Answer:
51
Step-by-step explanation:
tan(z) = 10/8
z = (tan^-1)(1.25)
z = 51.3401917459
Answer:
D
Step-by-step explanation:
3*(-7)=(-21)
There are 4 cups in a quart and 60 seconds in a minute. So 4/120 cups per second or 1/30 cups per second.

Answer: No solutions (system is inconsistent)</h3>
=====================================================
Explanation:
Rearrange the first equation into 
So we have this equivalent system

If you add the terms straight down, then you'll find that the x^2 and y^2 terms add to 0. The right hand side terms add to 16+16 = 32
We are left with the equation 0 = 32, which is a false equation or contradiction. Therefore, there are no solutions. We say the system is inconsistent. The two graphs do not intersect at all as shown in the diagram below. We have two hyperbolas in which the branches extend off to infinity to slowly approach the asymptotes. They never actually get to the asymptotes, but only get closer.
