Answer:

$x=\sqrt6\\y=\sqrt{12}$

Step-by-step explanation:

We know that since angles in a triangle add up to 180º, the remaining angle must be 45º.

So the side with length $x$ must be equal to the side with length $\sqrt6$ . That is:

$x=\sqrt6$

Now, by Pythagoras:

$y=\sqrt{(\sqrt6)^2+(\sqrt6)^2}\\=\sqrt{6+6}\\=\sqrt{12}$

A forest covers 37 comma 000 acres. A survey finds that 0.2% of the forest is old-growth trees. How many acres of old-growth

miss Akunina [59]

74 acres of old-growth are there in the forest

Step-by-step explanation:

To answer the question, we need to calculate the 0.2% of 37,000.We can calculate this stating that exists a linear relationship between the percentage and the number of acres. We also need to state that 37,000 acres are the 100% of the acres.

$=\frac{0.2}{100} \times 37000\\ =0.002 \times 37000\\=74$

We find that if 37,000 acres are the 100% of the acres ⇒ The 0.2% of the acres are 74 acres (in which there are old-growth trees).
