15^2 = x^2 + 11^2
225 = x^2 + 121
Subtract both sides 121
225 - 121 = x^2 + 121 - 121
104 = x^2
x = √104
x = √4 × 26
x = √4 × √26
x = 2 × √26
x = 2 √26

Answer:
$1486.41.
Step-by-step explanation:
Purchase price = $309,900
Down payment percent = 20 %
Remaining amount Percentage = 100-20 = 80%
Mortgage amount = 
=
Formula of monthly payment : 
where P = the payment,
r = the annual rate =6% = 0.06
M = the mortgage amount = $247920
t = the number of years=30
n = the number of payments per year= 12
Substitute the values.
Hence the monthly payment is $1486.41.
Thus Option C is correct.
2(a - b) - (b - a) = 2a - 2b - b + a = 3a - 3b
Answer:
1/4845
Step-by-step explanation:
The probability of selecting a defective cog first is
1/5
The second cog is
3/19
The third cog is
1/9
And the fourth cog is
1/17
Multiplying these together we get
1/5 * 3/19* 1/9 * 1/17 = 1/4845
