Xerxes, Murray, Stav, Zeke, Cam, and Georgia are invited to a dinner party. They arrive in a random order and all arrive at different times. What is the probability that Xeres arrives first?
Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
There are "6" people in total.
They can come at any place and at any time. All of them have equal chances of arriving at any place.
Similarly,
Everyone has the same chances of coming first.
Hence, the probability of Xerxes coming first is 1 out of 6 people
Hence,
Probability (Xerxes coming first) = 1/6
The answer is [tex]\frac{1}{6}[/tex]

The sequence of transformations will verify that △EFG and △E'F'G' are congruent is; C) △EFG is moved onto △E'F'G' after rotating 270 degrees counterclockwise around the origin, and then reflecting across the x-axis
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs), etc.
For triangle △EFG and △E'F'G' to be congruent, we must first rotate 180° counterclockwise around the origin and then move EFG onto E'F'G'H'.
This proof of congruency is reflected across the y-axis.

One day a student comes to school sick and infects two students. The next day each of the two infected students come to school and infect four additional students. At this rate, how many days will it take to infect all 500 students in the school? Create an equation.
Answer:
2x=500
Step-by-step explanation:
Let x be the number of days.
Since there is a pattern, that 1 person is infected and infects two. Then two infects 4.
So it will be 2x. Since everyday it goes up.
Then, since there are 500 students in the school and the question asks for how many days, it will equal 500.
Identify the equation of the circle D with center D(−8,−1) and radius 3.
Answer:
(h+8)^2 + ( y +1)^2 = 9
Step-by-step explanation:
The equation of a circle can be written as
(x-h) ^2 +(y-k) ^2 = r^2
where (h,k) is the center and r is the radius
(h- -8)^2 + ( y - -1)^2 = 3^2
(h+8)^2 + ( y +1)^2 = 3^2
(h+8)^2 + ( y +1)^2 = 9
Answer:
(x + 8)² + (y + 1)² = 9
Step-by-step explanation:
Equation of a circle
(x - h)² + (y - k)² = r²
(x - -8)² + (y - -1)² = 3²
(x + 8)² + (y + 1)² = 9

Can soembody help me answer this please. PLEASE BE QUICK AND RIGHT !!!
Answer:
A, D, and G
Step-by-step explanation:
Let's try each of the answer choices, one by one.
A) Plug x = 2 into each expression and see what we get.
7x + 4 = 7 * 2 + 4 = 14 + 4 = 18
3x + 5 + 4x - 1 = 3 * 2 + 5 + 4 * 2 - 1 = 6 + 5 + 8 - 1 = 18
Since they're both 18 when x = 2, A is true.
B) The statement says that the expressions are only equal for x = 4 and x = 8, but as we saw from A, they're also equal when x = 2, so B is wrong.
C) Let's try to find a counterexample for this by plugging in an odd number into each expression, like 1:
7x + 4 = 7 * 1 + 4 = 7 + 4 = 11
3x + 5 + 4x - 1 = 3 * 1 + 5 + 4 * 1 - 1 = 3 + 5 + 4 - 1 = 11
We see that these two expressions are equivalent when x = 1, which is an odd number, so this contradicts the statement that they're only equal when x is even. C is wrong.
D) Let's combine like terms for the expression 3x + 5 + 4x - 1:
3x + 4x + 5 - 1 = 7x + 4
Notice that this is the exact same expression as the first one, which is 7x + 4 so that means for any x, these two expressions will always be the same. D is thus true.
E) This is not true because it's possible that two expressions aren't equivalent but have the same value for a certain odd number and a certain even number. E is incorrect.
F) Obviously, if the two expressions are equivalent, they will give the same answer for any input of x, including when x = 0, so F is wrong.
G) Again, the two expressions will always be equal, including when x = 8, so this statement is true.
The answers are A, D, and G.
Hope this helps!
Answer:
Statement 1
Statement 4
Statement 7
Step-by-step explanation:
(1) 7x + 4
(2) 3x + 5 + 4x - 1 = 7x + 4
The two are identical hence equivalent for all x

Answer:
4.24
Step-by-step explanation:
you should use the pythagorean theorem to solve this!
a^2 + b ^2 = c^2
3^2 + 3^2 = c^2 (i got 3 because it goes down three, and over three)
9 + 9 = c^2
18 = c^2
the square root of 18 is 4.24
therefore, the distance between C and D is 4.24.

The pilot of a glider plane wants to estimate his altitude. He picks a landmark ahead and measures the angle of depression to be 20 degrees. He flies another 800 feet towards the landmark, remaining at the same altitude. The angle of depression from his new location to the same landmark is now 21.4 degrees. What is the glider's altitude?
Answer:
4,000 ftExplanation:
The figure attached shows sketches the situation described.
You have two right triangles.
For the right triangle with the plane on the position A, you can write:
tan(20º) = H/(800 + x)⇒ H = (800 + x) tan(20º)
For the right triangle with the plane on the position B, you can write:
tan(21.4º) = H/x⇒ H = x tan(21.4º)
To solve, equal both equations:
x tan(21.4º) = (800 + x) tan(20º)x tan(21.4º) = 800 tan(20º) + x tan(20º)x = 800 tan(20º) / ( tan(21.4º) - tan(20º) )x = 10,426.9 feetSubstitute in the equation H = x tan(21.4º)
H = 10,426.899856 × tan(21.4º) = 4,086 ftRounding to one signficant figure that is 4,000 ft.

Answer:
Bottom left graph
Step-by-step explanation:
Since the y-coordinates are the same, but the x-coordinates are opposites, it is a reflection across the y axis.
Therefore, the bottom left graph is correct.
Answer: The Bottom Left Graph
Step-by-step explanation:
The Y coordinates are the same number, therefore, when you find the coordinates of the points, the y must be equal, making them the same height on a graph. The X coordinates on the graph must be opposites, therefore, the two dots have to be equidistant from the Y axis. The only graph that has two dots at the same height and is equidistant from the Y axis is the graph at the bottom Left Corner.

=====================================================
Explanation:
Each circle has a radius of 'a'. So r = a.
The area of each circle is pi*r^2 = pi*a^2
The area of each square with side length b is b^2
The two stacks have the same volume only when the circle area is equal to the square area, so whenever pi*a^2 = b^2 is true.
Solving for b leads to b = sqrt(pi*a^2) = sqrt(pi)*a
The stacks must also be the same height for the volumes to be the same, so m = n as well.

The surface area of a piece of paper is 137 cm2. Use the fact that 10 mm = 1 cm to convert this area to mm2. Give your answer as a number. Do not type the units in the space below.
Solution:
surface area of a piece of paper = 137 sq cm
Use the fact that 10 mm = 1 cm to convert this area to mm^2
[tex]1\ cm = 10\ mm[/tex]
Then,
[tex]1\ cm^2 = 100\ mm^2[/tex]
Convert 137 sq cm to sq mm
[tex]137\ cm^2 = 137 \times 100\ mm^2\\\\137\ cm^2 = 13700\ mm^2[/tex]
Thus, surface area of a piece of paper is [tex]13700\ mm^2[/tex]
To convert the surface area of a piece of paper from cm² to mm², use the conversion factor 1 cm² = 100 mm².
Explanation:To convert the surface area of a piece of paper from square centimeters (cm²) to square millimeters (mm²), we can use the conversion factor that 10 mm = 1 cm. Since we are given the surface area as 137 cm², we can multiply it by the conversion factor to get the value in mm².
Conversion factor: 1 cm² = (10 mm)² = 100 mm²
Therefore, the surface area of the paper in mm² is 137 cm² x 100 mm²/cm² = 13700 mm².

What is the correct answer in terms of pi
Answer:
volume of a cone = 2.82πinches³( nearest hundredth)
Step-by-step explanation:
given that the diameter of a cone = 2 3/8
diameter = radius x 2
radius = diameter /2
radius = 19/8/2 = 1.1875
height of the cone = 6inches
volume of the cone = ?
recall that the formulae for calculating the volume of a cone = πr² h/3
volume of a cone = πr² h/3
volume of a cone = π (1.1875)² x 6/3
volume of a cone = π1.410 x 2
volume of a cone = 2.8203πinches³
volume of a cone = 2.82πinches³( nearest hundredth)
Given a triangle with side lengths of a, b, and c, where c is the longest side, which statement is true?
If b2 + c2 = a2, then the triangle is a right triangle.
If a2 + c2 = b2, then the triangle is a right triangle.
If a2 + b2 =c2, then the triangle is a right triangle.
If a2 = b2 = c2, then the triangle is a right triangle.
Answer:
It is C. If a2 + b2 =c2, then the triangle is a right triangle.
Step-by-step explanation:
If a triangle has side lengths a, b, and c, where c is the longest side, then the statement "If a2 + b2 = c2, then the triangle is a right triangle", the correct option is C.
What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
|AC|^2 = |AB|^2 + |BC|^2
We are given that;
Sides of triangle are a, b and c
Now,
This statement is known as the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs (a and b) is equal to the square of the length of the hypotenuse (c).
Conversely, if a triangle satisfies the Pythagorean Theorem, then it is a right triangle.
Therefore, by Pythagoras theorem the answer will be a2 + b2 = c2, then the triangle is a right triangle.
