There are 20 children at a library. Six of the children have an average age of 5 years. The remaining children have an average a

Allushta [10]

Answer: The average age is 7.1 years.

This problem is an example of when we need to take a weighted average. We simply can't just find the average of 5 and 8, because there are different children of each each.

To start, lets multiply the total number of children by their individual ages.

6 x 5 = 30 years
14 x 8 = 112 years

There are 142 years among the 20 years, so divide 142 by 20. This gives us an average age of 7.1 years.

Please help: If the area of a rectangular picture of a stamp is 81 times greater than the actual stamp's area, and the stamp has

ololo11 [35]

Answer:

12 inches.

Step-by-step explanation:

We know that the length of the stamp is 4/3 inches.

Let the width be x inches.

Then the area of the actual stamp is:

$\frac{4}{3}x\text{ inches}^2$

We know that the rectangular picture of the stamp is 81 times greater than the actual stamp’s area. Therefore, the area of the picture is 81 times the above. So:

$81(\frac{4}{3}x)\text{ inches}^2$

So, the area of the rectangular picture is the area of the actual stamp multiplied by a scale factor k.

When we use the scale factor to scale area, we need to square it. Hence, the area of the actual stamp times the scale factor squared is equal to the area of the rectangular picture. Therefore:

$\frac{4}{3}x(k^2)=81(\frac{4}{3}x)$
