To solve this problem you must apply the proccedure shown below:
1. You have:
Sinα=opposite/hypotenuse
α=62°
opposite=x
hypotenuse=15 ft
2. When you substitute the values into Sinα=opposite/hypotenuse, you obtain:
Sinα=opposite/hypotenuse
Sin(62°)=x/15
3. You must clear "x", as below:
x=(15)(Sin(62°))
x=13.24 ft
The answer is. 13.24 ft
To determine the fourth term, plug 4 into the equation;
5x+25 final answer is x=5
Answer: 5
Step-by-step explanation:
If;
5 gallons = $12.50 / 5 = $2.50/gallon
11 gallons = $26.40 / 11 = $2.40/gallon
In conclusion, 5 gallons cost more per gallon than 11.
