A city s location is represented on a map at the origin (0,0). Ted lives 20 miles south and 20 miles west of the city represented on this map. What are the coordinates of Ted's house? (Make sure to place your answer in parenthesis.) ex. (x,y) *
Answer:
(-20,-20)
Step-by-step explanation:
You can draw it out on a graph to see that the point 20 units down (south) and 20 units left (west) is (-20,-20), or you can subtract 20 from both the x and y values. [(x-20),(y-20)]

Step-by-step explanation:
What is the length of AZ?
Use the following information:
A
is between Y
and Z,
YA=22, AZ=16x,
and YZ=166.
The required length of AZ for the line segment YZ is 144.
Given that,
A is between Y and Z,
YA=22, AZ=16x, and YZ=166.
The line is a curve showing the fastestdistance between 2 points.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
YZ = YA + AZ
166 = 22 + 16x
16x = 144
x = 9
Now,
Length of AZ = 16x
= 16 * 9
= 144
Thus, the required length of AZ for the line segment YZ is 144.

Which expression has a value of 90?
Barbra has a part-time lawn-mowing job. The table below shows the amount of money Barbra earned for different numbers of hours of work: Barbaras earnings from lawn mowing number of hours worked money earned (dollars) 5 40 6 48 56 part A: what are the missing numbers in the table? Show your work. (4 points) part b. Barbara also works Part time at a theme park. To the money she earns so 1:9.create a table to show the money earned by Barbara for 5,6 and 8 hours of work at the theme park (3 points) PartC: how many more dollars does Barbara ern working fat the theme park for 5 hours then mowing lawns for 5 hours? Show your work
Answer:
it isn't obvious from your problem statement where the missing numbers are in your table. We have assumed that Barbara charges the same hourly rate for all mowing jobs, so the red numbers were the ones that were missing.
Since we know our times-8 and times-9 times tables, all the work is mental. There is nothing to show. Each number in the Dollars column is 8 times the number in the Hours column.
B) See the table on the right. Again, we know our times tables. 5*9 = 45, and so on.
C) 45 -40 = 5
Barbara earns 5 dollars more at the theme park for 5 hours' work than she does mowing lawns. (Check: The rate difference is $1 per hour, so the difference in earnings will be $5 for 5 hours.)

Write a paragraph, flowchart, or 2-column proof for the following conjecture:
Given: angle 1 = angle 4
Prove: angle 3 = angle 2
Answer:
How I would write my paragraph:
If angle 1 is congruent to angle 4, angle 1 must also be congruent to angle 3 by the transitive property. This is because is angle 3 and angle 4 are vertical angles, and they must be congruent. If angle 1 is congruent to angle 3, then the two lines in the middle must also be parallel due to the converse of the corresponding angles theorem. Because the two lines in the middle are parallel, angle 3 must be congruent to angle 2 by the alternate interior angles theorem.

What is the function of the line?
Answer:
It is a linear function.
Step-by-step explanation:
The graph shows a straight line. Therefore the function must be linear. Unless you were asking about the equation of the line? Let me know.
To find the equation of this line, you would take the two points it passes through, (-3, 0) and (0, -2), and plug it into the slope formula, (y2-y1)/(x2-x1).
This would get you (-2 - 0)/ (0 - (-3)), which is -2/3.
Then, you can use slope intercept form to write the equation, since you have the y intercept already, (0, -2). Slope intercept is y=mx+b.
The line of the equation would then be y = -2/3x -2

a 95% confidence interval is found to be (24, 30). The sample standard deviation is 7.5, and the sample size is 25. If you wanted a smaller interval what could you do?
A. increase the confidence level to 99.7%.
B. increase the sample size to 36.
C. decrease the sample size to 20.
D. None of these.
Answer:B. Increase the sample size to 36
Step-by-step explanation:
First of all, the size of the sample must be greater than 30. Then the correct option is B.
What is a normal distribution?It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
A 95% confidence interval is found to be (24, 30).
The sample standard deviation is 7.5, and the sample size is 25.
First of all, the size of the sample must be greater than 30. Then we have to increase the sample size up to 36.

I need somebody’s help
Answer:
x= 40
so
3x-5= 115
2x-15= 65
Step-by-step explanation:
C is the correct answer. I see that you put a mark on that choice so you are right if you thought that. I hope this helps!
Answer:
C
Step-by-step explanation:
The 2 angles are same- side interior angles and are supplementary, thus
3x - 5 + 2x - 15 = 180, that is
5x - 20 = 180 ( add 20 to both sides )
5x = 200 ( divide both sides by 5 )
x = 40
Thus
3x - 5 = 3(40) - 5 = 120 - 5 = 115°
2x - 15 = 2(40) - 15 = 80 - 15 = 65°

what is the answer plz help.
Answer:
0.2
Step-by-step explanation:
C.O.P-the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX.
So to find that you would divide y by x.
In this case the dot is between 0 and 2 on y so it is 1 and between 4 and 6 on x so it is 5.
Then you would divide 1/5 and get 0.2 or you could look at the end of the graph and notice that the last point is at (10,2) and divide 2/10 and get the same thing.

During a period of extreme cold, the average daily temperature dropped decreased by 1. Feach day. How many days did it take for the temperature to
decrease by 9 F? Which equation would you use to find the solution?
Answer:
The answer is 9 days
Step-by-step explanation:
First, we realise
-1.F = 1 day
-9.F = 9 days
The -1.F times 9 gives us one so the days times 9 as well.
Answer = 9

The furniture store sells each chair (c) for $225. To have them shipped to their house, the store charges $60. If the Browns bought c number of chairs, how much did they spend (s)?
==========================================================
Explanation:
1 chair = 225 dollars
c chairs = 225c dollars .... multiply both sides by c
This shows that buying c chairs costs 225c dollars
c is a placeholder for a positive whole number
Add on the $60 shipping cost to get the total cost 225c+60
Therefore s = 225c+60
