Aman bought a computer for 24000 and its accessories pack worth for 1750. He sold it all for *26780. Find his gain and gain per cent.
Answers
Answer:
4%
Step-by-step explanation:
Gain percentage = 1030/25750 x 100 = 4%
Answer:
$1,030, 4%
Step-by-step explanation:
Aman spent $25,750 on a computer and accessory packs (totally worth it). He sold it for $26,780. So let's say Aman is at 0 before he bought this. He spent $25,750, so we subtract that from 0 to get -25,750. Then he sells it all for $26,780 (again totally worth it for the person buying). So we add 26,780 to the total.
-25,750 + 26,780 = 1,030
So Aman made a profit of $1,030 (now he can buy a REASONABLY priced MacBook Air or something)
So to find the percentage that he gained, we divide 1,030 by his original spending price, namely 25,750
1,030/25,750 = 0.04
Convert that to percentage form, you get 4%
Also, it's questions like this that make me question whether the people who write these questions into the textbooks should be talked to lol.

1. given w(x)=4x
a. graph r(x)=4 x w(x). then complete the table of corresponding points on r (x). How do you graph this?
Answers
Answer:
Step-by-step explanation:
a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically stretched by a scale factor of 4.
Table for the corresponding points will be,
x w(x) r(x)
0 0 0×4 = 0
15 60 60×4 = 240
30 120 120×4 = 480
45 180 180×4 = 720
b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).
c). Since, w(x) = 4x
and r(x) = 4[w(x)]
r(x) = 4(4x) = 16x
r(x) = 16x

What is 80% of _____ is 60
Answers
Answer:
75
Step-by-step explanation:
First, we know that 60 is 80 percent of something.
So, on that knowledge, we can setup this equation:
X × 0.80 = 60
Then, we multiply both sides by 0.80 , we then get 75.
We can check with 75 × 0.80 does equal to 60!

Which of the following functions has a maximum value of m, where m is a positive constant?
With explanation please.
Answers
The value of m in the fourth equation does not tend to zero, hence the function that has a maximum value of m, where m is a positive constant is[tex]f(x)=-(m+x)^2[/tex]: Option D is correct.
For any function to have a maximum, the differential of the function must be equal to zero.
If the functions in options A and B and C are differentiated and equated to zero, the values of m in each function will tend to zero as well.
For the function [tex]f(x)=-(m+x)^2[/tex]
[tex]f'(x) = -2(m+x)\times 1\\f'(x)=-2(m+x)\\0 = m+x\\m = -x[/tex]
Since the value of m in the fourth equation does not tend to zero, hence the function that has a maximum value of m, where m is a positive constant is[tex]f(x)=-(m+x)^2[/tex]
