It will take 30 minutes more for remaining grass.
As he mowed 40% in 20 minutes, it shows that he mows twice percentage of grass in the time calculated in minutes.
So it will take 30 minutes for remaining 60% grass.
Answer:
10 kg
Step-by-step explanation:
In 3% concentration of 20 kg of seawater, there will be 
kg of salt.
So, if it is a 2% solution of seawater,
Then 2 kg salt will be there in 100 kg solution.
So, 0.6 kg salt will be there in 
kg of solution.
So, to make a solution from 3% to 2% we have to add (30 - 20) = 10 kg of water with a 20 kg solution. (Answer)

1% of the original value ×20 is £92.64. Add that to the original value (£463.20)
Answer:
100 Cos 40° + 100 Sin 40° ≈ 141 yards
Step-by-step explanation:
From the diagram, side x is adjacent to the angle 40° while side y is the opposite to that same angle
This means that;
Cos 40° = x/100
x = 100 Cos 40°
Sin 40° = y/100
y = 100 Sin 40°
Therefore, total distance walked = x + y
" = 100 Cos 40° + 100 Sin 40° ≈ 141 yards
