<span>The speed is 57.5 m/s and the parachutist will fall 1150 m in 20 seconds.
Explanation<span>:
We start out with the ratio 207 km/1 hr.
We know that 1 km = 1000 m; this means 207 km = 207*1000 = 207000 m. This gives us 207000 m/1 hr.
We know that 1 hr = 60 minutes, so we have 207000 m/60 min.
We also know that 1 min = 60 seconds, so 60 min = 60*60 = 3600 sec; this gives us 207000 m/3600 sec.
Dividing this, we get 57.5 m/s.
In 20 seconds, the parachutist will fall 57.5(20) = 1150 m.</span></span>
Slope = change in y / change in x
slope = (6-3) / (8-2)
Slope = 3/6
slope = 1/2
Answer:
60%
Step-by-step explanation:
8 is 40% of 20, therefore the girls would make up 60% percent of the class.
Step-by-step explanation:
I4(-3)+5| +8(-3)
|-12+5| -24
7-24 = -17
0.25kgx9.81 then u will get the ans.
