Ratio and Proportion can be used to convert weights between different systems of measurement. True False
The answer you are looking for is true
Answer:
The answer is true.
Step-by-step explanation:
Ratio and Proportion can be used to convert weights between different systems of measurement. This is true.
When we are given any problem with different measurements, then we should first convert the problem in such a unit that all units are the same.
We can define ratio as a comparison between two numbers.
Whereas the proportion is a comparison between two ratios.
What is the solution to the equation 2/3x+1=1/6x-7?
A. x=-16
B. x=-4
C. x=4
D. =16
(2/3)x+1=(1/6)x-7
*Isolate the variable by subtracting (1/6)x from both sides*
0.5x+1=-7
*Subtract 1 from both sides*
0.5x=-8
*Divide both sides by 0.5*
A. x=-16
Hope this helps!!
Answer:
A
Step-by-step explanation:
To eliminate the fractions in the equation, multiply all terms by the lowest common multiple of 3 and 6, that is 6
4x + 6 = x - 42 ( subtract x from both sides )
3x + 6 = - 42 ( subtract 6 from both sides )
3x = - 48 ( divide both sides by 3 )
x = - 16

Answer:
5
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 4, 8 ] and from the graph
f(b) = f(8) = 10
f(a) = f(4) = - 10, hence
average rate of change = [tex]\frac{10-(-10)}{8-4}[/tex] = [tex]\frac{20}{4}[/tex] = 5

a circular native american dwlelling has a diameter of 24 feet. how much are inside the home? use 3.14 for { } (pi)
Answer :
[tex]A = 452.16 \: {ft}^{2}[/tex]
step-by-step explanation:
From the question,
the diameter:
[tex]d = 24 \: ft[/tex]
The radius :
[tex]r = \frac{diameter}{2}= \frac{24}{2}=12 \: ft[/tex]
[tex]\pi = 3.14[/tex]
Area of a circle is given as
[tex]A = \pi {r}^{2} [/tex]
By substitution,
[tex]A = 3.14( {12}^{2} )[/tex]
[tex]\implies \: A = 3.14 \times 144[/tex]
[tex]\implies \: A = 452.16 \: {ft}^{2} [/tex]
Hence the area of the home is
[tex]A = 452.16 \: {ft}^{2}[/tex]
If it takes 4 workers ,4 hours to dig 4 wholes, how long would it take 2 workers to dig 6 holes?
Answer:
2 workers will take 12 hours to dig six holes
Two workers take 12 hours to dig 6 holes.
What is unitary method?The method in which first we find the value of one unit and then the value of the required number of units is known as the Unitary Method.
Let t be the time taken by the two workers to dig a six hole.
According to the given question.
4 workers take 4 hours to dig 4 holes.
So, the number of hours taken by the one workers to dig a one hole is given by
Number of hour taken by a single worker to dig 1 hole = [tex]\frac{4 \times 4}{4}[/tex] = 4hours
Therefore,
The time taken by 2 workers to dig 6 holes is given by
[tex]\frac{4\times 4}{4} = \frac{2\times t }{6} \\\implies 4 \times 6 = 2\times t\\\implies 24= 2\times t\\\implies t = \frac{24}{2} \\\implies t = 12 hours[/tex]
Hence, two workers take 12 hours to dig 6 holes.

Meryl needs to cut down 10.5 trees for every 5 cabins she builds. how many trees will she need to cut down if she builds 7 cabins?
Answer:
14.7 trees
Step-by-step explanation:
First you need to find how many trees she cuts down to build one cabin. So you divide:
10.5/5=2.1
She cuts down 2.1 trees to make one cabin.
Next you multiply:
2.1*7=14.7

A house has increased in value by 29% since it was purchased. If the current value is $516,000, what was the value when it was purchased?
X=value of the house before increase
(100%+29%)X=516,000
(129%)X=516,000
1.29x=516,000 | divided by 1.29 both sides
X=400,000$ was the value when it was purchased
Answer:
The value of house $ 400,000
Step-by-step explanation:
Let x be the price of house when it was purchased,
∵ 29% of x = [tex]\frac{29x}{100}[/tex] = 0.29x
According to the question,
x + 29% of x = 516000
x + 0.29x = 516000
1.29x = 516000
[tex]\implies x=\frac{516000}{1.29}=400000[/tex]
Hence, the value of the house is $ 400,000 when it was purchased.

Which of the following equations best represents the trend line for the scatter plot shown below
- Y= 1/3x+8
- Y=3x+5
- Y= 3x+8
Answer:
y = 3x + 5
Step-by-step explanation:
First start at your y intercept (5) and use the rise to run ratio (rise 3, run 1) and there is a point on every single one.
1/3 wouldn't work because you rise 1 and go right 3 and that does not match any of the points
Using the two points first gives us a slope of 3
(1, 8) (2, 11)
m(slope) = (y2 - y1)/(x2 - x1)
m = (11 - 8)/(2 - 1)
m = 3/1
m = 3
We also know that 8 cannot be the intercept being as it is the point at x = 1. Therefore, we know that y = 3x + 5 must be the only possible answer.
Answer:
The answer is B. y = 3x+5

Can the following question be considered a statistical question and why or why not?
Do students at Bryan Middle School exercise?
Yes, it specifies the population
No, it does not specify the population
Yes, it anticipates enough variability in responses
No, it does not anticipate enough variability in responses
I'm giving 25 points for this since the people who answered last question similar to this were not smart enough to ask the bloody question maker to add the answers for the multiple choice.
Final answer:
The question 'Do students at Bryan Middle School exercise?' is not a statistical question because it is a yes/no question that does not anticipate enough variability in responses. A statistical question would allow gathering of varied data which could be analyzed for patterns and insights.
Explanation:
Whether the question "Do students at Bryan Middle School exercise?" can be considered a statistical question depends on its potential to produce a variety of results that can be analyzed. Statistical questions anticipate variability in responses and usually involve a degree of uncertainty that can be measured and analyzed.
To evaluate the provided question, it does specify a population, which is the students at Bryan Middle School. However, the question, as it stands, is a yes/no question and does not necessarily anticipate enough variability in responses. A richer statistical question would allow us to collect data that varies among individuals and potentially reveals patterns, such as "How many hours per week do students at Bryan Middle School exercise?"
Therefore, the answer is 'No, it does not anticipate enough variability in responses.' It is essential in research methods and methodologies to ask questions that lead to data that can be used for meaningful analysis and inference.

Julianne and Derek made signs for their school spirit week. Julianne made a sign that is 3 1/2 feet long. Derek made a sign that is 5/6 as long as Julianne’s sign. How long is the sign Derek made?
Answer:
2 2/3 is what I got
Step-by-step explanation:
subtract 5/6 from 3 1/2
Final answer:
Derek's sign is 2 feet and 11/12 of a foot long, as we multiply 7/2 (Julianne's sign length in improper fraction) by 5/6 (the length ratio of Derek's sign to Julianne's) to get the answer.
Explanation:
To find the length of the sign Derek made, we need to calculate 5/6 of the length of Julianne's sign. Julianne's sign is 3 1/2 feet long. To facilitate the multiplication, we first convert 3 1/2 feet to an improper fraction, which is 7/2 feet.
Now, we multiply 7/2 (the length of Julianne's sign) by 5/6 (the factor by which Derek's sign is shorter).
(7/2) × (5/6) = 35/12 feet
To simplify 35/12, we divide 35 by 12, which equals 2 with a remainder of 11. Therefore, Derek's sign is 2 feet and 11/12 of a foot, or approximately 2.92 feet long.

what is 550% as a fraction or mixed number
Answer:
11/2 = 5 1/2
Step-by-step explanation:
P(A)=0.22 and P(B)=0.46
Find P(A OR B)
In general, the probability of a disjunction is
[tex]P(A \lor B) = P(A)+P(B)-P(A\cap B)[/tex]
In this case, A and B are mutually exclusive, so [tex]P(A\cap B)=0[/tex]
This simplifies the formula to
[tex]P(A \lor B) = P(A)+P(B) = 0.22+0.46 = 0.68[/tex]
