A blue spruce grows an average of 6 inches per year and a hemlock grows an average of 4 inches per year. If a blue spruce is currently 4 feet tall and a hemlock is 6 feet tall , when would you expect the trees to be the same height.

It will take 12 years for the trees to be at the same height.

Step-by-step explanation:

12 years

Step-by-step explanation:

blue spruce = 0.5 ft/yr & 4 ft tall

Hemlock = 0.33 ft/yr & 6 ft tall

x = number of years

spruce       hemlock

(4+0.5x)   =   (6+0.33x)

0.17x = 2

12 years

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.
