Answer:
the angle of elevation is 12.56°
Step-by-step explanation:
the height of the ramp represents the opposite side and the length of the ramp the hypotenuse
we see that it has (angle, hypotenuse, opposite)
well to start we have to know the relationship between angles, legs and the hypotenuse
a: adjacent
o: opposite
h: hypotenuse
sin α = o/h
cos α= a/h
tan α = o/a
we choose the one with opposite and hypotenuse
sin α = o/h
sin α = 5ft / 23ft
sin α = 5/23
α = sin^-1 ( 5/23)
α = 12.56°
the angle of elevation is 12.56°
Answer:
Silver
Step-by-step explanation:
Find the volume of the coin
<u>Volume of a cylinder</u>
Given:
Substituting given values into the formula to find the volume:
Find the density of the coin given it has a measured mass of 18.54 g
<u>Density formula</u>
where:
= density- m = mass
- V = volume
Given:
- m = 18.54 g
Substituting given values into the density formula:
Given:
Therefore, as 
the coin is made from silver.
Step 1:
Subtract $19 from total
366.50 - 19 = 347.5
Step 2:
Divide this total by the ticket price
347.50 / 34.75 = 10
Step 3:
You have your answer
10 people can go to the amusement park
Answer:
40
Step-by-step explanation:
15/6 = x/16 6x=240 divide 240 by 6 to get 40
