Which graph shows a set of ordered pairs that represent a function?
Need help
Answers
Answer:
The third graph, the top right graph
Step-by-step explanation:
A function when determined graphically is a graph that passes the straight line test, which means if there is any two points on the graph which you can plot a vertical straight line going through both of them it is not a function. If 1 x value is equal to 2 y values, it is not a function.

Penny reads 11 pages in 1/3 hour. What is the unit rate for pages per hour? For hours per page?
Answers
Answer: 33
Step-by-step explanation:
Answer:
33 pages per hour
Step-by-step explanation:
1. To solve for how many pages Penny can read in one hour, we need to write a ratio of pages to hours.
[tex]11: 1/3 = x : 1[/tex]2. Now, 1/3 goes into one, three times. This means that 11 goes into x, three times. We can write "11 goes into x, three times" as: [tex]\frac{x}{11} =3[/tex].
3. (Solving x/11 = 3)
Step 1: Multiply both sides by 11
[tex]\frac{x}{11}*11=3*11[/tex] [tex]x = 33[/tex]Therefore, Penny read 33 pages per hour.

What is the total price of a $45.79 item when a 7% taxe is added
Answers
Answer:
$42.58
Step-by-step explanation:
You would multiply the price of the item (45.79) by the percentage as a decimal (0.07) and subtract the product.
in this case:
45.79x0.07 = 3.205 (rounded 3.21)
45.79-3.21 = 42.58

Answers
The sentence "15% of 4x is 20 less than x"
translates to 0.15 • (4x) = x – 20
Solving that…
0.15(4x) = x - 20 multiplipy 0.15•4
0.6x = x - 20 subtract x from both sides
-0.4x = - 20 divide both sides by -0.4
x = 50

We need to find the rate of how much the taxi driver charges per minute.
Therefore:
We need to pick a precise point on the line ( a precise point is a point with whole number x and y coordinates; no decimals or fractions).
We see that the point (6, 9) is precise.
A rate is a ratio in the form of a fraction that shows the relationship of change between two quantities: a/b.
So, the taxi costs 9 dollars / 6 minutes.
9/6 simplifies 2/3.
And thus, the taxi charges 2 dollars per 3 minutes
So, the answer is 9/6, which can be simplified to the furthest possibility, making it a unit rate.
Answer: 9/6

a. What are the x- and y-intercepts?
b. What do the x- and y-intercepts represent?
Answers
Here we need to plot x and y co-ordinates from the given table.
What are x and y co-ordinates and intercepts ?This is 2D co-ordinate geometry here we have an x axis and a y axis we use co-ordinate geometry to plot lines and curves according to the gives question.when the question consist of linear equations they form straight lines and when questions consists of quadratic and higher degree polynomials they form curves.
a. Here the the days are represented by x and remaing balance are represented by y.
So, when x = 0, y = 20 is co-ordinate form we can represent this as (0,20)
similarly the other co-ordinate points are (1,16), (2,12), (3,8), (4,4), (5,0).
b. x- and y- intercepts represnts the value of one variable corresponding to the other variable.

A tarp is used to keep the infield of a baseball field from getting wet. The infield is a square. The corners of the square tarp are anchored at each base. The tarp is 8,100 square feet.
A. What is the distance between the first and second base?
B. Is 8,100 a perfect square? Explain.
Answers
A. Since the area is 8100 sq ft and the shape is a square (area of a square = length x width) you take the square root of 8100 and get 90 ft as one of the sides. (90 ft x 90 ft = 8100 sq ft)
B. Yes, 8100 is a perfect square. A perfect square is a number made by squaring a whole number. It’s also the product of 2 equal integers. In this case, it’s 90.

Jethro used dimensional analysis to convert one rate of speed to another. Two of the conversion factors he used are 5280 ft/1 mi and 1 hr/60 min. What could be the units of the initial rate of speed and the final rate of speed? Justify your answer.
Answers
The units of the initial and final rates of speed are;
Initial rate of Speed = ft/hr
Final rate of speed = mi/min
We are told that the conversion factors he used are;5280 ft/1 mi and 1 hr/60 min
Now, the meaning of 5280 ft/1 mi denotes that;5280 ft mile is equivalent to 1 mile
This means that the initial distance unit used was ft while the final one was mile
Also, 1 hr/60 min denotes that;
1 hour is equivalent to 60 minutes.
This means that the initial time units used was hour while the final one was minute.
In conclusion, since we know the initial time and distance units used, we can say that the initial rate of speed ft/hr while final speed rate was miles/minutes.Read more at; https://brainly.com/question/17734333
