The perimeter of a triangle is 78 if QA=10. SQ=28, BR=15 and A is the midpoint of QR, B is the midpoint of RS, and C is the midpoint of SQ in triangle QRS.
What is meant by triangle?In Euclidean geometry, any three non-collinear points define a unique triangle and, at the same time, a unique plane. In other words, the triangle is contained in just one plane, and every triangle is contained in at least one plane. There is just one plane and all triangles are enclosed in it if the entire geometry is merely the Euclidean plane; however, this is no longer true in higher-dimensional Euclidean spaces. Unless otherwise specified, this article is about triangles in Euclidean geometry, specifically the Euclidean plane.
Given,
In triangle QRS, A is the midpoint of QR, B is the midpoint of RS, and C is the midpoint of SQ
Also given that,
QA=10
BR=15
SQ=28
QA=RA=10
BR=SB=15
Therefore, perimeter of the triangle=RQ+QS+RS
=(RA+QA)+(QS)+(RB+BS)
=(10+10)+(28)+(15+15)
=20+28+30
=78
Hence, the perimeter of a triangle=78

Answer:
B
Step-by-step explanation:
The distance between the lines stays constant, and they never intersect. In other words, you can translate (move) either line by that constant distance, in some direction, to get the other line. It's just like how when you change the y-intercept but keep the slope the same, you get parallel lines.

Last week Len spent $18 to bowl 4 games. This week he spent $27 to bowl 6 games Len owns his bowling ball and shoes, so he only has to pay for each game that he bowls. If each of these bowling games costs the same amount of money, what is the constant of proportionality between the money spent and the number of games played?
The constant of proportionality in both situations is 4.5
Constant of ProportionalityThe constant of proportionality is the ratio that relates two given values in what is known as a proportional relationship. Other names for the constant of proportionality include the constant ratio, constant rate, unit rate, constant of variation, or even the rate of change.
The equation of constant of proportionality is given as

Based on the giving information, what is the measure of the missing length, w?
The measure of the missing length of the triangle is 16 units.
According to the question,
We have the following information:
We have a figure of right-angled triangle where two sides are given.
In order to find the third side of this triangle, we will use the Pythagoras theorem.
So, we have the following expression:
[tex]AC^{2} = AB^{2} + BC^{2}[/tex]
[tex](20)^{2} = AB^{2} + (12)^{2}[/tex]
400 = [tex]AB^{2}[/tex] + 144
Subtracting 144 from both sides of the equation:
[tex]AB^{2}[/tex] = 400-144
[tex]AB^{2}[/tex] = 256
We know that the square root of 256 is 16 or in other words, the square of 16 is 256.
AB = 16 units
Hence, the measure of the missing length of the triangle is 16 units.

The probability that Jordan will win in three or fewer matches if they play 5 matches using binomial probability distribution is; 0.95636
How to solve Binomial probability distribution problems?The binomial probability is defined as the probability of exactly x successes on n repeated trials, with p probability.
The general formula for binomial probability distribution is;
P(X = x) = nCx * p^(x) * (1 - p)^(n - x)
where;
Px = the probability of exactly x events occurring
x = the number of expected successful outcomes
n = the number of trials you perform
nCx = the number of different combinations for x items you test in n trials
We are given probability that Jordan wins the match as 1/3. Thus;
p = 1/3 = 0.333
Thus, probability that Jordan will win in three or fewer matches if they play 5 matches is;
P(X ≤ 3) = P(0) + P(1) + P(2) + P(3)

P(X ≤ 3) = 0.95636

TYPING Nebi has already typed 250 words. He then starts a timer and finds that he types 150 words in 3 minutes. If Nebi types at a constant rate, write a linear equation to represent the number of words w Nebi types m minutes after starting the timer.
The linear equation that represents the number of words Nebi types per minutes after the timer is started is: w = 50m + 250.
How to Write a Linear Equation?Linear equation can be written in the slope-intercept form as y = kx + b. To write this, find the values of the slope = m, and the y-intercept of starting value = b.
From the equation given, find the unit rate/slope, which is the number of words typed in one minute.
Thus, we have:
Slope/unit rate (m) = 150/3
m = 50 words per minute.
The y-intercept (b) is 250, because it is the initial/starting value.
Let w represent the total number of words, and m represents the minutes after the starting time.
To write the linear equation, substitute k = 50 and b = 250 into w = km + b:

mL of the 65% solution
As per the concept of unitary method, there are 180.8 ml of the 65% mixture will you need to add to obtain the desired solution
Unitary method:
Basically, the way of finding out the solution of a problem by initially finding out the value of a single unit, and then finding out the essential value by multiplying the single unit value.
Given,
You need a 35% alcohol solution. On hand, you have a 300 mL of a 20% alcohol mixture. You also have 65% alcohol mixture.
Here we need to find how much of the 65% mixture will you need to add to obtain the desired solution.
Let us consider x be the amount of the 65% alcohol needed (in milliliters.
Here the amount of the resulting 65% alcohol solution will be is (x+15) milliliters.
So, the amount of the "pure" alcohol in 300 mL of the 20% alcohol solution is written as,
=> 0.20 x 300 mL.
And the amount of the "pure" alcohol in x mL of the 65% alcohol solution is written as,
=> 0.65 * x mL.
Therefore, the total amount of the "pure" alcohol in ingredients is the sum and it can be calculated as,
=> 0.20*300 + 0.65*x mL.
So, it should be equal to the amount of the "pure" alcohol in the mixture, which is written as,
=> 0.35 * (x+15) ml.
Therefore, your "pure alcohol" equation is
=> 0.65* x + 0.20 * 300 = 0.35*(x+15).
When we simplify this one then we get the value of x as,
=> 0.65* x + 0.20 * 300 = 0.35*(x+15).
=> 0.65x + 60 = 0.35x + 5.25
=> 0.3x + 54.25
=> x = 180.8
