Jake earns $8 per hour for cutting grass. If he works a 35-hour week,
how much money will he earn?
There are many ways to solve these types of questions. But I am going to use the fraction method.
Step 1: Set up a fraction.
Setting up a fraction, given the question will be the units on the same level. And the money earned will be a variable, "[tex]m[/tex]". It does not matter whether they are top or bottom.
[tex]\frac{8}{1} = \frac{m}{35}[/tex]
Step 2: Solve
[tex]\frac{8}{1} = \frac{m}{35}[/tex]
Multiply 35 to both sides[tex]\frac{35m}{35}=8\cdot \:35[/tex]
[tex]m=280[/tex]
Therefore, Jake will earn $280.

In the figure shown, line AB is parallel to line CD.
Part A: What is the measure of angle x? Show your work. (5 points)
Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)
Answer:
x=53
Step-by-step explanation:
Parallel lines cut by a transversal mean that the alternate interior angles are congruent. Meaning, 115=62+x
115-62 is 53
Answer:
a) x=56º
b= Angle x is on a line. All lines create linear angles, so together all angles that are on that side of the line = 180º. Since the two lines were parallel we know that the two angle measurements next to x are congruent. So 180=62+62+x.
Step-by-step explanation:
180-62-62=56
What is the answer for x?
Answer:
B
Step-by-step explanation:
Not sure if this correct but hope it helps
Answer:
C
Step-by-step explanation:
Exterior angle property: Exterior angle equal the sum of opposite interior angles.
3x + 7 + 4x + 16 = 100
3x + 4x + 7 + 16 = 100 {Combine like terms}
7x + 23 = 100 {Subtract 23 from both sides}
7x = 100 - 23
7x = 77 {Divide both sides by 7}
x = 77/7
x = 11
∠B = 3x + 7 = 3*11 + 7
= 33 + 7

Original grade:80
New grade:100
Find the precent of increase
Answer:
25%
Step-by-step explanation:
because from 80 to 100 is 20 and 20 is 1/4 of 80 and 1/4 to a decimal is .25
Answer:
80/100. That's 20% increase. When you hadd 8 and 2 you get 10.

Which one of the following would most likely have a positive linear correlation coefficient?
A. grade point average compared to the number of hours a student watches TV
B. the height of a tomato plant throughout the year
C. a person's salary compared to the amount of education they have attempted
D. SAT scores compared to hours spent studying
Answer: B
Step-by-step explanation: The tomato grows more over time so it will be a positive..
The height of a tomato plant throughout the year shows a positive linear correlation coefficient option (B) is correct.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
A. grade point average compared to the number of hours a student watches TV.
The grade points depend on the number of hours a student watches TV.
If watching time increases the grade point decreases.
B. the height of a tomato plant throughout the year
The height of a tomato and the number of years show a positive linear correlation.
C. a person's salary compared to the amount of education they have attempted:
The above situation represents an exponential regression.
D. SAT scores compared to hours spent studying
If the time spent in studying increases the SAT scores increases rapidly.
Thus, the height of a tomato plant throughout the year shows a positive linear correlation coefficient option (B) is correct.

421 divide by 27 with remadire help
Answer:
Therefore, the answer to 421 divided by 27 calculated using Long Division is:
15
16 Remainder
Step-by-step explanation:
421 = dividend
27 = divisor
Step 1:
Start by setting it up with the divisor 27 on the left side and the dividend 421 on the right side like this:
2 7 ⟌ 4 2 1
Step 2:
The divisor (27) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:
0
2 7 ⟌ 4 2 1
Step 3:
Multiply the divisor by the result in the previous step (27 x 0 = 0) and write that answer below the dividend.
0
2 7 ⟌ 4 2 1
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.
0
2 7 ⟌ 4 2 1
- 0
4
Step 5:
Move down the 2nd digit of the dividend (2) like this:
0
2 7 ⟌ 4 2 1
- 0
4 2
Step 6:
The divisor (27) goes into the bottom number (42), 1 time(s). Therefore, put 1 on top:
0 1
2 7 ⟌ 4 2 1
- 0
4 2
Step 7:
Multiply the divisor by the result in the previous step (27 x 1 = 27) and write that answer at the bottom:
0 1
2 7 ⟌ 4 2 1
- 0
4 2
2 7
Step 8:
Subtract the result in the previous step from the number written above it. (42 - 27 = 15) and write the answer at the bottom.
0 1
2 7 ⟌ 4 2 1
- 0
4 2
- 2 7
1 5
Step 9:
Move down the last digit of the dividend (1) like this:
0 1
2 7 ⟌ 4 2 1
- 0
4 2
- 2 7
1 5 1
Step 10:
The divisor (27) goes into the bottom number (151), 5 time(s). Therefore put 5 on top:
0 1 5
2 7 ⟌ 4 2 1
- 0
4 2
- 2 7
1 5 1
Step 11:
Multiply the divisor by the result in the previous step (27 x 5 = 135) and write the answer at the bottom:
0 1 5
2 7 ⟌ 4 2 1
- 0
4 2
- 2 7
1 5 1
1 3 5
Step 12:
Subtract the result in the previous step from the number written above it. (151 - 135 = 16) and write the answer at the bottom.
0 1 5
2 7 ⟌ 4 2 1
- 0
4 2
- 2 7
1 5 1
- 1 3 5
1 6
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 421 divided by 27 calculated using Long Division is:
15
16 Remainder
More Information
If you enter 421 divided by 27 into a calculator, you will get:

1. The sum of the real numbers x and y is 15. Their
difference is 3. What is the value of xy ?
A. 3
B. 6
C. 9
D. 15
E. 54
( I really need this to be worked out so may I have help with this?)
Answer:
x = 9
y = 6
Step-by-step explanation:
Let's set up equations:
x + y = 15
x - y = 3
Let's rearrange one of these equations to use the substitution method:
x - y = 3
Add y to each side:
x = y + 3
Substitute in for x:
x + y = 15
y + 3 + y = 15
Combine like terms:
( y + y ) + 3 = 15
2y + 3 = 15
Subtract 3 from each side:
2y = 12
Divide each side by 2:
y = 6
Substitute this in to find the other variable:
x + y = 15
x + 6 = 15
Subtract 6 from each side:
x = 9
Mr. Marlon pays minimum wage to the cashiers in his store. If minimum wage is $7.25 per hour, how much does a cashier make who works 40 hours per week?
======================================================
Explanation:
We multiply the hourly wage by the number of hours worked to get the total amount earned.
(7.25)*(40) = 290
This is before taxes are applied. So we consider it the gross earnings (as opposed to the net earnings).

Go to your math tools and open the Graph tool to graph the equation you found for calculating profit. Set the scale of the graph to go from -5 to 40 on the x-axis and from -80 to 80 on the y-axis.
Part A
What do the points on the line in quadrant IV represent in terms of the situation?
Answer:
The y-coordinates in quadrant IV are negative. Because y represents profit, negative values of y signify not making a profit. That is, negative values signify loss. The points in quadrant IV represent the baseball team losing money.

Find the average speed in km/h for a journey of 175 meters and 35 seconds
Answer:
18 km/h
Step-by-step explanation:
1. Convert 175 metres into km
1000 m = 1 km (divide by 1000)
175 ÷ 1000 = 0.175 km
so 175 m = 0.175 km
2. Convert 35 seconds into hours
60 seconds = 1 min
60 mins = 1 hour
3600 (60 × 60) seconds = 1 hour (divide by 3600)
35 ÷ 3600 = 0.00972...
3. Calculate the speed
speed = distance ÷ time
= 0.175 ÷ 0.00972...
= 18 km/h
