On the maturity date of a $6,600, 9-month, 12% note, the borrower sends a check that includes the principal and all of the interest due on the note. What is the amount of the borrower’s check?

Answers

Answer:

$7194

Step-by-step explanation:

Given the following

Principal = $6600

Time = 9months = 9/12 year

Rate R = 12%

Interest = PRT/100

Interest = 6600*9/12 * 12/100

Interest = 66*9

Interest = $594

Amount on the borrowers check  = principal + interest

Amount on the borrowers check = 6600 + 594

Amount on the borrowers check = $7194

please help lol

Answers

Answer:

Explanation below:

Step-by-step explanation:

To solve this problem you have to look at the three measurements (base x length x height), which are 7in, 3in, and 5in. For the top of the rectangular prism, the surface area is 21in (7in x 3in) and since the bottom is the same, the bottom is also 21in. Now that you have the top and bottom, let's look at the sides. The surface area for the long-sides is 35in (7in x 5in) and since both sides are the same, they are both 35. The surface area for the ends of the rectangular prism is 15in (5in x 3in) and since they are both the same, they are both 15in. Now that you have figured out what measurement goes with what, add all them up. (21in +21in) = 42in | (35in +35in) = 70in | (15in + 15in) = 30in

                                             42in + (70in + 30in)

                                                   42in + 100in

                    The surface area for the entire shape is 142 inches.

How many different ways are there to select a group of 7 out of 9 people for a committee in which there
are 7 distinct roles?

Answers

Answer:

P(9,7) =  181440

Step-by-step explanation:

The roles are distinct so order matters. So we must use the permutation formula.

P(n,r)=n!/(n−r)!

P(9,7) = 9! / 2! = 9*8*7*6*5*4*3 = 181440

Explain how to isolate the variable in this equation -2/5x+7=15

Answers

Answer:

[tex]x = -20[/tex]

Step-by-step explanation:

Use inverse operations and simplification to isolate the variable in the equation.

[tex]-\frac{2}{5}x + 7 = 15\\-7\\\\-\frac{2}{5}x = 8\\[/tex]

Now divide the equation by [tex](-\frac{2}{5})[/tex] remember, dividing a fraction is the same as multiplying by the reciprocal. The reciprocal of a fraction is when one switches the places of the numerator (number on top of a fraction bar), and the denominator (number on the bottom of the fraction bar).

[tex]-\frac{2}{5}x = 8\\[/tex]

÷[tex]-\frac{2}{5}[/tex]

[tex]x = 8 * (-\frac{5}{2})[/tex]

Simplify,

[tex]x = 4 *(- 5)\\\\ x= -20[/tex]
