In this problem, you must use SohCahToa which basically means:
Sin - opposite over hypotenuse
Cosine - adjacent over hypotenuse
Tangent - Opposite over hypotenuse
So in this picture we have 4 -which is on the opposite side of x - and a 5 -which is the hypotenuse of the triangle. This means we must use sin.
Using a calculator you put in:
Your answer is 53.13 degrees
3y=2(2+2y); 3y=4+4y; -y=4; y=-4;
5.24 x 5 = $26.2
5 Muffins would cost $26.2
Well, first, you need to know what you want to 'do' to it.
You want to find the description of what 'x' has to be in order to
make that inequality a true statement. Here's one way to do it:
4/5 x > 14
Multiply each side by 5 : 4 x > 70
Divide each side by 4 : x > 17.5 .
That's it. As long as 'x' is more than 17.5 ,
the original inequality is true.
Answer:
- 670 adult tickets
- 1340 student tickets
Step-by-step explanation:
One group of 2 student and 1 adult tickets will go for 2×$12 +16 = $40. The number of such groups sold was ...
$26,800/$40 = 670
There were 670 adult tickets sold.
There were 670×2 = 1340 student tickets sold.
