Answer 1

Answer:

$276$ acres of old-growth trees are there.

Step-by-step explanation:

Given: A forest covers $69,000$ acres. A survey finds that $0.4\%$ of the forest is​ old-growth trees.

To find: How many acres of​ old-growth trees are​ there?

Solution:

We have,

A forest covers $69,000$ acres.

Now, $0.4\%$ of the forest covers old-growth trees.

So, old-growth trees covers $=0.4\%$ of $69,000$.

$=\frac{0.4}{100} \times69,000$

$=\frac{4}{1000} \times 69,000$

$=276$

Hence, $276$ acres of old-growth trees are there.

Answer 2

Answer:

276 acres in the forest.

Step-by-step explanation:

Total area of the forest = 69000 acres

Old — grown trees = 0.4%

0.4% of 69000 = 69000× 0.4/100

= 69000×0.004= 276

Old grown trees are covered 276 acres in the forest.
