Which of the follow triangles is similar to APOR?
Answer:
D
Step-by-step explanation:
For each triangle, you are given two sides and the included angle (the one between those 2 sides). That's side-angle-side, so it is S-A-S.
The SAS Rule for Similar Triangles says that for 2 triangles X and Y, if you have the SAS of one and the SAS of the other, then X and Y are similar (same shape and proportions) if
(a) the angle in X is congruent (same) as the angle in Y
(b) the ratio between the two given sides in X is the same as the ratio between the two given sides in Y
For this particular problem, the ratio PR/PQ = 18/21 = 6/7 if you simplify by dividing both top and bottom by 3.
So we are looking for another triangle where we have the same ratio. (Put the smaller number on top, in the fraction.)
Answer A: 12/15 simplifies to 4/5, wrong answer
Answer B: 9/12 simplifies to 3/4, wrong answer
Answer C: 6/10 simplifies to 3/5, wrong answer
Answer D: 15/17.5 looks harder, because there is a decimal in it. But we know 17.5 is just 17 and a half, so I would first multiply top and bottom by 2
We get 30/35. That looks a lot better. Now it is easier to see we can divide both top and bottom by 5.
We get 6/7! That is the correct answer, so D is the triangle similar to PQR.

what is the point-slope form of the equation for the line with a slope of -2 that passes through the point (4,-6)
Answer:
[tex]y + 6 = -2 (x-4)[/tex]
Step-by-step explanation:
Point-slope formula is represented by the equation [tex]y-y_1 = m (x-x_1)[/tex]. When knowing a point a line crosses through and its slope, you can write an equation in this form. Substitute the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.
The [tex]m[/tex] represents the slope of the line. Since we know the slope is -2, substitute -2 for [tex]m[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of the point the line passes through. Since the line passes through (4, -6), substitute 4 for [tex]x_1[/tex] and -6 for [tex]y_1[/tex]. This gives the following answer and equation:
[tex]y-(-6) = -2 (x - (4))\\y + 6 = -2 (x-4)[/tex]
Answer:
y=-2x+2
Step-by-step explanation:
y-y1=m(x-x1)
y-(-6)=-2(x-4)
y+6=-2(x-4)
y=-2x+8-6
y=-2x+2
At Katy Perry concert, the ratio of the number of boys tot the number of girls on 4:5. If there are 250 more girls than boys how many boys are at the concert?
Answer:
1000 boys
Step-by-step explanation:
The ratio of the number of boys to girls is 4:5.
Every time you multiply 4 and 5 by the same whole number, you get a possible number of boys and girls in the same ratio.
There may be
4 boys and 5 girls, or
8 boys and 10 girls (multiplying 4 and 5 by 2), or
12 boys and 15 girls (multiplying 4 and 5 by 3), or
400 boys and 500 girls (multiplying 4 and 5 by 100),
but all these numbers are too low for there to be a difference of 250 between the numbers of boys and girls. Since we don't know the numbers of boys and girls, but know the ratio is 4:5, then we know that the ratio is also 4x:5x, by multiplying both numbers of boys and girls in the ratio by x.
There are 250 more girls than boys, so
5x - 4x = 250
x = 250
The number of boys is 4x.
4(250) = 1000
Answer: 1000 boys

it's negative 8 so its 8 below
A plane with the tailwind is 500 km/h. While going against the wind it is 410 km/h. What is the speed of the plane without wind?
Answer:
45
Step-by-step explanation:
Let the plane speed be x
Let the wind speed be y
x +y= 500.....equation 1
x -y= 410........equation 2
x + y= 500
-
x- y= 410
2x= 90
x= 90/2
x= 45
From equation 1, substitute 45 for x
x + y= 500
45 + y= 500
y = 500-45
x = 455
Hence the speed of the plane is 45
Laura buys an unfair coin online. The coin is supposed to land heads up 75% of the time. If this is true, what is the
probability that in 20 flips, the first 15 land heads up and the last 5 land tails up?
Answer:
C . (0.75) 15 x (0.25) 5
Step-by-step explanation:
Took the assignment in edge, it’s right
Its based off of the rule P(A and B) = P(A) x P(B) from multiplication rule for independent events.
The probability that in 20 flips, the first 15 land heads up and the last 5 land tails up is 0.000390625.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
If the coin is supposed to land heads up 75% of the time, then the probability of getting heads on a single flip is 0.75 and the probability of getting tails is 0.25.
To find the probability that in 20 flips, the first 15 land heads up and the last 5 land tails up, you can use the formula for the probability of independent events:
P(A and B) = P(A) × P(B)
where A and B are independent events, and P(A) and P(B) are the probabilities of events A and B occurring, respectively.
In this case, the probability of the first 15 flips landing heads up is P(A) = 0.75¹⁵, and the probability of the last 5 flips landing tails up is P(B) = 0.25⁵.
Therefore, the probability that in 20 flips, the first 15 land heads up and the last 5 land tails up is:
P(A and B) = P(A) × P(B) = (0.75¹⁵) × (0.25⁵) = 0.000390625

which of the following statements must be true if GHI-JKL ?
1. The corresponding sides of the two triangles must be proportional.
2.The two triangles must have exactly one acute angle.
3.At least one of the sides of the two triangles must be parallel.
4.The sides of the triangles must have equal lengths.
5. The two triangles must be scalene.
6. None of the above.
Answer:
1. The corresponding sides of the two triangles must be proportional.
Step-by-step explanation:
Option 1, is the only statement that makes GHI = JKL true. If the triangles are congruent, it means that the sides have to be proportional.
The triangles GHI and JKL are similar, Δ GHI ≈ Δ JKL only if their two corresponding sides are proportional and one angle is also equal, so option 1 is correct.
What is the triangle?Three straight lines coming together create a triangle. There are three sides and three corners on every triangle (angles). A triangle's vertex is the intersection of two of its sides. Any one of a triangle's three sides can serve as its base, however typically the bottom side is used.
Given:
The triangles GHI and JKL are similar, Δ GHI ≈ Δ JKL,
The condition for the similarity of the triangle are shown below,
Two triangles are said to be comparable if the ratio of one triangle's two sides to the two sides of another triangle is the same, and the angles that the two sides of both triangles inscribe are equal.
Thus, the sides have to be proportional.

what is difference between point and dot
Answer:
A dot is a physical object, not a mathematical object. A dot has a size and is roughly circular, but the size is not defined. It’s a fuzzy concept; how big does it have to be before it’s no longer a dot but a blot? An how irregular can a dot be?
A point is a mathematical object in geometry. It has a position but no size. It has no definition because none of the basic objects of mathematics has a definition. The axioms of geometry give relationships between and properties of undefined terms such as point, line and plane.
