Answer:
4.08 km
Step-by-step explanation:
we must know what is the speed of sound to determine the distance at which the ray originated
The speed at which the sound of lightning travels is approximately 0.340km/s
then
d = 0.340km/s*12 s= 4.08 km
Answer:
36.48 :)
Step-by-step explanation:
Answer:
s =$10, l = 15, together they are $25
Step-by-step explanation:
Alberto: 1s + 1l = 25
Kali: 3s + 9l = 165
Multiply Alberto x 3: 3s + 3l = 75
Subtract from Kali:
3s + 9l = 165
- 3s + 3l = 75
6l = 90
l = 15, Large = $15.
Substitute into one of the equations: s + l = 25
s + 15 = 25
s = 10
It’s 7 bc diameter is just circumference/pi
