A man bought a calf for $200 and sold it for
$250. What was his gain as a percentage of the
cost price?
Answers
Answer:
Step-by-step explanation:
250 is 125% of 200
So,
He gained 25% in profit
Based on the information given his gain as a percentage of the cost price is 25%.
Using this formula
Cost price percentage=Selling price-Cost price/Cost price
Where:
Selling price=$250
Cost price=$200
Let plug in the formula
Cost price percentage=$250-$200/$200
Cost price percentage=$50/200
Cost price percentage=0.25×100
Cost price percentage=25%
Inconclusion his gain as a percentage of the cost price is 25%.

on average, how many times must a 6-sided die be rolled until the sequence 65 appears (i.e., a 6 followed by a 5)?
Answers
A 6-sided die must be rolled 36 times before sequence 65 appears. (i.e., a 6 followed by a 5)
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Let E as the expected rolls, and E₆ as the expected rolls given we rolled a 6.
Given that we rolled a 6, there is a 1/6 chance that two rolls will be enough, a 4/6 chance that we didn't roll a 5 or 6 and so spent two rolls, and a 1/6 chance that we rolled a 6 and only wasted one roll:
E₆ = (1/6)2 + (4/6)(E+2) + (1/6)(E₆ + 1)
Rearrange the terms and apply arithmetics operations
E₆ = (4E + 11)/5
According to the question,
We have 5/6 that we rolled [1,5]
So we wasted a roll, and 1/6 that we rolled a 6,
E = (1/6)×E₆ + (5/6)×(E+1)
Substitute the value of E₆ in the equation,
E = (1/30)×(4E+11) + (5/6)×(E+1)
E = 36
Hence, a 6-sided die must be rolled 36 times before sequence 65 appears.

1. Miguel is taking a quiz that contains 5 questions.
Each question is worth 20 points, with no partial

answered correctly and y represents the number
of points awarded, this function can be
represented by the equation y = 20x.
What is a reasonable domain for this function?
A. x ≤ 5
B. 0≤x≤5
C. {0, 1, 2, 3, 4, 5}
D. {0, 20, 40, 60, 80, 100}
Answers
Answer:
C. {0, 1, 2, 3, 4, 5}
Step-by-step explanation:
There are 6 possible outcomes: 0 points (0 questions correct), 20 points (1 question correct), 40 points (2 questions correct), 60 points (3 questions correct), 80 points (4 questions correct) and 100 points (5 questions correct). The number of points is equal to the number of questions answered times 20. The x value can only be equal to the possible number of questions answered correctly: 0, 1, 2, 3, 4, 5.
A is incorrect because it includes negative numbers and decimals. Decimal values aren't possible because no partial credit is given for the questions. Negative numbers are incorrect because you cannot answer negative questions.
B is incorrect because it includes fractions.
D is incorrect because it lists the y values (what 20x is equal to) instead of the x values.
Find the value of x that will make A parallel to B
2x + 50
5x - 80
x = ?
Answers
Answer:
30
Step-by-step explanation:
If Line A is parallel to Line B, then 2x+50+5x-80 = 180. This is because 2x+50 is an alternate interior angle with the supplement of 5x-80, therefore the supplement of 5x-80 is also 2x+50. Supplementary angles add up to 180°.
Solve the Equation2x + 50 + 5x - 80 = 180 --> Combine like terms
7x - 30 = 180 --> Add 30 to both sides
7x = 210 --> Divide both sides by 7
x = 30
Check the Solution
We can check our answer by plugging 30 in for x back into our original equation.
2(30) + 50 + 5(30) - 80 = 180
60 + 50 + 150 - 80 = 180
110 + 150 - 80 = 180
260 - 80 = 180
180 = 180
Therefore x = 30.

y- 3 = 2(x - 1)
Od
y- 3 = 4(x + 1)
Answers
Answer:
y - 3 = 2(x+1)Step-by-step explanation:
The equation of the line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is a point on the line
Get the slope;
Given the points (-1,3) and (1, 7)
m = y2-y1/x2-x1
m = 7-3/1+1
m = 4/2
m = 2
Substitute the point m = 2 and the point (-1, 3) into the formula above as shown;
y - y0 = m(x-x0)
y - 3 = 2(x-(-1))
y - 3 = 2(x+1)
Hence the required equation is y - 3 = 2(x+1)
What is the value for f(x) =0
Answers
The function can be graphed to demonstrate this further. On the graph where f(x)=0, the curve is just the x-axis, which always has the same y-value of 0.
How to find the domain of a function ?Domaine:The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
Given the function f(x)=0,
since this is a constant function (that is, for any value of x, f(x)=0, the limit of the function as x→a, where a is any real number, is equal to 0.
More specifically, as a constant function,f(x) maintains the same value for any x. f(1)=f(2)=f(π)=f(e)=f(−(1258567)/(44))=0. Further, as a constant function, f(x) is by definition continuous throughout its domain. Note, however, that if one arrives at a constant function via division or multiplication of non-constant functions (for example, (8x)/(x), there will still exist a discontinuity where the original denominator was0).
Graphing the function will further prove this point. On the graph f(x)=0, the curve is simply the x-axis, which maintains a constant y-value of 0 no matter the x-value.

Answers
Figure ABCDE is similar to figure FGHIJ and because corresponding sides have same ratio.
How to Identify Similar Triangles?
Similar triangles are triangles that have the same shape, but their sizes may vary.
In figure ABCDE vertices A,B,C,D,E are given so we can find their sides by applying distance formula:
D=√((x2 - x1)² + (y2 - y1)²)
With the help of this formula we can find AB;
AB = √(-1 - (-3))² + (3 - 1)²)
AB = √((-1 + 3)² + (2)²)
AB = √((2)² + (2)²)
AB = √(4 + 4)
AB = √8
AB = (√2*2) * 2
AB = 2√2
Likewise, we can find the remaining sides as;
BC = 4, CD = √10, DE = √10 and EA = 2√2
FG = √2, GH = 2,HI = 1.58114, IJ = 1.58114 and JF = √2
When the two figures are similar then the ratios of their corresponding sides are equal.
Thus, we have that;
AB/FG = BC/GH = CD/HI = DE/IJ = EA/JF
Therefore, we conclude that figure ABCDE is similar to figure FGHIJ and because corresponding sides have same ratio.

Despite there only being one line shown, there are actually two lines here. One just happens to be directly on top of the other.
We can see this by noting that 2y = 3x-1 turns into 4y = 6x-2 when we multiply both sides by 2. Multiplying both sides by the same number keeps the same equation, so that's why we have identical graphs.
The two identical graphs intersect each other infinitely many times, leading to infinitely many solutions. All solutions are (x,y) points on the blue line. Two such solutions are (1,1) and (3,4). All solutions are of the form [tex]\left(x, \frac{3x-1}{2}\right)[/tex]
Tommy has $350 of his graduation gift money saved at home in the amount is modeled by the function h(x)=350. He reads about a bank that has savings account that accrue interest according to the function s(x)=(1.04))^x-1. Explain how Tommy can combine the two functions to model the total amount of money he will have in his bank account as interest accrues after he deposit his $350 justify your reasoning
Answers
Answer:
Step-by-step explanation:
His functions are:
h(x)= $350
s(x)=(1.04))^x-1
To find total amount of money in Tommy's account using the functions above, we substitute the first function x= $350 in the second function
So, we can say that the new function represents the interest received by
Tommy with initial saving $350.
Function:A function is a group of statements that together perform a task.
Given that Tommy got $350 as the gift which he saves.
So, the amount saved is given by the function is [tex]h(x)=350....(1)[/tex]
Also, the interest by the saving bank account is given by,
[tex]s(x)=(1.04)^{x-1}....(2)[/tex]
Comparing equations (1) and (2) we get a new function as,
[tex]g(x)=350(1.04)^{x-1}[/tex]
The function gives the value [tex]h(x)=350[/tex] when [tex]x=0[/tex] and the amount is increasing by the interest.

Which is taller, the Burj Khalifa or a stack of the money it cost to build the Burj Khalifa

The structure known as the Burj Khalifa is taller than a stack of the money it took to construct it.
What is Burj Khalifa?The Burj Khalifa is an iconic skyscraper in Dubai, United Arab Emirates. With a height of 828 meters (2,716 ft), it is now the highest structure in the world.
The Burj Khalifa's construction began in 2004 and was finished in 2009. The skyscraper was constructed by the architectural firm Skidmore, Owings & Merrill and was mostly funded by the government of Dubai.
The Burj Khalifa stands 828 meters (2,716 ft) tall. According to sources, the overall cost of constructing the Burj Khalifa was around $1.5 billion USD. A stack of $1.5 billion USD would be roughly 165 metres (541 feet) tall if the typical US $100 bill has a thickness of 0.11 millimeters.
