Eric is finding money in his coin jar to go to the carnival. He does not want to spend more than $30 there. Which inequality represents this statement? A s < 30
B s > 30
C s ≤ 30
D s ≥ 30

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

it could be 1,3 and more others to create a cylinder.

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.
