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

Just by looking at the color of a freshly drawn blood sample, how could you distinguish between blood that is well oxygenated an

Wittaler [7]

Answer:

Explanation:

There are two types of blood that flows through our bodies: oxygenated and deoxygenated. Oxygenated blood is the one that is pumped in the left side of the atrium in the heart. As its name tells us, is the one that is highly with oxygen and low in carbon dioxide. Normally a sample of an oxygenated blood will be very bright in red due to the amount of blood cells in it. Deoxygenated blood is the one that is pumped in the right side of the atrium in the heart. This blood is the one that is low in oxygen and high in carbon dioxide. It is also known as the venous blood. Normally a sample of a deoxygenated blood will be darker almost going on blue.

Identify the phases of Meiosis II described below.

Annette [7]

1. The lining up of chromosomes by the spindle fibers takes place at metaphase II phase. It is the second stage of meiosis II, the spindle draws the chromosomes towards the metaphase plate.

2. The formation of the nuclear envelope around each set of DNA takes place in telophase II. Along with the formation of the nuclear envelope, the process of cytokinesis also takes place in telophase II, producing four daughter cells, each comprising a haploid set of chromosomes.

3. The sister chromatids are pulled apart in anaphase II stage. In this phase, the sister chromatids are migrated towards the opposite poles of the cell with the help of protein fibers.

4. The centromeres are moved towards the poles of the cell at prophase II stage.
