Answer:

$\large\boxed{a=4\sqrt3}$

Step-by-step explanation:

We have the triangle 30° - 60° - 90°. In that triangle sides are in proportion

1 : √3 : 2 (look at the picture).

We have

$a\sqrt3=12$ multiply both sides by √3 (use √a · √a = a)

$3a=12\sqrt3$ divide both sides by 3

$a=4\sqrt3$

$b=2a\to b=2(4\sqrt3)=8\sqrt3$

The double number line shows the amount of time a hen needs to lay 1 egg.

Scorpion4ik [409]

I realize the double number line in this exercise can be as shown in the attached image, in that case, the table, correctly completed is:

Eggs Time (hours)

3 75

4 100

12 300

Method to complete the table.

First, you must see the double number line (attached image), in this we identify a hen needs 25 hours to lay 1 egg, by this reason, to identify the time required for a certain number of eggs, just multiply the number of eggs by 25 (the number of hours shown on the double number line), then:

3 * 25 = 75
12 * 25 = 300

To calculate the number of eggs taking into account the time, you must divide the hours by 25:

100 / 25 = 4

In this way, you can check that the answers are 75, 4, and 300 respectively, to complete the table in the correct form.
