find the cost of operation of a central air conditioner that uses 3.5 kilowatts and runs for 12 hours a day for one week at a cost of 9.53¢ per kilowatt-hour.
Answer:2.561,664¢ or roughly 25.61$.
Step-by-step explanation:
So, the air conditioner will cost 3.5 * 9.53 ¢ = 30.496 ¢ per hour running.
That means 30.496¢ * 12 = 365.952¢ or ≈3.65$ for a day.
Or 365.95¢ * 7 = 2.561,664¢ or ≈25.61$ for a week.

A farmer sells 7.2 kilograms of pears and apples at the farmer's market.
3 4 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?
Answer:
3.8 kg of apples were sold by the farmer.
Step-by-step explanation:
Given-
Kilograms of pears: 3.4 kgs
Kilograms of apples: ?
Total: 7.2 kgs
Therefore:-
Kgs of apples + Kgs of pears = Total Kgs of fruits sold. (Given)
Kgs of apples + 3.4 kgs = 7.2 kgs (Substituting given values)
Kgs of apples = 7.2 kgs - 3.4 kgs (Taking known values to one side)
Kgs of apples= 3.8 kgs.

Use algebraic notation to describe how to transform the blue function into the red function. F\left(x\right)-1f(x)−1 f\left(x-1\right)f(x−1) f\left(x+1\right)f(x+1) f\left(x\right)+1f(x)+1
In geometry, transformations are used to move a point or points from one position to another. The notation that describes how the blue function is transformed into the red function is -f(x)
I have attached the graph of both functions.
From the attached graph, we can see that the blue function is reflected over the x-axis to produce the red function.
Let:
[tex]f(x) \to[/tex] Blue
[tex]g(x) \to[/tex] Red
The transformation of reflection across the x-axis is:
[tex]g(x) = -f(x)[/tex]
Hence, the notation that describes how the blue function is transformed into the red function is -f(x)

Given f(x) = 3x – 1, solve for x when f(x) = -7.
Answer:
x = -2
Step-by-step explanation:
Given f(x) = 3x – 1
f(x) = -7
3x-1 = -7
3x = -7+1
3x = -6
x = -2
Answer:
x = -22
Step-by-step explanation:
given:

Step-by-step explanation
The total area Room₁ and Room₂ = (A₁ + A₂) sq feet
= (180 + 144) sq feet
= 324 Sq feet.
In the given question
Length of the first room (l₁) = 18 feet
Width of the first room(w₁) = 10 feet
We know area of a rectangle is product of it's length and width.
∴ Area of the first room A₁ = (l₁ × w₁) sq feet
A₁ = (18 × 10) sq feet
A₁ = 180 sq feet.
Length of the second room (l₂) = 18 feet
Width of the second room (w₂) = 8 feet
∴ Area of the second room A₂ = (l₂ × w₂) sq feet
A₂ = (18 × 8) sq feet
A₂ = 144 sq feet.
∴The total area Room₁ and Room₂ = (A₁ + A₂) sq feet
= (180 + 144) sq feet
= 324 Sq feet.
Another way of finding the total area of the two rooms as we can see from the given figure both two rooms together form a square as the sides of the given sides which are 18 feet and (10 + 8) feet which is also 18 feet.
So, It is a square.
∴ Area of a square = (side)² (area of a square is product of
two adjacent sides)
Area = (18)² sq feet
= 324 sq feet.

Andre wants to make a scaled copy of Jada's drawing so the side that corresponds to 4 units in Jada’s polygon is 8 units in his scaled copy.
Scaled drawing shows representation of the correct sizes of the original object either being reduced or enlarged by a given amount
The correct response to Andre is that each length of the sides of Jada's drawing should be multiplied by two to make a scaled copy of the drawing
The reason the response is correct is as follows:
Question: The parts of the question that appear missing is as follows;
1. Andre makes the statement, in order to obtain the scaled copy, should he add 4 units to each of the dimensions of the sides of Jada's drawing
The question is, what should be the response to Andre
The response is as follows:
When making a scale drawing, it should be noted that the original drawing and the scaled copy of the drawing are to be similar figures. That is the ratio of their corresponding sides should be constant
The ratio of the corresponding sides of the scale drawing Andre wants to make is 8 units/(4 units) = 2 : 1
Therefore, the correct response is Andre should multiply each of the lengths of the sides of Jada's drawing by two to make a scaled drawing as follows
[tex]\begin{array}{|c|c|c|}\mathbf{Length \ on \ Jada's \ drawing}& \mathbf{Length \times 2 =} &\mathbf{Length \ of \ Andre's \ scaled \ copy}\\&&\\12& 12\times 2 =&24\\10& 10\times 2 =&20\\7& 7\times 2 =&14\\6& 6\times 2 =&12\\5& 5\times 2 =&10\\4& 4\times 2 =&8\end{array}\right][/tex]
The lengths of Andre's scaled copy are 8 units, 10 units, 12 units, 14 units, 20 units, and 24 units
