1. A set of steps leads down into a swimming pool. Some of the steps are above the water level and some of the steps are below the water level. The top of one of the steps is even with the water level of the pool. Each step is 8 inches tall. Positions below the water level are represented as negative values and positions above the water level are represented as positive values. Madison's feet are on the step that is even with the water level of the pool. Madison steps 1 step down. (a) What numeric value represents the position of Madison's feet now? (b) What is the additive inverse of "Madison steps 1 step down?" Describe the additive inverse in terms of the situation. Explain how you know this is the additive inverse.

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

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.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
