12^2 +b^2 = 20^2 because of the Pythagorean theorem
144 + b^2 =400
B^2 =256
B=16
a) 32.25* 40 = 1290
b) 32.25 (1.5) *12 =580.50
c) 1290+580.50=1870.50

Answer:
6.1 seconds
Step-by-step explanation:
<u><em>The correct question is</em></u>
A helicopter flying at an altitude of 600 ft dropped a package to a lifeboat. Use the formula t= √h/4 to find how many seconds it takes for the package to reach the lifeboat. Round your answer to the nearest tenth of a second
we have
![t= \frac{\sqrt{h}}{4}](https://tex.z-dn.net/?f=t%3D%20%5Cfrac%7B%5Csqrt%7Bh%7D%7D%7B4%7D)
substitute the value of h in the formula
![h=600\ ft](https://tex.z-dn.net/?f=h%3D600%5C%20ft)
![t= \frac{\sqrt{600}}{4}=6.1\ sec](https://tex.z-dn.net/?f=t%3D%20%5Cfrac%7B%5Csqrt%7B600%7D%7D%7B4%7D%3D6.1%5C%20sec)
Answer:
21.74 But if it tells you to round I would round to 21 lbs
Step-by-step explanation:
its basically just a ratio of 92 to 20
92/20=4.6
92-20=72% the amount that is lost
so given that the plum is 100 lbs we know that 72% is depleted
(72/92 = .78)X100= 78 lbs depleted
Lastly 100-78 =22 for the remaining weight of the prunes.
