Answer:
150 Wh
Step-by-step explanation:
We know the energy per bulb is 10 Wh per hour, so the total energy used by 3 bulbs in 5 hours is ...
(10 Wh/(bulb·hour))×(3 bulbs)×(5 hours) = 10·3·5 Wh = 150 Wh
The <u>whole number</u> <u>closest </u>to √22 is 5.
The square root of 22 is:
= √22
= 4.69
The whole number that it is closest to will <u>depend on the first decimal point</u>.
If it is 5 or above then it will be closest to 5.
If it is 4 and below, then it is closest to 4.
The first decimal point is 6 so √22 is closer to 5.
In conclusion, the square root of 22 is closer to 5.
