Amixture contains five quarts of acid and water and is forty percent acid. if the mixture is to be weakened to thirty percent acid, how much water must be added? 2/3 quarts 1/2/3 quarts 2/2/3 quarts

Second option is correct.

Step-by-step explanation:

Since we have given that

Amount of quarts of acid and water = 5

Percentage of acid = 40%

So, Amount of acid is given by

Amount of water is given by

So, we need to find the amount of water must be added to the mixture to get weakened to 30% acid.

Let x amount of water is added to mixture, so that water gets 70% of mixture and acid becomes 30% of mixture.

According to question,

Hence, Second option is correct.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
