Answer:

$478.06

Step-by-step explanation:

let's first start out by figuring out the present value of the loan

((20540*1.0825)+955+57)-3900

Which gives me a value of 23246.55

I'm then going to assume that the 8.6% is a nominal interest rate meaning that the effectively monthly rate is equal to .086/12=.0072

Which means we have

23246.55=X(a angle 60 at .0072) (i'm using annuities to solve this if you don't know what this is just ask)

Solve this and get $478.06

The ages of three family children can be expressed as consecutive integers. the square of the age of the youngest child is 4 mor
sukhopar [10]
Let the middle child be x
youngest child = x - 1
Oldest child = x + 1

(x - 1)^2 = 8(x + 1) + 4
x^2 - 2x + 1 = 8x + 8 + 4 
x^2 - 10x - 11 = 0
(x - 11) * (x + 1) = 0

X = - 1 makes no sense. How can a middle child be - 1 years old?
x = 11

The youngest child is 10
The middle child is 11
The oldest child is 12

Check
=====
10^2 = 100
(8*12) + 4
96 + 4 = 100 So the results have been checked.

which set of side lengths form a right side?a) 3ft,6ft,5ft b)50 in,48in,14in c)53m,48m,24m d)8cm,17cm,14cm​
muminat

Answer:

<h2>b) 50in, 48in, 14in</h2>

Step-by-step explanation:

If <em>a ≤ b < c</em><em> </em>form of a right side, then <em>a² + b² = c²</em>

a) 3ft, 6ft, 5ft

3² + 5² = 6²

9 + 25 = 36

34 = 36        <em>FALSE</em>

b) 50in, 48in, 14in

14² + 48² = 50²

196 + 2304 = 2500

2500 = 2500     <em>CORRECT :)</em>

c) 53m, 48m, 24m

24² + 48² = 53²

576 + 2304 = 2809

2880 = 2809     <em>FALSE</em>

d) 8cm, 17cm, 14cm

8² + 14² = 17²

64 + 196 = 289

260 = 289    <em>FALSE</em>
