Answer:
The bearing is N 55.62° W
Step-by-step explanation:
ship leaves the port of Miami with a bearing of S80°E and a speed of 15 knots.
It then turns 90° towards the south after one hour.
Still maintain the same speed and direction for two hours.
The bearing is just the angle difference from the ship current location to where it started.
Let the speed be km/h
Distance covered in the first round
= 15*1
= 15km
Distance covered in the second round
=15*2
= 30 km
Angle at C = (90-80)+90
Angle at C = 10+90= 100
Let the distance between the port and the ship be c
C²= a² + b² -2abcos
C²= 15²+30²-2(15)(30)cos 100
C²= 225+900+156.28
C²= 1281.28
C= 35.8 km
Using sine formula
30/sin x= 35.8/sin 100
30/35.8 * sin 100 = sinx
0.838*0.9848= sin x
0.8253= sin x
Sin ^-1 0.8253 = x
55.62° = x
The bearing is N 55.62° W
Answer:
B. Fertilizer.
Step-by-step explanation:
In this experiment, you actually failed to include the fertilizer. This is because you are only fertilizing the pumpkins in the sun and not the shade. Therefore, you really do not know if the pumpkins that grew larger and prettier did so because of the fertilizer or the sun. What you should have done was either fertilized all pumpkins, none of the pumpkins, or half of the ones in the sun and half of the ones in the shade. That way you can correctly isolate the effect of the fertilizer on the pumpkins growth.

Answer:
Ok so the answer is 13.7
Step-by-step explanation:
1. x/3 = 74/100
solve the equation above and get 3.7
2. the problem say a 10% tip so add that to 3.7. this equals 13.7
ANSWER: 13.7
Answer:
50²-48²
solve it you will get answer
