2 hours because 6 times 2 = 12 and 4 times 2 = 8 and 8 + 12 =20
Step-by-step explanation:
3q - 1 = 3(1) - 1 = 2
3q -1 = 3(2)- 1= 5
10/p = 2 10/p = 5
p= 5 p= 2 (5-2=3, so 10/p is correct)
q=5, 3(5) -1 = 14
10/p = 14
p = 0.71??
Use the formula for the length of an arc:-
L = r C where r = radius and C = angle subtended in radians So here we have:_
18 = r * 130 * pi / 180
18 = 2.269 r
r = 7.93 cm to neraest hundredth
