Answer:
11-60-61
Step-by-step explanation:
For right triangle, leg^2+Another leg^2=hypotenuse^2
11^2+60^2=61^2
Answer: 151.25 cm^2
explanation: separate into rectangle and semi circle. you can find out the diameter and radius of the semi circle by subtracting the 6 from the top from the 16 of the bottom because the diameter of the circle plus the 6 take up the same length.
16 - 6 = 10
for radius divide by 2
10 / 2 = 5
area of rectangle: l x w
16 x 7 = 112
area of semi circle: 1/2(pi)r^2
1/2(3.14)5^25 = 39.25
add up the two areas to find the area of the entire figure
112 + 39.25 = 151.25
Answer: 7.0s
10=20t-1/2(9.8)t^2 multiply every term by 2 and move all terms to one side
t^2-40t+20=0 solve for t using quadratic formula and double answer for total flight time.
t=3.498*2=7.0s
66 x 3 = 198
198 + 2 = 200
200 / 3
As an improper fraction, anyway. 66 2/3 is already *technically* a fraction.
4.225% maybe
