brainliest is appreciated!
Answer 2

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.

precipitation is moisture that falls as rain or snow. There is a relationship between the depth of rain, r, and the depth of snow, s. Equal quantities of precipitation result in the relationship r/s = 0.1.

r/s = 0.1

Answers

Answer:

I believe the answer would be 1.55

Step-by-step explanation:

Wouldn't you just multiply the amount of snow with 0.1

it would be 1.55cm of rain. you would multiply the 15.5 and the 0.1 to get 1.55

8=f-(13-2)
???? help

Answers

Answer:

I got you

Step-by-step explanation:

f= 19

Simplifying
8 = F + -1(13 + -2)

Combine like terms: 13 + -2 = 11
8 = F + -1(11)

Multiply -1 * 11
8 = F + -11

Reorder the terms:
8 = -11 + F

Solving
8 = -11 + F

Solving for variable 'F'.

Move all terms containing F to the left, all other terms to the right.

Add '-1F' to each side of the equation.
8 + -1F = -11 + F + -1F

Combine like terms: F + -1F = 0
8 + -1F = -11 + 0
8 + -1F = -11

Add '-8' to each side of the equation.
8 + -8 + -1F = -11 + -8

Combine like terms: 8 + -8 = 0
0 + -1F = -11 + -8
-1F = -11 + -8

Combine like terms: -11 + -8 = -19
-1F = -19

Divide each side by '-1'.
F = 19

Simplifying
F = 19

how would you solve -5(x - 1) = 40

Answers

you would distribute the -5 to the x and the -1, so it would be:
-5x+5=40
you would then subtract 5 from both sides, so you would get:
-5x=35
you would then divide by -5 on both sides, so you would get:
x=-7

Answer:

x = -7

Step-by-step explanation:

Apply the distributed property: -5x - -5 = 40Simplify: -5x + 5 = 40Subtract 5 from each side, so it now looks like this: -5x = 35Divide each side by -5 to cancel out the -5 next to x. It should now look like this: x = -7

Elena has some bottles of water that each holds 17 fluid ounces. A. Write an equation that relates the number of bottles of water (x) to the total volume of water (y)in fluid ounces. B. How much water is in 51 bottles? C. How many bottles does it take to hold 51 fluid ounces of water?

Answers

Answer:

17b

Step-by-step explanation:

Total volume of water = amount of water in each bottle x total number of bottles. The equation that relates the number of bottle of water (b) to the total volume of the water (w) in fluid ounces is w = 17b

Answer:

A. y = 17x

B. 867 fluid ounces

C. 3 bottles

Step-by-step explanation:

There are few bottles of water that each contain 17 fluid ounces of water.

A. If the number of bottles is given by x and the total volume of water those bottles contain is y in fluid ounces, then the equation that relates x and y is  

y = 17x ...... (1) (Answer)

B. If x =51, then the volume of water in 51 bottles will be given by equation (1) as  

y = 51 × 17 = 867 fluid ounces. (Answer)

C. If y = 51 fluid ounces, then from equation (1), the number of bottles will be given by x = 51/17 =3 bottles. (Answer)
