Answer:
z=90
Step-by-step explanation:
Answer:
12x+11 = 47 (reason: vertical angles)
12x = 36
x = 3
12(3)+11 + w = 90 (reason: right angles)
36+ 11 + w = 90
47+w = 90
w = 43
43+z+47 = 180 (reason: linear pair)
90+z = 180
z = 90

divide the sum of 7/9 and 2/3 by 5/3
Answers
Answer:13/15
Step-by-step explanation:
Add 7/9 and 2/3 the answer is 13/9 then divide it by 5/3 in order for you to divide get the reciprocal of 5/3 which is 3/5 then multiply it and you well get 13/15
Answer:
13/15
Step-by-step explanation:
The answer is 13/15 because:
1) In order to figure out what 7/9 + 2/3 is, we need to find the common denominator. The common denominator is 9 because 3 contains the factor 9.
7/9 + 6/9 = 13/9
We need to multiply the denominator to get to 9: 3 x 3 = 9. We have to multiply the numerator as well: 2 x 3 = 6.
2) Next, we have to divide 13/9 and 5/3. In order to divide we have to find the reciprocal of the second number. Reciprocal means to flip the fraction. The reciprocal of 5/3 is 3/5.
3) Finally, we just have to multiply 13/9 and 3/5 which is 39/45. 39/45 in simplest form is 13/15.

Two months ago, the mean daily rainfall in a local city was 9. 4 cm. The mean absolute deviation was 3. 5 cm. Last month, the mean daily rainfall in that city was 11. 5 cm, and the mean absolute deviation was 1. 6 cm. Which statement about the rainfall is true? More rain fell two months ago than last month. About the same amount of rain fell two months ago as last month. Last month, the amount of rain that fell each day varied about the same as the month before. Last month, the amount of rain that fell each day varied less than the month before.
Answers
Last month the amount of rain that fell each day varied about the same as the month before is the right statement about the rainfall, Option c is correct.
What is the mean absolute deviation?The average distance between each data point and the mean is the mean absolute deviation of a dataset. It offers us an indication of how variable a dataset is.
The given data in the problem is;
Two months ago,
The mean daily rainfall in a local city was 9. 4 cm.
The mean absolute deviation was 3. 5 cm
Last month
The mean daily rainfall in that city was 11. 5 cm
The mean absolute deviation was 1. 6 cm.
We can see that there was less variation last month than the month before since the mean absolute deviation is a measure of variance.
Hence Last month the amount of rain that fell each day varied about the same as the month before is the right statement about the rainfall, Option c is correct.

100 POINTS HEELP PLSSS!!!
Answers
Answer:
See below.
Step-by-step explanation:
1.
y = 100 + 65x
y = 40 + 80x
100 + 65x = 40 + 80x
-15x = -60
x = 4
y = 100 + 65x = 100 + 260 = 360
(4, 360)
2.
The lines intersect at the point (4, 360).
At the point of intersection, where x = 4, it shows that by doing 4 hours of labor, both shops cost the same.
3.
Mike's:
y = 100 + 65x = 100 + 65(3) = 100 + 195 = 295
Amy's:
y = 40 + 80x = 40 + 80(3) = 40 + 240 = 280
For 3 hours of labor, Amy's shop is cheaper at $280. Mike's costs $295.
Answer:
1. (4, 360)
2. total cost at both repair shops is the same
3. Amy's Auto Repair: $280
Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}y=100+65x\\y=40+80x\end{cases}[/tex]
Question 1
Solve by using the Substitution Method:
[tex]\implies 40+80x=100+65x[/tex]
[tex]\implies 40+80x-65x=100+65x-65x[/tex]
[tex]\implies 40+15x=100[/tex]
[tex]\implies 40+15x-40=100-40[/tex]
[tex]\implies 15x=60[/tex]
[tex]\implies 15x \div 15=60 \div 15[/tex]
[tex]\implies x=4[/tex]
Substitute the found value of x into one of the equations and solve for y:
[tex]\implies y=40+80(4)[/tex]
[tex]\implies y=40+320[/tex]
[tex]\implies y=360[/tex]
Therefore, the point of intersection is (4, 360)
Question 2
The two lines intersect at (4, 360). This means that the total cost at both repair shops is the same when it takes 4 hours to repair the car. The cost at this time is $360.
Question 2
To find the cost at both repair shops if it takes 3 hours to fix the car, substitute x = 3 into both equations and solve for y:
Mike's Repair shop:
[tex]\implies y=100+65(3)[/tex]
[tex]\implies y=100+195[/tex]
[tex]\implies y=295[/tex]
Amy's Auto Repair:
[tex]\implies y=40+80(3)[/tex]
[tex]\implies y=40+240[/tex]
[tex]\implies y=280[/tex]
Therefore, Amy's Auto Repair company is the cheapest at a cost of $280.

They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.
They are lines that lie exactly on top of one another because they have the same slope and a different y-intercept.
Answers
Answer: C
Step-by-step explanation:
The slope-intercept form of a line is given by
y = mx + b
m - slope
b - y-intercept
Segment AB lies on the line 6x + 3y = 12
6x + 3y = 12
3y = -6x + 12
y = -6/3x + 12/3
y = -2x + 4
Comparing with the slope-intercept form,
Slope = - 2
y-intercept = 4
Segment CD lies on the line 4x + 2y = 8
4x + 2y = 8
2y = -4x + 8
y = -4/2x + 8/2
y = - 2x + 4
Comparing with the slope-intercept form,
Slope = - 2
y-intercept = 4
Both the line segments have the same slope and the same y-intercept, so the two line segments will lie exactly on top of one another.
Therefore, the correct option is (c)
