Susan is having a debate with her brother about wave
movement. She believes waves will always travel the same
speed if they have the same energy, no matter what the
medium it is traveling through. Her brother says this is not
correct, and different mediums lead to different wave
speeds. Who is right and why?

Answer:

x=0

Step-by-step explanation:

The parenthesis mean that it's multiplication, so it might be easier to convert that to: 5 · x = 0. We then know that anything times zero equals zero, so 5 · 0 = 0! I hope this helps! :)

Answer:

Conversion factors are easier to use because they are constant.

For example, if you needed to convert, say, 13 kilometers to feet, a conversion factor would help. You would use proportions to convert given a similar conversion.

Essentially, you're answer is correct, because one way to convert units may be different than somebody else's. For you, might be using proportions, which is fine.

25 hours, charge= 800

Step-by-step explanation:

300 + 20x = 500 + 12x

8x = 200

x = 25

300 + 20(25)

300+500 = 800

500 + 12(25)

500 + 300 = 800

Answer:

The equation of the line is;

y = 3x + 18

Step-by-step explanation:

We want to write the equation of the line through (-9,-9) and (-6,0)

we start by calculating the slope of the line

m = (y2-y1)/(x2-x1) = (0+ 9)/(-6+9) = 9/3 = 3

The general equation of the line is;

y = mx + c

y = 3x + c

To get c, we use any of the points

we substitute for example -6 for x and 0 for y

0 = 3(-6) + c

c = 0 + 18 = 18

So the equation of the line is;

y = 3x + 18

Answer:

3x+18

Answer:

7 [tex]\frac{1}{2}[/tex] miles

Step-by-step explanation:

The problem above is under the topic, "Subtracting Mixed Numbers with Similar Fractions."

In order to find the answer, you have to subtract the whole number parts first.

12-5 = 7

Then, you have to subtract the fractional parts. All you have to do is to get the difference of the numerators and copy the denominator.

7/8 - 3/8 = [tex]\frac{4}{8}[/tex]

Therefore, 12 [tex]\frac{7}{8}[/tex] - 5 [tex]\frac{3}{8}[/tex] = 7 [tex]\frac{4}{8}[/tex] miles

Let's simplify: 7 [tex]\frac{1}{2}[/tex] miles

Answer:

Step-by-step explanation:

y=5x-2

slope of the line is 5 because if we compare to

y=mx+b where m is the slope we see m=5

Points (0,-2), (2,8), (4,18)

slope between the points (0,-2), (2,8)

m=(y2-y1)/(x2-x1) = -2-8/0-2 = -10/-2 = 5

slope between the points (4,18), (2,8)

m=(y2-y1)/(x2-x1) = 18-8/4-2 = 10/2=5

slope between the points (4,18), (0,-2)

m=(y2-y1)/(x2-x1) = 18+2/4-0= 20/4 =5

Answer:

Your answer is 61.

Step-by-step explanation:

43+[(96÷8) × 5]-42, first you have to divide 96 and 8.

96 divided by 8 is 12. next you multiply 12 and 5. 12 multiplied by 5 equals 60. then you take 60 and add the 43. you will get 103, then you take 103 and subtract 42, and you will get 61.

Example:

43 + [(96 ÷ 8) × 5] - 42

43 + [12 × 5] - 42

43 + 60 - 42

103 - 42

Answer:

The answer is 29

Step-by-step explanation:

We want to see which pair of triangles is equivalent by the Angle-Angle-Side criteria.

The correct option is 2, where we have two equal angles, and the bottom side is equal in both triangles.

The Angle-Angle-Side criteria means that if two triangles have an equal side, and the two correspondent angles also are equal, then these triangles are equivalent.

So we just need to see (by notation, not by how the triangles look like) in which ones we have two equal angles and one equal side.

That one is the second pair of triangles.

We can see that the two top angles are equal (two curves) and that the left angle in the left triangle is equal to the right angle on the other triangle (so we have two equal angles).

Also, the bottom side is equal on both triangles.

Then the angle-angle-side criteria is meet, meaning that these two triangles are equivalent.
