4) 10% or 1/10
5) 24% or 6/25
6) 34% or 17/50
8) 8% of 2/25
Answer:
If they are travelling in opposite directions, their total distance is the 135. So add their distances together to get 135
x=Quinn's speed
x+5 = James' speed
they each travel for 5 hours
speed x time = distance
x(5) + (x+5)(5) = 135
Quinn's distance + James' distance = total distance
5x+5x+25=135
10x = 110
x = 11
Quinn travels at 11 mph and James travels at 16 mph
Quinn travels 55 miles (5x11)
and James travels 80 miles (16 x 5)
80 + 55=135
Answer:
∠ L ≈ 21.6°
Step-by-step explanation:
Using the Sine rule in the triangle
= 
, that is
= 
( cross- multiply )
42 × sinL = 34 × sin27° ( divide both sides by 42 )
sinL = 
, then
∠ L = 
( ) ≈ 21.6° ( to the nearest tenth )
