C=d x pi
d= 24
C= 24 x 3.14
C=75.36 inches
hope this helps
2/3 a mile in half an hour
3 hours=6 x 2/3
6/1 x 2/3 = 12/3
12/3 =4 miles in 3 hours
Answer:
1. <B, <A, <C
2. <E, <D, <F
Step-by-step explanation:
Recall: the longest side of a triangle would be opposite the largest angle, while the shortest side of a triangle would be opposite the smallest angle.
1. <B is opposite the shortest side, 3 (smallest angle)
<A is opposite the medium side, 4 (medium angle)
<C is opposite to the largest side, 5 (largest angle)
Therefore, the angles in ascending order would be:
<B, <A, <C
2. <E is opposite the shortest side, 5 (smallest angle)
<D is opposite the medium side, 6 (medium angle)
<F is opposite to the largest side, 7 (largest angle)
Therefore, the angles in ascending order would be:
<E, <D, <F
Assume uniformly accelerated motion
Vf = Vo - at => a= [Vo - Vf] / t
Vf = 0, t = 20 s => a = Vo / 20
x = Vot - at^2 / 2
x = Vot - (Vo / 20) * t^2 /2
x = 1775 feet * [1 mile / 5280 feet] = 0.336 mile
t = 20 s
=> 0.336 = 20Vo - Vo(20)^2 /(40) = 20Vo - 10 Vo = 10 Vo
=> Vo = 0.336 /10 = 0.0336 mile /s
Vo = 0.0336 mile/s * 3600 s/h = 120.96 mile / h
Therefore, the car was way over the speed limit.
