280 students have a total of 560 points
There 60 more boys(x+60) complete than girls(x)
2*(x+60)+2*x= 560
number of girl =x =110
girl point =110*2= 220
Answer:
the answer is number 4......
Answer: 60
Step-by-step explanation:
Just got the wrong answer to see what it was
Step-by-step explanation:
Use arc length:
s = rθ
where r is the radius and θ is the angle in radians.
a) First, convert the angle to radians (1 degree = 60 minutes).
77 ⁵⁰/₆₀° × (π radian / 180°) = 1.358 radians
s = rθ
s = (9.67 in) (1.358 rad)
s = 13.1 in
b) s = rθ
4 in = (9.67 in) θ
θ = 0.414 radians
θ = 23.7°
θ = 23° 42'
A 7 units. -3 is the same in each, so you just find the difference between 9 and 2
