Kado spent 1 2/3 hours painting a fence. Then he spent 4/5 of an hour walking his dog. How much longer did he spend painting than walking? Orleans chose C as the correct answer.How did she get that answer?
Answers
Answer: B, 13/15
Step-by-step explanation: If you multiply both to 15, you will get 1 10/15 and 12/15 if you then subtract the two of them you will be left with
13/15.
Orleans might have got the answer from subtracting wrong or adding them together.
Hope this helps! :)
Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.
To find out how much longer Kado spent painting than walking his dog, we need to calculate the difference between the time he spent painting and the time he spent walking his dog.
Kado spent 1 2/3 hours painting the fence.
He spent 4/5 of an hour walking his dog.
To make the calculation easier, let's convert 1 2/3 hours into an improper fraction:
1 2/3 = (3*1 + 2)/3 = 5/3 hours
Now, the time difference is:
Time spent painting - Time spent walking
= (5/3) - (4/5)
To subtract fractions, we need to find a common denominator, which in this case is 15 (the least common multiple of 3 and 5):
= (5/3)(5/5) - (4/5)(3/3)
= 25/15 - 12/15
Now, we can subtract the fractions:
= (25 - 12)/15
= 13/15 hours
Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.

The relative frequency of the columns are:
Group 1 Group 2 Group 3
Category 1 4/11 1/4 11/19
Category 2 7/11 3/4 8/19.
What is the frequency?
The number of times a specific value appears in the data is its frequency (f). A variable's distribution is its frequency pattern, or the collection of all conceivable values and the frequencies corresponding to those values. Frequency tables or charts are used to represent frequency distributions.
Given table is
Group 1 Group 2 Group 3
Category 1 4 3 11
Category 2 7 9 8
The frequency of group 1 is (4+7) = 11
The frequency of group 2 is (3+9) = 12
The frequency of group 3 is (11+8) = 19.
The relative frequency is the ratio between the number of times an outcome value appears in the set of all outcomes and the total number of outcomes.
Group 1 Group 2 Group 3
Category 1 4/11 3/12 = 1/4 11/19
Category 2 7/11 9/12 = 3/4 8/19.

Describe the pros and the cons of using the standard form of a line to graph an equation.
Answers
Answer:
The standard form of a line is expressed as Ax + By = C, where A, B, and C are constants and x and y represent the variables. One advantage of using the standard form to graph a line is that it is relatively easy to determine the slope and y-intercept of the line from the constants A and B. This can be particularly useful when trying to analyze the behavior of the line.
Another advantage of using the standard form is that it allows you to easily determine the equation of the line when given a set of points. For example, if you are given the points (2,4) and (3,6), you can use the standard form to find the equation of the line that passes through these points by substituting the coordinates into the form and solving for the constants.
One potential disadvantage of using the standard form is that it can be more difficult to interpret the meaning of the constants A, B, and C in terms of the context of the problem. For example, if the line represents the cost of a product, it may be more intuitive to express the equation in terms of the variables x (the number of units) and y (the cost). In this case, it may be more useful to use the slope-intercept form of the equation, which is expressed as y = mx + b, where m is the slope and b is the y-intercept.

What is the value of x in this triangle? What is the value of each angle?
Answers
Answer:
x=17
Step-by-step explanation:
we know the 25 + 90 = 115 so we need the other one to make it 180 degrees.
180-115= 65
so we need 65 more degrees to get 180
now 3x + 11= 65 first step subtract 11 on both sides
you now get 3x = 54 then 2nd step is divide 3 on both sides
and now you get x=17 so
Answer:
Step-by-step explanation:
The entire value of the triangle is 180 degrees.
If you subtract 25 from 180 you are left with 155
Then Subtract 90 from 155 which will leave you with 65
Go on to subtract 11 from 65 having to be with 54 degrees left
Finally you will dived 54 by 3 and you are left with 18
3 x 18 = 54
54 + 11 = 65
Therefore x will equal to 65 degrees

A. The constant ratio of y/x is 12/5
Step-by-step explanation:
The ratio of y to x is constant which is 12/5. Hence option A is the correct option.
What is a constant?
The term "constant" has several meanings in mathematics. When used as a noun, it can have any of the following two meanings: a constant, clearly defined number or another immutable mathematical object.
Given table is
x y
5/6 2
25/6 10
125/6 50
625/6 250
When x = 5/6 and y = 2:
x/y = (5/6)/2 = 5/12
∴y/x = 5/12
When x = 25/6 and y = 10:
x/y = (25/6)/10 = 25/60 = 5/12
∴y/x = 5/12
When x = 125/6 and y = 50:
x/y = (125/6)/50 = 125/300 = 5/12
∴y/x = 5/12
When x = 625/6 and y = 250:
x/y = (625/6)/250 = 625/1800 = 5/12
∴y/x = 5/12
