Answer:
Angle 6 is 47°
Step-by-step explanation:
The average rate of growth of the ice can be found by dividing the thickness by the number of days of growth
The growth rate of the ice over the 8 days is <u>0.375 inches/day</u>
Reason:
The known information on the ice are;
The time it took the ice to reach a thickness of 3 inches = 8 days
Required:
The (average) rate that the ice is growing in c=inches per day
Solution:
Therefore;
The (average) rate of growth of the ice over the 8 days is <u>0.375 inches per day</u>

So the plane of Olivia travels from west to east with an elevation of 6.3 km. To summarize everything and to get the speed of the plane, I used the Angle Side Angle Triangle Theorem and also the law of sine and the formula would be the following:
First is to get the distance traveled by the plane within the range of 3 minutes. To get that distance you must get the following variable.
total distance = distance travel from west to Todds position + distance traveled from Todds position to the reach of the elevation
Dt = D1 + D2
first is getting the D1
D1 = sin41 (6.3) / sin 49
(by following the law of sine and the angles is based on the triangle)
D1 = 5.477 km
then get D2,
D2 = 6.3 sin 65 / sin 25
D2 = 13.510
After that get the total distance
Dt = D1 + D2
Dt = 18.987 km
To get the speed of the plane, you must divide the distance to the time (in minutes) then multiply it by 60 to make it as an hour.
Speed = 18.987 /3 * 60 = 379.74 km/hr
Below are the choices that can be found elsewhere:
