She can put 36 because nCr is 9C7, so according to find different permutation.
Answer:
$99
Step-by-step explanation:
MP3 Player: $100
10% Mark up: $100/10= 10
Therefore, Mark-Up Price: $100+$10= $110
This was then Marked down by 10%.
Therefore,
10% Marked down: $110/10= $11
(We then take this away from the marked up price)
Hence, Final Price : $110-$11= $99
Answer:
7:3 would be the fully simplified ratio.
Hope this helps! :)
Answer:
the minimum value of y is -324
Step-by-step explanation:
Add the square of half the g coefficient:
g^2 -2g +1 = y +324
(g -1)^2 -324 = y
This is "vertex form" indicating the vertex is (1, -324). The leading coefficient is positive, so the parabola opens upward. The vertex is the minimum.
Minimum y-value is -324.
I dont understand wouldn't twice the number of 9 be 18 or 11?
9+2=11 or 9×2=18
