Given:
Cost price of refrigerator = $11515
Discount rate 16% on its marked price.
Profit = 20%
To find:
The marked price of the refrigerator.
Solution:
The cost price (C.P.) is $11515 and the profit percent is 20%. So, the selling price is:
[tex]S.P.=C.P.+20\%\text{ of }C.P.[/tex]
[tex]S.P.=11515+\dfrac{20}{100}(11515)[/tex]
[tex]S.P.=11515+2303[/tex]
[tex]S.P.=13818[/tex]
Let x be the marked price of the refrigerator. Then,
[tex]S.P.=x-16\%\text{ of }x[/tex]
[tex]13818=x-\dfrac{16}{100}x[/tex]
[tex]13818=x-0.16x[/tex]
[tex]13818=0.84x[/tex]
Divide both sides by 0.84.
[tex]\dfrac{13818}{0.84}=x[/tex]
[tex]16450=x[/tex]
Therefore, the marked price of the refrigerator is $16450.

What is the median of 1, 3, 6, 8, 9, 9
Answer choices: A. 6
B. 7
C. 8
D. 9
Answer:
B
Step-by-step explanation:
The median is the middle value of the data arranged in ascending order. If there is no exact middle value then it is the average of the values either side of the middle.
1, 3, 6, 8, 9, 9
↑ middle
median = [tex]\frac{6+8}{2}[/tex] = [tex]\frac{14}{2}[/tex] = 7 → B
Answer:
B. 7

Carl can do a particular job in 4 hours. It takes Mike 7 hours to do the same job. Approximately how long will it take them to do the same job working together?
Answer:
28/11hr or about three hr
Step-by-step explanation
1/4+1/7=11/28
or 28/11 hr
Answer:
2 hours and 32.7 minutes. This is a good problem to become familiar with. It comes up in physics quite frequently.
Step-by-step explanation:
1 job/4 hours + 1 job / 7 hours = 1/x
1/4 + 1/7 = 1/x
(7 + 4)/28 = 1/x
11/28 = 1/x
x / 1 = 28/11
x = 2.54 hours repeating.
1 hour = 60 minutes
0.54 hours = x minutes
1/.54 = 60/x
x = 0.54 * 60
x = 32.7 minutes
Sarah has 35 paperback books and 20 hardback books.
What fraction of the books are hardback
Answer:
4/11...................
Answer: 4/11
Step-by-step explanation:
The total number of books is 35+20=55, which will be the denominator, because the question is asking what fraction of all the books are hardcover. The number of hardcover books, 20, will be the numerator, so we end up with the fraction 20/55. 20 and 55 are both divisible by 5 (this means that when divided by 5, both numbers have a whole number quotient). 20/5= 4 and 55/5=11
So, the answer is 4/11

Frederick's salary varies directly with the hours he works. Last week I earned $ 328.30 and worked 33.5 hours. If he works 35 hours this week, what will be his salary from him?
Answer:
His salary will be of $343.
Step-by-step explanation:
Frederick's salary varies directly with the hours he works.
This means that this question can be solved by proportions, using a rule of three.
We have that:
For 33.5 hours, he earned $328.30. How much he earns for 35 hours?
33.5 hours - $328.30
35 hours - $x
Applying cross multiplication:
[tex]33.5x = 328.30*35[/tex]
[tex]x = \frac{328.30*35}{33.5}[/tex]
[tex]x = 343[/tex]
His salary will be of $343.

A water company charges $20 for service and $2.75 for every thousand gallons of water used in month. Construct a linear model to represent the water bill; how much would you be charged if you used 14-thousand gallons of water this month?
Answer:
$58.50
Step-by-step explanation:
2.75 per 1000
2.75 x 14 = 38.5
$38.50 + $20 =$58.50
Select the correct answer. Every dimension of a triangular pyramid is multiplied by 10 to produce a new figure that is geometrically similar. What effect does this have on the surface area of the pyramid? A. The surface area of the pyramid is multiplied by 10. B. The surface area of the pyramid is multiplied by 50. C. The surface area of the pyramid is multiplied by 100. D. The surface area of the pyramid is multiplied by 1,000. E. The effect on the surface area cannot be determined.
Answer:
C. The surface area of the pyramid is multiplied by 100Step-by-step explanation:
The area is the function of the two dimensions.
If each dimension has changed by 10 times, the the area will change by:

Two mechanics worked on a car. The first mechanic worked for 15 hours, and the second mechanic worked for 5 hours. Together they charged a total of $1725.
What was the rate charged per hour by each mechanic if the sum of the two rates was $195 per hour?
Note that the ALEKS graphing calculator can be used to make computations easier.
х
5
?
First mechanic: $ [per hour
Second mechanic: $ per hour
Answer:
75
120
Step-by-step explanation:
Let the first mechanic's hourly rate = x
Let the second mechanic's hourly rate = y
x + y = 195
15x + 5y = 1725 Divide this equation by 5
3x + y = 345 Write the first equation below this one. Subtract
x + y = 195
2x = 150 Divide by 2
x = 150/2
x = 75
====================
x + y = 195
75 + y = 195
y = 195 - 75
y = 120

it is A square +b square =c square which is just 12×12=144 + 6×6=36 and then add them together which is 180, then just square root 180 can do it for every type of question like that and always remember the longest side is c, and the other two it doesn't matter which is A or B.
Mingfa says, "My sister and I have $130 altogether. If my mother gives me another
$10, I'll have 3 times as much money as my sister."
How much money does Mingfa actually have?
Given:
Total amount of Mingfa and her sister = $130
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
To find:
How much money does Mingfa actually have?
Solution:
Let, Mingfa have $x and her sister has $y initially. Then,
[tex]x+y=130[/tex] ...(i)
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
[tex]x+10=3y[/tex] ...(ii)
Substitute the value of x from (ii) in (i).
[tex](3y-10)+y=130[/tex]
[tex]4y=130+10[/tex]
[tex]4y=140[/tex]
Divide both sides by 4.
[tex]y=35[/tex]
Putting [tex]y=35[/tex] in (i), we get
[tex]x+35=130[/tex]
[tex]x=130-35[/tex]
[tex]x=95[/tex]
Therefore, Mingfa have $95.

Find the zero of the function f(x)=0.8e^2x -9. Round to the nearest hundredth.
Answer: x=1.21
Step-by-step explanation:
Given
Function is [tex]f(x)=0.8e^{2x}-9[/tex]
To find the zeroes, equate the function equal to zero
[tex]\Rightarrow 0.8e^{2x}-9=0\\\\\Rightarrow e^{2x}=\dfrac{9}{0.8}\\\Rightarrow e^{2x}=11.25[/tex]
taking natural logarithm both sides
[tex]\Rightarrow \ln (e^{2x})=\ln (11.25)\\\Rightarrow 2x=2.42\\\Rightarrow x=1.21[/tex]
The zero of the equation is 1.21
