There are 850 douglas fir and ponderosa pine trees in a section of forest bought by karamazov logging co. the company paid an average of $300 for each douglas fir and $225 for each ponderosa pine. if the company paid $217,500 for the trees, how many of each kind did the company buy? 500 douglas firs and 350 ponderosa pines 350 douglas firs and 500 ponderosa pines 450 douglas firs and 400 ponderosa pines 400 douglas firs and 450 ponderosa pines

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
