A box containing oranges weighs 60kg. The empty box weighs 7.5kg. If the average weight of an orange is 75g, how many oranges are there in the box?​

700 oranges

Step-by-step explanation: mass of box is reduced first.

Mass of oranges is 60 kg -7.5 kg = 52.5 kg

Mass or oranges is divided by mass of one orange 75 g = 0.075 kg.

52.5 kg/0.075 kg= 700

answer:

your answer is: c. 196 7/8 in^3.

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.
