Answer:

y = (3 × 10^8 m/s)/x

Step-by-step explanation:

Speed of a wave is given by the product of wavelength and frequency.

Thus; speed = frequency × wavelength

If  x = wavelength and y = frequency then speed will be;

speed = yx

Thus to get wavelength, y;

y = speed/x , but speed is 3 × 10^8 m/s

Thus;

y = (3 × 10^8 m/s)/x

What is the next number and why ? 1,3,11,35,99,_
Vladimir79 [104]

Answer: 241

Step-by-step explanation:

This is a simple problem when using Pascal's triangle. First you look at 1 - 3, what is the difference in these 2 numbers? Its 2, then you look at 3 and 11, the difference is 8, then 11 and 35, the difference is 24. If you keep doing this you get; 2 8 24 64 142. Next you find out how these numbers are different. In the end you keep doing this until you get to the triangles point or the differences converge.

                                          1      3      11      35     99      <u>241</u>

                                             2      8     24       64    142

                                                6      16      40      78

                                                     10     24      38

                                                          14       14

In the end we get 14 but there is no difference in the numbers so we cant go any farther. Hope this helps!

700 miles the train takes 5 hours to a travel the distance at what unit rate is the train traveling?
dalvyx [7]

Answer:

The rate is 140 miles per hour

Step-by-step explanation:

We can use the formula distance is equal to rate times time

The distance is 700 miles and the time is 5 hours

D =rt

700 = r*5

Divide each side by 5

700/5 = 5r/5

140 =r

The rate is 140 miles per hour
