Answer:
x=9.5 and y=15.3
Step-by-step explanation:
to find x you do sine of 32 = x/18 because the sine is opposite/hypotenuse
you put in a calculator sine (32) x 18 and get 9.538546756
so x equals 9.538546756 but it says to round to the nearest tenth so x equals 9.5
to find y you do the cosine of 32 = y/18 because cosine is adjacent/hypotenuse
cosine of (32) x 18 = 15.26486573 so you equals 15.26486573 but since you have to round to the nearest tenth y = 15.3
The answer: c. 24
1/2 x 24 = 12
Answer:
1 - First question = 6.00 | Second Question = 0.06
2 - Didnt know
3 - 1360, from 1.36kg
4 - 0.3175
5 - 20.5
6 - 18
7 - 965606.4
Step-by-step explanation:
sorry I couldn't give you number 2, but here are the rest of the answers
1. 2*3*3 = 18 different combinations.
2. P(3 or even) = P(3) + P(even)
1/6 + 3/6 = 4/6 = 2/3
3. Rolling an odd or even number on a number cube.
<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>
