Brian's Bakery sells loaves of Italian bread for $3.50 and loaves of rye bread for $2.80. Brian's goal is to bring in $420 per day from sales of these two items.
Write a linear equation that describes the problem. If Brian sells 100 loaves of Italian, how many rye does he need to make his goal?

answer: howdy

step-by-step explanation:

i belive those are the ones that are under 90 degreese.

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.
