Answer:
-13.11
Step-by-step explanation:
Remember: Please Excuse My Dear Aunt Sally (PEMDAS)
You use the parentheses first, so it is 18.03-3*(20.76)÷2
So then, you see there are no exponents, so you multiply and divide from left to right. So, 18.03-62.28÷2. Then you divide: 18.03-31.14
Then, you subtract from left to right, which gives you: -13.11

In her science classroom Jane noticed that the lengths (in inches) and the weights (in ounces) of the class's pet snakes were directly related by the equation y = kx, where x is the length and y is the weight. Use the information in the table to find k, the constant of proportionality?A.25.0 B.27.5 C.30.0 D.32.5
Answer:
C
Step-by-step explanation:
multiply by 2 then add half of the original number
The constant of proportionality(k) is 5/2 and the corresponding weight is
30 ounces for 12 inches.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, The lengths (in inches) and the weights (in ounces) of the class's pet snakes were directly related by the equation y = kx.
Now, when x = 6, y = 15
15 = 6k.
k = 15/6.
k = 5/2.
Now, when length(x) is 12 then,
y = 12(5/2).
y = 30.

I don´t know about scale factor so I will also say 5
Answers:
Scale factor = 1/5B = 5===========================================
Explanation:
Look at the left most sides of each figure. Dividing the smaller side over the larger leads to 7/35 = (1*7)/(5*7) = 1/5. This is the scale factor. It means the blue figure's side lengths are 1/5th of the orange figure's corresponding side lengths.
So that explains why your teacher put A = 20(1/5) = 4
Multiplying the orange side lengths by the scale factor gets you the blue side lengths.
Now focus your attention on the far right most side lengths of 25 and B
We can see that B = 25(1/5) = 5 feet.
Which statement correctly describes the expression (-25)(15)?
A. Both factors are negative, so the product will be negative.
B. One factor is positive and one factor is negative, so the product will be positive.
C. One factor is positive and one factor is negative, so the product will be negative.
D. Both factors are negative, so the product will be positive.
Answer:A this is your answer
Step-by-step explanation: hope this helps you
Answer:

The entrance to an accessibility ramp is at ground level.
The first section of the ramp covers a horizontal distance of 18 feet and rises to a landing 1.5 feet above the ground.
The second section of the ramp begins at the landing. It rises at a slope of
\frac{1}{18}
and covers another 9 feet of horizontal distance to reach the door.
Answer the questions to compare the sections of the ramp.
1. What is the slope of the ramp from the ground to the landing? Write your answer as a fraction with a whole-number numerator and denominator.
2. Is the steeper part of the ramp from the ground to the landing or the landing to the door? Explain how you decided which part of the ramp is a steeper.
3. Slope is equal to rise divided by run. If you know the horizontal distance (run) and the slope, how can you find the vertical distance (rise)?
4. What is the vertical distance (rise) from the landing to the door? Show your work.
5. What is the total height of the door above the ground?
Answer: 1.) The slope of the longer ramp is 1/12
2.) The longer ramp from the ground to the landing is steeper. 1/12 is steeper than 1/18. A graph of the slope shows this. See attachment.
3.) If you know the run, you can find the rise by multiplying the run by the slope.
4.) The rise from the landing to the door is 1/2 foot or 6 inches.
5.) The total height of the door above the ground is 2 ft or 24 inches.
Step-by-step explanation: Sometimes it helps to draw a sketch of the info given then make notes as you find solutions. (See in attachments)
1.) 1:5/18. Multiply by 2/2. It becomes 3/36. simplify to 1/12
4.) Multiplying 9ft by 1/18
It's the same as dividing 9÷18= 0.5 ft. OR 9 feet is 108 inches. 108÷18 = 6 inches
5.) Given height, ground to landing: 1.5 ft plus calculated 0.5ft = 2 ft.
OR 18 inches + 6 inches = 24 inches
The answers to questions comparing the sections of the Ramp are;
1) Slope = 1/2
2)The first section of the ramp is steeper because it has a greater slope.
3) Multiply the horizontal distance by the slope.
4) Vertical distance from landing to the door = 0.5 ft
5) Total height of the door above the ground = 2 ft
We are given that;
Height of landing above the ground = 1.5 ft
Horizontal distance of first section of ramp to landing = 18 ft
Horizontal distance of second section of ramp from landing to door = 9 ft
Slope of Second section of ramp = 1/18
I have attached an image showing the ramp alongside the given data;
With these given data, let's proceed to answer the question;
1) Slope is defined as ratio of change in vertical height to change in horizontal distance.From the attached image, we see that for the first section;
vertical height = 9 ft
horizontal distance = 18 ft
Thus, slope = 9/18 = 1/2
2) The slope for the first section is 1/2 = 0.5.The slope for the second section is 1/18 = 0.056
The slope of the first section is greater than that of the second
section and thus we will say the slope of the first section is steeper.
3) Let the vertical distance of the second section from the landing to the door be x.Now, since we know the horizontal distance for this second section as 9 ft and the slope as 1/18, then by proportion, to get the vertical distance (x), we will just multiply the horizontal distance by the slope.
4) Since the vertical distance from landing to the door is labelled as x, then from answer 3 above;x = 9 × (1/18)
x = 1/2 ft
x = 0.5 ft
5) Height of landing above the ground = 1.5 ftHeight from the landing to the door = 0.5 ft
Total distance from ground to the door = 1.5 + 0.5 = 2 ft

Answer:
y=2x-6
Step-by-step explanation:
The slope of a line shows the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
