3x=40
well first you have to divide 3 by both sides with a result of
x=13.3 repeating
so 13.3333333 to the nearest hundredth would be
x= 13.33

Answer:

m% of n is mn/100.

Step-by-step explanation:

Begin with a concrete example: What is 5% of n?

To answer this, rewrite 5% as 0.05 and multiply n by this 0.05.

Now revert to m% of n: Divide m% by 100% and multiply n by this m/100.

m% of n is mn/100.

Answer:

a) 297°

b) 4.52 minutes

Step-by-step explanation:

a) Consider the attached figure. The boat's actual path will be the sum of its heading vector BA and that of the current, vector AC. The angle of BA north of west has a sine equal to 5/11. That is, the heading direction measured clockwise from north is ...

270° + arcsin(5/11) = 297°

b) The "speed made good" is the boat's speed multiplied by the cosine of the angle between the boat's heading and the boat's actual path. That same value can be computed as the remaining leg of the right triangle with hypotenuse 11 and leg 5.

boat speed = √(11² -5²) = √96 ≈ 9.7980 . . . . miles per hour

Then the travel time will be ...

time = distance/speed

(3900 ft)×(1 mi)/(5280 ft)×(60 min)/(1 h)/(9.7980 mi/h) ≈ 4.523 min
