Answer:

0.1 meters

Step-by-step explanation:

For an electromagnetic wave, the relationship between wavelength λ, frequency ν, and the speed of light c is given by:

c=\lambda \nu

where c=3*10^8m/s.

In our case of the radio waves \nu=3*10^8

therefore the wavelength λ is:

\lambda=\frac{c}{\nu} =\frac{3*10^8}{3*10^9} =0.1m.  

Therefore the wavelength of the radio waves is 0.1 meters.

Anni [7]

Answer:

6 clown fish and 4 angel fish

Step-by-step explanation:

<u>lets say he bought 8 clown fish. </u>

12*8 = 96

the last 4 dollars wont be used.

<u>lets say he bought 7 clown fish-</u>

12*7 = 84

100 - 84 = 16. 16 is not a multiple of 7.

<u>lets say he bought 6 clown fish,</u>

12*6 = 72

100 - 72 = 28

28/7 = 4

If David has $100 dollars to spend and wants to spend every dollar, he can buy 6 clown fish and 4 angel fish.

The value of 33 + 42 = ___.
frez [133]

Answer:

75

Step-by-step explanation:

We line up the tens place of 33 and 42 as well as the ones place so that it looks like:

33

+42

--------

Then we add first the ones, which is 3 + 2 for 5. Then we add the tens together, 3 + 4 is 7. We put the five first since its in the ones place and the 7 second since its in the tens place for 75.

First you need to multiple minus in second bracket, also in other side you need to multiple - 3 in bracket

7t - 2 + 3t - 1 =  - 3 + 9t \\  \\ 10t - 3 =  - 3 + 9t \\ 10t - 9t =  - 3 + 3 \\ t = 0
Final answer is 0
