Answer:
Step-by-step explanation:
Let the students price = x
Let the teacher's price = y
34x + 3y = 635
34y = 299.54
y = 299.54 / 34
y = 8.81
The only way to do this is to assume that students and teachers are charged the same amount for admission. But the question should say so.
So x = y
37x = 635.66
x = 635.66 / 37
x = 17.18
So the total spent per student was
8.81 + 17.18 = 25.99
Answer:
40%
Step-by-step explanation:
Tanya has a a choice of 5 different routes (1-20 mins, 2-30 mins, 2-40 mins).
How many routes can she take that will take her 30-mins to get home?
The answer is 2.
What's the probability she will take 2 of the 5 routes to get home?
The probability is 2/5 so 40%.
The rounding instruction was there to mislead you in this case :-)
Answer:
x = 60
Step-by-step explanation:
That square on the angle means 90 degrees so since the other angle is 30 that means x has to be 60

Answer: Choice 2) sin(B) = cos(90-B)</h3>
Explanation:
The rule is that
sin(A) = cos(B)
if and only if A+B = 90.
Solving for A gets A = 90-B
So we end up with
sin(90-B) = cos(B)
which is the same as
cos(B) = sin(90-B)
