marcus's favorite casserole recipe requires 3 eggs and makes 6 servings. Marcus will modify the recipe by using 5 eggs and increasing all other ingridients in the recipe proportionally. what is the total number of servings the modified recipe will make?
The modified recipe will make a total of 10 servings.
what is the total number of servings the modified recipe will make?Since Marcus is using 5 eggs in the modified recipe instead of 3, we can calculate the ratio as follows:
Ratio = (Number of eggs in modified recipe) / (Number of eggs in original recipe)
Ratio = 5 eggs / 3 eggs
Next, we need to apply this ratio to the number of servings in the original recipe. Since all other ingredients are being increased proportionally, the number of servings will change accordingly.
Total Servings in Modified Recipe = (Number of servings in original recipe) * Ratio
Given that the original recipe makes 6 servings, we can substitute the values:
Total Servings in Modified Recipe = 6 servings * (5 eggs / 3 eggs)
Total Servings in Modified Recipe = 6 * (5/3)
Total Servings in Modified Recipe = 10
Therefore, the modified recipe will make a total of 10 servings.

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

GEOMETRY HELP! What is the equation of a line that passes through the point (1, 8) and is perpendicular to the line whose equation is y=x/2+3 ?
A perpendicular line has the negative reciprocal slope of the given line.
The slope of the given line is x/2, which can be written as 1/2x
The negative reciprocal of 1/2 would be -2
The equation for a line is written as y = mx +b, where m is the slope and b is the y-intercept.
We already have the slope ( -2)
So we can solve for b by replacing y x and m with the slope and the point given:
8 = -2(1) +b
8 = -2 + b
b = 10
The equation would be y = -2x + 10

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]

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]

Answer: (6, -10)Jacob drew a regression line for this paired data set
His line passed through (2,10) and (7,18)
What is the equation of Jacobs regression line?
A)y=6.8x+1.6
B)y=1.375x+4.25
C)y=0.625x-4.25
D)y=1.6+6.8
Answer: [tex]y=1.6x+6.8[/tex]
Step-by-step explanation:
1. The equation of a regression line has the following form:
[tex]y=mx+b[/tex]
Where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
2. You need to calculate the slope with the points given in the exercise:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
3. Substitute values:
[tex]m=\frac{18-10}{7-2}[/tex]
[tex]m=\frac{8}{5}=1.6[/tex]
4. Now, you must calculate [tex]b[/tex]:
-Substitute the value of the slope into the equation above.
- Take one of the given points and substitute them into the equation.
Then:
[tex]y=mx+b\\10=(1.6)(2)+b\\b=10-3.2\\b=6.8[/tex]
5. Therefore, the equation is:
[tex]y=1.6x+6.8[/tex]
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.

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
