Answer:
84ways
Step-by-step explanation:
This is a problem on combination. Combination has to do with selection. For example if r objects are to be selected from a pool of n objects, this can be done in nCr ways.
nCr = n!/(n-r)!r!
9C3= 9!/(9-3)!3!
9C3= 9!/(6)!3*2*1
9C3= 9*8*7*6!/(6)!6
9C3= 9*8*7*/6
9C3= 9*8*7*/6
9C3= 504/6
9C3= 84ways

We know that Scott has put 6 rows with 5 stickers each.
The total number of stickers available with Scott = 5*6 = 30 stickers
These 30 stickers are now placed in 5 rows with equal number of stickers in each row.
Number of stickers in each row= Total number of stickers available/number of rows
Number of stickers in each row = 30/5 = 6 stickers
Number of stickers in each row now would be = 6 stickers
Percent of earnings spent on electricity each month is 3.1 %
<em><u>Solution:</u></em>
Given that Ramon earns $1,715 each month and pays $53.40 on electricity
To find: Percent of earnings spent on electricity each month
From given information,
Ramon's monthly salary = $ 1715
Electricity Rent = $ 53.40
<em><u>Finding percentage of earnings spent on electricity:</u></em>
Percent of earnings spent on electricity = 
Substituting the values we get,
Thus Percent of earnings spent on electricity each month is 3.1 %
It actually depdens on which one you set for x and y
let's say that x=number of televisions sold
y=number of copmuter sold
72x+90y=profit
wants to make at least 360
72x+90y≥360
graph
one way is to find the x and y intercepts, first solve for '=' and not '≥'
x intercept, set y=0
72x=360
x=5
x intercept at (5,0)
yintercept
set x=0
90y=360
y=4
yiint at (0,4)
garph the points (5,0) and (0,4) and connect those points with aline
see witch side to graph one
is (0,0) in the solution set?
0≥360
false
it is not
shade on the side that it isn't on
we have
90x+72y≥360
that underline tells us that (0,5) and (4,0) are possible solutions
hmm
see each
the answer is A, if we do x=computers and y=TV, then D is also acceptable
answer is A
