Answer:

$6750 in the bank account and $20,250 in the stock fund

Step-by-step explanation:

If B is the money they put in the bank and S is the amount they put in the stock fund, then:

B + S = 27000

1.024 B + 1.072 S = 1.06 × 27000

Solving the system of equations:

1.024 (27000 − S) + 1.072 S = 28620

27648 − 1.024 S + 1.072 S = 28620

0.048 S = 972

S = 20250

B = 27000 − S

B = 6750

They should put $6750 in the bank account and $20,250 in the stock fund.

A mole of 1 gallon cans of paint could cover every square inch of the surface of how many planets the size of the earth?

Nady [450]

Answer:

The answer is $4.4*10^1^0 planets$

Step-by-step explanation:

We ll have to find more information first to solve this question.

1. One mole = 6.022 x 10^23

Assuming one gallon of paint covers the 400 sq ft of area.

Thus total area which can be covered by 1 mole of gallon is

$=6.022*10^2^3 * 400\\=2.40*10^2^6$

2. Now we will find the surface area of earth

$Area = 4\pi R^2$

The radius of earth is 2.1 x 10^7 Feet

substituting values

$Area = 4*3.14*(2.1*10^7)^2\\Area = 5.5*10^1^5ft^2$

3. Now we will find out the number of planets of earth size which can be covered by mole of gallon of paint

= Total area one mole of gallon can cover / area of earth

$= 2.40 * 10^2^6/5.5*10^1^5\\=4.4*10^1^0 planets$
