Choose the abbreviation of the postulate or theorem that supports the conclusion that WAS NOT. Given: W = N, S = T, WA = NO.
SSS
SAS
ASA
AAS
Answer:
AAS I just answered this question and I got it right.
Final answer:
Given W=N, S=T, and WA=NO, no congruence theorems (SSS, SAS, ASA, AAS) demonstrate that triangles WAS and NOT are congruent, so the triangles are not congruent.
Explanation:
The student is asking which postulate or theorem supports the conclusion that triangle WAS is not congruent to triangle NOT. Given that W = N, S = T, and WA = NO, we can determine that the two triangles are not congruent. The four options provided are abbreviations for congruence theorems in geometry: Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), and Angle-Angle-Side (AAS).
However, none of these congruence theorems apply here because those would be used to prove congruence, not the lack thereof. In this case, if we look at the information given, we see that we have two pairs of sides and one pair of angles that are congruent. But the postulated congruent angles, A in triangle WAS and O in triangle NOT, are not included between the sides of the triangles that are known to be congruent. Therefore, none of the listed congruence postulates or theorems (SSS, SAS, ASA, AAS) can be used to conclude that the triangles are congruent. As a result, it can be concluded that the triangles are not congruent without needing to invoke a specific congruence theorem.

Find the sum the interior angle angle measures of a 17-gon
Answer:
2700 degrees.
Step-by-step explanation:
The external angles add up to 360 degrees
So 1 external angle in a regular 17-gon = 360/17
= 21.176 degrees
The internal angle = 180 - 21.176
= 158.824 degrees
Sum of internal angles = 158.824 * 17
= 2700 degrees.
Answer:
Step-by-step explanation:
Every closed curve called a polygon can be separated into a specific number of triangles. Then, because the sum of the interior angles of a triangle is 180, you take the number of triangles and multiply by 180 to get the sum of the interior angles of the n-gon. To find the number of triangles that exist within an n-gon, subtract 2 from the number of sides. If our figure is a 17-sided polygon, then the number of triangles within it is 17 - 2 = 15. 15 triangles, each with a sum of 180 for its angles. 15 * 180 = 2700.
Each central angle is 360 divided by 17 to get 21°10'35"
Each interior angle is 2700 divided by 17 to get 158°49'24"
A local farmer built a rectangular pen for her goats using 20 meters of fence. She used part of one side of her barn as one length of the rectangular pen. She maximized the area using 20 meters of fence. She then built a rectangular pen for her hogs using 24 meters of fence. She used part of one side of her barn as one length of the rectangular pen. The length of her pen was 2 meters more than the length of the goat pen. The width of her pen was 1 meter more than the width of the goat pen. How much larger is the hog pen than the goat pen?
The farmer's hog pen, with length of 12 meters and a width of 11 meters, is 32 square meters larger than the goat pen which has a length and width of 10 meters.
Explanation:First, let's establish the dimensions of both pens. For the goat pen, given that the farmer used 20 meters of fencing and one side was provided by the barn, the fence was distributed between two sides. If we assume these two sides to be equal (maximizing the area), each side would be 10 meters long.
On the other hand, the hog pen had 24 meters of fence distributed between two sides, with the length being 2 meters more than the goat pen and the width being 1 meter more than the goat pen. So, the length of the hog pen is 12 meters and width is 11 meters.
To find the difference in areas, we subtract the area of the goat pen from the hog pen. The area of a rectangle is calculated by multiplying the length by the width. For the goat pen, the area is 10m * 10m = 100m² and for the hog pen, the area is 12m * 11m = 132m². Thus, the area of the hog pen is 32m² larger than the goat pen.

Final answer:
It will take Alex 4 minutes to type 176 words at his current typing speed of 44 words per minute.
Explanation:
The question asks how long it would take for Alex to type 176 words if he can type 44 words in one minute. To find the answer, we utilize a simple rate calculation by dividing the total number of words (176) by Alex's typing speed (44 words per minute).
176 words ÷ 44 words/minute = 4 minutes
Therefore, it will take Alex exactly 4 minutes to type 176 words at the rate of 44 words per minute.
What is the equation of y=x^3 with the given transformations? Vertical stretch by a factor of 3, horizontal shift 4units to the right, vertical shift 3 units down
Answer:
y = 3(x -4)^3 -3
Step-by-step explanation:
As you know, the transformations are
g(x) = (vertical stretch factor) · f(x - (right shift)) +(vertical shift)
For the given transformations, the equation becomes ...
y = 3(x -4)^3 -3
The equation of y=x^3 with the given transformations is y = 3(x - 4)^3 - 3.
Explanation:The equation of y = x^3 after the given transformations is y = 3(x - 4)^3 - 3.
The vertical stretch by a factor of 3 means that all y-values will be multiplied by 3, so the equation becomes y = 3x^3.
The horizontal shift 4 units to the right means that x-values will be replaced by (x - 4), so the equation becomes y = 3(x - 4)^3.
The vertical shift 3 units down means that all y-values will be decreased by 3, so the equation becomes y = 3(x - 4)^3 - 3.

Step-by-step explanation:
Riley’s Rug Warehouse purchases rugs from the manufacturer for $82.00 each. The manager marks the rugs up 150% and then includes a 10% sales tax. How much much does a customer pay for 1 rug?
A customer will pay $225.5 for one rug.
Step-by-step explanation:
Given,
Purchase price of rug = $82.00
Mark up = 150%
Amount of mark up = 150% of purchase price
Amount of mark up = [tex]\frac{150}{100}*82[/tex]
Amount of mark up = 1.5*82 = $123
Price of rug after mark up = Purchase price + Mark up
Price of rug after mark up = 82+123 = $205
Sales tax = 10%
Amount of sales tax = 10% of price after markup
Amount of sales tax = [tex]\frac{10}{100}*205=\$20.5[/tex]
Selling price = Price after markup + Amount of sales tax
Selling price = 205+20.5 = $225.5
A customer will pay $225.5 for one rug.

x | f(x)
——————
-4 | 6
——————
-2 | 3
——————
0 | -1
——————
2 | -4
Answer:
Step-by-step explanation:
No, unless the function decides to follow a different pattern. See more explanation below.
Step-by-step explanation:
He is wrong, the table doesn't tell us what happens at x=6.
It does tell us the following:
1) When x=-4, f(x)=6.
2) When x=-2, f(x)=3.
3) When x=0, f(x)=-1.
4) When x=2, f(x)=-4.
So maybe he got it the x and f(x) value switched in his brain.
Because according to 1) x=-4 when f(x)=6.
If the points keep having x increase while y decreases, then every x>2 will have a y less than -4 correspond to it.
Rob's determination that the function X = 6 when f(x) = -4 appears to be correct based on the provided data.
What is equation?An equation is a mathematical statement that shows that two expressions are equal.
It typically includes variables, constants, and mathematical operations and is used to solve for unknown values.
Rob seems to be correct. If you look at the table of values:
x | f(x)
-4 | 6
-2 | 3
0 | -1
2 | -4
When x = 6,
we find that the function f(x) = -4 (as indicated in the last row of the table).
So, Rob's determination that X = 6 when f(x) = -4 appears to be correct based on the provided data.

11 dm = 1.1 meters
15 mm = 0.015 meters
b)
Volume = 0.005775 cubic meters
Mass = 15.5925 kilograms
Step-by-step explanation:
1.
We know
Density = Mass/Volume
Given
Mass = 90 kg
Volume = 0.075 cubic meters
The SI unit for density is kilograms per cubic meters. Our dimensions are just that, so we just need to plug in the numbers into the formula and get our answer. Shown below:
Density = [tex]\frac{90}{0.075}=1200 \ kg/m^3[/tex]
The Density of asphalt block = [tex]1200 \ kg/m^3[/tex]
2.
a)
We need to express 35cm, 11dm, and 15mm in meters
We know
100 cm = 1 meters, so
35 cm = 35/100 = 0.35 meters
We know 1 dm = 0.1 meters, so
11 dm * 0.1 = 1.1 meters
We know, 1mm = 0.001 meters, so
15 mm * 0.001 = 0.015 meters
b)
Volume of the Slab is length * width * height, in meters, that would be:
Volume = 0.35 * 1.1 * 0.015 = 0.005775 cubic meters
THe mass would be found by the formula:
Density = Mass/Volume
2700 = Mass/0.005775
Mass = 0.005775 * 2700 = 15.5925 kilograms

There are 6 solutions to the polynomial over the complex number system.
The given equation is 3[tex]x^{6}[/tex]-x³-4x²+5x+52=0.
What is the complex number system of a polynomial?The Fundamental Theorem of Algebra states that every polynomial of degree one or greater has at least one root in the complex number system. A further theorem, in some cases referred to as the Linear Factorization Theorem, states that a polynomial of degree n has exactly n linear factors, and each can be written in the form (x - c), where c is a root. These n complex roots are counted with multiplicity.
In polynomials, the number of roots or highest power is equal to the degree of the polynomial.
Here, 3[tex]x^{6}[/tex]-x³-4x²+5x+52=0.

Olivia bought a piece of ribbon priced at $0.56 per yard. The total cost was $1.54. How many yards did she buy?
Answer:
2.75 or 2 3/4
Step-by-step explanation:
Divide the total cost by the price of each ribbon.
$1.54 ÷ $0.56/yard = 2.75 yards
If the answer needs to be in mixed fractional form, convert 0.75 to a fraction.
3/4 = 0.75
The fraction form of 2.75 is 2 3/4.
Therefore Olivia bought 2 3/4 yards of ribbon.
A line containing the points (3,0) and (-2,-2) is graphed on a coordinate grid. Which of these
points is a solution to the equation that represents this line?
(-12,-6)
(-4,-3)
(0.5,-1)
(5,0.8)
(9,3)
(18,6)
Answer: (-12,-6)
Step-by-step explanation:
If we already have two points of the line, we can find its slope ([tex]m[/tex]), its intersection with the y-axis ([tex]b[/tex]), hence its equation:
Point 1: [tex](x_{1},y_{1})=(3,0)[/tex]
Point 2: [tex](x_{2},y_{2})=(-2,-2)[/tex]
Slope equation:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m=\frac{-2-0}{-2-3}[/tex]
[tex]m=\frac{2}{5}[/tex] This is the slope of the line
Now, the equation of the line is:
[tex]y=mx+b[/tex]
We already know the slope, now we have to find [tex]b[/tex] with any of the given points. Let's choose Point 1: [tex](x_{1},y_{1})=(3,0)[/tex]
[tex]0=\frac{2}{5}(3)+b[/tex]
Isolating [tex]b[/tex]:
[tex]b=-\frac{6}{5}[/tex]
Then, the equation of the line is:
[tex]y=\frac{2}{5} x-\frac{6}{5}[/tex]
With this equation we can find which point is a solution. Let's begin with the first point (-12,-6):
[tex]-6=\frac{2}{5} (-12)-\frac{6}{5}[/tex]
[tex]-6=-\frac{24}{5} -\frac{6}{5}[/tex]
[tex]-6=-6[/tex] Since both sides of the equation are equal, (-12,-6) is the point that fulfills the solution of the equation.
