Three lots with parallel side boundaries extend from the avenue to the boulevard as shown answer
larisa86 [58]
Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.

Given;
            x + y + z = 140 meters


According to the proportion theorem,

\frac{x}{40} = \frac{y}{30}

Solving for x, using cross multiplication:

\frac{x}{1} = \frac{40y}{30}

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40
z = 7x/8

Now, the third proportions,
y/30 = z/35

Solving for y,

y = 30z/35
y = 6z/7

x + y + z = 140

 4y/3 + 6z/7 +  7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substitutoing z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520
Now,
Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,
We know that
y = 3x/4
so,
y = 40

And,
z = 7x/8
Z = 46.66

In the African savanna, more wildebeests are born than the environment can support. Which is most likely to happen over a period
Maurinko [17]

Answer:

Eventually, the environment will be unable to support the production of wildebeests, this will cause there to be a loss of vegitation that then causes a food shortage, and then the wildebeests will starve.  

Explanation:

It's a very unhappy process, but those herds who don't migrate to another pasture will starve and die. The death will depopulate the savanna and give the fields some time for regrowth and the cycle will begin again.

Hope this helps! :)
