Answer:
4 litres
Step-by-step explanation:
First, find the volume of the entire tank using the given measurements:
To find the amount of water in cubic centimetres, simply multiply 
with 6000:
Now, we need to convert to litres. You can easily see just by looking at the numbers that the volume is 4 litres, however we will do the full conversion just to show you how it's done:
Now, the cubic centimetres cancel out as there is one on the bottom of the first fraction and one on the top of the second fraction. Anything divided by itself is one, including units, so the 1000 cubic centimetres from the first fraction and the 4000 cubic centimetres from the second fraction are multiplied by one. They therefore remain the same but without the unit of centimetres cubed:
The answer should be 1.425.
Once you subtract 0.3 from 6 it leaves you with 5.7
then do 5.7 divided by 4 and you would get 1.425
D=vt, distance is equal to velocity times time.
4v+3(v+3)=149 perform indicated multiplication
4v+3v+9=149 combine like terms on left side
7v+9=149 subtract 9 from both sides
7v=140 divide both sides by 7
v=20
So the ship traveled at a speed of 20 mph when heading east.
Answer: #444
Step-by-step explanation:
First find the original selling price of the article.
When sold for #372 the profit was 24%. Assume the original price is x.
372 = x + 24% * x
372 = 1.24x
x = 372 / 1.24
= #300
If he wanted to make a profit of 48% he should have sold for:
= Original price + (original price * 48%)
= 300 + (300 * 48%)
= #444
