Answer:
Circle requires ≈ 20 m of edging
Step-by-step explanation:
A = πR²
R = √(A/π)
C = 2πR = 2π√(A/π)
C = 2π√(30/π) = 19.41625... ≈ 20 m
square needs ≈ 22 m of edging
equilateral triangle needs ≈ 25 m of edging
Answer:
1/90.
Step-by-step explanation:
the pattern goes up by eight.
it would continue like so:
1/2, 1/10, 1/18, 1/26, 1/34, 1/42, 1/50, 1/58, 1/66, 1/74, 1/82, 1/90.
1/90 would be the 12th number in the sequence.
Answer:
(-239.4, 657.8) km/h
Step-by-step explanation:
Measured CCW from the +x axis, the angle at which the airplane is traveling is 110°. Then the (x, y) components of the velocity vector are ...
(700 km/h)(cos(110°), sin(110°)) ≈ (-239.4, 657.8) km/h
So, let's see, Amber made 3 penalty shots off 4, now, 3 out of 4 is 75% or 3/4. So she's 75% of the time effective.
Lindsay has made 4 out of 6 penalty shots, 4/6 or 2/3, that's about 66% effectiveness.
Li has made 2 out of 3 penalty shots, that's 2/3, that's about the same 66% effectiveness.
so, which fraction is highest 3/4, or 2/3 or 2/3? neverminding the percentages, let's multiply all by the LCD, let's see from 4, and 3, and 3, the LCD is 12.
so, let's multiply all of them by 12, to get rid of the denominator, to see which is highest.

notice, Amber has the higher effectiveness rate, to make it through in the penalty kick.
