Radio waves travel at the speed of light, 3.0 × 108 m/s. What is the wavelength of a radio wave from an AM station broadcasting
pochemuha

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

What is -4x+3=-16j-5​
igomit [66]

Answer:

1/4x + -1/2

Step-by-step explanation:

Step 1 :

-4x - 3 = -16j -5

Step 2:

-16j − 5=−4x+3

Step 3:

−16j−5+5=−4x+3+5

−16j=−4x+8

Step 3:

-16j/-16 = -4x + 8/-16

Answer:

j = 1/4x + -1/2

Discount tickets to a basketball tournament sell for $4.00 each. Enrico spent $60.00 on discount tickets, $37.50 less than if he
Paraphin [41]

Option C : $6.50 is the right answer

Step-by-step explanation:

Given

Price of one discounted ticket = $4.00

Total amount spent on discounted tickets = $60.00

So,

Total\  tickets = \frac[Total\ price}{Price\ of\ one\ ticket}\\=\frac{60}{4}\\= 15\ tickets

Hence he bought 15 tickets

Now,

If he had bought without discount he would have paid $37.50 so

Total price without discount will be: $60.00 + $37.50 = $97.50

So,

Price of one ticket before discount:

\frac{Total\ price\ without\ discount}{Total\ tickets}\\=\frac{97.50}{15}\\=6.5\ dollars

Hence,

Option C : $6.50 is the right answer

Write the following as an inequality.
Dimas [21]
Answer:
-9 < w ≤ 5

Explanation:
W is bigger than -9 so the symbol has the bigger end towards the W.
W is also less than or equal to 5 so the smaller end of the sign is towards the W.
