The bakery’s expenses and receipts will both total $_____ after ___ hours
PLEASE HELP ♡
Answers
Expenses and receipts will total $2800 after 200 hours.
==============================================================
Explanation:
x = number of hours
Ron spends $11 an hour for operating costs. He spends 11x dollars on top of the $600 he spent on the equipment. The cost expression is 11x+600
On the flip side, Ron earns (on average) $14 an hour from the receipts or revenue. Overall, he earns 14x dollars.
Often in business applications, the owner is curious when s/he will break even. This is the point where the profit is 0 dollars, ie when cost = revenue.
So we'll set the two expressions equal to one another and solve for x.
cost = revenue
11x+600 = 14x
600 = 14x-11x
600 = 3x
600/3 = x
200 = x
x = 200
At the 200 hour mark is when Ron is likely to break even.
This x value leads to:
cost = 11x+600 = 11*200+600 = 2200+600 = 2800 dollarsrevenue = 14x = 14*200 = 2800 dollarsWe get the same cost for each expression, helping to confirm that x = 200 is correct.
The bakery's expenses and receipts will total $2800 after 200 hours.

Since both sides are divisible by 3, you can simplify for the equation to be
m>=7
Next is to find the domain of the line graph. Since the sign is more than or equal to (>=), the circle is closed.
And since m is MORE THAN OR EQUAL TO, the section starts at 7 (closed circle), and continues after. Therefore, your answer will be the third selection.
Use the graph or table to find the equation that represents the relationship.

to get the equation of any straight line we only need two points off of it.

well, we have four points on the table, let's use a couple from it hmmm say (10 , -25) and (13 , -34)
[tex](\stackrel{x_1}{10}~,~\stackrel{y_1}{-25})\qquad (\stackrel{x_2}{13}~,~\stackrel{y_2}{-34}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-34}-\stackrel{y1}{(-25)}}}{\underset{run} {\underset{x_2}{13}-\underset{x_1}{10}}}\implies \cfrac{-34+25}{3}\implies \cfrac{-9}{3}\implies -3[/tex]

Find the center radius form for each circle having the given endpoints of a diameter.
22. (-4,5) and (6,-9)
26. ( 0,9) and (0,-9)
Answers
Answer:
22. [tex](x-1)^2+(y+2)^2=74[/tex]
26. [tex]x^2+y^2=81[/tex]
Step-by-step explanation:
The center of a circle is the midpoint of the diameter.
[tex]\textsf{midpoint}=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
(where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the endpoints of the diameter)
The radius of the circle is the distance between the center and an endpoint of the diameter.
[tex]\textsf{radius}=\sqrt{(a-x_1)^2+(b-y_1)^2}[/tex]
(where [tex](a,b)[/tex] is the center of the circle, and [tex](x_1,y_1)[/tex] is an endpoint of the diameter)
The center-radius form of a circle: [tex](x - a)^2+(y-b)^2=r^2[/tex]
(where (a, b) is the center and r is the radius)
Question 22
[tex]\textsf{Let }(x_1,y_1)=(-4.5)[/tex]
[tex]\textsf{Let }(x_2,y_2)=(6,-9)[/tex]
[tex]\textsf{center}=\left(\dfrac{-4+6}{2},\dfrac{5-9}{2}\right)=(1,-2)[/tex]
[tex]\textsf{radius}=\sqrt{(1+4)^2+(-2-5)^2}=\sqrt{74}[/tex]
⇒ equation of circle: [tex](x-1)^2+(y+2)^2=74[/tex]
Question 26
[tex]\textsf{Let }(x_1,y_1)=(0,9)[/tex]
[tex]\textsf{Let }(x_2,y_2)=(0,-9)[/tex]
[tex]\textsf{center}=\left(\dfrac{0+0}{2},\dfrac{9-9}{2}\right)=(0,0)[/tex]
[tex]\textsf{radius}=\sqrt{(0-0)^2+(0-9)^2}=9[/tex]

Angle between two vectors is equal to
Inverse cosine of their vectors dot product/ their magnitudes multiplied.
[tex]x = \cos {}^{ - 1} ( \frac{v \times v_{2} }{ |v| |v _{2} | } )[/tex]
Let first, find the dot product
[tex] < - 2,5 > \times < 4, - 3 > = - 8 - 15 = - 23[/tex]
Next we find magnitudes

[tex]29 = {x}^{2} [/tex]
[tex]x = \sqrt{29} [/tex]
[tex] {4}^{2} + {3}^{2} = {x}^{2} [/tex]

URGENT! Please help what is the median thank you math experts
Answers
Answer: The middle number in a data set when the data are put in order.
Answer and Step-by-step explanation:
To find the median of a set of numbers, you need to find what the number in the center is in a listed group of numbers. I'll use the example of these numbers:
6, 9, 5, 4, 3, 4, 2.5, 8, 0, 1, 5.
First, we need to organize the numbers in numerical order to find the median.
0, 1, 2.5, 3, 4, 4, 5, 5, 6, 8, 9.
It would be the most simple and helpful to cross out each number until we get our center number; the median. (I can't cross the numbers out, so I'll underline them instead.) When crossing out, both sides need to be full of equally crossed out numbers.
0, 1, 2.5, 3, 4, 4, 5, 5, 6, 8, 9.
The number in the center for this example problem is 4. Thus meaning that our median is 4.
Sometimes though, it is not always a whole number. Sometimes you'll have to find the median in between two numbers. For example, let's just say you got stuck between 4 and 5. Then the median for that set of data would be 4.5, because it is still in the middle of the two.
I hope that this helps, let me know if you have any more questions about this topic.

The intensity of the earthquake is an illustration of functions
The earthquake's magnitude is 7.88The earthquake is 0.9 times more than the earthquake that measured 5.3How to determine the magnitudeThe function is given as:
[tex]M=0.67 \log(0.37E)+1.46[/tex]
When the earthquake releases 10,500,000,000, we have:
[tex]M=0.67 \log(0.37*10500000000)+1.46[/tex]
Evaluate
[tex]M=7.8848919855[/tex]
Approximate
[tex]M=7.88[/tex]
Hence, the earthquake's magnitude is 7.88
Also, we have:
Earthquake 1 = 6.2
Earthquake 2 = 5.3
Calculate the difference (d)
[tex]d = 6.2-5.3[/tex]
[tex]d = 0.9[/tex]
Hence, the earthquake is 0.9 times more than the earthquake that measured 5.3

Answers
We are given that :
Height of cylinder = 21 cmRadius of cylinder = 24 cmTherefore, Volume :
➙ V = πr²h
➙ V = ( 22 / 7 ) × ( 24 )² × ( 21 )
➙ V = ( 22 / 7 ) × 576 × 21
➙ V = ( 22 × 576 × 21 ) / 7
➙ V = 266112 / 7

b) (x+1) + (3x+9) = 180
Combine like terms
4x + 10 = 180
4x = 170
divide both sides by 4
