Answer:

correct option is B. about 30 years

Explanation:

given data

real per capita GDP west = $10,000

annual growth rate = 2.33%

real per capita GDP east = $2,500

annual growth rate = 7%

to find out

How many years will it take for East to catch up GDP of West

solution

we know here that future value is equal to real GDP of west after time will be

future value = real per capita GDP west × $rate^{t}$

future value = 10000 × $(1+0.0233)^{t}$ .....1

and

future value = real per capita GDP east × $rate^{t}$

future value = 2500 × $(1+0.07)^{t}$ .....2

compare equation 1 and 2

10000 × $(1+0.0233)^{t}$ = 2500 × $(1+0.07)^{t}$

4 $(1.0233)^{t}$ = $(1.07)^{t}$

t = about 30 years

so correct option is B. about 30 years

Which of the following could a typical third grader handle?

N76 [4]

10-15 push ups: it's because pull-ups are taxing for an 8 year old, using my brother for an example who can hardly lift himself up. Sit-ups are taxing on the back due to the amount of muscular endurance and strength while a mile running-I laugh- converted to meters is approximately 1609 meters. I'm in Junior high yet I can only do 900. Thus, it can be concluded the most appropriate activity a third grader could handle is a simple push-up.

Estimate the liquid density (g/cm3) of propane at 298 K and 10 bar. Compare the price per kilogram of propane to the price of re

Deffense [45]

Answer:

Density of propane = 17.8 g/L

Propane is more priced than gasoline

Explanation:

Given:

Temperature, T = 298 K

Pressure, P = 10 bar = 0.987 × 10 = 9.87 atm

now,

Molar mass of propane, M = 44.1 g/mol

From ideal gas law

⇒ PV = nRT

here,

n is the number of moles

R is the ideal gas constant = 0.0821 L.atm/mol.K

also,

Density, D = $\frac{\textup{Mass}}{\textup{Volume(V)}}$

or

V = $\frac{\textup{Mass}}{\textup{D}}$

and,

nM = mass

thus,

V = $\frac{\textup{nM}}{\textup{D}}$

substituting in the ideal gas relation

we have

P = $\frac{\textup{DRT}}{\textup{M}}$

or

D = $\frac{\textup{PM}}{\textup{RT}}$

or

D = $\frac{9.87\times44.1}{0.0821\times298}$

or

D = 17.8 g/L

Now,

1 gallon = 3.78 Liter

Therefore,

5 gallon = 5 × 3.78 Liter = 18.9 Liter

Thus,

mass of 5 gallon propane = Volume × Density

= 18.9 Liter × 17.8 g/L

= 336.42 g

or

= 0.336 kg

also it is given that Price of 5 gallon propane i.e 0.336 kg = $30

Therefore,

Price per kg = $\frac{30}{0.336}$

= $89.28

and,

Mass of 5 gallons i.e 18.9 Liter gasoline = Density × Volume

= 0.692 g/cm³ × 18.9 Liter

also,

1 L = 1000 cm³

thus,

= 0.692 g/cm³ × 18.9 × 1000 cm³

= 13078.8 g

or

= 13.078 kg

Therefore,

Price per kg of gasoline = $\frac{\$30}{13.078}$

= $2.29

hence, propane is more priced than gasoline

Which of the following statements is true about the constant growth model?

Eduardwww [97]

Answer: The constant growth model can be used if a stock's expected constant growth rate is less than its required return.

Explanation:

The Constant Growth Model is a stock valuation method.

It assumes that a company's dividends are increasing at a constant growth rate indefinitely.

Formula: Current price = (Next dividend the company is to pay) ÷ (required rate of return for the company - expected growth rate in the dividend.

When expected constant < required return, then the constant growth model can be used.

Hence, the statement is true about the constant growth model :

The constant growth model can be used if a stock's expected constant growth rate is less than its required return.
