What is y, the distance between points r and r'? 3 units 4 units 6 units 9 units
By applying dilatation and congruency theorem, it can be concluded that the distance between points R and R' is 3 units (option A).
Dilation is a transformation of a geometric shape, either becoming larger or smaller, without changing the original shape using a certain scale factor.
Two shapes are said to be congruent if a pair of corresponding sides have the same ratio and the corresponding angles have the same measure.
From the problem we obtained the following information:
QR is dilated to create Q'R' ⇒ QR // Q'R'
The dilatation factor is 1.5 ⇒ Q'R'/QR = 1.5
Now we look at the ΔTRQ and ΔTR'Q':
QR // Q'R'
∠TRQ = ∠TR'Q'
So ΔTRQ is congruent to ΔTR'Q' and TR'/TR = Q'R'/QR
Now we can calculate y using this equation:
TR'/TR = Q'R'/QR
(6 + y) / 6 = 1.5
6 + y = 9
y = 3
Thus, the distance between points R and R' is 3 units.

Factor completely
4x^2 - 18x - 36
Answer: 2(2x + 3)(x - 6)
Step-by-step explanation: For any factoring problem you do, your first
task will be to determine if a GCF exists for the original polynomial.
If a GCF does exist, it must be factored out as the first step to the problem.
In the problem you see here, the 3 terms in
the original polynomial have a GCF of 2.
So a 2 must be factored out as your first step.
This leaves you with 2(2x² - 9x - 18).
This does not make your life a whole lot easier however
because you still have a coefficient on the x squared term.
Factoring from here, you get 2(2x + 3)(x - 6).
Answer:
2(x - 6)(2x + 3)
Step-by-step explanation:
There are a few steps to factoring depending on the polynomial.
Step 1. Factor our a common factor if possible.
Every term is divisible by 2, so factor out a 2.
4x^2 - 18x - 36 =
= 2(2x^2 - 9x - 18)
Step 2. We need to factor the quadratic trinomial.
Now we have a quadratic trinomial, in which the x^2 term is not plain x^2, but it has a coefficient of 2.
Our polynomial is of the form ax^2 + bx + c, with "a" not equal to 1.
We have 2x^2 - 9x - 18, so we have a = 2, b = -9, c = -18.
We can try guessing, but instead, I will use the "ac" method.
Step A. Multiply coefficients ac:
ac = 2(-18) = -36
Step B. Now we need two numbers that add to b and multiply to ac.
We need two numbers that add to -9 and multiply to -36.
The numbers are -12 and 3 since (-12)(3) = -36, and -12 + 3 = -9.
We now break up the middle term, -9x, using these two numbers.
= 2(2x^2 - 12x + 3x - 18)
Now we factor by grouping. Factor a common factor out of the first two terms, and factor a common factor out of the last two terms.
= 2[2x(x - 6) + 3(x - 6)]
x - 6 is a common factor inside the brackets, so we factor it out inside the brackets.
= 2[(x - 6)(2x + 3)]
= 2(x - 6)(2x + 3)
2x + 8y = 20
y = 3
Can someone tell me the answer to this pls I beg you
Answer:
x=-2
Step-by-step explanation:
y=3 so 8y=24 sooooooo 2x+24=20 if you subtract 24 from both sides you get 2x=-4 divide by 2 on both side and you get x=-2
Answer:
2x+8y=20
Substitute Y
2x+8(3)=20
Multiply 8 * 3
2x+ 24= 20
substract 24 from 20 do it to the other side as well were basically doing inverse operation in order to keep the varieble by itself
2x=-4
Then do inverse operation of multiplication which is division
2x= -4
---- ----
2 2
2x will cross out and x will be left, -4/ 2 equals -2
so x= -2
The answer will be (-2, 3) or if you're just solving for x its going to be -2

well, let's take a look at the tickmarks on the triangle, the tickmarks mean that AC = CB, both AC and CB stemming out of vertex C, and both twin sides will make twin angles at the "base" or namely ∡A = ∡B, that means that 34 = x - 5, let's also recall that the sum of all interior angles in a triangle is 180°, so
\(34=x-5\implies \boxed{39=x} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\measuredangle A}{34}~~ + ~~\stackrel{\measuredangle B}{34}~~ + ~~\stackrel{\measuredangle C}{4y}~~ = ~~180\implies 68+4y=180 \\\\\\ 4y=112\implies y=\cfrac{112}{4}\implies \boxed{y=28}\)
Answer:
y = 28
Step-by-step explanation:
The dashes on line segments AC and BC indicate that the line segments are equal in length.
Therefore, as the triangle has two sides of equal length, it is an isosceles triangle.
The base angles of an isosceles triangle are equal, therefore ∠A = ∠B.
Interior angles of a triangle sum to 180°.
Therefore:
⇒ ∠A + ∠B + ∠C = 180°
⇒ 34° + 34° + 4y° = 180°
⇒ 68° + 4y° = 180°
⇒ 4y° = 112°
⇒ y = 112° ÷ 4°
⇒ y = 28

if the probability that a portfolio outperforms its benchmark in any quarter is 0.75, the probability that the portfolio outperforms its benchmark in three or fewer quarters over the course of a year is closest to: 0.26 0.42 0.68
The closest solution to this total among the available possibilities is 0.68, indicating that the portfolio is likely to surpass its benchmark in three or fewer quarters over the course of a year.
What is probability?The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms.
Here,
The probability that the portfolio outperforms its benchmark in three or fewer quarters over the course of a year is the sum of the probabilities of outperforming the benchmark in exactly 0 quarters, 1 quarter, 2 quarters, and 3 quarters.
Since the probability of outperforming the benchmark in any quarter is 0.75, the probability of not outperforming the benchmark in a quarter is 1 - 0.75 = 0.25.
The probability of not outperforming the benchmark in exactly 0 quarters is 0.25⁰ = 1
The probability of not outperforming the benchmark in exactly 1 quarter is 0.25¹= 0.25
The probability of not outperforming the benchmark in exactly 2 quarters is 0.25² = 0.0625
The probability of not outperforming the benchmark in exactly 3 quarters is 0.25³ = 0.015625
So, the probability of outperforming the benchmark in exactly 0 quarters, 1 quarter, 2 quarters, and 3 quarters is 1 - 0.25⁰, 1 - 0.25¹, 1 - 0.25², and 1 - 0.25³, respectively.
The sum of these probabilities is the probability of outperforming the benchmark in three or fewer quarters over the course of a year:
P(outperform in three or fewer quarters) = 1 - 0.25⁰ + 1 - 0.25¹ + 1 - 0.25² + 1 - 0.25³
This expression can be calculated to get an exact answer, but to get the closest answer to the options given, we can round off the intermediate results to 2 decimal places:
P(outperform in three or fewer quarters) = 1 + 0.75 + 0.94 + 0.98
The closest answer to this sum among the options given is 0.68, so the probability that the portfolio outperforms its benchmark in three or fewer quarters over the course of a year is closest to 0.68.

The gas tank of bus A was 2/3 full of gas. A trip used 2/3 of that gas in the tank. What fraction of gas was used up? The gas tank of bus B was 2/6 full of gas. A trip used 3/4 of that gas in the tank. What fraction of gas was used up? Who used up more gas and by how much more?
Answer:For Bus A:
- The fraction of gas used for the trip is: (2/3) x (2/3) = 4/9
- This means that 4/9 of the gas in the tank was used up.
For Bus B:
- The fraction of gas used for the trip is: (2/6) x (3/4) = 1/4
- This means that 1/4 of the gas in the tank was used up.
Therefore, Bus A used up more gas than Bus B by (4/9 - 1/4) = 1/36.

An equilateral triangle shares a single side with a kite to form a new

Give your answer in degrees (°).
Answer:
<P = 41
Step-by-step explanation:
we can consider this first figure as a quadrilateral and the trianlgle attached to be is equilateral triangle (as it is already shown in the figure that sides are equal)
we know that each angle of equalateral triangle is 60°
we can see that angle 79° is attached to it and even other angle is also attached
let the other angle be x
we can notice that x and the angle of equi triangle make a linear pair
so 180 - 60
= 120°
the opposite angle to the angle x will be also equal as angles on the same side of qual sides will be equal
now we know that total angle sum of quadrilateral is 360°
so
79 + 120 + 120 + <P = 360
319 + <P = 360
<P = 360 - 319
<P = 41
