darren lives 7/10 from the school and belinda lives 1/3 from the school. how much farther does darren live then belinda? hurry

11/30

Step-by-step explanation:

You need to convert everything to a common denominator, so you would change everything into x/30 so 7/10 is equal to 21/30 and 1/3 is equal to 10/30 so you would just subtract 21-10 and get 11/30

step-by-step explanation:

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.
