Answer:

A soda costed $3.50.

Step-by-step explanation:

<u>Step 1)</u> We know that a slice of pizza and a soda costs $9 (from Kate's order). With a burger added (Billy's order) it would cost $13.50.

So a burger would cost <em>$4.50</em>:

13.50-9=4.50

<u />

<u>Step 2)</u> We also know a burger and a soda costs $8. So we subtract the cost of the burger from Louis' order to find the cost of the soda:

8-4.50=3.50

Cost of soda: \$3.50

Consider a student loan of $12, 500 at a fixed APR rate of 9% for 25 years.
Eduardwww [97]

The monthly payment is; $104.9; The total amount paid over the term of the loan is; $31470

<h3>How to calculate APR?</h3>

We are given;

Loan principal = $12,500

Interest rate = 12%

Number of payments per year = 12 payments per year.

Loan term = 25 years.

Formula for monthly payment is;

PMT = (p * APR/n)/[1 - (1 + APR/n)^(-nY)]

Where;

p is principal

APR is interest rate

n is number of payments per year

Y is loan term

Thus;

PMT = (12500 * 0.09/12)/[1 - (1 + 0.09/12)^(-12 * 25)]

PMT = 93.75/(1 - 0.106288)

PMT = $104.9

B) Total amount paid over the loan term is;

A = PMT * m * n

where;

m is number of months in a year,

n is number of years

A = 104.9 * 12 * 25

A = $31470

C) The principal as a percentage of the loan is;

P/A = 12500/31470

P/A = 39.72%

Percentage paid for interest is = 100% - 39.72% = 80.28%

What is the value of b for the following circle in general form? x2 + y2 + ax +by+c=0​
liberstina [14]

Answer:

Step-by-step explanation:

<u><em>(1).</em></u> (x - <em>h</em>)² + (y - <em>k</em>)² = <em>r</em>²

where <em>(h, k)</em> are coordinates of a center of the circle with radius <em>r</em>

<u><em>(2).</em></u> ( a ± b )² = a² ± 2ab + b²

~~~~~~~~~~~~~~

( 1 , - 2 ) ; r = 3

( x - 1 )² + ( y + 2 )² = 3²

x² - 2x + 1 + y² + 4y + 4 = 9

x² + y² - 2x + 4y - 4 = 0

a = - 2

b = 4

c = - 4

if a bag contains 2 red marbles, 3 blue marbles, 5 yellow marbles and 2 green marbles, if a marble is randomly selected what is
vekshin1
All you need to do here is just find the ratio of red marbles to all of the marbles.
<u>                    2 red                       </u>
2 red + 3 blue + 5 yellow + 2 green

when you add everything up, you get 2/12, which is equal to 1/6.
