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

Answer:
w raised to the power of 10
Step-by-step explanation:
When you have a power raised to a power, you multiply the exponents.
You can check by using a real number for the variable
(2²) raised to the power of 5
4 raised to the power of 5 = 4 x 4 x 4 x 4 x 4 = 1024
5x2 = 10
2 raised to the power of 10 = 1024

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.
===========================================================
Problem 9

Which of the following is the equation of the line that has x-intercept -2 and y-intercept -6?
А. y=-3x - 6
B. y=-2x - 6
C. y=-6x-2
D. y = 3x - 2
Answer:
a
Step-by-step explanation:
y=mx+c, where c is the y-intercept. hence,
y=mx-6
at the x-intercept, y=0 and x = -2
0 = m(-2)-6
2m = -6
m = -3
y = -3x-6
Answer:
a
Step-by-step explanation:
0 = m(-2)-6
M = -3
Y = -3x-6
f(x)=-x^2-4x-19
Find f(−9)
Answer:
-64.
Step-by-step explanation:
f(x)=-x^2-4x-19 Replacing x by -9:-
f(-9)= -(-9)^2-4(-9)-19
= -81 + 36 - 19
= 36 - 100
= -64.
Answer:
-64
Step-by-step explanation:
f(x)=-x^2-4x-19
Let x = -9
f(-9) = - (-9)^2 -4(-9) -19
= -81 +36 -19
=-64
A ant has six legs how many legs do eight ants have
Answer:
48
Step-by-step explanation:
In this problem, you need to find out how many total legs 8 ants would have together. Each ant has 6 legs; this means that to solve you must add 6 together 8 times. However, there is an easier way to do this. You can also multiply 6 by 8 to get the same answer. The answer is 48.
f(x) = -2x - 7 and g(x) = x+8/x find (g of f) (-7)

Find the are of the shaded region
square root of the quantity x minus 2 end quantity plus 8 equals x
solve for x
Answer:
x = 11.
Step-by-step explanation:
√(x - 2) + 8 = x
√(x - 2) = x - 8
Square both sides:
x - 2 = (x - 8)^2
x - 2 = x^2 - 16x + 64
x^2 - 17x + 66 = 0
(x - 6)(x - 11) = 0
x = 6, 11.
With this type of question we could have extraneous roots so:
Check these 2 roots:
x = 6:
√(2 - 6) + 8 = √(-4)+8 <----- has no real value so this is not a root,
x = 11:
√(11-2) + 8 = 11 < ----Checks out.
Answer:
x = {6, 11}Step-by-step explanation:
[tex]\sqrt{x-2} + 8=x[/tex][tex]\sqrt{x-2} = x - 8[/tex]x - 2 = (x - 8)²x² - 16x + 64 = x - 2x² - 17x + 66 = 0x = (17 ± [tex]\sqrt{17^2- 4*66}[/tex]) / 2x = (17 ± 5)/2x = 11x = 6Point C is located between points B and D. Also BC = 5x + 7, CD = 3y + 4, BD = 38, and BD = 2x + 8y. Find the values of x and y
Using location of points and a system of equations, it is found that:
The value of x is 3.The value of y is 4.----------------------------------
Point C is located between points B and D means that:
[tex]BD = BC + CD[/tex]
----------------------------------
We are given that:
[tex]BC = 5x + 7[/tex][tex]CD = 3y + 4[/tex][tex]BD = 38[/tex][tex]BD = 2x + 8y[/tex]From this, two equations can be built.
[tex]2x + 8y = 38[/tex]
Dividing both sides by 2:
[tex]x + 4y = 19[/tex]
[tex]x = 19 - 4y[/tex]
----------------------------------
Finding y:
[tex]BC + CD = BD[/tex]
[tex]5x + 7 + 3y + 4 = 38[/tex]
[tex]5x + 3y + 11 = 38[/tex]
[tex]5x + 3y = 27[/tex]
Since [tex]x = 19 - 4y[/tex]
[tex]5(19 - 4y) + 3y = 27[/tex]
[tex]95 - 20y + 3y = 27[/tex]
[tex]17y = 68[/tex]
[tex]y = \frac{68}{17}[/tex]
[tex]y = 4[/tex]
----------------------------------
Finding x:
[tex]x = 19 - 4y = 19 - 4(4) = 19 - 16 = 3[/tex]
The value of x is 3.
The value of y is 4.

answer choices:
a. 4
b. 7
c. -4
d. 6
Answer:
answer by your own
Step-by-step explanation:lol
Answer:
D.
Step-by-step explanation:
The first step is to subtract 2 on both sides, so
3(y - 5) + 2 - 2 = 5 - 2
3(y - 5) = 3
Next, multiply by or distribute the 3 on the left side.
3y - 15 = 3
Then, add 15 on both sides.
3y - 15 + 15 = 3 + 15
3y = 18
Finally, divide by 3 on both sides.
3y/3 = 18/3
y = 6

1)what is the measure of the segment AB
2)what is the measure of segment CD
how so?
Answer:
AB = 18, CD = 16
Step-by-step explanation:
The 3 segments make the whole line , that is
AB + BC + CD = AD , substitute values
AB + 20 + (BD - BC) = 54
AB + 20 + (36 - 20) = 54
AB + 20 + 16 = 54
AB + 36 = 54 ( subtract 36 from both sides )
AB = 18
-----------------------------------------------------
BC + CD = BD , substitute values
20 + CD = 36 ( subtract 20 from both sides )
CD = 16
