Answer:
9 x 24 x 1/2(basically dividing by 2) = 108
, 108 x 2(two triangles) = 216
40 x 15 = 600, 600 x 2(two slanted rectangles) = 1200
40 x 24 = 960 (area of base)
Add given areas:
216 + 1,200 + 960 = 2,376 square feet, B.
Answer:
c
Step-by-step explanation:
Answer:
(72/17) hours
Step-by-step explanation:
Time Jackie would take alone , J = 8 hrs
Time Patricia would take alone , P = 9 hrs
Let the time they will take together be T
use the formula for shared unit rate
=
+ ![\frac{1}{P}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BP%7D)
=
+ ![\frac{1}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D)
= ![\frac{17}{72}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B72%7D)
T =
hours (or 4.24 hours)
A) The speed of the parachute in feet per second is; 198 ft/s
B) At the given speed, the number of feet the parachute will fall during 15 seconds of freefall is; 2970 ft
We are given;
Speed of parachute during freefall = 60 m/s
A) We are told that 1 m = 3.3 ft
Thus, 60 m/s in ft/s = 60 × 3.3/1 = 198 ft/s
B) Speed is now 198 ft/s
Time is 15 seconds
Formula for distance is;
Distance = speed × time
Distance = 198 × 15
Distance = 2970 ft
