Answer:
4 × 10^2 M
Step-by-step explanation:
We are given;
Speed of light as 3.0 × 10^8 m/s
Frequency of radio wave as 7.5 × 10^5 Hz
We are required to determine the wavelength.
Using the formula;
wavelength, λ = v/f
Note; Radio wave is an electromagnetic wave, therefore travels with the speed of light.
Therefore;
wavelength, λ = 3.0 × 10^8 m/s ÷ 7.5 × 10^5 Hz
= 4 × 10^2 M
Hence, the wavelength of the radio wave is 4 × 10^2 M
Answer:
The answer is 5
Step-by-step explanation:
Lets start of by getting to 0, that distance is 3.25, and the additionally we have to add the 1.75, making us get an answer of 5.
Answer:
54 and 42
Step-by-step explanation:
add 9 and 7
use your answer as a denominator
to find the value for 9 you do 9/16 *96
which will give you 54
then do the same for 7 but replace the 9 with seven

Answer:
6 children
Step-by-step explanation:
If all of the group were adults, the total cost of tickets would be 8×$10 = $80. The actual cost was $80 -62 = $18 less than that. Since each children's ticket saves $3 off the cost of an adult ticket, there were $18/$3 = 6 children's tickets.
There were 6 children in the group.
_____
If you want an equation, you can let c represent the number of children. Then the cost of tickets is ...
8(10 -c) +5c = 62 . . . . 10-c is the number of adults
-3c = -18 . . . . . . . subtract 80
c = -18/-3 = 6 . . . divide by 3

Answer:
354,998
Step-by-step explanation:
If the number is less than 350,000, it will not round to 400,000.
If the number is 355,000 or more, it will not round to 350,000.
The number (n) must satisfy ...
350,000 ≤ n < 355,000
__
If we're restricted to integers, the number could be any between 350,000 and 354,999, inclusive. One possibility is 354,998.
