(b)Newton has bought 12 dozen copies in Rs 4320. His expenditure to bring the copies
to his shop is Rs. 288. How much profit does he make in one copy after selling all
copies in Rs. 5760? Also how much profit in percent did he get in the business of
copy? Find it.
Plz answer
Answer:
He made a profit of 40-32 = Rs 8 per copy.
He got a 25% profit in the business of copies
Step-by-step explanation:
Newton buys and sells copies in his business. He bought 12 dozen = 12*12=144 copies in Rs 4320.
He also has Rs 288 in expenses to bring the copies to his shop, thus the total cost is 4320+288=4608.
Each copy finally cost 4608/144 = Rs 32.
He sold all copies for Rs 5760, at 5760/144= Rs 40 each.
Therefore, he made a profit of 40-32 = Rs 8 per copy.
The total profit in his business of copies was 5760 - 4608= 1152
This is a percentage of:
[tex]\frac{1152}{4608}*100 = 25\%[/tex]

Answer:
4.5
Step-by-step explanation:
when the height is 0 the ball will hit the ground
so the equation is
-12t²+54t=0
12t²-54t=0
2t²-9t=0
t(2t-9)=0
t=0
t=4.5
so the answer is
4.5

Which is an equation of a direct proportion?
Answer:
y=-3x
Step-by-step explanation:
The meaning of direct proportion is that the ratio remains the same, and the ratio will only remain the same if y= a constant number into x
Are there concepts/processes to strictly follow in writing radicals as expressions with rational exponents?
Answer:
The concept or process is [tex]x^{\frac{m}{n}}=(\sqrt[n]{x})^m[/tex].
Step-by-step explanation:
Consider the provided information.
The following property can be used to rewrite each radical as an exponent.
The numerator tells the power of the resulting rational exponent, and the denominator of the rational exponents tells the root of that number.
[tex]x^{\frac{m}{n}}=(\sqrt[n]{x})^m[/tex]
For example:
[tex](27)^{\frac{2}{3}}=(\sqrt[3]{27})^2[/tex]
[tex](27)^{\frac{2}{3}}=(3)^2[/tex]
[tex](27)^{\frac{2}{3}}=9[/tex]
Hence, the concept or process is [tex]x^{\frac{m}{n}}=(\sqrt[n]{x})^m[/tex].

Help me out ( I give out Brainliest)
Answer:
y = 4x -1
I think this is correct
Answer:
y=4x-1
Step-by-step explanation:
What we are doing here is isolating the y variable, and/or solving for y in terms of x. We add y to both sides then subtract 1 from both sides to get y=4x-1. Also, this problem is worded incorrectly and should be worded as 'solve for y in terms of x,' or 'isolate y.'

Answer:
[tex]\huge\boxed{n=5m}[/tex]
[tex]\huge\boxed{55 \ \text{novels}}[/tex]
Step-by-step explanation:
With this word problem, we can model it into an equation which we can interpret to find values.
If we need to read 5 novels per month and n represents the amount of novels read in m months, we know that n will be the dependent variable (y) as it's a direct function of the number of months. This makes m the independent variable (x).
Since there are 5 novels a month, the equation will be 5 times the number of months equals the number of novels per month.
aka - [tex]n=5m[/tex]
We can now substitute inside the equation with 11 months as m, and find the value of n.
[tex]n = 5 \cdot 11[/tex] [tex]n=55[/tex]Hope this helped!
Answer:
The answer is 55
Step-by-step explanation:
Because for every 1 month he reads 5 books
if you do 5 times 11 you get 55
and to check your answer you divide 55 by 5 you get 11
so your equation would be 5 times 11
and your answer would be 55.
hope this helps ;)

Factor the expression 5x + 10
Answer:
5(x+2)
Step-by-step explanation:
When factoring, always use the greatest common factor (GCF) method first. 5x and 10 have a GCF of 5, so this is applicable. Divide each factor by 5:
(5x)/5=x
10/5=2
Now, factor 5 out of 5x+10:
5(x+2)

Answer:
Step-by-step explanation:
25 feet per minute
in 10 minutes
25ft*10=250ft
the diver is 250+200=450
the diver was at 450 below the sea level
Answer:
450 feet below sea level
Step-by-step explanation:
So:
We are looking at 10 minutes ago. If he is being pulled up, that means before he was even more down.
Therefore 25 feet is 1 minute so 10 minutes is 250 feet.
As he was more down below sea level you add 200 feet below sea level with 250 feet below sea level.
This will give you 450 feet below sea level.
I hope this helps!

Help pleaseeeee?????
Answer:
A. 4x-10
Step-by-step explanation:
We see that this is a rectangle. To find the perimeter, we do L+W+L+W. So in this case, we can do (x+2)+(x-7)+(x+2)+(x-7). We can also simplify this to 2(x+2)+2(x-7)
Combine like terms now.
Simplify this to:
2x+4+2x-14
Simplify further:
4x-10
Answer:
4x-10
Step-by-step explanation:
The perimeter is the total around a shape. That means there will be two copies of each equation.
2(x+2)= 2x+4
2(x-7)= 2x-14
Add the two equations together and simplify.
2x+4+2x-14=
Add the like terms 2x together.
2x+2x= 4x
Keep doing the problem
4x+4-14
Solve 4-14 which equals -10
4x-10
