LenKa [72]

Answer:

$7.7 million

Step-by-step explanation:

Given: $6.8 million profit made by company.

           13% increase in profit every year.

Now, finding the company´s profit in the year of 2006.

As we know there is 13% increase in profit.

∴ Profit increase= \frac{13}{100} \times 6.8= \$ 0.884

Next adding company´s profit with increase in profit to get profit in the year 2006.

∴ 6.8+0.884= \$ 7.684 ≅ $7.7

The company´s profit in the year 2006 is $7.7 million.

The answer to number 3
Reptile [31]

Answer:

  4.5×10^17 m²

Step-by-step explanation:

The radius is half the diameter, so we can make the substitution r=d/2 into the formula to get ...

  A = 4πr² = 4π(d/2)² = πd²

Filling in the given values and doing the arithmetic gives ...

  A = 3.14×(3.8×10^8 m)² = 45.3416×10^16 m²

  A ≈ 4.5×10^17 m²

__

We round to 2 significant digits because that is the precision of the given diameter.
