Answer:
71°
Step-by-step explanation:
The angle of elevation of the hill can be obtiaed using trigonometry :
Given
the opposite length = 14.5 feets
Adjacent = 5 feets
The angle of elevation vabnbe obtained using :
Tan θ = opposite / Adjacent
Where θ = angle of elevation
Tan θ = 14.5 / 5
Tan θ = 2.9
θ = tan^-1(2.9)
θ = 70.97 = 71°
Answer:
16.225
just times 2.5 times 6.49
B is the correct answer because the bottom should be 8^0 which equals 1
Answer:
He needs to complete a distance of 4,030 yards around the rink to make a total skating distance of 3 miles
Step-by-step explanation:
In this question, we are asked to calculate the number of yards needed to complete 3 miles skating around a rink.
We proceed as follows;
First, we can see he has skated 5 times around a rink that has a distance of 250 yards. His total distance covered would be 250 * 5 = 1250 yards
Now he is looking at completing 3 miles, we need to know the number of yards in 3 miles.
Mathematically, 1 mile = 1760 yards
3 miles = 3 * 1760 = 5,280 yards
To know the number of yards he need to skate more, we simply carry out a subtraction;
5,280 yards - 1250 yards = 4,030 yards
