Answer:
Peter gets £13.158 for each kWh of electricity he produces.
Step-by-step explanation:
Peter buys a small wind turbine
Total electricity produced by wind turbine in first year = 13,000 kWh
Total electricity used by Peter = 7570 kWh
Electricity sold to energy suppliers = ?
Total amount of money he gets after selling x electricity to energy suppliers = £412.68
We can se that:
Total electricity produced = Electricity used by Peter + Electricity sold by Peter
Electricity sold by Peter = Total Electricity produced - Electricity used by Peter
Electricity sold by Peter = 13,000 kWh - 7570 kWh = 5430 kWh
Total amount earned = £412.68
So
Price per kWh = Electricity sold by Peter/Total Amount earned
Price per kWh = 5430/412.68
Price per kWh = £13.158
Answer:
The ratios are not equivalent
Step-by-step explanation:
First, in order to find the ratios, we have to change the month to the amount of days.
There are 30 days in April, so we will use this for the ratio.
The ratio for the 3 day weekend is 5:3
The ratio for the month of April is 60:30, which can be simplified to 2:1
So, the ratios are not equivalent, because 5:3 is not equal to 2:1

Answer: -1</h3>
Explanation:
The given equation is the same as y = -1x^4+4x^2
The leading term is the term with the largest exponent, so it's -1x^4
The leading coefficient is the coefficient of the leading term.
In short, we circle the first coefficient we see. This is assuming that the polynomial is in standard form where the exponents decrease when going from left to right.
Let c and n represent the numbers of pencil and pen boxes, respectively
.. 3c +2n = 6.00
.. 2c +4n = 8.00
You can halve the second equation and subtract it from the first to get
.. (3c +2n) -(c +2n) = 6.00 -4.00
.. 2c = 2.00
.. c = 1.00
Then
.. 1.00 +2n = 4.00 . . . . . half the original second equation with c filled n
.. 2n = 3.00
.. n = 1.50
A box of pencils costs $1.00; a box of pens costs $1.50.
