2 number are x and y
X=10,y=65
Answer:
0.055
Step-by-step explanation:
You want to move the decimal from the % left two places.
Answer:a)117 hours b)4.875days.
Step-by-step explanation:
Using the formula
Speed =Distance / Time
Given Distance = 3 3/5 -mile
and Speed=2/65 miles per hour.
Time =Distance / Speed
Time = (3 3/5)/(2/65)
Time =18/5÷2/65
Time =18/5 x 65/2 =117 hours
Now 24 hours =1 day
therefore 117hours =(117hours x 1 day )/ 24 =4.875days.
Answer:
24

Answer:
<h3>20.6 ft</h3>
Step-by-step explanation:
You must use the trigonometric function.
In this case, it will be tangent.
![tangent=\dfrac{opposite}{adjacent}](https://tex.z-dn.net/?f=tangent%3D%5Cdfrac%7Bopposite%7D%7Badjacent%7D)
We have
![\theta=38^o,\ opposite=r,\ adjacent=20](https://tex.z-dn.net/?f=%5Ctheta%3D38%5Eo%2C%5C%20opposite%3Dr%2C%5C%20adjacent%3D20)
![\tan38^\approx0.7813](https://tex.z-dn.net/?f=%5Ctan38%5E%5Capprox0.7813)
Substitute:
![\tan38^o=\dfrac{r}{20}](https://tex.z-dn.net/?f=%5Ctan38%5Eo%3D%5Cdfrac%7Br%7D%7B20%7D)
<em>multiply both sides by 20</em>
![r=15.626](https://tex.z-dn.net/?f=r%3D15.626)
Tree height is r + 5.
Therefore
![r+5=15.626+5=20.626\approx20.6\ ft](https://tex.z-dn.net/?f=r%2B5%3D15.626%2B5%3D20.626%5Capprox20.6%5C%20ft)
