How many quarters have the same value as 85 dimes? use the equality 4 quarters = 10 dimes.?

34 quaters have the same value as 85 dimes.

Explanation:

We are given a conversion factor:

10 dimes = 4 quaters

We need to find out the value of 85 dimes. For that we use unitary method.

If 10 dimes have the same value as 4 quaters.

So, 85 dimes will have the same value as quaters.

Hence, 34 quaters have the same value as 85 dimes.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
