An arborist examined trees in an orchard to see if they were infected with a virus. The arborist counted 48 infected trees and 32 healthy trees. What percentage of the trees in the
orchard were infected?

PLEASE HELP THIS IS MY LAST MISSING ASSIGNMENT

60%

Step-by-step explanation:

48 + 32 = 80

(48/80) * (100/100) = 60%

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
