The richter scale measures the magnitude r of an
earthquake. it is defined by the formula
r = 0.67 log(0.37e) + 1.46
where e is the energy, in kilowatt-hours, released
by the quaker the 1933 quake in japan measured
8.9 on the scale. in scientific notation with
3 significant digits, how much energy was
released?

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

step-by-step explanation:

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
