $3.00. Valley Market sells jars of jam at 59 cents per jar. Yasmin bought 10 jars from Central Market, and Nadia bought 10 jars from Valley Market.
Answer:
Yasmin will spend $6
Nadia will spend $5.9
Step-by-step explanation:
Step one:
the cost of 5 jars at Central market is $3
the cost of 1 jar = 3/5= $0.6
60 cents per jar
we are told that Valley Market sells jars of jam at 59 cents per jar.
$0.59
Step two:
If Yasmin buys 10 jars from Central Market,
Yasmin will spend = 10*0.6= $6
If Nadia buys 10 jars from Valley Market.
Nadia will spend = 10*0.59= $5.9
The market difference is 6-5.9= $0.1
A car is 180 inches long a truck is 75% longer than the car how long is the truck
Answer: 315 inches
180×.75=135
180+135=315
I hope this is good enough:
The length of the truck is 315 inches.
Let the length of car be C.Let the length of truck be T.Given the following data:
Length of car = 180 inchesTo find the length of the truck:
Translating the word problem into an algebraic expression, we have;
75% of C = [tex]\frac{75}{100}[/tex] × [tex]180[/tex]
= [tex]75[/tex] × [tex]1.8[/tex]
75% of C = 135 inches
Now, we can find the length of the truck:
[tex]T = 135 + C\\\\T = 135 + 180[/tex]
Length of truck = 315 inches
Therefore, the length of the truck is 315 inches.

Consider the graph of f(x) given below.
The function g(x) is a transformation of Rx). If g(x) has a y-intercept of -2, which of the following functions could represent g(x)?
A. g(x) = f(x) - 5
B. g(x) = f(x - 5)
C. g(x) = f(x + 2)
D. g(x)=f(x)-2
g(x) = f(x + 2) represent g(x) since it has a y-intercept of -2.
Option C is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The function g(x) has a y-intercept of -2.
This means that g(0) = -2.
In other words, when x = 0, the value of g(x) is -2.
Now,
Let's look at each of the functions given and see if they could represent g(x).
A.
g(x) = f(x) - 5
For x = 0,
g(0) = f(0) - 5
Since we know that g(0) = -2,
We can substitute this value and solve for f(0).
-2 = f(0) - 5
f(0) = 3
So, if g(x) = f(x) - 5, then f(0) = 3, which means that this function does not have a y-intercept of -2 and therefore cannot represent g(x).
B.
g(x) = f(x - 5)
If we set x = 0 in this equation,
g(0) = f(-5)
This equation tells us nothing about the value of the y-intercept of g(x), so we cannot determine whether or not this function could represent g(x).
C.
g(x) = f(x + 2)
If we set x = -2 in this equation,
g(-2) = f(0)
Since we know that g(-2) = -2, we can substitute this value and solve for f(0).
-2 = f(0)
f(0) = -2
So, if g(x) = f(x + 2), then f(0) = -2, which means that this function could represent g(x).
D.
g(x) = f(x) - 2
If we set x = 0 in this equation,
g(0) = f(0) - 2
Since we know that g(0) = -2, we can substitute this value and solve for f(0).
-2 = f(0) - 2
f(0) = 0
So, if g(x) = f(x) - 2, then f(0) = 0, which means that this function does not have a y-intercept of -2 and therefore cannot represent g(x).
Therefore,
g(x) = f(x + 2) represent g(x) since it has a y-intercept of -2.

3/8 (3/4+5/6) - 1/2
Answer:
3/32
Step-by-step explanation:
1. 3/8 (3/4 + 5/6) - 1/2
2. 3/8 x 19/12 - 1/2
3. 19/32 - 1/2
4. 3/32
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
First, you do the operation order. In this equation, parentheses goes first. You add the fractions to get 19/12.
Then, we multiply the sum from the parentheses and 3/8, 19/32.
Finally, we subtract the product we got from the parentheses and 3/8 with 1/2, each lead us to our final answer 3/32.

Point p is located in the first quadrant of a coordinate plane.If p is reflected across to form p',choose the four statements that will always be true.
Answer:
When we do a reflection of a point (x, y) about a given line, the distance between the point (x, y) and the line is invariant under the transformation.
In the case of reflection over x-axis we have:
T (x, y) => (x, -y)
In the case of reflection over the y-axis, we have:
T (x, y) => (-x, y)
Because these two lines are perpendicular, a reflection over the x-axis leaves the distance between the point and the y-axis invariant (and the same for the inverse case)
Then 4 statements that will always be true:
1) The distance between p' and the x-axis is the same as the distance between p and the x-axis.
2) The distance between p' and the y-axis is the same as the distance between p and the y-axis.
From 1 and 2, we get:
3) The distance between p' and the origin is the same as the distance between p and the origin.
4) As we have a reflection, p' can not be in the same quadrant than p, then p' can not lie on the first quadrant.
