Answer:
105 snacks
Step-by-step explanation:
$330=45 drinks at $1.50 and x snacks at $2.50.
330=45(1.50)+2.50x
330=67.5+2.5x
2.5x=262.5
x=105 snacks
...more information is clearly needed
The sine of 1/2 the angle = 13 / 32
so this angle = 23.9695 degrees
Therefore the required angle = 2 * 23.9695 = 47.939 to 3 DP's.
If you multiply 9 x 3
=27
And multiplying the 10's means that the exponents need to be added
So the answer would be...
27 x 10^8
