The common multiple for 1/2 1/4 1/6 1/3 and 1/5 would be 60:
2 x 30 = 60
3 x 20 = 60
4 x 15 = 60
5 x 12 = 60
6 x 10 = 60
Decrease = (original number - new number) / original number .....x 100
decrease = (49 - 22) / 49.....* 100 =
(27 / 49) * 100 =
2700 / 49 = 55% decrease
Either 75 or 105 would be my answer
Answer:
x ≈ 9.5 , y ≈ 15.3
Step-by-step explanation:
sin32° =
=
( multiply both sides by 18 )
18 × sin32° = x , then
x ≈ 9.5 ( to the nearest tenth )
cos32° =
=
( multiply both sides by 18 )
18 × cos32° = y , then
y ≈ 15.3 ( to the nearest tenth )
