A family uses 1,303 kWh of electric energy in a month. If the power company charges $0.08 per kilowatt hour, what is the total e

prisoha [69]

The total electric energy bill for the month is $\$104.24$

<u>Solution: </u>

Given that

Electric energy consumed by family in a month = 1303 kWh

Power Company charges $\$0.08$ per kilowatt hour

Need to calculate total electric energy bill for the month.

Price of 1 kilowatt hour = $\$0.08$

$\text { Price of } 1303 \text { kilowatt hour }=1303 \text { x Price of } 1 \text { kilowatt hour }=1303 \times 0.08=\$ 104.24$

Total electric energy bill for the month = Price of Electric energy consumed by family in a month = Price of 1303 kilowatt hour = $\$104.24$

Polynomial division (-12m^2-49mn-44n^2)/(-3m-4n)

Ket [755]

First factor -12m^n - 49mn - 44n^2 to get -(4n+3m)(11n + 4m) then the equation would be:
-(3m + 4n)(4m + 11n) / (-3m - 4n)
Then, cancel out the like terms and the final answer would be
4m + 11n

Someone please help me answer this!!

dybincka [34]

Answer:

17.9 units is the answer

Step-by-step explanation:

points are (-7,-2) and (9,6)

Pythagorean theorem can be written as,

$d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{9-(-7))^2 + (6-(-2))^2}\\\\d=\sqrt{(16)^2+(8)^2} \\\\d=\sqrt{256+64} \\\\d=\sqrt{320} \\\\d=17.88$

Rounding off,

d = 17.9 units

A parking meter charges $2 per hour. as a driver parks her car, she notices that the parking meter has 15 minutes remaining on i

Ne4ueva [31]

<span>The parking meter charges $2 per hour, means that each half hour costs $1.

Thus, 1$ pays for half an hour, so d $ pay for d half hours, that is d/2 hours, which is 0.5d hours.

15 minutes a quarter of an hour, which is 0.25 h.

Thus, the driver has a total of d/2 hours that she payed for, + 1/4 hour from the previous driver. These make a total of 3 hours, so we can set the equation:

3=0.5d+0.25

Answer: B</span>
