43,000 in scientific notation is 4.3 x 10^4
P = 2(L + W)
P = 200
L = W + 80
200 = 2(W + 80 + W)
200 = 2(2W + 80)
200 = 4W + 160
200 - 160 = 4W
40 = 4W
40/4 = W
10 = W.........the width is 10 yds
Answer:
4π in ≈ 12.57 in
Step-by-step explanation:
One full revolution (2π radians) is made in 60 minutes. In 40 minutes, the hand moves through an angle θ of (40/60)(2π) = 4π/3 radians. The length of the arc is ...
s = rθ = (3 in)(4π/3) = 4π in ≈ 12.57 in
Answer:
24/60 = 2/5
Step-by-step explanation: dont have one
Answer:
1)
A. <em>x</em> = 85/7
I used the formula length = area divided by width to get a.
2)
B. <em>w </em>= 85.6/12
I used the formula width = area divided by length to get b.
