Casey wants to determine whether the rate at which melted glass cools affects the strength of the glass. He pours melted glass into a form and cools the glass at different rates. Then, he tests the breaking strength of each form. Which of the following is the test variable in this experiment?
A. type of glass
B. strength of the glass
C. thickness of the glass
D. cooling rate of glass
Help if you know and are sure!
D
"What is a variable?
A variable is used in a Fair Test. A variable is any one of the elements of the test which could be changed. They can change the outcome of an experiment.
In a fair test, only one variable is allowed to be manipulated – all others have to be kept the same,or “controlled”."
Miss Owens has a coupon for 40% off a pair of shoes she pays $111.79 for a pair of shoes and a dress after using the coupon. The dress costs $64.99. Which equation can be solved for x, the retail price of the shoes?
Answer:
The answer is A.
Step-by-step explanation:
Process of elimination... Its not C or D because the % distributes onto the dress cost and it only contributes to 111.79. Also, 40% of 1 is 0.6 so its not B, which leaves A...

A right triangle has a vertex at point B, a height of 6 units, and a base of 4 units.
Use the Polygon tool to draw the triangle.
Each segment on the grid represents 1 unit.
Answer:
From the Vertex B, draw a line segment up 6 units or 6 boxes and then from the same Vertex B, draw a line going either left or right 4 units. Then connect everything together it will form a right triangle.

The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes:
Part A: Describe how you can use similar triangles to explain why the slope of the graph between points A and B is the same as the slope of the graph between points A and C.
Part B: What are the initial value and slope of the graph and what do they represent?
Step-by-step explanation:The slope of AB and BC are the same.
The initial value is 60 m and the slope is 40 m/min.
Step-by-step explanation:
The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes.
See the graph attached.
Part A : If we consider two right triangles one Δ ABD and Δ BCE, where D(2,100) and E(1,60) points.
Now, those two triangles are similar and hence the slope of line segment AB will be .
Again, the slope of the line segment BC will be
Hence, and the slope of AB and BC are the same. (Answer)
Part B : From the graph, it is clear that the initial value of the graph is 60 m and it represents that initial position of the shark i.e. at t = 0 min, the shark was at a depth of 60 m from the water surface.
The slope of the graph is 40 means the rate of change of distance from the Ocean surface of the shark with respect to time in minutes will be 40 m per min. (Answer)

PLZZZ help with this its pretty simple!
Answer:
It should be D, [tex]x^4 - 2x^3 + 7x^2 -12x - 4[/tex]
Step-by-step explanation:
Since, the equation given in the question is the factored form of the equation D. It can be solved using FOIL (First Outside Inside Last):
x * x³ = [tex]x^{4[/tex]
x * 7x = 7x²
x * 2 = 2x
-2 * x³ = -2x³
-2 * 7x = -14x
-2 * 2 = -4
This all would add up to ⇒ [tex]x^{4}[/tex] - 2x³ + 7x² + (-14x + 2x) -4
Simplifying the parenthesis further would give the option D as the answer.

Step-by-step explanation/ Answers
because you have 5% possibilities and a total of 100%. You divide
100 by 5 and then you get 20 so that is for question 5
for question 6 it would be 80 because 100 - 20 is 80
for question 7 it will be 40 because 20 + 20 is 40

Answer:
A, B, C, E, and F
To solve this problem, you should make sure to find the equation first. Start by doing rise/run with your two given points on the graph. From the point (-1,1) you rise 4 and then run 16 over to the point (3,2). That gives us a slope of 4/16 which can then be simplified to 1/4. That means that letter F tells us the equation of the line is y= 1/4x + 5/4.
From there you want to check your points, (3,2) and (-1,1). The first number is always x and the second number is always y. So you plug the point numbers into the equation we just found to see if they work. In the photos I inserted are how to do this step.
Once you have checked your points and you know for sure they're solutions, that gave you letters A and B. Since the point (1, 3/2) is also given in one of the answers we should check that point as well. (Also done in one of the photos) Since the point came out correctly that gives us letter C and also tells us there is more than 2 solutions. This means that letter E is also correct.
Hope this helped!
