mrs_skeptik [129]

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

\frac{2}{6}\ of\ the\ lion\ packs\ were\ not\ well\ due\ to\ infection.

10 lions packs were well.

Than the equation becomes for the total number of lion in the zoo be .

\frac{2\times x}{6} + 10 = x

\frac{2x}{6} + 10 = x

simplify the equation

2x + 60 = 6x

6x - 2x = 60

4x = 60

x = \frac{60}{4}

x = 15

Thus the total number of the lion be 15 .

As given

\frac{2}{6}\ of\ the\ lion\ packs\ were\ not\ well\ due\ to\ infection.

Than

Number\ of\ lions\ were\ ill = \frac{2\times 15}{6}

 Number\ of\ lions\ were\ ill = \frac{30}{6}          

                                                     = 5

Therefore the number of lion were ill be 5 .

You stand 50 feet from a monument. The angle of depression from the top of the monument to your feet is 64 degrees. Approximatel
Murrr4er [49]

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.

HACTEHA [7]

Answer:

x = 5

y =  - 5

Step-by-step explanation:

Look at the second equation.

Add 6y to both sides:

- 6x = 6y

Hence,

y =  - x

Substitute this into first equation:

- 4x - x =  - 25

- 5x =  - 25

x = 5

Since y = -x,

y =  - 5
