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

Hyperpolarization means that the ________. Group of answer choices membrane potential becomes more negative than the resting pot

gladu [14]

Answer:

Hyperpolarization means that the membrane potential becomes more negative than the resting potential.

Explanation:

The voltage across the membrane of a neuron that is at rest and not sending out signals is called the resting membrane potential, or just the resting potential. The concentration gradients of ions across the membrane and the amount of each type of ion that can pass through the membrane determine the resting potential. When a neuron is at rest, there are different levels of sodium and potassium on both sides of the cell membrane. Ions move down their gradients through channels. This creates a difference in charge, which gives rise to the resting potential.

When the membrane potential at a particular location on the neuron's membrane gets more negative, this phenomenon is known as hyperpolarization. Depolarization, on the other hand, occurs when the membrane potential becomes less negative (more positive). Both depolarization and hyperpolarization can take place as a result of the opening and closing of ion channels in the membrane, which changes the rate at which certain types of ions can enter or leave the cell.
