kow [346]

Answer:

56 quizzes

Step-by-step explanation:

40 quizzes = 5 weeks

To find the unit rate of quizzes / week, we can divide both sides by 5

40/5 quizzes = 5/5 weeks

8 quizzes = 1 week

Multiply both sides by 7 to find the amount of quizzes in 7 weeks

8 * 7 quizzes = 1 * 7 weeks

56 quizzes = 7 weeks

6 workers can build a wall in 30 days. If after 6 days 3 more workers join, find the number of days to build the same wall?
viktelen [127]

The wall can be built in 22 days by 6 workers in first 6 days and 9 workers in the rest of time.

<h3>How to use inverse proportionality to determine building time of a wall</h3>

In this question we must use the definition of <em>inverse</em> proportionality, in which the number of workers (n), no unit, is inversely proportional to the <em>building</em> time (t), in days.

According to the statement, 6 workers spent 6 days building a wall and there are 24 days left for completion, but 3 more workers entered to reduce building time, which can be represented by the following expression:

x = 24\,days \times  \frac{6}{9}

x = 16\,days

In this scenario, the wall can be built in 22 days. \blacksquare
