In the year 2003, a company made $6.8 million in profit. For each consecutive year after that, their profit increased by 13%. Ho
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.

If I have a triangle with a leg of 4 and a leg of 3 what is the length of the hypotenuse
Dmitrij [34]

Answer:

5

Step-by-step explanation:

To solve for hypotenuse we use the Pythagorean theorem:

a^2+b^2=c^2

In this theorem:

c= hypotenuse

a = leg

b = leg

Substitute into theorem:

4^2+3^2=c^2

16+9=c^2

25=c^2

(square root both sides)

5=c

Therefore the hypotenuse has a length of 5.

Please say thanks if correct :)
