Answer:
Part 1) The speed is ![211.2\frac{ft}{sec}](https://tex.z-dn.net/?f=211.2%5Cfrac%7Bft%7D%7Bsec%7D)
Part 2) ![2,112\ ft](https://tex.z-dn.net/?f=2%2C112%5C%20ft)
Step-by-step explanation:
Part 1
<em>What is this speed on feet per second?</em>
we know that
1 hour=60 min
1 min=60 sec
so
1 hour=60*60=3.600 sec
1 mi=5,280 ft
we have
![144\frac{mi}{h}](https://tex.z-dn.net/?f=144%5Cfrac%7Bmi%7D%7Bh%7D)
Convert mi/h to ft/sec
![144\frac{mi}{h}=144\frac{(5,280)}{(3,600)}=211.2\frac{ft}{sec}](https://tex.z-dn.net/?f=144%5Cfrac%7Bmi%7D%7Bh%7D%3D144%5Cfrac%7B%285%2C280%29%7D%7B%283%2C600%29%7D%3D211.2%5Cfrac%7Bft%7D%7Bsec%7D)
Part 2
At this speed how many feet will the parachutists fall during 10 seconds on free fall?
Multiply the speed by the time to obtain the distance
so
![211.2\frac{ft}{sec}(10\ sec)=2,112\ ft](https://tex.z-dn.net/?f=211.2%5Cfrac%7Bft%7D%7Bsec%7D%2810%5C%20sec%29%3D2%2C112%5C%20ft)
Answer:
no

Triangles must add up to 180 degrees
The answer is H I think hope this helps!
Answer:
24 in
Step-by-step explanation:
Compare "like" things:
Big/small = Big/small
30/L = 10/8
Crossmultiply
240 = 10L
Divide by 10
240/10 = 10L/10
24 = L
Finding the area would be length x width, but to find the width we'd need to use Area / Length
The area = 44
The Length = 3 and 2/3
Solve
44 ÷ 2 and 2/3 = 12
12 is your answer
