In one day, The Tool Shed rented out 25 self-propelled and riding mowers for a total fee of $900. The dally rental cost was $20 for each self-propelled mower and $40 for each riding mower. Find the number of self-propelled mowers (x)' and the number of riding mowers (y) rented for that day.

the answer is here: : )

it is c, trust i got your back lol

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.

answer: 0.64
