Answer: it consumes 5040 watt hour in 3 days and 12 hours

Step-by-step explanation:

light bulb consumes 1440 watt hours per day. The number of hours in a day is 24. This means that the consumption of the light bulb per hour would be

1440/24 = 60 watt hour.

The consumption for 12 hours would be

60 × 12 = 720 watt hour.

The consumption for 3 days would be

3 × 1440 = 4320 watt hour

The total consumption in 3 days and 12 hours would be

4320 + 720 = 5040 watt hour

5040 watts i think

1440 X 3 = 4320 24 / 12 = 2

1440 / 2 = 720

Kyra has a rock collection. When she puts her rocks into 2 equal plies, there are no rocks left over. When she puts her rocks in

Nat2105 [25]

Step-by-step explanation:

According to this description we need a number that can be divided by 2,3 and 4 since the amount of rocks can be described by a natural number. However if a number is divided by 4 it is divided by 2 as well since 2*2=4.

$\frac{x}{4} = \alpha \\ \frac{x}{2} = 2 \alpha$

If α is a natural number then 2*α is a natural number as well as the product of two natural numbers.

Which means that we need a number devided by 3 and 4.

The smallest number that fulfills this demand is 3*4=12.

Also any product of 12 with any natural number can be devided by 3, 4 and 2.

If the exercise asks for the numbers that are divided only by 2,3 and 4 these are:

${3}^{ \alpha } \times 12 \: and \: {4}^{ \alpha } \times 12 \: \\ where \: \alpha \: belongs \: to \: the \: set \: of \: all \: \\ natural \: numbers$
