<h2>
The stone fall in air for 7 seconds and fall in water for 5 seconds.</h2>
Step-by-step explanation:
Total distance to sea bed = 127 m
Let the distance traveled in air be s.
Distance traveled in water = 127 - s
Average velocity in air = 16 m/s
Average velocity in water = 3 m/s
Distance traveled in air = Average velocity in air x Time in air
s = 16 x t₁
Distance traveled in water = Average velocity in water x Time in water
127-s = 3 x t₂
We have total time is 12 seconds
That is
t₁ + t₂ = 12
We have
s = 16 x t₁
112 = 16 x t₁
t₁ = 7 s
t₁ + t₂ = 12
7 + t₂ = 12
t₂ = 5 s
The stone fall in air for 7 seconds and fall in water for 5 seconds.
Answer:
I believe the answer would be 44cm for the whole perimeter. I hope this helps some what.
Answer:
square
Step-by-step explanation:
x values are -6 and 4, so their distance is 10 units.
y values are -5 and 5, so their distance is also 10 units.
4 lines with equal length creates a square.
Solution for the question asked: 3x^2-5x+4=6
it can be simplified by subtracting 6 from both the sides...
3x^2-5x+4-6=6-6
3x^2-5x-2=0 which is the required form where a=3,b=-5 and c=-2.Now putting the values in the formula we will get two values for x which are 6 and (-1).
hope this will help you
Answer: 754
Step-by-step explanation:
Divide 683/11 to get the unit rate of 58. That means she is driving 58mph.
Multiply that by how many hours you have, 13, and you get 754.
