Answer:
12 years = 16 USD
15 years = 20 USD
Step-by-step explanation:
15 years =72:4= 18 we round to 20 for 15 years
12 years = 20+20 = 40
72-40 = 32 : 2 = 16 USD for 12 years
Answer:
0.5
Step-by-step explanation:

7/14=0.5
Answer:
Therefore,
93.6 feet tall is the tower from the ground.
Step-by-step explanation:
Given:
x = Opposite side to angle 60
50 ft = Adjacent side to angle 60
7 ft = height of boy
So Height of the tower will be,
![Height\ of\ tower=x+7](https://tex.z-dn.net/?f=Height%5C%20of%5C%20tower%3Dx%2B7)
To Find:
Height of the tower = ?
Solution:
In Right Angle Triangle , Tangent Identity we have,
![\tan 60= \dfrac{\textrm{side opposite to angle 60}}{\textrm{side adjacent to angle 60}}](https://tex.z-dn.net/?f=%5Ctan%2060%3D%20%5Cdfrac%7B%5Ctextrm%7Bside%20opposite%20to%20angle%2060%7D%7D%7B%5Ctextrm%7Bside%20adjacent%20to%20angle%2060%7D%7D)
Substituting the values we get
![1.732= \dfrac{x}{50}\\\\x=86.6\ ft](https://tex.z-dn.net/?f=1.732%3D%20%5Cdfrac%7Bx%7D%7B50%7D%5C%5C%5C%5Cx%3D86.6%5C%20ft)
Substituting "x" For Height of tower we get
![Height\ of\ tower=86.6+7=93.6\ ft](https://tex.z-dn.net/?f=Height%5C%20of%5C%20tower%3D86.6%2B7%3D93.6%5C%20ft)
Therefore,
93.6 feet tall is the tower from the ground.
Answer:
Positive 4
Step-by-step explanation:
I believe this is the same as the problem above.
Factors for 8 => 1, 2, 4, 8
factors for 12 => 1, 2, 3, 4, 6, 12
the common greater number is 4. So the plot will be on posotive 4. Above sea level, which is above zero.
