Answer:

Step-by-step explanation:

let number of dimes=x

nickels=x+3

pennies=4x

10 (x)+5(x+3)+4x=110

10 x +5x+15+4x=110

19x=110-15=95

x=95/19=5

dimes=5

nickels=5+3=8

pennies=4*5=20

You need a 30-year, fixed-rate mortgage to buy a new home for $225,000. your bank will lend you the money at an apr of 5.5 perce
bulgar [2K]
Loan amount, P = 225000
interest = 5.5%/12  per month
Monthly payment, A = 1000

At the end of 30 years, 
Future value of loan (with zero repayment)
F1=225000*(1+.055/12)^(30*12)
=1167162.264

Future value of repayment, A=1000 per month
F2=\frac{A((1+i)^n-1)}{i}
=\frac{1000((1+.055/12)^{360}-1)}{.055/12}
=913611.893

Therefore balloon payment
= F1-F2
=1167162.264-913611.893
=253550.37   (to the nearest cent)

What theorem do we use to solve for a side of a right triangle?
melisa1 [442]

Answer:

I would believe you are talking about the Pythagorean Theorem:

In that case the formula is <u>L^2 + L^2 = H^2.</u>

If you have the hypotenuse it is:

<u>H^2 - L^2 = L^2:</u>

When solving, just substitute your lengths for each side of the triangle.

Note: This only works with right triangles.

(4+g)(-11)=121 pls show work whoever has answers first with right answer gets brainliest
Viktor [21]

Answer:

g = -15

Step-by-step explanation:

First, you are going to want to divide by -11 on both sides of the equation.

— (4 + g) (-11) / -11 = 121 / -11

— 4 + g = -11

(Note: dividing a positive number by a negative number will result in a negative number.)

Next, subtract 4 from both sides of the equation.

— 4 + g - 4 = -11 - 4

— g = -15

So, assuming you are looking for the value of g, you're answer is g = -15
