Keeping in mind that there are 5280 ft in 1 mile, and there are 60 minutes in 1 hr and 60 seconds in 1 minute, therefore 60*60 seconds in 1 hr, or 3600 seconds, then.
Answer:
30 hours
Step-by-step explanation:
We need to convert these to the same period of time
A. 300 minutes
B. 30 hours
30 hours * 60 minutes/ 1 hour = 1800 minutes
C. 0.3 days
.3 days * 24 hours/ 1 day * 60 minutes/ 1 hours =432 minutes
D. 30,000 milliseconds
30 000 ms * 1 seconds/ 1000 ms * 1 minute/60 seconds = .5 minutes
1800 minutes is the longest
Tan^2x + 1 + tanx - 3 = 0 tan^2x + tanx - 2 = 0 (tanx + 2)(tanx - 1) = 0 tanx = -2 or tanx = 1 x = 2.034 radians or x = 5.176 radians or x = pi/4 radians or x = 5pi/4 radians
You have 5 people and 5 seats, so there can't be any empty seats
this means you have to calculate the permutations of 5 objects
5!=5*4*3*2*1=120
1. If two secants intersect to form the vertex of an angle outside a circle and the sides of the angle intercept arcs on the circle, then the measure of the angle is equal to one-half the difference of the measures of the arcs intercepted by the sides of the angle. A prudent auxiliary line is a chord connecting points of intersection of the sides of the angle with the circle as shown at the right.<span>
</span><span>2. Inscribed angle theorem. The measure of an inscribed angle is equal to one-half the measure of its intercepted arc.

According to 2. : measure of arc RT = 2 m (angle S) = 60
Apply 1. : m(angle U) = (arc RS - arc RT )/2 = (84 - 60)/2 = 12
