Id take a guess and say line 1 because the rest looks correct
<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.
If u mean 62 times 45 on its own, then the answer is 2790. hope that helped!!
Answer:
(-2, -3)
Step-by-step explanation:
90° clockwise rotation:
(x, y) -----> (y, -x)
Let's apply this to our coordinates:
(x, y) -----> (y, -x)
(3, -2) -----> (-2, -3)
Simply make the old y-coordinate the new x-coordinate, and make the old x-coordinate negative and make the new y-coordinate.
Therefore, the coordinate of the new point is (-2, -3).
