Answer:
The total cost for 8 skiers=316 dollars
Step-by-step explanation:
Given that the expression 15n+12n+100 represents the total cost in dollars for skis,boots and a lesson for n skiers.
To simplify the given expression :
15n+12n+100=27n+100
27n=-100
Therefore
Now to find the total cost for 8 skiers.
The total cost for 8 skiers can be written as below
Put n=8 in the given expression 15n+12n+100
15(8)+12(8)+100
=120+96+100
=316
Therefore the total cost for 8 skiers is 316 dollars
The total cost for 8 skiers=316 dollars

Answer:
Option (A)
Step-by-step explanation:
It has been given in this question that sign telling path has a 2% grade.
2% grade means a rise of 2 meters for a horizontal change of 100 m (As given in the figure attached).
All the trigonometric ratios for the angle θ between the path and the horizontal are,
Sinθ =
Cosθ =
tanθ =
Since measures of the opposite side and adjacent sides are given
Therefore, tangent ratio will be applied to get the measure of the angle,
tanθ =
θ =
Option (A) will be the answer.
