A certain hurricane travels at 20.88 kilometers per hour. The distance from Cuba to Key West is 145 kilometers. Write and solve

anyanavicka [17]

V = 20.88 km / h ( velocity )
d = 145 km ( distance )
Velocity formula: v = d / t
t = d / v ( time )
t = 145 km : 20.88 km/h
t = 6.94444 h
We have to multiply 0.94444 by 60 minutes.
0.94444 · 60 = 56.67 ≈ 56 minutes 40 seconds
Answer: It would take 6 hours 56 minutes and 40 seconds.

What is the value of x?<br><br> A. 4<br><br> B. 4√3<br><br> C. 8<br><br> D. 8√3

SashulF [63]

Answer:

B. 4√3

Step-by-step explanation:

$\sin \: 60 \degree = \frac{x}{8} \\ \\ \therefore \: \frac{ \sqrt{3} }{2} = \frac{x}{8} \\ \\ \therefore \: x = \frac{8 \times \sqrt{3} }{2} \\ \\ \therefore \: x = 4 \times \sqrt{3}\\ \\ \huge \purple{ \boxed{ \therefore \: x = 4 \sqrt{3} }}\\$
