Maulik bought two horses at Rs 40,000 each. He sold one horse at 15% gain, but he to sell the second horse at a loss. If he had suffered a loss of Rs 3600 on the Whole transaction, find the selling price of the second horse.
Answer:
Answer is selling price of second horse is Rs 30400.
Step-by-step explanation:
Maulik bought one horse at Rs 40000 and sold it with a gain of 15%
So the selling price of one horse will be 40000+15% of 40000
= 40000+6000
= Rs 46000
Second horse is costing Rs 40000 and had suffered a loss of Rs 3600 on selling both so selling price of both will be = 40000×2-3600
= 80000-3600
= 76400
Now selling price of second horse will be selling price of both - selling price of first = 76400-46000 = Rs 30400
Answer:
The selling price of the second horse is Rs 30,400.
Step-by-step explanation:
Cost Price of first horse([tex]CP_{1}[/tex])= Rs. 40,000
Cost Price of second horse([tex]CP_{2}[/tex])= Rs. 40,000
Total cost price=[tex]CP_{1}+CP_{2}[/tex]=Rs (40,000+40,000)=Rs 80,000
First horse is sold at 15% gain.
This means selling price of first horse([tex]SP_{1}[/tex])= [tex]\dfrac{115}{100} \times40000[/tex]
= Rs. 46,000
also total there is a loss of Rs 3600
selling price of both the horses(SP)=80000-3600=Rs 76400
now, [tex]SP=SP_{1}+SP_{2}[/tex]
where [tex]SP_{2}[/tex] is the selling price of the second horse.
[tex]SP_{2}=SP-SP_{1}[/tex]
[tex]SP_{2}=76400-46000[/tex]
[tex]SP_{2}=30400[/tex]
Hence the selling price of the second horse is Rs 30,400.

Bobby jo made 60 holiday cookies. 4/5 of the cookies are for her teachers and the rest are for her family .How many cookies are for Bobbie jo family
Answer:
12
Step-by-step explanation:
60 divided by 5 is 12, so Bobby jo would give her teachers 48 and 12 to her family
Final answer:
To find the number of cookies for Bobby Jo's family, subtract the number of cookies for her teachers from the total number of cookies she made.
Explanation:
To find the number of cookies for Bobby Jo's family, we need to subtract the number of cookies for her teachers from the total number of cookies she made. Bobby Jo made 60 holiday cookies and 4/5 of these are for her teachers. To calculate the number of cookies for her teachers, we multiply 60 by 4/5:
Number of cookies for her teachers = 60 x 4/5 = 48 cookies
Since the rest of the cookies are for her family, we subtract the number of cookies for her teachers from the total number of cookies to find the number of cookies for her family:
Number of cookies for her family = 60 - 48 = 12 cookies

What is the equation of the height of a roller coaster that is 30 feet above the ground, is in a shape of a half circle and the general form of a circle with the center at the origin is x2 +y2 = r2?
Answer: [tex]\bold{y = \sqrt{900-x^2}}[/tex]
Step-by-step explanation:
The general form of a circle is: (x - h)² + (y - k)² = r² ; where
(h, k) is the centerr is the radiusSince the roller coaster is centered at the origin, then (h, k) = (0, 0)
Since the height of the roller coaster is 30, then radius (r) = 0
Equation of the circle is: (x - 0)² + (y - k)² = 30²
⇒ x² + y² = 900
To find the equation of the semicircle, solve for "y"
x² + y² = 900
y² = 900 - x²
[tex]\sqrt{y^2}=\sqrt{900-x^2}[/tex]
[tex]y = \pm\sqrt{900-x^2}[/tex]
Since we are looking for the top half of the semicircle (because it is above ground), then use the positive root: [tex]y = \sqrt{900-x^2}[/tex]
Answer:
x^2+y^2=900Step-by-step explanation:
1.Write the equation that models the height of the roller coaster.
x^2+y^2=30^2
2.Start by writing the equation of the circle. (Recall that the general form of a circle with the center at the origin is x2 + y2 = r2. (10 points)
x^2+y^2=900
3.Now solve this equation for y. Remember the roller coaster is above ground, so you are only interested in the positive root. (10 points)
y= √(900-x^2)

Solve this problem in your notebook using all four steps. Harvey is 3 times as old as Jane. The sum of their ages is 48 years. Find the ages of Harvey and Jane. Jane is a0 years old. Harvey is a1 years old.
Answer:
Jane is 12 years old and Harvey's is 36 years old .
Step-by-step explanation:
Given :
Jane is [tex]a_{0}[/tex] years old.
Harvey is [tex]a_{1}[/tex] years old.
Harvey is 3 times as old as Jane.
The sum of their ages is 48 years.
To find : The ages of Harvey and Jane.
Solution :
Jane 's age :
[tex]a_{0}[/tex]
Harvey 's age:
[tex]a_{1}[/tex]
Since we are given that sum of their ages is 48 years
⇒[tex]a_{1} + a_{0} = 48[/tex] ----(A)
We are also given that Harvey is 3 times as old as Jane.
⇒[tex]a_{1} = 3a_{0}[/tex] --- (B)
Solving (A) and (B) using substitution method
Substitute value of [tex]a_{1}[/tex] from (B) in (A) :
⇒[tex] 3a_{0}+ a_{0} = 48[/tex]
⇒[tex] 4a_{0} = 48[/tex]
⇒[tex]a_{0} = \frac{48}{4}[/tex]
⇒[tex]a_{0} = 12[/tex]
Thus , Jane 's age is 12 years .
Substitute this value in (B) to find Harvey,s age :
⇒[tex]a_{1} = 3(12)[/tex]
⇒[tex]a_{1} = 36[/tex]
Thus, Harvey,s age is 36 years .
Hence Jane is 12 years old and Harvey's is 36 years old .
Which graph type would be best for showing the height of a fifth-grade student who is taller than 25% of the other students in his class?
Answer: The bar graph could work.
Answer:
Step-by-step explanation: A box plot takes a large amount of data and clearly identifies the median, first quartile, and third quartile. The first quartile identifies the 25th percentile, and the third quartile identifies the 75th percentile.
To determine how the height of the student compares to 25% of his class, the value of the first quartile of the heights is needed.
Therefore, the best graph type to show how the student compares to 25% of his class is a box plot.

Can somebody help me with this. Please see the attachment.
48
Step-by-step explanation:Let x represent the distance OC. Then CD = x+2, and DP = 16-x. The radius of circle P is ...
... CD +DP = (x+2) +(16-x) = 18
The radius of circle O is ..
... OC + CD = (x) + (x +2) = 2x+2
The length OP is ...
... OC + CP = (x) + (18) = x+18.
Now, the perimeter of ΔAOP is ...
... radius of circle O + radius of circle P + OP = 80
... = (2x+2) + 18 + (x+18) = 3x+38 = 80
Then x is ...
... x = (80 -38)/3 = 14
and the radius of circle O is
... 2x +2 = 2·14 +2 = 30
The desired sum is ...
... OB + BP = (radius of circle O) + (radius of circle P) = 30 + 18
... OB + BP = 48

Phillip bought apples from the grocery for $2.20 per pound. If he had bought 2.5 pounds of apples on Monday and 1.2 pounds of apples on Tuesday, how much did he spend on apples in total?
Answer:
8.14$
Step-by-step explanation:
each pound is for 2.20
2.5 x 2.20 = 5.50$ on Monday
1.2 x 2.20 = 2.64$ on Tuesday
5.50 + 2.64 = 8.14$ in total
Write all of the potential roots of:
p(x) = x^4 − 9x^2 − 4x + 12
So to find the potential roots, we will be using the rational root theorem. The rational root theorem is [tex]\pm \frac{p}{q}[/tex] , with p = factors of the constant and q = factors of the leading coefficient. In this case, our constant is 12 and our leading coefficient is 1:

We don't know anything about the x coordinate of point B other than it cannot be zero (which is what the slash through the equal sign means). You can pick any value you want for x as long as it's not zero. So I'm going to pick x = 1. Point B is located at (x,y) = (1,-7)
Find the slope of the line through A(-5,5) and B(1,-7). Use the slope formula
m = (y2 - y1)/(x2 - x1)
m = (-7-5)/(1 - (-5))
m = (-7-5)/(1 + 5)
m = (-12)/(6)
m = -2
Use this slope value with (x,y) = (-5,5) to find the y intercept b
y = mx+b
y = -2x + b
5 = -2(-5) + b
5 = 10 + b
5-10 = 10+b-10
-5 = b
b = -5
So y = mx+b turns into y = -2x-5 which is the equation of the line through the two points A(-5,5) and B(1,7). The graph is shown below.
note: this answer will be different if you pick a different x coordinate for point B

Every bike at a sports store is on sale for 25% off the regular price. About how much would a bike cost that regularly sells for $145?
Answer:
The bike will cost $108.75
Step-by-step explanation:
In order to find the amount, you must multiply the cost by the percentage being paid. Since the mark down is 25%, you are paying 75% of the overall cost. So multiply 75% by $145.
75% * $145 = $108.75

The perimeter of a rectangle is 26 meters. The difference between the length and the width is 5 meters. Find the width
Why is the answer D? I'm having a hard time with the logic of it.
Let's assume the opposite is the case. So let's assume that a = b is true. If so, then f(a) and f(b) would be the same output. This is because we can replace 'b' with 'a', or vice versa. In other words, f(a) = f(b) would be true. But this contradicts the original inequality that f(b) < f(a)
So that is why 'a' cannot equal b. We don't know if a > b or if a < b (unless we are told if the function is strictly decreasing or increasing on the interval from x = a to x = b), so we just leave it as [tex]a \ne b[/tex]

The zoo has 218 animals in the outdoor exhibits and 454 animals in the indoor exhibits. Estimate how many animals the zoo has by rounding each number to the nearest tenth.
Answer:
670 animals
Step-by-step explanation:
First, round both numbers to the nearest ten. Remember that the numbers 4 and under round down (e.g. 143 = 140) and the numbers 5 and above round up (e.g. 145 = 150).
218 = rounds up = 220
454 = rounds down = 450
Finally, add the rounded numbers together.
220 + 450 = 670
The zoo has approximately 670 animals.
Final answer:
To estimate the total number of animals at the zoo, round the number of animals in the outdoor and indoor exhibits to the nearest tenth and add them together for the estimation. The estimated total number of animals at the zoo is 670
Explanation:
The zoo has 220 animals in the outdoor exhibits and 450 animals in the indoor exhibits.
To estimate the total number of animals, you need to round each number to the nearest tenth:
Round 218 to the nearest tenth: 220
Round 454 to the nearest tenth: 450
By rounding, the estimated total number of animals at the zoo is 670.
Select the correct answer. A moving company charges $115 to rent a truck for a three-day period, plus an additional $0.83 for each mile driven. The average cost per mile for a three-day period is given by the rational expression , where x is the number of miles driven during the rental period. What does the numerator of the rational expression represent?
Answer:The numerator represents the total cost for renting the truck over a three-day period.
Step-by-step explanation:
The numerator of the rational expression represents:
Total cost of the truck when it is rented for a three day period.Step-by-step explanation:x represent the number of miles driven during the rental period.
Also, the fixed charge of the truck when it is rented for a three day period is: $ 115
The charge per mile is: $ 0.83
This means when the car is driven x miles in three day period then the cost is: $ 0.83x
Total cost of the truck in the rental period is: 115+0.83x
This means that the average cost per mile for a three-day period is :
Ratio of total cost of truck to the number of miles driven.
i.e.
[tex]Average\ cos\ per\ mile=\dfrac{115+0.83x}{x}[/tex]
Hence, the numerator represent Total cost of truck during the rental period.
