The algebraic expression for The quotient of 86 and x
Answer: 86 ÷ x or 86 / x
Step-by-step explanation:
A quotient is a number that results when one number is divided by another.
Therefore, in order to get the quotient, numbers or terms should process division which the final answer would be quotient.
In the process, [÷ ] or [/] the division signs shall be applied.
The quotient of 86 and x represents 86 divided by x, which the final result would be [tex]\boxed {86/x}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
I believe the answer you are looking for is simply just 86÷x or 86/x.

The hypothesis value is used to verify or refute a claim.
The truth value of the hypothesis countered by Emma is trueThe conclusion is falseNote that:
If a conclusion is false, then there can be a counter to refute the conclusion; The hypothesis of this conclusion is trueHowever, if a conclusion is true, then there can't be any counter.Because Emma found a counter, this means that the conclusion is false (as stated in 1, above)

Answer:
[tex]D)\ 25\%[/tex]
Step-by-step explanation:
The following equation can be used to relate the speed time and distance of an object in motion,
[tex](Speed)*(Time)=(Distance)[/tex]
One can also rewrite this equation in terms of time:
[tex](Speed)=\frac{(Distance)}{(Time)}[/tex]
Let this equation represent the relation between Mr.Wang's initial speed and travel time. However, in this problem, Mr.Wang faced a decrease in his speed, more specifically, a (20%) decrease. Subtract (0.2) from (1) to find Mr.Wang's speed in relation to his original speed. Let (x) represent the increase in time that Mr. Wang had to incur in order to reach his destination. Model this situation,
[tex](Speed)*(Time)=(Distance)[/tex]
[tex]0.8(Speed)*x(Time)=(Distance)[/tex]
Now use inverse operations to solve for the coefficient (x):
[tex]0.8(Speed)*x(Time)=(Distance)[/tex]
[tex]x(Time)=\frac{(Distance)}{0.8(Speed)}[/tex]
Using the relation state above: ([tex](Speed)=\frac{(Distance)}{(Time)}[/tex]) one can state the following:
[tex]x(Time)=\frac{(Distance)}{0.8(Speed)}[/tex]
[tex]x(Time)=\frac{1}{0.8}(Time)[/tex]
Thus, (Time) can be omitted from this equation, as it appear on both sides as a factor, hence one can then solve for (x):
[tex]x(Time)=\frac{1}{0.8}(Time)[/tex]
[tex]x=\frac{1}{0.8}[/tex]
Divide (1) by (0.8):
[tex]x=\frac{1}{0.8}\\x=0.25[/tex]
Multiply the decimal by (100) to put it into the percent form:
[tex]x=0.25\\x=25\%[/tex]

Refer to the figure at the right to answer each question. 5. Are points H, J, K, and L coplanar? 6. Name three lines that intersect at X. 7. What points do plane WXYZ and HW have in common? 8. Are points W, X, and Y collinear? 9. List the possibilities for naming a line contained in plane WXKH
Problem 5
Answer: Yes the points are coplanar
------------------------
Explanation:
Note how all four points are in the same plane, aka face, along the top of the 3D block. The term "coplanar" simply means "all in the same plane", so that's why the points are coplanar.
In contrast, the set of points {H,J,K,Z} are not all coplanar because H,J,K are in the top plane, while Z is not.
===========================================================
Problem 6
Answer: line segments WX, XY, and XK
------------------------
Explanation:
All three lines mentioned above involve the letter X in some fashion. The order doesn't matter. Also, those lines intersect at the common point X.
===========================================================
Problem 7
Answer: point W
------------------------
Explanation:
The plane WXYZ is the bottom face, in which we can think of as the floor of the building. The segment HW is from the floor and goes up vertically. We can consider this to be like a pole beam of the structure. The plane and segment both have point W in common. Note that the letter "W" is found in the sequences WXYZ and HW, and it's the only common letter.
===========================================================
Problem 8
Answer: The points are not collinear
------------------------
Explanation:
To be collinear, the points must all be on the same straight line. We see that isn't the case with points W, X and Y.

a total of $10,000 is invested in two funds, Fund A and Fund B. Fund A pays 5% annual interest and Fund B pays 7% annual interest. The combined annual interest is $630. How much of the $10,000 is invested in Fund A?
The amount of the 10000 invested in each Fund A is $5,300
First step is to calculate the amount invested in Fund B
Let x represent the amount invested at 7%
.07x+.05(10000-x)=630
Open the bracket
.07x+500-.05x=630
Collect like terms
.02x=630-500
.02x=130
x=130/.02
x=$6,500
Second step
Now let calculate How much of the $10,000 is invested in Fund A
Fund A amount invested=10000-6500
Fund A amount invested=$3500
Inconclusion The amount o of the 10000 invested in each Fund A is $5,300

in thailand the population of town is 48700 men and 41600 women what percentage of the total percentage are men
Answer:
53.931339977852% (you can round)
Step-by-step explanation:
You add up 48,700 and 41,600 and you would get 90,300 as the overall population. Then you would put it in fraction form if you want to convert it into a percentage. The fraction form would be 48,700/90,300. You could simplify it to 487/903. Then you do 487 x . You would cross multiply and get
___ = ___
903 100
903x = 48700. Then you would divide each side by 903 and get x = 53.931339977852% (you can round)
Answer:
Approximately 53.9%
To be exact, answer is 48700/903
Step-by-step explanation:
Percentage of men = Men ➗ Total population
48700 + 41600 = 90300
48700/90300 is approximately 0.539
0.539 * 100 = 53.9

Jon has to pay $7.00 admission for the skating rink in $1.50 per hour to rent rollerblades. How many hours can he skate for $19?
Answer: 8 hours
Step-by-step explanation:
Given information
Admission fee = $7.00
Hour rent fee = $1.50
Number of hours = h
Total fee = $19
Set equation according to the given information
Total fee = admission fee + (hours) × (hour rend fee)
Substitute values into the equation
19 = 7 + 1.5h
Subtract 7 on both sides
19 - 7 = 7 + 1.5h - 7
12 = 1.5h
Divide 1.5 on both sides
12 / 1.5 = 1.5h / 1.5
[tex]\boxed{h=8}[/tex]
