Group of answer choices
sound; light
sound; electrical
light; sound
electrical; light
Answer:
Sound waves need a medium to travel, but light waves do not.
Step-by-step explanation:
Sound waves need a medium to travel because they cannot travel through a vacuum. This is because sound travels by producing vibration in the molecules of the medium surrounding it and there are virtually no molecules in a vacuum. Light doesn't need a medium through which to travel because the speed of light is experimentally constant.

2. 8.4 X 2.3 X 2.09 = 40.3788
3. $10.04 - $13.47
4. Your friend would be incorrect because their decimal is in the wrong place. Take the decimals out of it and think about it. Can 1 times 2 equal anything near 31? no, so it's not reasonable that your friend could multiply 1.2 X 2.6 and get anything near 31.2
5. It is more reasonable to say between 5 and 6 because even when you round both of the numbers up (3 X 2), you still only get 6.

Did you get a good deal?
Solve this problem in your math notebook, and upload it to the assignment.
Answer: Less, 44 cents
Step-by-step explanation: The new price is 5/4 of a dollar and in decimal form would be 1.25. The old price is 1.69 dollars meaning the new price is a better deal. To find the difference we subtract 1.25 from 1.69 giving us $0.44
Pls help me!! I don’t understand this
Answer:
Step-by-step explanation:
Since the two equations are parralel toeach other they equal each other, so you would solve for:
2x+4=4x-88
To solve this you can add 88 to each side resulting in 2x+92=4x
Then we would add 2x to both sides getting 92=2x
And then you divide both sides by 2, getting 46 degrees for x
(You can check this by plugging points in)
x=46

Which graph represents y as a function of x ?
Answer:
The second one
Step-by-step explanation:
Simply put, in order to be a function the x can not repeat and that is the only graph where they x does not repeat.
Second one graph is represents y as a function of x.
Here four graph shown.
We have to check which graph shows y as a function of x.
What is function?
If for each value of x, there is only one possible value of y or As a graph, if we trace a vertical line; it cannot cross more than one point of the function; then it is called function.
To solve this question we use the definition of function,
In first graph, when we draw vertical line then it intercepts on graph in more than one point, so it does not represents y as a function of x
Similarly, in third and fourth graph we use vertical line test.
Hence, only in second one graph, the vertical line test will be fulfill.
So, Second one graph is represents y as a function of x.

if you reflect any shape across the x-axis and then rotate it 90 degrees clockwise about the origin, do you get the same results as if you reflect it across the y-axis and then rotate it 90 degress counterclockwise about the origin? what does this mean?
Yes, a shape can be reflected across the x-axis and then rotated 90 degrees in a clockwise direction around the origin to achieve the same results as a shape reflected across the y-axis and rotated in a counterclockwise direction. This implies that these two transformational sequences are similar.
What is reflection in Mathematics?A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.
