A light bulb consumers 1800 watt-hours per day. How long does it take to consume 9450 watt-hours?

9900 watts-hours is how much it consumes in a period of 5 days and 12 hours.............

to check this: multiply 1800 by 5 and it equals 9000 then you divide 1800 by 2 because 12hours is a half day and it is 900 after all that you add 9000+900 and it equals 9900.

Use completing the square to solve for x in the equation (x-12)(x+4)= 9. X = -1 or 15

X = 1 or 7

X=41 141

x = 4 + 173

Answer:

x = 4 + sqrt(73) or x = 4 - sqrt(73)

Step-by-step explanation by completing the square:

Solve for x:

(x - 12) (x + 4) = 9

Expand out terms of the left hand side:

x^2 - 8 x - 48 = 9

Add 48 to both sides:

x^2 - 8 x = 57

Add 16 to both sides:

x^2 - 8 x + 16 = 73

Write the left hand side as a square:

(x - 4)^2 = 73

Take the square root of both sides:

x - 4 = sqrt(73) or x - 4 = -sqrt(73)

Add 4 to both sides:

x = 4 + sqrt(73) or x - 4 = -sqrt(73)

Add 4 to both sides:

Answer: x = 4 + sqrt(73) or x = 4 - sqrt(73)

How many days are in 3 2/7 weeks

Well, there are 7 days in a week, so we'll have to multiply that by 3, which would be 21, plus the other 2 days stated in da problem, so that would be a total of 23 days!

I hope I helped, and PLEASE choose my answer as the Brainliest!

Thank you! =D

I hope I helped, and PLEASE choose my answer as the Brainliest!

Thank you! =D

7 × 3 = 21

21 + 2 = 23

So therefore, 23 days.

21 + 2 = 23

So therefore, 23 days.

Round 483.1489 to the nearest thousandth

483.149

greater than 5, go up

lower than 5, stay the same

greater than 5, go up

lower than 5, stay the same

The 1 is the tenth, the 4 is the hundreth and the 8 is the thousandth. In this case, the nearest thousand would be:

483, 149

How do you write 12 ten thousand, 8 thousand,14 hundreds, 7 ones in standard form?

Answer:

129407

Step-by-step explanation:

We are given that 12 ten thousand, 8 thousand,14 hundreds, 7 ones

We have to write given number in standard form

12 ten thousand=120000

8 thousand=8000

14 hundreds=1400

7 ones=7

Hence, the standard form of given number is 129407.

128,147 is your answer.
