425.69+298.72=724.41
29.72+135.47+208.28=373.47
724.41-373.47=350.94
350.94-5=345.94
The answer is c
We shall see how much percentage of the original price was the price discounted and it will show the percentage decreased
325x/100=123.50
325x=12350
X=12350/325
X=38
hope u found this answer helpful
Answer:
-
Step-by-step explanation:
using the half angle formula
cos( ) = ±
cos195° = cos(180 + 15)° = - cos15°
then
cos15° = cos ( ) = = = =
then
cos195° = - cos15° = -
1. 3y
multiplying 3 and y together gets 3y
2. y-5
5 less implies that we subtract 5 from y
3. y+7
adding 7 to y, self-explanatory
4. 9y
same thing as #1
5.
quotient of implies division, since number y is listed first, y is the numerator
It's a COMBINATION where 7 are chosen out of 11
₁₁C₇ = (11!)/(7! , 4!) = 330 combinations
