Answer:
y = ± 
Step-by-step explanation:
Given
x = a - 2by² ( subtract a from both sides )
x - a = - 2by² ( multiply through by - 1 to clear the leading negative )
a - x = 2by² ( divide both sides by 2b )
= y² ( take the square root of both sides )
y = ± 
First subtract 1.75n-2n-1.25n then you subtract 75 80 and 90 then you divide by n
Answer:
The number of different possible vote totals is 184.
Step-by-step explanation:
It is provided that there are <em>N</em> = 50 people in a club.
The position of President is open. And there are <em>x</em> = 4 members running for he post of President.
So, there are <em>n</em> = <em>N</em> - <em>x</em> = 50 - 4 = 46 people voting for these 4 members.
Each member of the club has <em>x</em> = 4 possible choices.
So, the number of different possible vote totals are:
Number of different possible votes = <em>n</em> × <em>x</em>
= 46 × 4
= 184
Thus, the number of different possible vote totals is 184.
Consider the number 38,288
Now, we have to round this number to the nearest hundreds place.
The place value to the extreme right of the number is ones, then tens, hundreds, thousands, ten thousands and so on.
So, the digit at hundreds place = 2
Consider the digit to the right of the hundred place which is '8', which is greater than 5.
Therefore, we will add '1' to the digit at hundreds place.
Therefore, the number 38,288 rounded to nearest hundreds is 38,300.
3000000...........
10^6 =1000000 (3) = 3000000
