If the rental skis at Mt Buller were lined up end to end, they would reach from the summit of Mt Buller all the way down to the entry gate at Mirimbah. The average length of a downhill ski is 1.5 m and the distance from the Mt Buller summit to Mirimbah is 18.3km . How many rental skis are there?

There are 12,200 rental skis

Step-by-step explanation:

The distance the rental skis would reach if they were lined up end to end = From Mt Buller summit to Mirimbah

The average length of each downhill ski, l =  1.5 m/ski

The distance from Mt Buller summit to Mirimbah, D = 18.3 km = 18,300 m

The number of rental skis at Mt Buller, n = D/l

∴ n = 18,300 m/(1.5 m/ski) = 12,200 skis

The number of rental skis at Mt Buller, n = 12,200 skis

(We have that there are two skis per pair, therefore, the number of pairs of skis at Mt Buller = 12,200 ski/2 = 6,100 pairs of skis)

step-by-step explanation:

i need the pts ignore this answer

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.
