Answer:
B) 4
Step-by-step explanation:
1. <em>It is either 3 or 4</em>, since those are only two angles comparing the lighthouse and the boat.
2. The angle of depression is noted below the horizontal and above the actual line, and out of 3 and 4, <em>4 is the only angle that is below its corresponding horizontal</em>.
So, the angle of depression from the lighthouse to the boat is 4.
Answer:
7 people, 7 walls, 48 minutes
Each person paints 1 wall in 48 minutes
20 persons, 20 walls
Each person can paint 1 wall in 48 minutes so it will take 48 minutes.
Answer:
96 sqrt(210)
Step-by-step explanation:
6√3 • 8√14 • √10 • √2
We multiply what is outside the square roots with what is outside the square roots and what is inside the square roots with what is inside the square roots
6*8 = 48
3*14*10*2 = 840
6√3 • 8√14 • √10 • √2
48 sqrt(840)
48 sqrt( 4*210)
sqrt(a*b) = sqrt(a) sqrt(b)
48 sqrt(4) sqrt(210)
48 *2 sqrt(210)
96 sqrt(210)
210 is 3*7 *5*2 which are all primes, so we cannot simplify the sqrt (210)
