Your 6.50 kW air conditioner is used for a total of 125 days (24 hours per day). Assume the cost per kWh is 0.0825 determined the cost of air conditioning for one year.
Answer:
Air conditioners are rated by the number of British Thermal Units (BTU) of heat they can remove per hour. Another common rating term for air conditioning size is the "ton," which is 12,000 BTU per hour.
Each air conditioner has an energy-efficiency rating that lists how many BTUs per hour are removed or “pulled out” for each watt of power it draws.
The efficiency rating for room conditioners is the Energy Efficiency Ratio, or EER.
The efficiency rating for central air conditioners, is the Seasonal Energy Efficiency Ratio, or SEER.
These ratings are posted on an Energy Guide Label, which must be conspicuously attached to all new air conditioners. Energy Star-labeled appliances mean that they have high EER and SEER ratings
Is 12/15 closest to 0, 1/2 or 1
Answer:

Step-by-step explanation:
[tex]\frac{1}{2}[/tex] = [tex]\frac{7.5}{15}[/tex]
1 = [tex]\frac{15}{15}[/tex]
which is 12 closer to?
7.5 or 15 ?
15 of course
Answer:
1
Step-by-step explanation:
12/15 = 0.8
0=0.0
1/2=0.5
1=1.0
0<0.5<0.8<1
So now it is in between 0.5 and 0.8 and it is closer to 1 as it is only 0.2 away, 0.5 is 0.3 away.

I WILL AWARD BRAINLIEST
Answer:
Option A is the correct answer.
Step-by-step explanation:
First, look at the second equation. Get s and r onto the same side.
For simplicity, I will use x for r and y for s
Multiply the first equation by 3, and multiply the second equation by -4.
3(2x+8y=−4)
−4(7x+6y=8)
Becomes:
6x+24y=−12
−28x−24y=−32
Add these equations to eliminate y:
−22x=−44
x=2=r
Now we substitute this back in for the original equation
(2)(2)+8y=−4
8y=-8
y=-1=s
Option A is the correct answer.
What is the value of x in the figure?
Enter your answer in the box.
Answer:
the answer is 29° because you have to subtract 61 from 90 and you will get 29.
x = 29°
Answer:
The answer is 29°
Step-by-step explanation:
We are given a figure,
Here, we know that on straight line the sum of all angles is equal to 180°
So,
x + 90° + 61° = 180°
x + 151° = 180°
x = 151° – 151° = 180° – 151°
x = 29°
Thus, The value of x is 29°
For Verification;x + 90° + 61° = 180°
29° + 90° + 61° = 180°
180° = 180°
L.H.S = R.H.S
Hence Verified!

Which of the following number sentences illustrates the associative property of multiplication?
8x9 = 9x8
2 x (1 x 9) = (2 x 1) (2 x 9)
(3 x 8) x 6 = 3 c (8 x 6)
1x 15 = 15
Answer: Choice C
(3 x 8) x 6 = 3 x (8 x 6)
=================================================
Explanation:
The associative property in general is
(a x b) x c = a x (b x c)
where the x stands for the multiplication symbol.
The a,b,c is in the same order for both sides, but grouped in slightly different ways with the parenthesis.
Plug in a = 3, b = 8, c = 6 to arrive at (3 x 8) x 6 = 3 x (8 x 6)

Approximately how many feet of protective material does Jada need?
Use 3.14 for π.
Enter your answer as a decimal in the box.
feet
Answer:
47,1
Step-by-step explanation:
it is because when you multiply 3,14 by 15 you get your answer as 47,1 and it is a decimal
Using Multiplication, Jada need 47.1 feet of protective material around the rim of the pool.
What is multiplication?Multiplication is the "method of finding product of two or more numbers".
According to the question,
A circular swimming pool has a diameter of 15 feet.
In order to find how many feet of protective material jada need:
Formula for area of circle = πr² where 'r' is the radius of the circle.
Diameter = r²
= (3.14) (15) [π = .14]
= 47.1
Hence, Jada need 47.1 feet of protective material around the rim of the pool.

Which is greater: 25% of 15 or 15% of 25? Explain your reasoning using mathematical evidence or visual models
Answer:
15% of 25
Step-by-step explanation:
Given the following questions:
25% of 15
15% of 25
We find the answer by using the formula to calculate percentage for both questions.
Question one:
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{25\times15}{100} =25\times15=375\div100=3.75[/tex]
[tex]=3.75[/tex]
25% of 15 is 3.75
Question two:
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{15\times 25}{100}=15\times25=375\div100=3.75[/tex]
[tex]=3.75[/tex]
15% of 25 is 3.75
Finally:
[tex]3.75=3.75[/tex]
[tex]15-3.75=11.25[/tex]
[tex]25-3.75=21.25[/tex]
[tex]11.25 < 21.25[/tex]
Which means 15% of 25 is "greater than" 25% of 15.

Select the correct answer. Which equation is true for the value a = 7? A. a + 2(a – 3) = 15 B. 4a – 4(14 – a) = 24 C. 2a + 47 = 105 D. 3a + 2(a – 3) = 34 E. 4a – 2a = 18
100 POINTS!!!!!!
Answer:
[A]. a + 2(a – 3) = 15
Step-by-step explanation:
To See which equation is true for the value a = 7 Solve all of it.
Start with [A]
[A] a + 2(a – 3) = 15
7+2(7-3)=15
Hence,this is True.
Next ,[B]
[B] 4a-4(14-a)=24
4(7)-4(24-7)= -40
Hence, this is False.
Then, we have [C]
[C] 2a + 47 = 105
2(7) + 47 =61
Hence, this is False.
Now, We have [D]
[D] 3a+2(a-3)=34
3(7)+2(7-3)=29
Hence, this is False.
Lastly, We have [E]
[E] 4a-2a=18
4(7)-2(7)=14
Hence, this is False.
Thus, Correct Answer = [A].a + 2(a – 3) = 15

Can someone please explain how to get the answer I've watched multiple videos on implicit derivatives and I still cant figure it out.
We're given the implicit equation
x² + 2x + y² - 4y = 12
where "implicit" means that one of the variables is considered a function of the other. In this case, the variable y = y(x) depends on the value of the variable x - in other words, the possible values of y are implied by the value of x. We then say that this equation defines y as an implicit function of x.
We're also given the implicit derivative,
dy/dx = (-2x - 2)/(2y - 4)
which tells us the rate of change y as a function of both x and y. The value of dy/dx corresponds to the slope of the tangent line to the curve defined by the implicit equation above at some point (x, y).
The tangent line is horizontal when its slope is zero. This happens when
(-2x - 2)/(2y - 4) = 0
If y ≠ 2, then we can eliminate the denominator and we're left with
-2x - 2 = 0
Solve for x :
-2x = 2
x = -1
This tells us that the points on the curve with x-coordinate -1 have a tangent line to the curve that is horizontal.
The tangent line is vertical when its slope is undefined/infinite, or equivalently when the denominator of dy/dx is zero:
2y - 4 = 0
Solve for y :
2y = 4
y = 2
So any point on the curve with y-coordinate 2 will have a tangent line there that is vertical.
By completing the square in the implicit equation, we can easily identify where these points are located.
x² + 2x + y² - 4y = 12
x² + 2x + 1 + y² - 4y + 4 = 17
(x + 1)² + (y - 2)² = 17
This equation defines a circle centered at (-1, 2) with radius √17. When x = -1, we have
(y - 2)² = 17 ⇒ y = 2 ± √17
and when y = 2, we have
(x + 1)² = 17 ⇒ x = -1 ± √17
See the attached plot to see the circle and the tangents at these points.
