The answer is <span>0.118 seconds</span>.
The velocity (v) is the distance (d) divided by time (t):
v = d ÷ t
It is given:
v = 3.00 × 10⁸ meters per second
d = 3.54 × 10⁷ meters
It is unknown:
t = ?
If:
<span>v = d ÷ t
</span>Then:
<span>t = d ÷ v
</span>t = 3.54 × 10⁷ meters ÷ <span>3.00 × 10⁸ meters/second
t = 1.18 </span>× 10⁻¹ seconds
t = 0.118 seconds
Therefore, radio signal will travel from a satellite to the surface ofEarth 0.118 seconds.
Answer:
Joey needs to eat 7 hot dogs per minute to break his own record in next 9 minutes.
Step-by-step explanation:
Joey needs more than 72 hot dogs in 10 minutes to break his own record.That means Joey needs to eat at least 73 hot dogs in 10 minutes.
After 1 minute Joey has eaten = 10 hot dogs.
In remaining 9 minutes balance hot dogs = 73-10 =63
Therefore per minute hot dogs to be eaten = 63/9 =7
So answer is 7 hot dogs per minute to be eaten.
Answer:
7
Step-by-step explanation:
h=hat
t= t-shirt
60-21=$39
39=3h
39/3=13 per one hat
21=3t
21/3=7= 7$ per one shirt
Answer:
x = 9
Step-by-step explanation:
I think you wrote the question wrong (I am assuming that there is a x next to the -3).
Subtract 7
-27 = -3x
divide by -3
9 = x
Let x be the unknown number
2x +7 = 39
2x+7-7 = 39-7
2x = 32
2x/2 = 32/2
x=16
You use the balance method to solve. First, you cancel the +7 by subtracting the 7 ON BOTH SIDES to balance the equation.. After that, you are left with 2x, where you will need to isolate the x by dividing by 2 ON BOTH SIDES to balance it.
Hope this helps
