Answer:
Infinitely many solutions
Step-by-step explanation:
By multiplying the entire top equation by two, you'll find that both of these equations are actually technically the same, meaning that there are infinitely many solutions to this system.
Answer:
57.6°
Step-by-step explanation:
It is always helpful to draw a picture. Also, you need to memorize all the definitions of the trig functions. For example,
sine of an angle = opposite side/hypotenuse
In your case, SQ is opposite side to angle R and QR is the hypotenuse
Therefore, sin R = 6.5/7.7
m∠R = arcsin (6.5/7.7) = 57.6°

Answer:
V=785.4
Step-by-step explanation:
V=pi*r^2*h
V=pi*5^2*10
V=pi*25*10
V=pi250
V=785.39=785.4
