Which of the following best describes XYZ
D. Inscribed angle
Step-by-step explanation:An inscribed angle has a vertex on the circumference. For any arc, every inscribed angle is exactly half of the central angle. In other words, if the central angle is [tex]x^{\circ}[/tex] and the inscribed angles is [tex]y^{\circ}[/tex], then it is true that:
[tex]y^{\circ}=\frac{x^{\circ}}{2}[/tex]
In this problem [tex]y^{\circ}=36^{\circ}[/tex], then the central angle is [tex]x^{\circ}=2y^{\circ} \ \therefore x^{\circ}=2(36^{\circ}) \therefore x^{\circ}=72^{\circ}[/tex]
Answer:

On Monday 4 bricklayers took 3 hours to lay a total of 4200 bricks.
On Tuesday there are only 2 bricklayers.
Work out how many hours it will take the 2 bricklayers to lay a total of 3150 bricks
The answer is:
It will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.
Why?From the statement, we know that on Monday, bricklayers took 3 hours to lay a total of 4200 bricks.
So, we have that the rate of the four bricklayers is given by the following equation:
[tex]Production=Rate*Time\\\\Rate=\frac{Production}{time}[/tex]
[tex]Rate=\frac{4200bricks}{3hours}=\frac{1400bricks}{hour}[/tex]
Therefore, we have that the rate of the four bricklayers is 1400 bricks per hour, meaning that each bricklayer can lay 350 bricks per hour.
Now, to calculate how many hours it will take to the 2 bricklayers to lay a total of 3150, we need to divide the calculated rate (for bricklayers) by two, since there are only 2 bricklayers working on Tuesday.
So, calculating the time, we have:
[tex]Production=\frac{Rate}{2}*Time[/tex]
[tex]3150bricks=\frac{\frac{1400bricks}{hour}}{2}*Time[/tex]
[tex]3150bricks*2*\frac{1hour}{1400bricks}=Time[/tex]
[tex]6300bricks*\frac{1hour}{1400bricks}=Time[/tex]
[tex]Time=4.5hours[/tex]
Hence, we have that it will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.
Have a nice day!
Given the rate of work from Monday, each bricklayer can lay 350 bricks an hour. Therefore, 2 bricklayers can lay 700 bricks an hour. It will take them approximately 4.5 hours to lay 3150 bricks.
Explanation:First, we need to find out the rate of work done by each bricklayer. On Monday, 4 bricklayers took 3 hours to lay a total of 4200 bricks. Therefore, each bricklayer can lay 4200 bricks divided by 4 bricklayers divided by 3 hours, which equals 350 bricks per hour. So, one bricklayer can lay 350 bricks an hour.
On Tuesday, there are only 2 bricklayers, and they need to lay a total of 3150 bricks. Since each bricklayer can lay 350 bricks an hour, two bricklayers can lay 700 bricks an hour. To find out the time it will take to lay 3150 bricks, we divide 3150 bricks by the 700 bricks that two bricklayers can lay in an hour. This equals to approximately 4.5 hours.

The circle given by : x^2 + y^2 - 6y - 12 = 0 can be written as:
x^2 + (y - k)^2 = 21.
What is the value of k in this equation?
Step-by-step explanation:
Given equation of circle is,
[tex] {x}^{2} + {y}^{2} - 6y - 12 = 0 \\ by \: compairing \: it \: with \: \\ {x}^{2} + {y}^{2} + 2gx + 2fy = 0 \: we \: get \\2 g = 0 \: or \: g = 0 \\ 2f= - 6 \\ or \: f= - 3 \\ c = - 12[/tex]
again the another form of circle is,

Allison is closing on a house on september 17. The buyer owns the property on the day of the closing. The selling price of the gone is $200,500. Allison was accepted for a 25-year fixed-rate mortgage for $185,000 at 6.25% interest. The seller has paid $2,560.43 in property taxes for the coming year. How much will Allison owe in prorated taxes and interest.
Answer:
197,500
Step-by-step explanation:
200500*25-184000/6.25-2560.43=4980499.57 Which rounds to 197,500.
Allison owes approximately $1,380.50 in prorated taxes and interest for the property she's closing on September 17.
To calculate the prorated taxes and interest that Allison owes, we need to break down the calculation into two parts: prorated property taxes and prorated interest.
1. **Prorated Property Taxes:**
- Allison is closing on September 17, which means she will own the property for 106 days of the year (September 17 to December 31).
- The seller has already paid $2,560.43 in property taxes for the entire year.
- To calculate Allison's portion of the property taxes, we need to divide the seller's payment by the number of days in the year and then multiply by the number of days Allison will own the property.
Prorated Property Taxes = Seller's Property Tax Payment/
Days in Year × Days Allison Owns the Property
[tex]\[ \text{Prorated Property Taxes} = \frac{2,560.43}{365} \times 106 \][/tex]
[tex]\[ \text{Prorated Property Taxes} = \frac{2,560.43}{365} \times 106 = 741.12 \][/tex]
2. **Prorated Interest:**
- Allison is taking out a 25-year fixed-rate mortgage for $185,000 at 6.25% interest.
- To calculate the prorated interest, we need to find out how much interest Allison will owe for the remaining days of September.
Daily Interest Rate [tex]$=\frac{\text { Annual Interest Rate }}{\text { Days in Year }}=\frac{6.25 \%}{365}$[/tex]
Prorated Interest for September = [tex]Loan Amount $\times$ Daily Interest Rate $\times$ Number of Days in September[/tex]
[tex]\[ \text{Prorated Interest for September} = 185,000 \times \frac{6.25\%}{365} \times 14 \][/tex]
[tex]\[ \text{Prorated Interest for September} \approx 639.38 \][/tex]
Now, let's add up the prorated property taxes and prorated interest:
[tex]\[\text{Total Prorated Taxes and Interest} = \text{Prorated Property Taxes} + \text{Prorated Interest for September}\][/tex]
[tex]\[\text{Total Prorated Taxes and Interest} = 741.12 + 639.38\][/tex]
[tex]\[\text{Total Prorated Taxes and Interest} = 1380.50\][/tex]
So, Allison will owe approximately $1,380.50 in prorated taxes and interest.

Y=-2/5x -1 is the answer I believe, if anything check Photomath, that should be the right slope double check the y-intercept by plugging it in with your points provided to u
Answer:y = -2x + 7
Step-by-step explanation:
The equation of a straight line when two points are given is y - y1 = m(x - x1) but m is gradient which is y2 - y1 / x2 - x1
Substitute the points (3 ,1 ) and (7 , -7)
To the gradient equation and solve for the gradient which is m = -2 .Now with the gradient and the first point (3 , 1) solve for the equation
:• y - 1 = -2(x -3 )
y - 1 = -2x +6
. y = -2x + 7
8) Solve 4^(x - 2)= 8^6
A)5
B)8
C)10

For this case we have the following equation:
[tex]4 ^ {(x-2)} = 8 ^ 6[/tex]
We must create equivalent expressions in the equation, so that they have equal bases:
[tex]2 ^ {2 * (x-2)} = 2 ^ {3 * 6}[/tex]
If the bases are the same, then the two expressions are only equal if the exponents are equal:
[tex]2 (x-2) = 3 * 6\\2 (x-2) = 18\\2x-4 = 18\\2x = 18 + 4\\2x = 22\\x = \frac {22} {2}\\x = 11[/tex]
Answer:
[tex]x = 11[/tex]
Option D
Answer: OPTION D
Step-by-step explanation:
You need to remember the following:
[tex]a^x=a^y\\x=y[/tex]
Then, you must descompose 4 and 8 into their prime factors:
[tex]4=2*2=2^2\\8=2*2*2=2^3[/tex]
Rewriting the expression:
[tex]2^{2(x-2)}=2^{3(6)}[/tex]
Now you get:
[tex]2(x-2)=3(6)[/tex]
Finally, you must solve for the variable "x".
Therefore, you get the following result:
[tex]2x-4=18\\2x=22\\x=11[/tex]
A wall of a building is made from blocks that are each one cubic foot the wall is 6 feet high and 6 feet wide. a window is made by removing some blocks as shown below the window is 2 feet high by 2 feet wide.what is the value of the wall after the window is made?
The required value of the wall after the window is made is 32 cubic feet.
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
Here,
The total number of cubic feet in the wall before the window is made is,
6 feet (height) × 6 feet (width) = 36 cubic feet.
The window is 2 feet high and 2 feet wide, so its area is:
2 feet (height) × 2 feet (width) = 4 square feet.
To find the number of cubic feet removed to make the window, we simply multiply the area of the window by the depth of the wall, which is 1 foot:
4 square feet × 1 foot = 4 cubic feet.
Therefore, the total number of cubic feet in the wall after the window is made is,
36 cubic feet - 4 cubic feet = 32 cubic feet.
So the value of the wall after the window is made is 32 cubic feet.

O
C. 0.10, because 6 of the 60 days were clear
O
D. 0.20, because 6 of the 30 days were clear
The probability that it will be a clear day in San Antonio in May is 0.57 or 57%, calculated by dividing the number of clear days (17) by the total number of days in May (30).
Explanation:In order to determine the probability of a clear day in San Antonio in May, we need to use the given data. From option OA, it is stated that there are 17 clear days out of 30. Probability is calculated by dividing the number of favorable outcomes (clear days) by the total number of outcomes (total days in May).
So, if we divide 17 (the number of clear days) by 30 (the total number of days in May), we get the probability as 0.57 after rounding to two decimal places which matches option OA.Therefore, the probability that it will be clear in San Antonio in May is 0.57 or 57%.

Scores on the GRE (Graduate Record Examination) are normally distributed with a mean of 600 and a standard deviation of 120. Use the 68 dash 95 dash 99.7 Rule to find the percentage of people taking the test who score between 240 and 960.
Answer:
99.7%
Step-by-step explanation:
The 68-95-99.7 rule refers to what percentage of data is contained within ranges a certain distance from the mean.
68% of the data lies within one standard deviation of the mean
95% lies within two standard deviations, and
99.7% lies within three standard deviations.
Our mean here is 600, and our standard deviation is 120, so those ranges would be:
480-720 for 1 standard deviation
360-840 for 2 standard deviations, and
240-960 for 3.
Our given range is 240 to 960, three standard deviations from the mean, so the 68-95-99.7 rule tells us that this range contains 99.7% of the people.
According to the empirical rule, approximately 99.7% of people taking the GRE score between 240 and 960.
The student is asking for the percentage of people taking the GRE who score between 240 and 960 using the 68-95-99.7 Rule (also known as the empirical rule). This rule applies to normally distributed data and indicates that approximately 68% of data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.
For the GRE, with a mean score of 600 and standard deviation of 120, one standard deviation range is from 480 to 720, two standard deviations is from 360 to 840, and three standard deviations is from 240 to 960. Using this rule:
68% of the scores fall between 480 (600-120) and 720 (600+120).
95% of the scores fall between 360 (600-2*120) and 840 (600+2*120).
99.7% of the scores fall between 240 (600-3*120) and 960 (600+3*120).
Hence, according to the empirical rule, approximately 99.7% of people taking the GRE score between 240 and 960.

The polynomial of degree 3, P(x), has a root of. multiplicity 2 at x=1 and a roof of multiplicity 1 at x= -3. the y- intercept is y= 2.1. Find a formula for P(x)
[tex]P(x)[/tex] has degree 3, so it takes the general form
[tex]P(x)=ax^3+bx^2+cx+d[/tex]
It has a root [tex]x=1[/tex] of multiplicity 2, which means [tex](x-1)^2[/tex] divides [tex]P(x)[/tex] exactly, and it has a root of [tex]x=-3[/tex] of multiplicity 1 so that [tex]x+3[/tex] also is a factor. So
[tex]P(x)=a(x-1)^2(x+3)[/tex]
Expanding this gives
[tex]P(x)=a(x^3+x^2-5x+3)=ax^3+ax^2-5ax+3a[/tex]
[tex]\implies\begin{cases}a=b\\-5a=c\\3a=d\end{cases}[/tex]
The [tex]y[/tex]-intercept occurs for [tex]x=0[/tex], for which we have
[tex]P(0)=d=2.1[/tex]
Then
[tex]3a=d\implies a=0.7[/tex]
[tex]a=b\implies b=0.7[/tex]

was the markup?
$0.29
$1.42
$1.29
$0.42
$10.00
10.00 was the markup
Ellen's markup on the rose bushes is calculated by subtracting the wholesale price from the retail price, resulting in a markup of $10.00.
The question asks to calculate the markup of rose bushes that were bought at a wholesale price and then sold at a retail price.
To find the markup, we subtract the wholesale price from the retail price: Retail Price - Wholesale Price = Markup.
In this case, Ellen bought the rose bushes at a wholesale price of $24 and the retail price was $34.
So, the markup calculation would be:
= $34 - $24 = $10.
Therefore, the markup on the rose bushes is $10.00.

[tex]0=p^2-3p+2[/tex]
[tex]0=p^2-1p-2p+2[/tex]
[tex]0=(p-1)(p-2)[/tex]
[tex]0=(p-1)[/tex] or [tex]0=(p-2)[/tex]
[tex]1=p[/tex] or [tex]2=p[/tex]
But p=1 will make denominator 0 and make the problem not defined.
Hence final answer is p=2
