The Native American population in state A and B is 282,000 and 94,000 respectively.
Here, we are given that State A's population of Native Americans is three times the Native American population of State B.
Let the Native American population in state B be x
Thus, the Native American population in state A will be 3x
Total Native American population in state A and B = 376,000
Thus, we can get the following equation-
x + 3x = 376,000
4x = 376,000
x = 376,000/ 4
x = 94,000
⇒ 3x = 3 × 94,000
3x = 282,000
Thus, the Native American population in state A and B is 282,000 and 94,000 respectively.

If y is directly proportional to x and y =1200 when x=30, then what is the value of x when y=30?
Answer:
Y= 30
X= 0.75
Step-by-step explanation:
If the first Y was 1,200 and X was 30, then that means every time your divide Y by 40, you will get your X. It's the exact opposite if you want to find Y.
So you want to divide your Y, which is 30, by 40. Once who find your answer, you should have gotten 0.75 for X.
Why divide by 40? Good question. You divide by 40 because if you multiply your X example Y= 1,200, X= 30, you will get 30x40 which is 1,200. Do it the other way around divide 1,200 by 40, you get 30.
All in all your answer should be X= 0.75. If not tell me.

Figure ABCD is a rhombus. Find the value of x.
The value of x is 32 degrees.
Rhombus
A rhombus is a special case of a parallelogram. In a rhombus, opposite sides are parallel and the opposite angles are equal. The rhombus is also called a diamond or rhombus diamond.
It is given in the question that there is a rhombus ABCD with ∠ DAC = 58 degrees.
We have to find the angle x or ∠ ADB.
We know the property that the diagonals of the rhombus perpendicularly bisect each other.
Hence, the rhombus is divided into 4 right triangles.
Hence,
∠DAC + ∠ADB = 180 - 90 = 90 degrees
58 + x = 90 degrees
x = 90 - 58
x = 32 degrees.

Suppose a and b are positive integers such that lcm(a,b) = 90 and gcd(a,b) = 3. If b is three more than a, then what are the values of a and b?
Given:
LCM(a,b) = 90 and GCD(a,b) = 3.
b is three more than a.
To find:
The values of a and b.
Solution:
We have,
LCM(a,b) = 90
GCD(a,b) = HCF(a,b) = 3
According to the question,
[tex]b=a+3[/tex]
If a and b are two positive integers, then
[tex]a\times b=HCF(a,b)\times LCM(a,b)[/tex]
[tex]a\times (a+3)=3\times 90[/tex]
[tex]a^2+3a=270[/tex]
[tex]a^2+3a-270=0[/tex]
Splitting the middle terms, we get
[tex]a^2+18a-15a-270=0[/tex]
[tex]a(a+18)-15(a+18)=0[/tex]
[tex](a+18)(a-15)=0[/tex]
Using zero product property, we get
[tex]a+18=0[/tex] and [tex]a-15=0[/tex]
[tex]a=-18[/tex] and [tex]a=15[/tex]
a is a positive integer so it cannot be negative. So, a=15.
Now,
[tex]b=a+3[/tex]
[tex]b=15+3[/tex]
[tex]b=18[/tex]
Therefore, the value of a is 15 and the value of b is 18.

what equation is equal to the x axis x = 4, x +y = o, x = y, y = 4
The x-axis is equivalent to x = 4, x + y = 0, x = y, and y = 4, and the value of the x-axis is y = 0.
What is equivalent?Expressions that are equivalent do the same thing even when they have distinct appearances.. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s)
The Cartesian plane is what?A coordinate system is a plane with Cartesian coordinates. Each point is uniquely identified by a pair of numerical coordinates that are the signed distances from two fixed perpendicularly oriented lines to the point, measured in the same unit of length.Given that all of the y-values on the x-axis are zero, the x-axis' equation is y = 0.Similar to the x-axis, the y-axis also has all zero values, therefore the equation of the y-axis is x = 0.((This presupposes that we're referring to the Cartesian plane, i.e. we are limiting ourselves to two dimensions.)

What is the value of x, y, z? Please answer need help soon
Answer:
x = 55
y = 55
z = 70
Step-by-step explanation:
x + 125 is a straight line, 180⁰ x+125=180 x=55⁰
since this is an isosceles triangle, x = z
and the sum of all angles in any triangle is 180⁰
55+55+y=180⁰
y = 70⁰
Answer:
x=55º, y=70º, z=55º
Step-by-step explanation:
We have that xº = 180º - 125º = 55º
As it is an isosceles triangle, we have xº = zº = 55º
Therefore, yº = 180º - (xº + zº) = 180º - (55º + 55º) = 180º - 110º = 70º

[tex]\frac{x}{2}-\frac{2}{x+1}=1[/tex]
We have 2 denominators that we need to get rid of. Whenever there are the denominators, all we have to do is multiply all whole equation with the denominators.
Our denominators are both 2 and x+1. Therefore, we multiply the whole equation by 2(x+1)
[tex]\frac{x}{2}[2(x+1)]-\frac{2}{x+1}[2(x+1)] = 1[2(x+1)][/tex]
Then shorten the fractions.
[tex]\frac{x}{2}[2(x+1)]-\frac{2}{x+1}[2(x+1)] = 1[2(x+1)]\\x(x+1)-2(2)=1(2x+2)[/tex]
Distribute in all.
[tex]x^2+x-4=2x+2[/tex]
We should get like this. Because the polynomial is 2-degree, I'd suggest you to move all terms to one place. Therefore, moving 2x+2 to another side and subtract.
[tex]x^2+x-4-2x-2=0\\x^2-x-6=0\\[/tex]
We are almost there. All we have to do is, solving for x by factoring. (Although there are more than just factoring but factoring this polynomial is faster.)
[tex](x-3)(x+2)=0\\x=3,-2[/tex]
Thus, the answer is x = 3, -2

Step-by-step explanation:
Given that;
The results are
ABC : 41
BAC : 26
CAB : 42
NOW
A>B>C = 41 ⇒ A has 41 votes
B>A>C = 26 ⇒ B has 26 votes
C>A>B = 42 ⇒ C has 42 votes
According to Hare method, least votes gainers will be eliminated and once eliminated, his/her/its votes will be transferred to the next choice of person/thing.
based on the question; B will be eliminated
so we have;
A>B>C = 41 ⇒ A has 41 votes
B>A>C = 26 ⇒ B has 26 votes
we eliminate B, the votes are transferred to the next (A)
A>C = 26 ⇒ A has 26 votes
C>A>B = 42 ⇒ C has 42 votes
SO in total
A votes = 41 + 26 = 67 VOTES
Therefore after eliminating B due to Hare Method, A will have a total of 67 VOTES
After eliminating B due to Hare Method, A will have a total of 67 votes
We have given that,the results are
ABC : 41
BAC : 26
CAB : 42
A>B>C = 41 ⇒ A has 41 votes
B>A>C = 26 ⇒ B has 26 votes
C>A>B = 42 ⇒ C has 42 votes
What is the Hare method?
The Hare method is least votes gainers will be eliminated and once eliminated,The votes will be transferred to the next choice of person/thing.
From the given question we have B will be eliminated
Therefore we have
A>B>C = 41 ⇒ A has 41 votes
B>A>C = 26 ⇒ B has 26 votes
We eliminate B, the votes are transferred to the next (A)
A>C = 26 ⇒ A has 26 votes
C>A>B = 42 ⇒ C has 42 votes
Therefore the total votes are
A votes = 41 + 26 = 67 votes
Therefore after eliminating B due to Hare Method, A will have a total of 67 votes.
