Answer:
7 m
Step-by-step explanation:
63/9=7 and 7*9=63
<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.
