Answer : 4.5 × 10⁴ square inches can be washed per hour.
Step-by-step explanation :
As we are given that an area can be washed at a rate of 4,900 cm²/min. Now we have to determine the square inches can be washed per hour.
Given conversions are:
1 cm = 0.39 in and 1 hr = 60 min
As, 1 cm² = (0.39)² in² and 1 min = 1/60 hr
So,
Now we have to determine the square inches can be washed per hour.
As,
So,
Therefore, 4.5 × 10⁴ square inches can be washed per hour.

Answer: 5/8
hello :)
so let me just give you the answer first:
2/3 * d = 32 2/3
here is why
so since the sentence said 2/3 PER day, then d (the number of days) multiplied by the time spent each day playing piano should give you how much time was spent in total over the certian number of days.
the 32 2/3 is just the amount of time ellie spent (as you have said)
so, this equation would be the correct one.
i hope this helped you out! please vote me for brainliest and have splendid day!
