y/9 +5 =0
subtract 5 from each side
y/9 = -5
multiply both sides by 9
y = -5 * 9
y = -45
I believe the answer is 60 students
What i did is that i added the amount of students drama and step which is 61
Then i subtracted 14 because those people liked both hence they would be repeated in the amount of students for drama and step which will be 47
Then i added the 13 students because they werent anywhere in the set which give the answer of 60
If you want the working in terms of sets lmk
Answer:
D
Step-by-step explanation:
Answer:
x = 10 units
Explanation:
First, let's consider the smaller triangle.:
It is a right-angled triangle, therefore, we can use the special trig functions.
tan θ = opposite / adjacent
tan 45 = opposite / 5
opposite = 5
Now, for the larger triangle:
It is also a right angled triangle which means that we can use the special trig functions.
sin θ = opposite / hypotenuse
sin (30) = 5 / x
x = 10 units
Hope this helps :)
The 9-pack is the least per bottle. This is because...
3.79/6 = $0.63 per 1 bottle (6 pack)
4.50/9 = $0.50 per 1 bottle (9 pack)
6.89/12 = $0.57 per 1 bottls (12 pack)
