A forest covers 58,000 acres. A survey finds that 0.7​% of the forest is​ old-growth trees. How many acres of​ old-growth trees are​ there?

406

Step-by-step explanation:

0.7 % / 100 = 0.007

58000 * 0.007 = 406 acres

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

853.3
