An arborist examined trees in an orchard to see if they were infected with a virus. The arborist counted 464 infected trees and 336 healthy trees. What percentage of the trees in the orchard were infected?

Correct Infected trees 58%

Step-by-step explanation:

We can set the classical proportion, but the required percentage is faster when we divide the number infected with the total number of trees and multiply by 100, which means

x% = (464/800) · 100 = 58%

God is with you!!!

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
