Answer:
Original price was $2163
Step-by-step explanation:
Let original price be x
23% of x = 497.42
23/100 × x = 497.42
23x/100=497.42/1
Cross multipy,
23x × 1 = 497.42 × 100
23x=49742
x=49742/23
x=2,163 approximately
Given:
The equation is:
To find:
The number that should be added to sides of the equation to complete the square.
Solution:
If an expression is in the form of , then we have to add to make it perfect square.
We have,
...(i)
To make it perfect square we need to add square of half of coefficient of x on both sides.
Coefficient of x is -10, so square of half of coefficient of x is:
On adding 25 on both sides of (i), we get
Therefore, we need to add 25 to both sides of the equation to complete the square.
Answer:
rational
Step-by-step explanation:
6 can be cut in haft.
400+575+575+670+720+885+1250=5075
5075/7=725
Mean = 725
400, 575, 575, 670, 720, 885, 1250
Median = 670
725>670
C) The Mean is greater than the Median
