I need help with this problem, if you could describe how to do it thats fine aswell, but im a little confused with this

he would charge $4 for half a gallon of milk
Answer:
That it's confusing to you is understandable, these problems are confusing, They take a bunch of real world things and put it into abstract concepts. The graph of the line is just that, an idea of how math represents the cost of the milk.
Step-by-step explanation:
the graph you are given is a straight line, not all graphs are straight lines, but b/c it's a straight line we get to "categorize" it as linear. linear graphs are nice to work with, as compared to curvey ones. aka non-linear. There are a few famous formulas that go along with linear graphs. Remember graphs are just representations of info in a way that we can use math to understand that real thing in abstract ways.
the problem asks what is the slope of the line. Think of the idea of a mountain slope here, when we look at the graph.. and move over it like we would read, from left to right, the graph moves up hill.. or positive, so this graph is a positive slope graph. now we just need to figure out a way to say that with numbers.
often times slope is represented with the variable 'm' . why 'm' you ask? it's just a convention, it's not important which letter you use to represent slope but by convention we use 'm' There is a formula for slope that goes like this,
m = (y2-y1) / (x2-x1)
we can use that to find the slope of this line, but we already know it's positive just by quickly looking at the graph.
the x's and y's in the formula are the x and y points of some exact point on the graph that we can find just by looking at the graph. :) yes we get to make our own points. P1 and P2 ( point 1 and point 2)
somebody has already made two nice black dots, on your graph for you, let's use those two black dots, you don't have to, but those do look convenient. :)
using those two black dots and going from left to right.. I see the 1st point as P1 = (x1,y1) =( 2,10) and the second point as P2 = (x2,y2) = (4,20)
then plug those into the above fomula
m = (20-10) / (4-2)
m = 10 / 2
m = 5
yep, it's positive and steep up , that the answer to (a)
for (b)
we just need the formula called the point slope
y = mx + b
since we know m
y = 5x + b
for use b = 0
so just
y = 5x
now plug in x= 1/2, for the 1/2 gallon of milk
y = 5(1/2)
y = 2/5
that's (b) :)

Jaden cut a square sheet of paper in half along a diagonal to make two equal
triangles. Each triangle has an area of 0.08 square units. What is the length,
in units, of one side of the square?
Answers
0.16/4 = 0.04
The length of one side of the square is approximately 0.4 units.
Let's assume that the side length of the square is "s" units.
When the square sheet of paper is cut in half along the diagonal, it forms two equal right-angled triangles. The area of each triangle is given as 0.08 square units.
The formula for the area of a right-angled triangle is:
Area = (1/2) * base * height
Since the triangles are equal, we can write:
0.08 = (1/2) * base * height
Now, let's find the base and height of one of the triangles. Since the triangle is a right-angled triangle, the base and height are the legs of the triangle.
Let's assume the base and height of one triangle are "b" and "h," respectively.
0.08 = (1/2) * b * h
We are given that the area of each triangle is 0.08 square units, so we can write:
0.08 = (1/2) * s * s
Now, we can solve for "s":
[tex]s^2 = 0.08 * 2\\s^2 = 0.16[/tex]
Take the square root of both sides:
[tex]s = \sqrt{0.16}\\s \approx 0.4[/tex]
So, the length of one side of the square is approximately 0.4 units.

One person takes up about 2.5 square feet of space. Use this value to estimate how many people can fit
in an area that is 20 feet wide and 25 feet long.
Answers
An area that is 20 feet wide and 25 feet long will be 20*25 = 500 square feet large. Division tells us how many times one number is contained within a number, so to find how many 2.5 square feet large people fit in a 500 square feet large space, we do 500/2.5 = 200 people.

Given:
Volume of triangular prism is 67.5 cubic feet
Height of triangular prism is 3 feet
Base width of triangular prism is 5 feet
Length of triangular prism is 't'
To find:
Value of 't'
Steps:
The formula for volume of triangular prism is,
volume of triangular prism = [tex]\frac{1}{2}[/tex] × Width × Height × Length
67.5 = [tex]\frac{1}{2}[/tex] × 5 × 3 × t
67.5 = [tex]\frac{1}{2}[/tex] × 15 × t
[tex]\frac{67.5}{15} = \frac{t}{2}[/tex]
[tex]4.5 = \frac{t}{2}[/tex]

A plane is flying at an altitude of 17,000 feet. The angle of depression from the plane to the airport on the ground is 21°. What is the distance between the plane and the airport to the nearest 10th of a foot
Answers
Answer:
47,433.0 feet
Step-by-step explanation:
Using the SOH CAH TOA identity
Height of the plane = opposite = 17000feet
distance between the plane and the airport = hypotenuse = x
Angle of depression = 21 degrees
Since Sin theta = opp/hyp
Sin 21 = 17000/x
x = 17000/sin21
x = 17000/0.3584
x = 47,433.0
Hence the distance between the plane and the airport to the nearest 10th of a foot is 47,433.0 feet
Answer:
47437.3

Consider best strategy to solve the problem. If 9 inches are equal to 27 feet on a map how many feet are equal to three inches
Answers
Answer:
9
Step-by-step explanation:
If 9 inches equal 27 what you would do is divide in order to find how much feet would be in 1 inch. So:
9/27= 3 feet
Then to find how much feet are equal to 3 inches you just multiply that by 3. So your answer is 9 feet.
Overall the work should look like
9 inches= 27 feet
9/9 inches= 27/9 feet
1 inch = 3 feet
3 inches x 3 feet
= 9

A salesman earend a $325 salery this month. His total sales were $700. If the salesman earend a total of $360. What was his commission rate?
Answers
Answer:
Commission rate= 5% of sales
Step-by-step explanation:
Giving the following information:
Fixed salary= $325
Monthly salary= $360
Sales= $700
First, we need to calculate the commissions:
Commission= monthly salary - fixed salary
Commission= 360 - 325
Commission= $35
Now, the commission rate:
Commission= commission rate* sales
35 = commission rate*700
0.05= commission rate
commission rate= 5% of sales
