Marie is purchasing a $108,000 home with a 30 year ortgage at 5.25%. What is her monthly principal and interest payment
schepotkina [342]

Answer:

Monthly interest rate is r=0,004375

Monthly principal c=590,625

Step-by-step explanation:

Monthly interest payment rate :

r=\frac{5.25}{12}:100=0,0004375

Now, we need to find monthly principal payment : c=\frac{rP}{1-(1+r)^{-N}}

Use this rule : N=30*12=360

P=108000

r=0,004375

c=\frac{0.004375*108000}{1-(1+0.004375)^{-360}} =\frac{472.5}{0.8}=590,625

How to convert 18 gallons/1 hour to cups and minutes
Ne4ueva [31]
So there are 2 things you need to convert, the first is the gallons to cups and the second is the hours to minutes. so I like to set it up with numerators and denominators and then multiply the ratios. All same terms will cross out and be opposite of each other. 

(18 gal/1 hour) x (1 hour / 60 minutes), now we have (0.3 gallons/1 minute) we just have to change gallons to cups

(0.3 gallons/ 1 minute) x (4 quarts/1 gallon) x (2 pints/1 quart) x (2 cups/1 pint)

this comes out 4.8 cups/1 minute

15 - (-1) = 16
0 / 16 = 0
--------------------------------
You have a slope of 0, meaning that this is a straight horizontal line
