Mac used a 7 metre long metal rod to make flag poles. He used 36cm to make each longer pole and 12cm to make each shorter pole. He made an equal number of longer and shorter
poles. At the end of the day, he had 28cm of metal rod remaining. How many poles did he
make?

​

555.99.

step-by-step explanation:

hope this

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.

mean, 40.6
