Answer:
532 student tickets were sold
Step-by-step explanation:
Let x be the no. of student's tickets sold
Let y be the no. of non student's tickets sold
We are given that 817 tickets were sold in total
So, --1
Cost of 1 student's ticket = $2
So, Cost of x student's ticket = 2x
Cost of 1 non - student's ticket = $3
Cost of y non - student's ticket = 3y
We are given that 817 tickets were sold, for a total of $1919
So, ---2
Solving 1 and 2
Substitute the value of y from 1 in 2
Substitute the value of x in 1
Hence 532 student tickets were sold
Answer:
B
Step-by-step explanation:
You need to find x, so you'll have to use cos in this case, because x is adjacent to the only angle you have.
So, you'll get:
cos 30 = x/10 (adjacent/hypotenuse)
Rearrange the equation for x:
x = cos 30 x 10
<em>*Since the options you have are in exact values, you can't use a calculator just to find x. </em>
Cos 30 in exact values is √3/2
<em>*you can either memorise these values or learn the trig triangles. either way, just know the exact values for sin, cos and tan for 30, 60 and 90 degrees</em>
So to find x:
x = √3/2 x 10
x = 5√3

Your answer is D. You simply plug in the values of each function into the function itself, and then add them together.
f(5)=36, g(-3)=5
36+5=41
