Write an expression that represents the perimeter of the triangle?
Answer:
(3m - 2) + (5m - 2) + (2m + 7)
Step-by-step explanation:
When you add all the sides together, you get the perimeter.
The expression of the perimeter of the triangle is 10m + 3.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
The three sides of the triangle are:
2m + 7
3m - 2
5m - 2
Now,
The perimeter of the triangle.
= Sum of all the sides
= 2m + 7 + 3m - 2 + 5m - 2
= 10m + 7 - 4
= 10m + 3
Thus,
The perimeter of the triangle is 10m + 3.

in triangle pqr pq=39 in pr=17in, the height pn is 15in. find qr
The value of QR is 3√290.
Given, In triangle PQR
PQ = 39 in PR = 17 in Height PN = 15 in
We need to find QR.
In the right-angled triangle PNR, using Pythagoras theorem,
PN² + PR² = NR²15² + 17²
= NR²NR² = 15² + 17²NR
= √(15² + 17²)NR = √(225 + 289)NR
= √514
Now, in the right-angled triangle PQN,
using Pythagoras theorem,
QR² = PN² + PQ²QR² = 15² + 39²QR²
= 225 + 1521QR² = 1746QR
= √1746QR = 3√290

what is a equation of the line that passes through the point (-4,-6) and is parallel to the line 3x-y=6
Answer:
[tex]y=3x+6[/tex]
Step-by-step explanation:
When solving these types of problems you need to know how to write a line that is parallel to another line. Parallel lines have the same SLOPE but different y-intercepts. But in order to do this, we need to convert this equation to slope-intercept form: y=mx+b.
First, we want to get -y by itself therefore we want to subtract 3x on both sides to get [tex]-y=-3x+6[/tex]. We then want to isolate y by dividing by -1 on each side to get the new equation [tex]y=3x-6[/tex]. We can then use this equation to make a line that is parallel.
Utilizing the slope from the original equation (3) and using the same format for slope-intercept, we get [tex]y=3x+b[/tex]. Our line goes through a certain point therefore our x and y values are given so that our equation looks like [tex]-6=3(-4)+b[/tex]. We now simplify to get [tex]-6=-12+b[/tex] and add 12 on both sides to get b by itself [tex]b=6[/tex].
Lastly, we have all our values and now just need the equation for the line which leaves us with [tex]y=3x+6[/tex].

If the radius of a circle is 9 meters, What is the diameter?
Answer: 18 meters
Step-by-step explanation: The radius is always equal to half the diameter.
So the diameter will be twice the radius so we double the radius.
If we double 9, we get 18.
So the diameter of the circle is 18 meters.
Which of the following actions will always increase voltage?
A: Decreasing resistance and increasing current
B: Decreasing resistance and keeping current constant
C: Increasing resistance and keeping current constant
D: Increasing resistance and decreasing current
Answer:
The decreasing resistance and keeping current constant leads decreasing in voltage option (C) is correct.
What is voltage?
Voltage is the force applied by the power source to charged electrons in a conducting loop, allowing them to perform tasks such as igniting light.
As we know according to the ohm's law:
V = IR
Where 'V' is the volatge,
'I' is the current.
'R' is the resistance.
If we assume 'I' is constant
Then V∝R
As the resistance increases the voltage increases and vice versa.
Thus, the decreasing resistance and keeping current constant leads decreasing in voltage option (C) is correct. HOPE THIS HELPS!

Lucky Lumen light bulbs have an expected life that is exponentially distributed with a mean of 20,000 hours. Determine the probability that one of these light bulbs will last between 5500 and 27500 hours.
Integrating the above expression within the given limits will give us the desired probability. However, the calculation involves numerical integration and may require the use of specialized software or calculators.
To determine the probability that a Lucky Lumen light bulb will last between 5500 and 27500 hours, we can use the exponential distribution formula.
The exponential distribution is defined by the probability density function (PDF):
f(x) = (1/μ) * e^(-x/μ)
Where:
μ is the mean of the distribution
In this case, the mean (μ) of the distribution is given as 20,000 hours.
To find the probability that a light bulb will last between 5500 and 27500 hours, we need to calculate the integral of the PDF within that range.
P(5500 < X < 27500) = ∫[5500, 27500] f(x) dx
P(5500 < X < 27500) = ∫[5500, 27500] (1/20000) * e^(-x/20000) dx
Integrating the above expression within the given limits will give us the desired probability. However, the calculation involves numerical integration and may require the use of specialized software or calculators.

Jimmy brings $24 to the county fair for rides. Roller coaster rides cost $2, and the spinning cup rides cost $3. But Jimmy knows that he gets queasy if he takes more than 6 roller coaster rides or more than 8 spinning cup rides. Let r represent the number of roller coaster rides and let s represent the number of spinning cup rides. In addition to r≥0;s≥0, which is a set of of inequalities that Jimmy can use to guide his choice of rides?
Answer:
2r + 3s ≤ 24
r ≤ 6
s ≤ 8
Step-by-step explanation:
Given the following :
Total amount with Jimmy = $24
Cost of Rollercoaster ride (r) = $2
Cost of spinning cup ride (s) = $3
Queasy if r is greater than 6
Queasy if s is greater than 8
Cost of ride :
(Number of r * cost of r) + (number of s * cost of s) ≤ total amount
Hence,
2r + 3s ≤ 24
To avoid getting queasy :
r ≤ 6
s ≤ 8
2r + 3s ≤ 24
r ≤ 6
s ≤ 8

Amanda reads 300 pages in 10 hours. If each page has 200 words on it, how many words did Amanda read per minute?
Answer:
so that means you would divide 300 by 10 and that means she reads 30 pages in 1 hour so if you do 30 divided by 60 or 1 hour you get 0.5 pages so she reads 100 words in 1 minutes
Step-by-step explanation:
Answer:
100
Step-by-step explanation:
So if there is 200 word per page it will be 200×300, which is 60,000. We are trying to find words per minute, so we do; 10×60 (1 hour=60minutes) which is 600. so to find the words per minute we do:

prove that the sum of the squares of any two consecutive odd integers is even.
any multiple of 2 is even, we can conclude that the sum of the squares of any two consecutive odd integers is even.
Let's say that the two consecutive odd integers are x and x + 2.
So, we can represent the sum of their squares as:x^2 + (x + 2)^2Expanding this out, we get:x^2 + (x^2 + 4x + 4)
Combining like terms, we can simplify this to:2x^2 + 4x + 4Factoring out a 2, we get:2(x^2 + 2x + 2)
So, the sum of the squares of any two consecutive odd integers is 2 times an integer (x^2 + 2x + 2).
Since any multiple of 2 is even, we can conclude that the sum of the squares of any two consecutive odd integers is even.

if a and b are directly proportional and b and c are directly proprtional, then how are a and c related
a and c are directly proportional to each other when a and b are directly proportional and b and c are directly proportional.
If a and b are directly proportional and b and c are directly proportional, it means that their ratios are equal. Direct proportionality implies that as one variable increases, the other also increases in proportion and as one variable decreases, the other also decreases in proportion.
Mathematically, this can be written as
a = kb and b = mc, where k and m are constants of proportionality.
Multiplying these two equations gives: a = kbm
Substituting the value of b from the second equation in the first equation, we get: a = kmc
Therefore, a and c are also directly proportional to each other with a constant of proportionality km.
Thus, if a increases by a certain factor, c will also increase by the same factor.
If a and b are directly proportional and b and c are directly proportional, then it can be concluded that a and c are directly proportional as well.
