Triangle HIJ is dilated by a scale factor of 5 to form triangle H'I'J'. Side I'J' measures 75. What is the measure of side IJ?
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
I am so sorry i did the math wrong in my head, the answer is 15 not 16.

Answer:
D
Step-by-step explanation:
Pythagorean Theorem: a^2+b^2=c^2
6^2+10^2=c^2
36+100=136(radical symbol)
Answer is D
Hope this helps :)
Answer: hope this helps ♡
D) √136 ft.
Step-by-step explanation:
c = hypotenuse
a & b = the two other sides
a² + b² = c²
6² + 10² = c²
36 + 100 = c²
136 = c²
(11.6 = c)

Find the measure of angle 3.
A. 15 degrees
B. 45 degrees
C. 30 degrees
D. 60 degrees
Answer:
45°
Step-by-step explanation:
Well, compared to 90°, it looks like it's just smaller, but not too small. It couldn't be 15° degrees, or 60°, as it was probably too much. I Don't think it's 30° either, because it looked bigger than what a 30° angle would be.
Hope it helped!

Micah and Lucy are in the school play.
Micah memorizes 12 lines of the script the first day and 10 lines each day after that.
Lucy memorizes 8 lines of script the first day and 12 lines each day after that.
What ordered pair represents the total number of lines they have memorized after 5 days?
(12, 8)
(40, 48)
(50, 60)
(52, 56)
Answer:(50,60)
Micah: 10 lines for 5 days; 10 x 5= 50
Lucy: 12 lines for 5 days; 12 x 5= 60
Your answer would be (50,60)

Select all ratios equivalent to 30:14 A. 6:4 B. 21:7 C. 60:28
Answer:
c
Step-by-step explanation:
30:14 The division isn’t proportional. 30/5 is 6 but 14/5 is not 4.
6.4
—————
30:14 Same here as above just now the 14 is proportional just not the 21.
21:7
—————
30:14 Finally! The 2nd ratio is twice the first!
60:28
Answer: hope this helps ♡
C. 60:28
Step-by-step explanation:
30:14
A. 6:4 → 30 ÷ 6 = 5 & 14 ÷ 4 = 3.5 (the answers aren't equal) 30:14 ≠ 6:4
B. 21:7 → 30 ÷ 21 = 1.4 & 14 ÷ 7 = 2 (the answers aren't equal) 30:14 ≠ 6:4
C. 60:28 → 30÷60 =0.5 & 14÷28 = 0.5 (the answers are equal) 30:14 = 60:28
I dont understand this at all, can someone give an explanation for brainliest?
Answer:
The area of a parallelogram is base x height. You multiply the base and height (represented as b and h) to get the area of the parallelogram.
In the first question, the base and height is already given to you so, 2x6=12.
12yd squared is the area for the first one.
Now lets do the second one. The base and height is also given to you so do, 6x4=24.
24m squared is the area of the second one.

the cost of 4 pounds of potatoes is 3.56. what is the constant of proportionality that relates the cost in dollars, y to the number of pounds of potatoes, x
what is the answer? please help
Answer:
0.89
Step-by-step explanation:
y = kx
3.56 = k(4)
Divide both sides by 4
k = 0.89
Answer:
0.89
Step-by-step explanation:
Divide 3.56 by 4 to get the constant of proportionality
3.56 divided by 4 equals 0.89.

Nancy lives in a state where sales tax is 9%. This means you can find the total cost of an item, including tax, by using the expression c + 0.09c, where c is the pre-tax price of the item.
Use the expression to find the total cost of an item that has a pre-tax price of $84.00.
Answer:
91.56
Step-by-step explanation:
84 x 0.09=7.56

HELP ME PLEASE !!!!!!!!
Answer:
Step-by-step explanation:
To think about this logically, lets take a different, more simplified example.
Lets say we have two numbers: 4 and 6
The product of these numbers is 24. If we doubled the product, we would get 48.
Using our original equation, how could we get a result of 48? We could double either 4, or 6. 8 times 6 equals 48, and 12 times 4 equals 48.
So, from this we can take away that in an expression, doubling one number will double the answer. On a side note, you could you use this not only when doubling a number. If you tripled a number in an expression, then the answer to the expression would also triple.
So, the answer to your question is (A) - Double one dimension

What is the area of this figure?
Answer:
16+110=126 m²
Hope it helps :)
Answer:
Area of 1 st rectangle, length = 10m and breath = 15m
So using formula , rectangle = length × breadth
= 10 m × 15 m
=150^{2}
again,
Area of 2 st rectangle, length = 6m and breath = 4m
So using formula , rectangle = length × breadth
= 6 m × 4 m
= 24m^{2}
Now ,
Final area of whole box = 1^{st} area - 2^{nd} area
= 150m^{2} - 24m^{2}
= 126 m^{2} is answer
Find the value of the variable.
These angles are supplementary, meaning that their sum should be 180.
Write an equation.
5x+110=180
5x+110-110=180-110
5x=70
x=14
To find the angle measure,
multiply 5 by 14.
5 x 14= 70
To check:
70+110=180
Therefore, the variable has a value of 14.
Describe the pros and the cons of using the standard form of a line to graph an equation.
Answer:
The standard form of a line is expressed as Ax + By = C, where A, B, and C are constants and x and y represent the variables. One advantage of using the standard form to graph a line is that it is relatively easy to determine the slope and y-intercept of the line from the constants A and B. This can be particularly useful when trying to analyze the behavior of the line.
Another advantage of using the standard form is that it allows you to easily determine the equation of the line when given a set of points. For example, if you are given the points (2,4) and (3,6), you can use the standard form to find the equation of the line that passes through these points by substituting the coordinates into the form and solving for the constants.
One potential disadvantage of using the standard form is that it can be more difficult to interpret the meaning of the constants A, B, and C in terms of the context of the problem. For example, if the line represents the cost of a product, it may be more intuitive to express the equation in terms of the variables x (the number of units) and y (the cost). In this case, it may be more useful to use the slope-intercept form of the equation, which is expressed as y = mx + b, where m is the slope and b is the y-intercept.

I have part 1 done I just need help with part 2 and 3
Part 1
You will need to measure five different people. Record your measurements on a piece of paper. Using a tape measure or ruler, measure the length (in inches) of a person’s left foot and then measure the length (in inches) of that same person’s forearm (between their wrist and elbow). Refer to the diagrams below. You will have two measurements for each person.
(An easy way to measure the length of a foot is to have your subject stand on a piece of paper. Then, trace their foot and measure the outline once they move off the paper.)
To measure the forearm, measure inside the arm, between the wrist and the elbow.
forearm(in) foot (in)
8 10
11 12
14 14
15 16
15 17
Part 2
Organize your data and find the rate of change.
Create a table of the measurements for your data. Label the forearm measurements as your input and the foot measurements as your output.
Select two sets of points and find the rate of change for your data.
Describe your results. If you had to express this relation as a verbal statement, how would you describe it?
Part 3
Compare rates of change.
The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
What is the rate of change of the equation from Part A?
Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?
Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.
For this option you will submit the details from all three parts. Submit your measurements, the table, and description that you created in Parts 1 and 2. Submit your answers to the questions from Part 3.
Answer: You'll be able to do this!
