Aforest covers 66,000 acres. a survey finds that 0.8% of the forested old-growth trees. how many acres of old-growth trees are there?

528

Step-by-step explanation:

Find 0.8% of 66,000

Do this through the proportional method.

x = unknown value

0.8% / 100

=

x / 66,000

Cross multiply

66,000 x 0.8

52,800

Now, since a percent is always over a 100, divide it by 100.

52,800/100

528

im not quite sure if this is right but i got 5.6 oisutuve

step-by-step explanation:

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
