Elis, Raine and Avery buy a boat for $33 000.
Elise pays $12 000, Raine pays $6000 and Avery pays the rest.
Six years later they sell the boat for $25 300.
They share the money in the same ration that they bought the boat.
How much money does Avery lose on the sale of the boat?
Answers
Amount Avery paid: 32,000-12,000-6,000 = 15,000
Divide portion she paid by total cost:
15,000/33,000
Simplify to 15/33
Multiply the amount the boat was sold for by her portion:
25,300 x 15/33 = 11,500
Subtract the amount she got from the amount she paid:
15,000 - 11,500 = 3,500
She lost $3,500
Answer:
yes
Step-by-step explanation:
yes!

[tex]\huge\boxed{\text{B) 4}}[/tex]
Step-by-step explanation:
We can use the properties of some of these circles to solve and find the value of x.
FIrst off - we know that to find the side of a right triangle we can use the Pythagorean Theorem, which states that [tex]a^2 + b^2 = c^2[/tex] (a and b being legs, c being the hypotenuse.)
Finding the hypotenuseWe also know that this triangle is in a circle. Part of the hypotenuse and the altitude of the triangle are in the circle.
Point W is the center of the circle. Therefore, any points stretching to the edge from it will be equal (since this is a circle).
With this knowledge - UW and WZ are equal.
Therefore, since UW is [tex]x-1[/tex], WZ will be too.
We also know the length of VZ. We can add this to WZ to find the length of the whole hypotenuse.
[tex]\displaystyle x-1+2 \\ x+1[/tex]
So the length of the hypotenuse, WV, is [tex]x+1[/tex].
Finding the value of xNow that we know the length of the hypotenuse, we can use the Pythagorean Theorem like we stated before to find the value of x.
We know the two legs are [tex]x-1[/tex] and [tex]2x-4[/tex], while the hypotenuse is
[tex]\displaystyle (x-1)^2 + (2x-4)^2 = (x+1)^2[/tex] [tex](x^2 - 2x + 1) + (4x^2-16x+16) = (x^2 + 2x + 1)[/tex] (use FOIL to find the value of each expression squared) [tex]5x^2 - 18x + 17 = x^2 + 2x + 1[/tex] (simplify the left side) [tex]4x^2 -20x + 16 = 0[/tex] (subtract both sides by [tex]x^2 +2x + 1[/tex]) [tex]x = \frac{{ -b \pm \sqrt {b^2 - 4ac} }}{{2a}}[/tex] (Quadratic formula) [tex]\frac{{ -(-20) \pm \sqrt {(-20)^2 - 4 \cdot 4 \cdot 16} }}{{2 \cdot 4}}[/tex] (plug in values from equation) [tex]\frac{{ 20 \pm \sqrt {400 - 256} }}{8}}[/tex] (simplify) [tex]\frac{{ 20 \pm \sqrt {144} }}{8}}[/tex] (simplify) [tex]\frac{{ 20 \pm 12 }}{8}}[/tex] (simplify) [tex]\displaystyle x = \frac{20+12}{8} \ \text{and} \ \frac{20-12}{8}[/tex] (use plus/minus to find two roots) [tex]\displaystyle x = \frac{32}{8} \ \text{and} \ \frac{8}{8}[/tex] (simplify) [tex]\displaystyle x = 4 \ \text{and} \ 1[/tex]1 can not be a possible answer because UW would end up being [tex](1-1) = 0[/tex] units long! This isn't possible!
Therefore, the correct answer would be B) 4.

A) 5.04 x 102 particles
B) 5.46 x 1012 particles
C) 6.04 x 1013 particles
D) 6.44 x 1013 particles
Answers
Answer: 5.04x[tex]10^{4}[/tex] particles
in your situation is choose : A
Step-by-step explanation:
the volume of the living room is 1,400[tex]m^{3}[/tex], and there are 3.6 x [tex]10^{1}[/tex] particles of dust / [tex]m^{3}[/tex]
we will convert the room volume to scientific notation = 1.4 x [tex]10^{3}[/tex][tex]m^{3}[/tex]
then, the total number of particles will be the product of the two numbers, which is 1.4 x [tex]10^{3}[/tex][tex]m^{3}[/tex] times 3.6 x [tex]10^{1}[/tex] particles/[tex]m^{3}[/tex] = 5.04x[tex]10^{4}[/tex] particles

Is x=3, y=2 a solution to the system of equations shown? Justify your answer.
y = 2x - 4
3x + 2y = 8
Answers
3(3)+2(2)=8=12
Answer:
It is not a solution.
Step-by-step explanation:
y = 2x - 4
2 = 2(3) - 4
2 = 6 - 4
2 = 2
The point is a solution to the first equation.
3x + 2y = 8
3(3) + 2(2) = 8
9 + 4 = 8
11 ≠ 8
The point is only a solution for one equation. It is not a solution to the system.
Hope this helps.

Answer and Step-by-step explanation:
The independent variable is m, and the dependent variable is h.
This is because you can plug in any value for m, making m NOT have to depend on any other value to become m.
With h, it needs the result of m and its other values to become the result of h. H relies/depends on the values in the equation to become a value.

Answers
Answer:75
Step-by-step explanation:
180-64 gives you the angle not labelled which is 116 then to work out size of angle formula is 180(n-2) n being sides so 180(6-2) = 720 so 720 minus all the angles = 75 I think lol
Answer:
x = 75
Step-by-step explanation:
180-64 = 116
Since this is a hexagon (6 vertices), the angles all add up to 720
116 + 121 + 155 + x + 90 + 163 = 720
x + 645 = 720
x = 75

translate the figure 3 units right and 7 unit down.Record the coordinates of the image.
Answers
Answer: A prime is (-4,-5). B prime is (0,-1). C prime is (1,-5)
Step-by-step explanation:
You can either count three units to the right and from there 7 units down from each point to find its prime, or alternatively from each original x,y value of each point you can add 3 to the x value (because it wants you to move 3 units to the right and subtract 7 from the y value (because it wants you to move down 7 units).
An electronic device factory is studying the length of life of the electronic components they produced. The manager selects two assembly lines and takes all samples on those two lines. He got a sample of 500 electronic components and records the length of life in the life test. A histogram indicates that the lifespans have moderate right skew. From the sample he found the average length of life was 200,000 hours and that the standard deviation was 1,000 hours. He wants to find the confidence interval for the average length of life of the electronic components they produced. Based on the information, what advice will you give to him
Answers
Answer:
The confidence interval will be given by:
[tex]200000 \pm 44.72z[/tex], in which z is related to the confidence level.
For a confidence level of x%, z is the value in the z-table that has a pvalue of [tex]1 - \frac{1 - z}{2}[/tex]
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In the context of this problems:
It means that the sampling distributions of the sample mean of 500 components will be approximated normal, with mean 200,000 and standard deviation [tex]s = \frac{1000}{\sqrt{500}} = 44.72[/tex]
To build the confidence interval:
The confidence interval for the average length of life of the electronic components they produced will be given by:
[tex]200000 \pm 44.72z[/tex], in which z is related to the confidence level.
For a confidence level of x%, z is the value in the z-table that has a pvalue of [tex]1 - \frac{1 - z}{2}[/tex]
