2/5 is equivalent to 4/10 so at the end of February 4/10 was used up
And at the end of January, 3/10 was used
so 4/10 + 3/10 = 7/10

At the end of February, 7/10 of the wood was used

a big water tank contained 200 litres of water. during the day, 88 l 580 ml of water was used and 200 ml leaked. how much water
algol13

The quantity of water left in the tank as described in the task content is; 111 l 220ml.

<h3>What is the amount of water left in the tank?</h3>

The tank described in the task content initially contains 200 liters, in which case, 1 liter corresponds to 1000ml.

Hence, when 88l 580ml was used, the remaining quantity of water is; 200l - (88l 580ml) = 111 l 420ml.

And finally, since 200 ml leaked, the quantity of water left is; 111l 220ml.

Integrated science, kinda need help. Take your time!
poizon [28]

Answer:

Your friends data

Step-by-step explanation:

The rule of statistics is: the more exact the data, the better.

Here it seems that you got less precise data, as you can see. This also causes the possibility of mistakes.

This is because when you have data that is more exact, you get a better estimation for mean, median, etc. This can help make patterns in your data.

This means that your friend had better data than you.

Hope this helped!

Below is a piece of a local pizza place menu where Jacob works.

It is not reasonable because if someone were to add 4 toppings, the price would be $20.41. However, if a person were to add 3 toppings using that equation, the price would $19.02.

Ahoy there, matey! Our pirate ship had 5/6 of a treasure chest full of gold.
Kisachek [45]

Answer:

1 \frac{5}{24} teasure chests of gold

Step-by-step explanation:

Since this is a problem of adding or subtracting fractions, you will have to do one or the other to solve.  Since the pirates already had \frac{5}{6} of a treasure chest of gold and stole another \frac{3}{8} of a treasure chest to add to their collection, we need to add these two fractions:

\frac{5}{6}+\frac{3}{8}

In order to add or subtract fractions, you need to have a common denominator.  Choosing a common denominator means looking for the lowest common multiple of the two denominators:

6: 6, 12, 18, 24

8: 8, 16, 24

\frac{5}{6}=\frac{20}{24}and\frac{3}{8}=\frac{9}{24}

Add them together:  \frac{20}{24}+\frac{9}{24}=\frac{29}{24}=1\frac{5}{24}
