A recent survey found that 5% of the population of the United States is unemployed. If Charlotte, North Carolina, has 30,850 unemployed, what is the population of Charlotte?
The population of Charlotte, North Carolina is approximately_____?
Answer:
617000
Step-by-step explanation:
Division reverses multiplication.
If the total population of Charlotte which we'll call 'x' follows
x * 0.05 = 30850, then
30850 / 0.05 = x
x = 617000

Answer: 4n-7
Step-by-step explanation:
Find the measure of each angle.
x - 7
X
x + 10
Answer:
x - 7: 52
x: 59
x + 10: 69
Step-by-step explanation:
Since we have a straight line, we know that the angles must add up to 180. We can set up an equation to solve:
x - 7 + x + x + 10 = 180
Combine like terms:
3x + 3 = 180
Subtract 3 on both sides:
3x = 177
Divide by 3 on both sides:
x = 59
Now plug in 59 for each angle.
The "x - 7" angle should equal 52, the "x" angle should equal 59, and the "x + 10" angle should equal 69.
Answer:
52°, 59°, and 69°
Step-by-step explanation:
Each of these angles add up to make a straight line, or = 180°
(x - 7) + x + (x + 10) = 180
3x + 3 = 180
3x = 177
x = 59
Angle A = 52°
Angle B = 59°
Angle C = 69°
52 + 59 + 69 = 180!
4(x+5)=6(x+4) what is x
Answer:
x = -2
Step-by-step explanation:
1) Distribute
4(x+5)=6(x+4)
4x+20=6(x+4)
2) Distribute
4x+20=6(x+4)
4x+20=6x+24
3) Subtract 20 from both sides
4x+20=6x+24
4x+20-20=6x+24-20
4) Simplify
- Subtract the numbers
4x+20-20=6x+24-20
4x=6x+24-20
- Subtract the numbers
4x = 6x + 24 - 20
4x = 6x + 4
5) Subtract 6x from both sides
4x = 6x + 4
4x - 6x = 6x + 4 - 6x
6) Simplify
- Combine like terms
4x-6x = 6x + 4 - 6x
-2x = 6x + 4 - 6x
- Combine like terms
-2x = 6x + 4 - 6x
-2x = 4
7) Divide both sides by the same factor
-2x = 4
-2x/-2 = 4/-2
8) Simplify
- Cancel terms that are in both the numerator and denominator
-2x/-2 = 4/-2
x = 4/-2
- Divide the numbers
x = 4/-2
x = -2

Here's the solution~
Standard equation of a circle is represented as :
[tex]\qquad \sf \dashrightarrow \:(x - h) {}^{2} + (y - k) {}^{2} = r {}^{2} [/tex]
where,
h = x - coordinate of center k = y - coordinate of centerradius = diameter/2 = [tex]4\sqrt{3}[/tex]Now, let's plug in the values to find the required equation of circle ~
[tex]\qquad \sf \dashrightarrow \:(x - 8) {}^{2} + (y - ( - 10)) {}^{2} = (4\sqrt{3} ) {}^{2} [/tex]
[tex]\qquad \sf \dashrightarrow \:(x - 8) {}^{2} + (y + 10) {}^{2} = 16 \times 3[/tex]
[tex]\qquad \sf \dashrightarrow \:(x - 8) {}^{2} + (y + 10) {}^{2} = 48[/tex]
The equation of given circle with centre C ( 8 , - 10 ) and diameter ( 8√3 ) is x² + y² - 16x + 20y + 116 = 0
[tex]\quad\rule{300pt}{1pt}\quad [/tex]
Solution:The standard equation of Circle is given by :
[tex] {\pmb{\sf {\longrightarrow r^2 = (x-h)^2 +( y-k)^2}} }[/tex]
This is the standard form of the equation. Thus if we know the coordinates of center of the circle and it's radius, we can easily find its equation
Here, in this question we are given that the centre C is ( 8 , -10 ) and diameter 8√3.
[tex] \longrightarrow[/tex]h = 8
[tex] \longrightarrow[/tex] k = - 10
[tex] \longrightarrow[/tex] r = [tex] \sf{\dfrac{diameter}{2}}[/tex]
[tex] \longrightarrow[/tex] r = [tex] \sf 4\sqrt{3}[/tex]
[tex] \qquad\qquad\rule{250pt}{1pt}\qquad[/tex]
On putting the values in the formula :
[tex] \sf{:\implies \qquad r^2 = (x-h)^2+ ( y-k)^2 }[/tex]
[tex] \sf{:\implies \qquad (4\sqrt{3})^2 = ( x-8)^2 +(y-(-10))^2 }[/tex]
[tex] \sf{:\implies \qquad (4)^2.(\sqrt{3})^2=(x-8)^2+(y+10)^2}[/tex]
[tex] \sf{:\implies \qquad 16\times 3 =( x^2 + 8^2 -2\times x \times 8 ) + ( y^2 + 10^2 + 2\times y \times 10 )}[/tex]
[tex] \sf{:\implies \qquad 48 = x^2 + y^2 - 16x + y^2 + 100 + 20y }[/tex]
[tex] \sf{:\implies \qquad 48 = x^2 + y^2 -16 x + 20y + 100 + 64 }[/tex]
[tex] \sf{:\implies \qquad 48 = x^2 +y^2 -16x +20y +164}[/tex]
[tex] \sf{:\implies \qquad x^2 + y^2 -16x +20y +164 - 48 = 0}[/tex]
[tex] \sf{:\implies \qquad{\boxed{ \sf x^2 + y^2 -16x + 20y +116 = 0 }}}[/tex]
ㅤㅤㅤㅤ~Hence, the required equation of Circle is x² + y² - 10x + 20y + 116 = 0

A local farmer decides to sell his produce at the farmer's market. Every Sunday he uses his own fuel to drive
to the market which is 300km away. This costs him R650.00 per week. He sells 50 boxes of fruit for R250.00
and 100 boxes of fruit for R350.00.
What is the dependent variable in this scenario?
Answer:
The money
Step-by-step explanation:
The drive to the farmers market is a certain distance away, which costs him a specific amount of money. If the distance were to change, then so would the price it took to get there per week. Additionally, as the amount of boxes increases, so does the price.
A dependent variable is a variable that directly changes as the independent variable(s) change. In this scenario, the money, or cost is what's changing based on other factors.

Researchers would like to assess the overall health of white pine trees in a state park. The park has a paved road that runs through the middle of the park. To select trees to assess for damage, the ranger parks at the side of the road and chooses 100 trees near the road to assess for damage. Which of the following statements best describes the bias that may arise from the results?
Because only 100 trees were selected, the overall damage of trees in the park may be underestimated.
The ranger should take another sample of trees near the road and compare it to the first sample to reduce bias.
Because a random sample of trees was chosen, the sample should provide a suitable estimate of the overall health of the trees.
Trees near the road may have more damage than trees away from it, so the results may overestimate the overall damage of the trees.
Trees near the road may have more damage than trees away from it, so the results may overestimate the overall damage to the trees.
What is a random sample space?The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive
Given, The ranger parks at the side of the road and chooses 100 trees near the road to assess for damage hence, trees near the road may have more damage than trees away from it, so the results may overestimate the overall damage of the trees.
So, Consequently, the results can exaggerate the total amount of tree damage.

Write an equation of a parabola that opens upward, has a vertex at the origin, and a focus at (0, 2).
Answer:
Parabola opens upwards, so it's a vertical parabola. Vertex at origin (0,0) and focus at (0,2). Standard equation of this parabola is
| (X — h)^2 = 4p(Y — k) |
Focus is at (0,2), so distance between vertex and focus, which is p is 2 units. So 4p = 8 units.
So the equation of this parabola is,
(X — 0)^2 = 8(Y — 0)
X^2 = 8Y or Y = X^2/8
