To find out the box number the boxes, extract the same number of balls as the number of the box, calculate the total weight.
<h3>What are the steps to find the box with the 29 kg balls?</h3>
Considering you can only weigh the balls extracted once and you need to find the box with balls that are 1-kilo lighter; here are the steps you can follow:
- Number the boxes from 1 to 19.
- Extract the same number of balls as the number given to the box. For example, from box 9 extract 9 balls.
- Weight all the balls together.
- Find out the box with the 29 kg balls. Here is an example:
The total weight using this method would be 6,300 kg which is the result of adding 30 kg (first box) + 60 kg (second box)... However, since there is a box with lighter balls the total weight will be less.
Let's imagine the weight is 6,290, this means there are 10 fewer kilos and therefore the box with the lighter balls is box 10 since this is the box number from which 10 balls were extracted.

gives an average cost per unit, if we want to produce x of them.
So for example, we want to produce 500 toy cars for our store, and we need a price per unit (per 1 toy car). What we do is we calculate C(500).
So to calculate the cost of one unit when producing 1250, we calculate C(1250)
$ is the cost of 1 toy car.
Answer
Answer:
Round 33 percent to 30 percent and 87 to 90. Think of 30 percent as 10 percent + 10 percent + 10 percent. Find 10 percent of 90 as 9. So, 30 percent of 90 is 9 + 9 + 9, which is 27.

For the first table, the y-values are not equally spaced and the ratios of y are not the same, but by plotting them and observing the graph that results, it looks like the points lie on an exponential curve. The second table is linear because when x changes by 1, y changes by 4. The third table is a quadratic model because even if the first differences of y are not the same, the second differences of y have the same value of 8. The fourth table is exponential because the ratio of y-values is 2, which is the same between each set of numbers.
Answer:
<em>-0.375 or -3/8</em>
<em>(depending on if it asks for a fraction or a decimal)</em>
Step-by-step explanation:
-15/8 = -1.875
-1.875 + 1.5 = -0.375
-0.375 = -3/8
