Answer:

The amount of water must be added to this task = 60 cm^{3}

Step-by-step explanation:

Let amount of water added = x cm^{3}

Then from the given conditions

A chemist would like to dilute a 90-cc solution that is 5% acid to one that is 3% acid. So

90 (0.05) = 0.03 ( 90 + x )

4.5 = 2.7 + 0.03 x

0.03 x = 1.8

x = 60 cm^{3}

Therefore the amount of water must be added to this task = 60 cm^{3}

SVETLANKA909090 [29]

Answer:

35w^3 + 44w

<em><u>Combine Like Terms:</u></em>

= 35w + 9w + 35w^3 + 25w^3 - 25w^3

= (35w^3 + 25w^3 - 25w^3) +(35w + 9w)

= 35w^3 + 44w

Hope this is right ♡

o-na [289]
To solve this problem you must apply the proccedure shown below:

 1. You have the following logarithm:

 <span>log(2)n=4

 2. Therefore, you con rewrite it as below:

 loga(b)=logb/loa
</span>
 3. Therefore, you have:

 log(2)n=4⇒log(n)/log(2)=4
 
 4. Then, you obtain:

 log(n)=4log(2)

 5. Therefore, as you can see, the answer for the exercise shown above is the last option, which is:

 log(n)=4log(2)
