A) Isaac is purchasing two pairs of shoes-one pair for $37.00 and the second
pair for $42.00. The state sales tax applied to Isaac's bill is 7%. How much is Isaac's
total bill? Show your work. (2 points)
The answer is 84.53

Add both pair of shoes together. Then take that total and multiply by7% or.07

c. 4 and 1/2 pounds is the 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.
