<span>7<span>12</span></span> hours

Explanation:

Vacuum cleaner uses <span><span>58</span>=<span>1016</span></span> kilowatt per hour

Clothes dryer uses <span>4<span>1116</span>=<span>7516</span></span> kilowatt per hour

To see how many hours we can run the vacuum cleaner for using the same amount of energy as the dryer does for one hour, we can divide the vacuum cleaner energy into the dryer energy:

<span><span><span>7516</span><span>1016</span></span>=<span>7516</span>×<span>1610</span>=<span>7510</span>=7.5</span>

Jonas can run his vacuum for <span>7<span>12</span></span> hours using the same amount of energy that the dryer does in one hour.

Elvira is 5 years older than Morton. Morton is twice as old as Michelle. The combined total of their ages is 85. How old is Mort
LiRa [457]

Elvira (e) is 5 years older than Morton (m)

e = m + 5

Morton (m) is twice as old as Michelle (c)

m = 2c

The combined total of their ages is 85

e + m + c = 85

We want m at the end so let's write everything in terms of m.

e = m + 5

c = m/2

85 = e + m + c = m+5 + m + m/2 = 5 + (5/2) m

m = (2/5) (85 - 5) = 32

Answer: 32 years old

Check:

That makes Elvira 37 and Michele 16, total 32+37+16=85, good

What percent of 72 is 9? <br><br> 18% <br><br> 1 1/4% <br><br> 12 1/2% <br><br> 125%
Semmy [17]
The only reasonable answer would be 12 1/2 because 10 percent of 72 is 7.2 and there's no other closer one.
