Answer:

x = 8 and y = 18, and the scale factor is 3/2

Step-by-step explanation:

Because we have two complete pairs in the similar trapezoids, we can find the scale factor as 3/2, or 36/24 or 24/16.

To find the missing values of x and y, we just make the equations to get 3x/2 = 12 and 12 * 3/2 = y. This means x = 8 and y = 18.

I may be wrong but my answer is

The slave population is high because of all of the growing crops and they need labor to grow more crops and harvest them. so of course there would be more slaves in those areas, with the most crops. So you can say the slave population in the colonies is high

Stiind ca triunghiurile sunt asemenea si c= 5 calculati lungimea laturilor indicate

slava [35]

Answer:

$a=8\\b=10\\c=5$

Step-by-step explanation:

In the given image, you can observe we have two right triangles.

Also, we know by given that those triangles are similar, which means their sides are proportional and their angles are congruent.

If the triangles are similar, we can define the following proportion between sides.

$\frac{4}{a} =\frac{3}{6}\\ 24=3a\\a=\frac{24}{3}\\ a=8$

Now we use the Pythagorean's Theorem to find each hypothenuse.

$c^{2} =4^{2} +3^{2}\\ c=\sqrt{16+9}=\sqrt{25} \\ c=5$

$b^{2} =8^{2} +6^{2}\\ b=\sqrt{64+36}=\sqrt{100}\\ b=10$

Therefore, the missing sides are

$a=8\\b=10\\c=5$

Is my answer correct

kondor19780726 [428]

Answer:

Yes, you are correct.

Step-by-step explanation:

$\text{Let the number of puzzle solved by Child B is} x\text{.}$

$\text{Then the average number of puzzle solved is}$

$\frac{5x+x+(x+4)}{3}=13$

$\frac{7x+4}{3}=13$

$7x+4=39$

$7x=35$

$x=5$

$\text{Therefore, the number of puzzles solved by child A is }5x=5\cdot5=25$

$\color{blue}\text{A little tips here: You can check it by substituting your answer to the original equation.}$
