Mr. Hasson grew at a rate of 1/6 feet per year in high school. How long will it take him to grow from a height of 5 1/2 feet to a height of 6 1/4 feet?

5 years.

Step-by-step explanation:

Hope it helps!

4.5 years

Step-by-step explanation:

Mr. Hasson grew at a rate of 1/6 feet per year in high school

let ‘x’ be each year Mr.Hasson grows

therefore, 1/6x

5 1/2+1/6x=6 1/4

subtract 5 1/2 from both sides

1/6x=3/4

divide both sides by 1/6 to isolate the variable

x=4.5

it took Mr. Hasson 4.5 years to grow from a height of 5 1/2 feet to a height of 6 1/4 feet

i would need to see the dot plot : )

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.
