Pira drives 825 miles to California. The trip takes him 17 hours. He uses 38 gallons of gas on the trip, which costs him $125. Find is speed. Find is gas mileage. Find the unit price he paid for gas.
Speed = Distance / time:
Speed = 825 miles / 17 hours
Speed = 48.529 miles per hour. (Round the answer as needed).
Gas mileage = miles traveled / gallons used
Gas mileage = 825 miles / 38 gallons = 21.71 miles per gallon (Round answer as needed).
Unit rate of gas = Total money spend / gallons bought:
Unit rate of gas = $125 / 38 gallons = $3.289 per gallon.
Answer:
[tex]Speed = 48.53mph[/tex]
[tex]Gas.Mileage = 27.7 mpg[/tex]
[tex]Unit.Price = 3.29/gallon[/tex]
Step-by-step explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
In order to find the Speed we need to divide the amount of total miles in the trip to California by the amount of time that it took.
[tex]Speed = \frac{Miles}{Hours}[/tex]
[tex]Speed = \frac{825.miles}{17.hours}[/tex]
[tex]Speed = 48.53mph[/tex]
Next we can calculate the Gas Mileage by dividing the amount of total miles by the amount of gallons of gas that the trip wasted.
[tex]Gas.Mileage = \frac{Miles}{Gallon}[/tex]
[tex]Gas.Mileage = \frac{825.miles}{38.gallons}[/tex]
[tex]Gas.Mileage = 27.7 mpg[/tex]
Finally, we can calculate the Unit Price by dividing the total amount of money wasted in the trip by the amount of gallons used in that trip.
[tex]Unit.Price = \frac{Total}{Gallons}[/tex]
[tex]Unit.Price = \frac{125}{38.gallons}[/tex]
[tex]Unit.Price = 3.29/gallon[/tex]
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

In a plane, if one line has an undefined slope and another line has a slope of zero, what can you conclude
Answer:
You can conclude that the lines are perpendicular, and will cross at exactly one point.
Step-by-step explanation: If one line has a zero slope, and the other's slope is undefined, that means one line is exactly vertical, and the other is exactly horizontal. This means that they will cross at exactly one point, and are perpendicular.
The slope of a line illustrates the direction of the line
The two lines are perpendicular lines
From the question, we understand that:
A line has an undefined slopeAnother line has a slope of 0As a general rule,
The line with an undefined line is a vertical lineThe line with a slope of 0 is a horizontal lineA vertical line and a horizontal line will meet at a right-angle
Hence, the conclusion about the two lines is that, the two lines are perpendicular lines

The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival. She only spent her money on ride tickets and admission into the festival. The price of admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Define your variables.
(b) Write a linear equation to calculate the cost for anyone who only pays for festival admission and rides.
(c) Explain your answer to Part B.
(a)
Let's assume
y is total cost
x is number of ride tickets
(b)
Since, this is linear relationship
so, we can assume equation as
[tex]y=mx+b[/tex]
The Fall Festival charges $0.75 per ticket for the rides
so,
[tex]m=0.75[/tex]
we can plug it
[tex]y=0.75x+b[/tex]
Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival
so, we have
at x=18 , y=33.50
we can use it to find b
[tex]33.5=0.75*18+b[/tex]
now, we can solve for b
[tex]b=20[/tex]
we can plug it back
and we get
[tex]y=0.75x+20[/tex]
(c)
we got
[tex]y=0.75x+20[/tex]
here ,
y is the cost for anyone who only pays for festival admission and rides
x is number of admission
so, our equation will give total cost
There were 32 volunteers to donate blood. Unfortunately, n of the volunteers did not meet the health requirements, so they couldn't donate. The rest of the volunteers donated 470 milliliters each.
How many milliliters of blood did the volunteers donate?
WRITE ANSWER AS AN EXPRESSION
Answer:
The volunteers donated [tex](15040-470n)[/tex] milliliters of blood.
Step-by-step explanation:
Total number of volunteers was 32 and the number of volunteers couldn't donate blood was [tex]n[/tex].
So, the number of remaining volunteers who donated blood will be: [tex](32-n)[/tex]
Each of these volunteers donated 470 milliliters blood.
So, the total amount of blood donated [tex]= 470(32-n) = (15040-470n)[/tex] milliliters.
Answer:
Answer: The answer to this problem would be (32-n)*470!
Step-by-step explanation:
Since there were 32 volunteers the beginning and some of them couldn't donate you would subtract (the variable you would use is 'n'). As you may know, each means that you multiply so if each volunteer is giving 470 mm of blood each you would multiply that by how many volunteers are remaining which is unknown.
Your final answer would be: (32-n)*470

The fastest recorded Hawaiian lava flow moved at an average speed of 6 miles per hour. The function y=6x describes the distance y the lava moved on average in x hours. Graph the function. Use the graph to estimate how many miles is lava moved after 4.5 hours.
Okay for this problem you can multiply 6 by 4.5 aand get 27 as your answer.
So 6×4.5=27 miles in 4.5 hours
We need to graph a function and use that graph to estimate how many miles lava moves in 4.5 hours.
The graph and estimations can be seen at the end of the answer.
Let's see how to graph this:
We know that the function is y= 6*x
What we need to do, is find two points in the that belong to the line, to get that, we need to evaluate the function in two points:
if x = 0:
y = 6*0 = 0
Then we have the point (0, 0)
if x = 1:
y = 6*1 = 6
Then we have the point (1, 6)
Now to graph the function, we just need to find these two points and draw a line that connects them.
A graph is shown at the end of the answer.
To estimate the distance that the lava has moved in 4.5 hours, we need to find the value 4.5 in the x-axis, then we draw a vertical line that passes through there.
In the point where this vertical line intersects the graph, we draw a horizontal line.
That horizontal line will intersect the y-axis in the correspondent y-value to x = 4.5
An example of this can be seen in the image below, my estimation is that the lava has moved something near 26 miles.

Divide 3/4 by 1/3 and reduce to lowest terms
How to get answer: [tex]\frac{3}{4}[/tex]÷[tex]\frac{1}{3}[/tex]
Apply the fraction rule: [tex]\frac{3}{4} * \frac{3}{1}[/tex]
= [tex]3 * \frac{3}{4}[/tex]
= [tex]\frac{3}{4} * \frac{3}{1}[/tex]
= [tex]\frac{3 * 3}{4 * 1}[/tex]
= [tex]\frac{9}{4 * 1}[/tex]
Answer in fraction form: = [tex]\frac{9}{4}[/tex]
Answer in decimal form: = 2.25
Final answer:
To divide 3/4 by 1/3, multiply 3/4 by the reciprocal of 1/3, which is 3/1, giving you 9/4. This fraction is already in its lowest terms.
Explanation:
To divide fractions, such as dividing 3/4 by 1/3, you need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 1/3 is 3/1. So, you should alter the division problem to a multiplication problem.
Here is the step-by-step process:
Write down the problem in multiplication form: (3/4) * (3/1).
Multiply the numerators together: 3 * 3 = 9.
Multiply the denominators together: 4 * 1 = 4.
You get the result of the multiplication as 9/4.
To reduce to the lowest terms, we see that 9/4 is already in its simplest form as both 9 and 4 are prime to each other.
Thus, when you divide 3/4 by 1/3, the answer in lowest terms is 9/4.

A recording artist receives a royalty payment of 7% for each CD sold, and has an agent who gets 4% of what the recording artist gets. What is the artist’s earnings for the CD if the sales total is $2,500,000 ?
Answer:
The artist's earnings for the CD will be $168000.
Step-by-step explanation:
The total sales amount is $2500000
The artist receives a royalty payment of 7%. So, the amount of royalty, the artist receives will be: [tex](\$2500000\times 7\%)= (\$2500000\times 0.07)=\$175000[/tex]
The agent gets 4% of what the recording artist gets. So, the amount of money the agent gets will be: [tex](\$175000\times 4\%)=(\$175000\times 0.04)=\$7000[/tex]
So, the artist’s earnings for the CD will be: [tex](\$175000-\$7000)= \$168000[/tex]
