Answer:

2) m∠CBD = 25°

The measure of arc CDB = 230°

4) m arc XY = 10°

The measure of arc WZX = 330°

6) The answer is (c) ⇒ 10 millimeters

Step-by-step explanation:

2) ∵ the measure of arc BC = 130°

∵ Arc BCD is the semi-circle its measure 180°

∴ The measure of arc cd = 180 - 130 = 50°

∵ ∠CBD is inscribed angle subtended by arc CD

∴ m∠CBD = 1/2 measure arc CD

∴ m∠CBD = 50 ÷ 2 = 25°

∵ The measure of the circle is 360°

∵ The measure of arc BC = 130°

∴ The measure of arc CDB = 360 - 130 = 230°

4) ∵ The measure of arc WY = 40°

∵ The measure of arc XZ = 30°

∵ The measure of arc WZ = 60°

∵ m arc WY + m arc XZ - m arc XY = m arc WZ

∴ m arc XY = 40 + 30 - 60

∴ m arc XY = 10°

∵ The measure of the circle is 360°

∴ The measure of arc WZX = 360 - m arc WX

∵ The measure of arc WX = WY - XY = 40 - 10 = 30°

∴ The measure of arc WZX = 360 - 30 = 330°

6) In the circle O

∵ OC ⊥ AB and OX ⊥ ZY

∵ OC = OX

∴ AB = ZY ⇒ Theorem

∵ AB = 10 millimeters

∴ ZY = 10 millimeters ⇒ answer (C)

In physics, Boyle’s law states that if the temperature is constant, then the pressure, P, of a gas is inversely proportional to

VMariaS [17]

The constant of proportionality for this situation is 425

Step-by-step explanation:

When a quantity is inversely proportional with another quantity, then

the product of the two quantities is constant

1. If y is inversely proportional with x

2. Then y ∝ $\frac{1}{x}$

3. that mean y = $\frac{k}{x}$ where k is the constant of variation

4. Then xy = k

∵ In physics, Boyle’s law states that if the temperature is constant

∵ The pressure, P, of a gas is inversely proportional to the volume,

V, of the gas

∴ P ∝ $\frac{1}{V}$

∴ P = $\frac{k}{V}$

∵ The pressure of the gas in a cylinder is equal to 250 kilo pascals

∵ The volume of the container is 1.7 cubic meters

- Substitute these values in the rule of variation to find k

∴ 250 = $\frac{k}{1.7}$

- Multiply both sides by 1.7

∴ k = 425

The constant of proportionality for this situation is 425

What is 10 + v - 17v = 4

rusak2 [61]

Solving for v and combining like terms:
10 + v - 17v = 4
- v - v
10 - 16v = 4
-10 -10
-16v = -6
/-16 /-16
<u><em>v = 0.375 or 3/8
</em></u>Hope this helps!
