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

Marina spent $13.50 at the grocery store. She bought pears, kiwis, and pineapples. Pears cost $0.50 each, pineapples cost $1.50
kiruha [24]

Answer:

Number of pineapples = 10

Number of pears = 10 + 9 = 19

Number of kiwis = 10 - 2 = 8

Step-by-step explanation:

Money = $ 13.5

Cost of a pear = $ 0.5

Cost of a pineapple = $ 1.5

Cost of a kiwi = $ 0.3

let the number of pineapple = p  

Number of pears = p + 9

Number of kiwis = p - 2

Cost is

0.5 (p + 9) + 0.15 p + 0.3 (p - 2) = 13.5

0.5 p + 4.5 + 0.15 p + 0.3 p - 0.6 = 13.5  

0.95 p = 9.6

p = 10

So, number of pineapples = 10

Number of pears = 10 + 9 = 19

Number of kiwis = 10 - 2 = 8

Ne4ueva [31]
To solve the equation:

\frac{u - 3}{4}  = 4 \\ \frac{u - 3}{4}  \times 4 = 4  \times 4\\ u - 3 = 4 \times 4 \\ u - 3 + 3 = 16 + 3 \\ u = 16 + 3 \\ u = 19

Therefore, the answer is u=19.

Hope it helps!

How much sugar does the recipe for a full batch of cookies call for
olchik [2.2K]

Answer:


Step-by-step explanation:

2/3 cup is 1/4 of recipe to total, then X would be 4/4 of the recipe.

2/3              X

------   =     --------

1/4                 1

Cross multiply and you get x/4 = 2/3, simplfy to 3x=8, divide by 3 and you get 8/3 of a cup for the whole recipe. 8/3 is the same as 2 and 2/3 cup
