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

Answer:

5040 watts i think

Step-by-step explanation:

1440 X 3  = 4320        24 / 12 = 2

1440 /  2 = 720

4320 + 720 = 5040

Answer:

The answer is -33.

Step-by-step explanation:

To solve the given equation we will follow the PEDMAS rule.

PEDMAS stands for :

  • \purple\star P = Parentheses
  • \purple\star E = Exponents
  • \purple\star M = Multiplication
  • \purple\star D = Division
  • \purple\star A = Addition
  • \purple\star S = Subtraction

Solving the question by PEDMAS rule :

\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 - \Big( - 27 - 31\Big) + 40\bigg\}}}}\end{gathered}

\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36 - \Big( - 58\Big) + 40\bigg\}}}}\end{gathered}

\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36  + 58 + 40\bigg\}}}}\end{gathered}

\begin{gathered}{\implies{\sf{29 - \bigg\{ - 36  + 98\bigg\}}}}\end{gathered}

\begin{gathered}{\implies{\sf{29 - \Big\{  \: 62 \: \Big\}}}}\end{gathered}

\begin{gathered}{\implies{\sf{29 -  62}}}\end{gathered}

\begin{gathered}{\implies{\sf{ - 33}}}\end{gathered}

\begin{gathered}  \star{\underline{\boxed{\sf{\red{ - 33}}}}}\end{gathered}

Hence, the answer is -33.

The Greatest Common Factor of the given expression should be that expression that can divide both. First, factor both expression,
           x^4 = (x³)(x)      and x³ = (x³)(1)
Therefore, both can be factored by x³. The answer is the third choice.

What is the missing constant term in the perfect square that starts with x2 – 16x?
andre [41]

Answer:

64

Step-by-step explanation:

the expression is

x² - 16x + _

the constant term is the square of the number residing with x divided by 2

the number number x = 16

therefore the constant term is (16/ 2)²

= 8²

= 64

the formula being used here is

(x + a)² = x² + 2ax + a²
