Answer:
15
Step-by-step explanation:
I'J' is IJ with the scale factor of 5.
so (IJ) × 5= (I'J)
(IJ) × 5= 75
75 ÷ 5= 15

On Monday, it snowed 30 inches in 16 hours. On Thursday, it snowed 21 inches in 6 hours. On which day did it snow at a greater rate each hour? How much more per hour?
Answer:
It snowed more on thursday because
Step-by-step explanation:
you just basically divide 30 by 16 30/16 = 1.9 (simplified)
Then you divide 21 by 6 21/6 = 3.5
Answer/ Explanation:
It snowed more on thursday because when you divide 30 by 16 you get 1.9 inches an hour, then I divided 21 by 6 you get 3.5 inches of snow an hour. So therefore on thursday it snowed more every hour.
(I don't care if you use my words for the explanation)
The rate of snow deposition on Thursday is 1.625 inches per hour more than that on Monday.
What is the rate of change?Rate of change is defined as the change in value with rest to the time is called rate of change.
here,
The rate of snow deposition is given as,
Rate = amount of snow/time
On Monday, it snowed 30 inches in 16 hours.
Rate = 30 / 16 = 1.875 inch per hour
On Thursday, it snowed 21 inches in 6 hours.
Rate = 21 / 6 = 3.5 inch per hour
Difference in rate = 3.5 - 1.875
= 1.625 inches per hour
Thus, the rate of snow deposition on Thursday is 1.625 inches per hour more than that on Monday.

Answer:
(6,4) is the answer
The coordinates of the plane to represent the locations of his school and bank are (2, 4) and (6, 4).
What is mean by Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
Mark want to add the location of the library on the coordinate plane.
Since, The coordinates of the plane to represent the locations of his school and bank.

Lucy earns 52 dollars each week working part-time at a bookstore. She earns one additional dollar for each book that she sells.
Let 'A' be the amount (in dollars) that Lucy earns in a week if she sells 'B' books.
Write an equation relating A to B . Then use this equation to find the amount of money Lucy earns if she sells 15 books.
Answer:
A = B + 52
Step-by-step explanation:
A is the total amount each week. 52 is the initial amount that she earns each week. Then, B represents the amount of books she sells. So, 15 books can be represented by
A = 15 + 52 = 67
Answer:
$67 earnings
Step-by-step explanation:
1. Let A = $ earned for books sold
2. Let B = # of books sold
3. Let A = money earned
4. Equation: A = 52 + 1B
5. Solution: $67 = 52+ 1(15)

Step-by-step explanation:
Two students are comparing scientific experiments to investigations. They came up with the following ideas.
Student A: Testing plant growth in different types of soils
Student B: Comparing the water level in a lake during different times of the year Which student gave an example of a scientific experiment? (5 points)
A: Student A because it requires experimental and control groups
B; Student B because it requires a hypothesis
C: Student A because it is preferably done in natural settings
D: Student B because it is preferably done across a long period of time
Answer:
A is the correct answer.
Step-by-step explanation:
In experiment we require a controlled variable which is the constant in example A that is the plant we intend to put into the soil. In example B there's no such thing as controlled variable, so we can't expect the position of the water level. the water level is so unpredictable since tides or tsunami might change the result.
Answer:
A
Step-by-step explanation:
Scientific experiments need to have an independent and a dependent variable. Scientists can manipulate the independent variable. A should be the correct answer because it mentions what I just said. All scientific experiments need to have a control and experimental group. Therefore, student A and the answer A are correct.

Answer:
4(x-1)+9=17
Step-by-step explanation:
3(-2x+1) + 5 = 3x-4-5x
expand
-6x + 3 + 5 = 3x-4-5x
-6x + 8 = -2x - 4
add 2x to both sides to put all x values + coefficients on one side
-4x + 8 = -4
subtract 8 from both sides to isolate x and its coefficient
-4x = -12
divide both sides by -4 to isolate x
x = 3
plug x=3 into each option to see if it works
1. 5(3+3)-4 = 30-4 = 26 != 10
2. 2(3+1) = 8 != 4
3. 4(3-1)+9 = 17 = 17
4. 4(3)+7 = 19 != 3+8 = 11

Use the diagram to find the measure of ∠PML.
Answer:
31 degrees
Step-by-step explanation:
We know that if the angle P is equal to 121+x=180 because when it is reflected, they both have to add up to 180. Therefore, P is equal to 59 degrees. We know that angle L is 90 degrees because there is a square. Therefore, we have to do 180-59-90 to find angle PML. 180-149. Angle PML is equal to 31 degrees.

The graph represents function 1 and the equation represents function 2:
A graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. A horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3.
Function 2
y = 3x + 1
How much more is the rate of change of function 2 than the rate of change of function 1?
1
2
3
4
Answer:
its c
Step-by-step explanation:
Answer:
The rate of change of function 1 = 0 The rate of change of the function 2 = 3
Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.
Hence, option C is true.
Step-by-step explanation:
Function 1
A horizontal straight line is drawn joining the ordered pairs (0, 3) and (4, 3).
Given the points
(0, 3)
(4, 3)
It means
at x = 0, y = 3
at x = 4, y = 3
Since the y-values are same, it means the points lie on a horizontal.
The rate of change or slope of a horizontal line is zero because it does not rise vertically ( i.e. y₁ - y₂ = 0).
Therefore, the rate of change of function 1 = 0
Function 2
y = 3x+1
comparing with the slope-intercept form
y = mx+b
here m is the rate of change or slope and b is the y-intercept
so the rate of change of the function 2 = m = 3
Conclusion:
The rate of change of function 1 = 0
The rate of change of the function 2 = 3
Therefore, the rate of change of function 2 is 3 more than the rate of change of function 1.
Hence, option C is true.

Answer:
Step 1: 4x = -16
Step 2: x = -4

Answer:
- 328 / 9
Step-by-step explanation:
- 36 + ( - 4 / 9 )
= - 36 - ( 4 / 9 )
= - 36 ( 9 / 9 ) - 4 / 9
= ( - 36 x 9 ) / 9 - ( 4 / 9 )
= ( - 324 / 9 ) - ( 4 / 9 )
= ( - 324 - 4 ) / 9
= - 328 / 9
