A man bought a calf for $200 and sold it for
$250. What was his gain as a percentage of the
cost price?
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%.

Answer:
for every 2 seniors there are 3 juniors or 2:3
The ratio of seniors to total students will be 2: 5.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
There are 10 seniors and 15 juniors in a gym class.
The total number of students will be given as,
Total students = 10 + 15
Total students = 25
Then the ratio of seniors to total students will be given as,
Ratio = Seniors / Total student
Ratio = 10 / 25
Ratio = 2 / 5
The ratio of seniors to total students will be 2: 5.

What is the difference between an equation and an inequality?
a - an equation includes numbers, but an inequality doesn't
b- an inequality includes numbers, but an equation doesn't
c- an equation includes an equal sign, but an inequality doesn't
d- an inequality includes an equal sign, but an equation doesn't
Answer:
The correct answer should be C. Hope I helped.
Answer:
C - an equation includes an equal sign, but an inequality doesn't
Step-by-step explanation:
Although both equations and inequalities are ways to show how expressions relate to one another, an equation is the relationship between expressions with an equals sign ( [tex]=[/tex] ) between them, however, an inequality is a way to express two or more expressions with [tex]<[/tex], [tex]\leq[/tex], [tex]>[/tex] or [tex]\geq[/tex] between them. They both include numbers, so the correct option is C.

Bob and Alice have designed and created a website for their high school. The first week they had 5 visitors to the site; the second week, they had 10 visitors; and during the third week, they had 20 visitors. If the trend continues, how many visitors can they expect in the fifth week? Explain your answer.
Answer:
80 visitors
Step-by-step explanation:
From the above question, we can see that:
The trend is explained using geometric sequence
The formula for Geometric sequence is given as:
an = ar ^n - 1
Where a = first term
r = common ratio
n = number of terms
an = nth term
From the above question, let the number of term be equal to the number of weeks.
First week = First term = 5
Second week = Second term = 10
Third week = Third term = 20
Common ratio = a2/a1 = a3/a2 = 10/5 = 20/10 = 2
We are to find the number of visitors for the Fifth week = fifth term,
Hence:
a5 = 5 × 2^5 - 1
a5 = 5 × 2^4
a5 = 80 visitors
The number of visitors we can expect for the fifth week = 80 visitors

The graph shows the location of point P and point R. Point R is on the y-axis and has the same y-coordinate as point P. Point Q is graphed at (n,-2). The distance from point P to point Q is equal to the distance from point P to point R. What is the from point P to point Q? What is the value of N? Explain how you determined the distance from point P to point Q, and the value of N.
Answer:
n = 5
Step-by-step explanation:
Coordinate of P = (n,3)
R is on y-axis & the y-coordinate of P & R are equal. So coordinate of R = (3,0)
Coordinate of Q = (n,-2)
Using distance formula,
Distance between P & Q =
[tex] \sqrt{ {( n - n}) ^{2} + {( 3- ( - 2) })^{2} } [/tex]
[tex] = > \sqrt{ {(3 + 2)}^{2} } = \sqrt{ {5}^{2} } = 5[/tex]
Distance between P & R =
[tex] \sqrt{ {(n - 0)}^{2} + {(3 - 3)}^{2} } [/tex]
[tex] = > \sqrt{ {n}^{2} } = n[/tex]
But in question it is given that distance between P & Q is equal to the distance between P & R. So,
[tex]n = 5[/tex]
write the equation for this line in slope intercept form
Answer:
y = [tex]\frac{3}{2}[/tex]x + 2
Step-by-step explanation:
Slope-intercept form is y = mx + b with m as the slope and b as the y-intercept.
The y-intercept is the point where the line intersects the y- axis.
y = mx + 2
The equation to find slope is [tex]\frac{y1-y2}{x1-x2}[/tex] Two points from the line: (0,2) (4,8)
[tex]\frac{8-2}{4-0}[/tex] = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]
y = [tex]\frac{3}{2}[/tex]x + 2
