Answer:

Each side is 35.78 mm

Step-by-step explanation:

Jan's house has four leaking taps. An average of 34 cL of water leaks from each tap every day. How many litres of water is lost
pshichka [43]

Answer: 42.16l

Step-by-step explanation:

First, we should note that August has 31 days. Since Jan's house has four leaking taps and an average of 34 cL of water leaks from each tap every day. The four taps will leak (34 × 4) = 136 cL everyday.

The amount of litres of water that is lost from these four taps in August would be:

= 136cL × 31

= 4216 cL

= 42.16L

We should note that 100cL = 1L

HELP IM USING ALL MY POINTS
Romashka-Z-Leto [24]

Answer:

5 days

Step-by-step explanation:

If you write it out it will look like this 8 1/2÷1 7/10

since you can't divide mixed fractions very easily, you make them improper fractions. 8 1/2 -> 17/2    1 7/10 -> 17/10

So it looks like 17/2÷17/10
