<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>
Since there is 12 students who prefer rock and 4 that prefer classic rock that will equal 16. add up all the other number to get 26 and your ratio will be: 16/26
Answer:18x cubed +8x squared
Step-by-step explanation:
G+b=5716
65g+40b=341690
multiply first equation by -65
-65g-65b=371540
add that to 2nd equation
-65g-65b=-371540
<span><u>65g+40b=341690 +</u></span><u />
0g-25b=-29850
-25b=-29850
divide both sides by -25
b=1194
latter=bleacher=1194 tickets
Answer:
48/37 + (8/37)i.
Step-by-step explanation:
8 / (6 - i)
We multiply top and bottom of the fraction by the conjugate of 6 - i , which is 6 + [email protected]
= 8*(6 + i) / (6 - i)(6 + i)
= 48 + 8i / (36 + 6i - 6i - i^2)
= 48 + 8i / (36 - (-1))
= 48 + 8i / 37
= 48/37 + (8/37)i.
