how to solve Davis bought a second hand cycle for $500 he spent $80 in repairs and $175 in repainting he then sold it to John for $900 how much did he gain or lose?
Davis spent a total of $755 on buying and refurbishing the cycle, which he sold for $900. He made a gain of $145 on the sale.
Explanation:To calculate Davis's gain or loss from buying and selling the second-hand cycle, we need to determine the total cost he incurred and compare that to the sale price. First, we add the purchase price of the cycle to the cost of repairs and repainting:
Purchase price: $500Repairs: $80Repainting: $175The total cost Davis incurred is $500 + $80 + $175, which equals $755.
Next, we must compare this to the sale price, which is $900. To find the gain, we subtract the total cost from the sale price:
$900 - $755 = $145
Therefore, Davis made a gain of $145 from this transaction.
Davis gained $145 by selling the cycle for $900 after incurring a total expense of $755 on its purchase, repairs, and repainting.
To calculate whether Davis made a gain or a loss from buying and selling the cycle, we need to consider the total cost of the cycle (including repairs and repainting) and the selling price. First, we add up the initial cost of the cycle ($500), the cost of repairs ($80), and the cost of repainting ($175). This will give us the total cost. Then, we subtract this total cost from the selling price ($900).
Total cost = Cost of cycle + Repairs + Repainting = $500 + $80 + $175 = $755
Profit or Loss = Selling price - Total cost = $900 - $755
Profit or Loss = $900 - $755 = $145
Davis gained $145 from this transaction because the selling price was higher than the total cost.
Suppose that in a particular country, the probability that a randomly chosen person is a left-handed baseball player is 0.017 and the probability that a randomly chosen baseball player is left-handed is 0.250. Based on these probabilities, determine the probability, , that a randomly chosen person from this country plays baseball. Give your answer as a decimal precise to at least three decimal places.
To find the probability of a randomly chosen person playing baseball in a country, you need to use the given probabilities and conditional probability formula.
Explanation:To find the probability that a randomly chosen person from this country plays baseball, denoted as B:
Let A be the event that the person is left-handed and plays baseball.Use the formula for conditional probability: P(A|B) = P(A and B) / P(B).Calculate P(B) = P(A and B) + P(not A and B) using the given probabilities.Substitute the values to find the probability that a randomly chosen person from this country plays baseball.The probability that a randomly chosen person from the country plays baseball is 0.068.
To find the probability that a randomly chosen person from a particular country plays baseball, we will use the given information and apply Bayes' theorem.
We are given:
The probability that a randomly chosen person is a left-handed baseball player (P(L and B)) is 0.017.The probability that a randomly chosen baseball player is left-handed (P(L | B)) is 0.250.We are asked to find the probability that a randomly chosen person is a baseball player (P(B)).
Using Bayes' theorem, we can express P(B) as P(L and B) / P(L | B). Plugging in the known values:
P(B) = P(L and B) / P(L | B) = 0.017 / 0.250 = 0.068
Therefore, the probability that a randomly chosen person plays baseball is 0.068, precise to three decimal places.

Answer:
D
Step-by-step explanation:
If you drew a line of best fit to encompass all the data points it would be a line that has a negative slope. The correlation coefficient would be negative.
The option (D) the data shows a negative linear relationship because the slope of the line is negative.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
As we can see in the picture, the dots pattern are going up to down if we draw a line of best fit.
The slope of the line will be negative.
We can say the relationship between car's value and car's age is negative correlated.
Thus, the option (D) the data shows a negative linear relationship because the slope of the line is negative.

A 4-digit number ends in 3. If you put the number 3 in the first position, the number will decrease by 738. Find the original 4-digit number.
Answer:
4153
Step-by-step explanation:
Let the original number be [tex]\overline{abc3}[/tex] [a is the number of thousands, b - the number of hundreds, c - the number of tens, 3 - the number of ones]
If you put the number 3 in the first position, the number will be [tex]\overline{3abc}[/tex]
New number is 738 less than old number.
When you subtract from 3 some number c and get 8, then you have to lend one ten and subtract this number c from 13. So, 13-5=8. Thus, c=5. Remember about lending! Now when you subtrat from 4 (not 5 because of lending) some number b and get 3, then b=1. Now when you subtract from 1 some number a and get 7, then you have to lend 1 from the number of thousands and subtract a from 11 to get 7, thus 11-4=7 and a=4.
We get initial number 4153 and rewritten number 3415. Check the difference:
4153-3415=738

Constants = 10
Hope this helped! :)
In the expression 3x+10, there are two terms: 3x and 10. The coefficient is 3, which multiplies the variable x, and the constant is 10, which is the term without a variable.
In the expression 3x+10, the terms are 3x and 10. A term is a single mathematical expression. The coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression, so here the coefficient is 3, which is the number multiplying the variable x. The constant is a term without a variable, and in this case, it is 10.
What is the exact value of cos 45º ?
Enter your answer, as a simplified fraction, in the box.
Answer:
(√2)/2
Step-by-step explanation:
A right triangle with one acute angle equal to 45° will also have the other acute angle equal to 45°. The angles being equal means the legs will be equal. If we assign each leg the length 1, then the Pythagorean theorem tells us the hypotenuse is length ...
√(1^2 +1^2) = √2
The cosine of the acute angle is the ratio of the nearest leg length (1) to the hypotenuse length (√2), so the exact value of the cosine is ...
cos(45°) = 1/√2 = (√2)/2

(√2)/2 is the fraction with the denominator "rationalized". Sometimes, that is the preferred presentation of this number.

A bridge crosses a circular lake. The bridge is represented by the function y −x = 2 and the lake is represented by the function x^2 +y ^2 = 100.
a. What is the radius of the lake?
b. Find the length of the bridge.
We can rewrite the equation of the circle as
[tex](x-0)^2+(y-0)^2=10^2[/tex]
so that we can be in the form
[tex](x-h)^2+(y-k)^2=r^2[/tex]
When you write the equation of a circle in this form, then the center is [tex](h,k)[/tex] and the radius is [tex]r[/tex].
So, in our case, the radius of the circle is 10.
To find the length of the bridge, we find the two points where the bridge crosses the lake (i.e. we solve the system between the equations of the line and the circle), and compute the distance between those points:
[tex]\begin{cases}y=x+2\\x^2+y^2=100\end{cases}\implies\begin{cases}y=x+2\\x^2+(x+2)^2=100\end{cases}[/tex]
Solving the second equation for x, we have
[tex]x^2+(x+2)^2=100 \iff x^2+x^2+4x+4=100\iff\\2x^2+4x-96=0 \iff x^2+2x-48=0\\\iff x=-8\ \lor\ x=6[/tex]
We use the first equation to compute the correspondent values of y:
[tex]x=-8\implies y=x+2=-6 \implies P_1 = (-8,-6)[/tex]
[tex]x=6\implies y=x+2=8 \implies P_1 = (6,8)[/tex]
Now, the distance between these two points is given by the pythagorean's theorem:
[tex]d = \sqrt{(-8+6)^2+(-6+8)^2} = \sqrt{4+4}=2\sqrt{2}[/tex]
The radius of the lake is 10 units. The length of the bridge is 14√2 units. We found this by solving the equations of the circle and the line representing the bridge.
The equation of the circular lake is given as [tex]x^2 + y^2 = 100[/tex] . This equation is of the form [tex](x -b)^2 + (y - c)^2 = r^2,[/tex] where the center of circle is at (b, c) and the radius is r. In this case, the center is at (0, 0), and the radius squared is 100. Therefore, the radius (r) is:
r = √100 = 10
So, the radius of the lake is 10 units.
The bridge is represented by the function y - x = 2, which can be rewritten as y = x + 2.
To find the points of intersection between this line and the circle, substitute y = x + 2 into the circle's equation
[tex]x^2 +[/tex][tex]y^2 = 100:[/tex]
[tex]x^2 + (x + 2)^2 = 100[/tex]
Simplify this to:
[tex]x^2 + x^2 + 4x + 4 = 100[/tex]
[tex]2x^2 + 4x + 4 = 100[/tex]
[tex]2x^2 + 4x - 96 = 0[/tex]
Divide everything by 2:
[tex]x^2 + 2x - 48 = 0[/tex]
To solve this quadratic equation, use the quadratic formula x = (-b ± √([tex]b^2[/tex] - 4ac))/(2a), where a = 1, b = 2, and c = -48:
x = (-2 ± √([tex]2^2[/tex] - 4*1*(-48)))/(2*1)
x = (-2 ± √(4 + 192))/2
x = (-2 ± √196)/2
x = (-2 ± 14)/2
This results in two solutions:
x = (12)/2 = 6
x = (-16)/2 = -8
Thus, the points of intersection are (6, 8) and (-8, -6).
Finally, to find the length of the bridge, calculate the distance between these two points using the distance formula: d = [tex]\sqrt{ ((x2 - x1)^2 + (y2 - y1)^2)[/tex]
[tex]d = \sqrt{((6 - (-8))^2 + (8 - (-6))^2)[/tex]
[tex]d = \sqrt{((6 + 8)^2 + (8 + 6)^2)[/tex]
d = [tex]\sqrt{(14^2 + 14^2)[/tex]
d = [tex]\sqrt{(196 + 196)[/tex]
[tex]d = 14\sqrt{2}[/tex]
Therefore, the length of the bridge is [tex]14\sqrt{2}[/tex] units.

what is the equation of the line that is parallel to the line y= 3x-4 and passes through the point (4, -2)
Answer:
y = 3x - 14
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 4 is in this form with slope m = 3
• Parallel lines have equal slopes, hence
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (4, - 2) into the partial equation
- 2 = 12 + c ⇒ c = - 2 - 12 = - 14
y = 3x - 14 ← equation of parallel line
The line that is parallel to y=3x-4 and passes through the point (4,-2) has the equation y=3x - 14. This is determined by knowing that parallel lines have the same slope and using the point-slope form of a line equation.
Explanation:In Mathematics, two lines are parallel if they have the same slope. The line provided in this case is y=3x-4. The slope is 3, which we identify by taking the coefficient of x. Thus, any line parallel to this one will also have a slope of 3.
We also know the line we're seeking passes through the point (4,-2). We will use the point-slope form of a line equation, which is y - y1 = m(x - x1), where m is the slope, and (x1,y1) is a point on the line. Substituting the known values, we get: y - (-2) = 3(x - 4).
Simplifying this equation gives us the equation of the line that is parallel to y = 3x - 4 and passes through the point (4,-2) as: y = 3x -14.

Final answer:
The scale factor from Solid A to Solid B is found by taking the cube root of the ratio of their volumes, resulting in approximately 0.6996.
Explanation:
The question involves finding the scale factor between two similar solids based on their volumes. Since the volumes of similar solids are related by the cube of the scale factor, we can find the scale factor by taking the cube root of the ratio of their volumes. Solid A has a volume of 171.5 m³, and Solid B has a volume of 500 m³. To find the scale factor from Solid A to Solid B, we calculate the cube root of (171.5/500), which will give us the linear scale factor.
The formula we use is:
Scale Factor (k) = ∛(Volume of Solid A / Volume of Solid B)
k = ∛(171.5 m³ / 500 m³)
k ≈ ∛(0.343) ≈ 0.6996
Therefore, the scale factor of Solid A to Solid B is approximately 0.6996.
