Answer:
Let length of the pool be L.
Deep
A —————————————><———————————----———————————— H
.................(18.5m)
H ——————————————————————————-———><————————- A
..............................................................................................................(10.5)
In same time, Andy covers 18.5 and Hardy covers L - 18.5.
In same time, Andy covers L - 18.5 + 10.5 while Hardy covers 18.5 + L - 10.5
The ratio of these distances covered would be the same since the speeds of both people are constant.
18.5/(L - 18.5) = (L - 8)/(L + 8)
Plug in the options to find that L = 45 works.
Work out 8% of 30000
10% of 30000 is 3000
1% of 30000 is 300
2% of 30000 is 300x2=600
Therefore 10%-2%= 3000-600=2400
It therefore follows that Mayra earned 4540 + 2400 = 6940 for January
Answer:
Oil: 10.5 oz Vinegar: 3.5 oz
Step-by-step explanation:
If the amount of vinegar is the variable x than the amount of oil is 3x. this means that x+3x=14 or 4x=14. Which means x=3.5 so vinegar is 3.5 while oil is three times that or 10.5.
2=6-3 is the direct variation
