The length of TR is 17 units. What are the lengths of SV and QT?
SV=___ units
QT=___ units
Answers
Answer:
SV= 41 units
QT: 21 units
Step-by-step explanation:
hope it helps:)
Given TR = 17 units, TRS = 9x - 4, VRS = 3x + 2, and QRV = 4x + 1, with x ≈ 1.583. SV ≈ 6.749 units and QT ≈ 7.332 units.
To find the lengths of SV and QT, we'll first set up equations based on the given relationships between the lengths of the segments.
Given:
- Length of TR = 17 units
- Length of TRS = 9x - 4
- Length of VRS = 3x + 2
- Length of QRV = 4x + 1
We need to find the lengths of SV and QT.
1. Length of TRS + Length of VRS = Length of TR (by the segment addition postulate)
9x - 4 + 3x + 2 = 17
12x - 2 = 17
12x = 17 + 2
12x = 19
x = 19 / 12
x ≈ 1.583
Now that we have found the value of x, we can find the lengths of SV and QT.
2. Length of SV = Length of VRS = 3x + 2
Length of SV = 3(1.583) + 2
≈ 4.749 + 2
≈ 6.749 units
3. Length of QT = Length of QRV = 4x + 1
Length of QT = 4(1.583) + 1
≈ 6.332 + 1
≈ 7.332 units
So, the lengths are:
- SV ≈ 6.749 units
- QT ≈ 7.332 units

What is the inverse of the function f(x) = 2x – 10? h(x) = 2x – 5 h(x) = 2x + 5 h(x) = x – 5 h(x) = x + 5
Answers
y = 2x -10
Switch y and x,
x = 2y -10
solve for y,
x + 10 = 2y
x/2 + 10/2 = y
x/2 + 5 = y
y = x/2 + 5 or h(x) = x/2 + 5
Hence, the inverse of the function f(x) = 2x-10 is h(x) = x/2 + 5
The inverse of a function is gotten by swapping the x and y coordinates.
The inverse of function f(x) is[tex]h(x) = \frac x2 + 5[/tex]
Given
[tex]f(x) = 2x - 10[/tex]
Rewrite as:
[tex]y = 2x - 10[/tex]
Swap x and y
[tex]x = 2y - 10[/tex]
Solve for y
[tex]2y = x + 10[/tex]
Divide by 2
[tex]y = \frac x2 + 5[/tex]
So, we have:

The measured weights of 1,000 men in a certain village follow a normal distribution with a mean of 150 pounds and a standard deviation of 15 pounds. Which sentence most closely summarizes the data?
About 160 people weigh more than 165 pounds.
About 320 people weigh more than 165 pounds.
About 320 people weigh less than 165 pounds.
About 640 people weigh less than 165 pounds.
Answers
The correct summary of the data is that about 160 people weigh more than 165 pounds, based on the empirical rule for a normal distribution.
Explanation:To summarize the data of the measured weights of 1,000 men in a certain village, which follows a normal distribution with a mean of 150 pounds and a standard deviation of 15 pounds, we can use the empirical rule (68-95-99.7). According to this rule, approximately 68% of data values fall within one standard deviation of the mean, 95% fall within two standard deviations, and 99.7% fall within three standard deviations.
In this context, since 165 pounds is one standard deviation above the mean (150 + 15 = 165), it means approximately 16% of men (100% - 84%) will weigh more than 165 pounds, which translates to about 160 people (0.16 * 1000).
Therefore, the correct summarization is: About 160 people weigh more than 165 pounds.

Which of these statements about statistical models is true? I. Statistical models help better understand real-world systems. II. Statistical models represent the real world. III. Statistical models help predict future behavior.
Answers
Final answer:
Statistical models help understand real-world systems, represent simplified versions of reality, and aid in predicting future behavior. However, they are not perfect and contain uncertainties.
Explanation:
The question at hand is about statistical models and their characteristics. Statistical models do indeed serve several key functions, and among the statements listed, all are true to a certain extent:
Statistical models help better understand real-world systems by simplifying complex phenomena and making them more approachable for analysis.Statistical models represent the real world, but it is important to note that they are simplifications and may not capture all the nuances of real-world behavior.Statistical models help predict future behavior by using historical data and probabilistic methods to make informed guesses about what might happen under similar circumstances.However, it is crucial to remember that while statistical models are powerful tools for interpretation and prediction, they are not perfect representations of reality and come with inherent uncertainties and limitations.
What is the greatest common factor of 34n and 8n^2?
Answers
_________________________________
The greatest common factor (GCF) of 34n and 8n² is: 2n .
__________________________________________
Explanation:
_______________
First, break down EACH term into prime factors:
__________________________________________
Start with the first term given: "34n" :
__________________________________________
34n = 17 * 2 * n
__________________________________________
Now, do so with the second term given: "8n² " :
__________________________________________
8n² = 2 * 2 * 2 * n * n
_______________________________________________
Now, look for factors that exist in EACH of the two terms:
_______________________________________________
In the term: "34n"; there is a "17", and a "2" and a "n" — and that's it!
_______________________________________________
In the term: "8n² " that is a "2" and an "n".
_______________________________________________
So: 2 * n = 2n ; which is our answer:
_______________________________________________
The greatest common factor (GCF) of 34n and 8n² is: 2n .
_________________________________________________________
The greatest common factor of 34n and 8n² is 2n, as both expressions share the variable n and the highest common numerical coefficient is 2.
The greatest common factor (GCF) of two algebraic expressions can be found by identifying the highest powers of common factors in the terms. For the expressions 34n and 8n², both terms have n as a common factor. Since we want the greatest common factor, we take the highest power of n that appears in both terms, which is n (not n² because n is the highest power in the least degree term, 34n). Next, we find the GCF of the numerical coefficients 34 and 8, which is 2. Therefore, the greatest common factor of 34n and 8n² is 2n.

I really need help solving this whole problem.
Answers
No, you do not have enough information to determine the price of both gasoline and oil from the prices that "you" and "your friend" paid at the station. If you look closely, you'll notice that "your friend" bought half the amount of gas and oil that you did and paid half the price-- you won't get a satisfactory answer from just this information.
b.
Yes, with this you can use elimination to solve the systems, as you bought 2 quarts of oil and 10 gallons of gas for $45.50 and the receipt owner bought 2 quarts of oil and 8 gallons of gas for $38.40.
c.
Alright, so here is elimination, that is, eliminating a variable if you add two equations together. (This is a confusing answer so I would suggest you ask someone else for a better one).
So, first we make an equation out of the word problem in the beginning.
I'll treat 1 gallon of gas as "g", and one quart of oil as "o".
45.50 = 10g + 2o
+ 38.40 = 8g + 2o
You'll note that there are 2 "o"s in each equation. So, we'll multiply the bottom equation by -1 so the "o" cancels out and we can get the value of "g".
45.50 = 10g + 2o
+ (38.40 = 8g + 2o) * -1
This becomes:
45.50 = 10g + 2o
+ -38.40 = -8g - 2o
Subtract, and this becomes
7.1 = 2g
/2
g = 3.55
Alright, so now we know the value of a gallon of gas. Let's substitute this back into the original equation to find the price for the oil.
45.50 = 10(3.55) + 2o
45.50 = 35.5 + 2o
-35.5 -35.5
10 = 2o
/2
o = 5
So we know that 1 gallon of gas is $3.55 and one quart of oil is $5.00.

Answers
S is the three digit number.
h - a number of hundreds
t - a number of tens
o - a number of ones
S = 100h + 10t + o
The last two digits add to make ten: t + o = 10
The first and last digits add to make eight: h + o = 8
The first two digits add to make twelve: h + t = 12
t + o = 10 ⇒ o = 10 - t
h + o = 8 ⇒ o = 8 - h
_______
10 - t = 8 - h
h + t = 12 ⇒ h = 12 - t
_______
10 - t = 8 - (12 - t)
10 - t = 8 - 12 + t
10 - t = -4 + t
10 + 4 = t + t
2t = 14
t = 14/2 = 7
______
h = 12 - t = 12 - 7 = 5
______
o = 8 - h = 8 - 5 = 3
S = 100h + 10t + o
h = 5
t = 7
o = 3
S = 100*5 + 10*7 + 3

Hope this helps!
Final answer:
The expression that is equivalent to 4t + 3t is 7t, as you combine the like terms by adding their coefficients.
Explanation:
The student has asked which expression is equivalent to 4t + 3t. This is a problem in basic algebra and involves combining like terms. To find the equivalent expression, we simply add the coefficients (numbers in front of the variable 't') together. Since both terms have the same variable 't', we combine 4 and 3 to get 7. Therefore, the equivalent expression to 4t + 3t is 7t.
