Perry Mazza wants to borrow $30,000 from the bank. The interest rate is 6% and the term is for 5 years. What is the amount of in
omeli [17]

Answer: In both the case amount of interest is paid are:

1) $9000

2) $10146.76

Explanation:

Since we have given that

Principle amount = $30000

Interest rate = 6%

Number of years = 5 years

we'll use " Simple interest " first,

As we know the formula for " Simple Interest ":

I=\frac{P\times R\times T}{100}\\\\I=\frac{30000\times 6\times 5}{100}\\\\I=$9000

Now, we'll do it by "Compound Interest "

Amount=P(1+\frac{r}{100})^n\\\\Amount=30000(1+\frac{6}{100})^5\\\\Amount=$40146.76

So,

Interest = Amount-Principle\\\\Interest =40146.76-30000\\\\Interest =\$10146.76

Hence in both the case amount of interest is paid are:

1) $9000

2) $10146.76

A 12-foot ladder is placed 4 feet away from a house as shown.
elena-s [515]

Answer:

Answer:  x = 71 degrees. Yes, the ladder meets safety standards

Discussion:

The problem describes a right triangle with hypotenuse 12, the side against the ground is 4, and the angle between those two sides is "x".  For this triangle,

cosx = (side adjacent to angle) / hypotenuse

      =  4                                      / 12

      =   1/3

To find "x" take the inverse cosine of each side to find that :

x  is approximately 70.52 degrees. That's 71 degrees rounded to the nearest degree.
