Answer
Find out the how many lions were ill .
To prove
Let us assume that the total number of lion in the zoo be x .
As given
10 lions packs were well.
Than the equation becomes for the total number of lion in the zoo be .
simplify the equation
2x + 60 = 6x
6x - 2x = 60
4x = 60
x = 15
Thus the total number of the lion be 15 .
As given
Than
= 5
Therefore the number of lion were ill be 5 .
Answer:
The monument is approximately 86.6 feet tall
Step-by-step explanation:
The given monument parameters are;
The distance of the person from the monument = 50 feet
The angle of depression from the top of the monument to the person's feet = 64°
Given that the angle of elevation to the top of the monument from the person's feet = The angle of depression from the top of the monument to the person's feet, we have;
tan(Angle of depression) = tan(Angle of elevation) = (The height of the monument)/(The distance from the monument)
∴ The height of the monument = tan(Angle of depression) × The distance from the monument
Substituting the known values, gives;
The height of the monument = tan(60°) × 50 ≈ 86.6
The height of the monument ≈ 86.6 feet.
Answer:
8.7
Step-by-step explanation:
20^2-18^2=76
square root of 76 is 8.7 to the nearest tenth
Answer:
Step-by-step explanation:
Look at the second equation.
Add 6y to both sides:
Hence,
Substitute this into first equation:
Since y = -x,
