Step-by-step explanation:
So i will try to explain it:
Scientists in the past invented this formula and theory of sines:

So the only thing is to put the given numbers into this formula :)
The task that i've just done is like this:

a is the numerator,that is delighted in the triangle,well its transparent.
What about denominator?
Here is the tip:
opposite to A- side angle-a has to be put into sin(a)
sin- how to calculate?
Easy just take the trigonometric functions formula or calculate in scientific calculator that's it.

one of this numbers might be unknown in that case solve by proportion(equation).
Carefully contemplate my answer in the media.
I hope you understood.
Good luck!

Answer: 96 ways
In this case, the freshman must take one class each from Science(6 courses), Humanities(4 courses) and Mathematics( 4 courses).
Then to know how many ways she can arrange you just need to multiply the each course count (it would different if she has to take more than one class).
The calculation would be: 6 x 4 x 4= 96 ways.
Answer:
21
69
Step-by-step explanation:
test 1 = 50
test 2 = 70
70+50 = 120
so tests are .5*120/2 = 30 points
hw = .25*100= 25 points
quiz = .25*75 = 18.75
total score = 30+25+18.75 = 73.75
Answer:
x=7
Step-by-step explanation:
