What is that $13,455.78? Something? I did this and got $13,122.76. Here's how I did it:
Use this formula

where A is the ending amount, P is the starting amount, n is the number of times it compounds a year, and t is the number of years. We have all we need to set it up:

First divide and add inside the parenthesis:

then multiply the exponents:

raise the value inside the parenthesis to the power of 260:

and finally multiply to get A = $13,122.76

Answer:
5/11
Step-by-step explanation:
probability = # of favorable outcomes / # of total outcomes
favorable outcome = selecting a pair of formal shoes.
There are 5 pairs of formal shoes so # of favorable outcomes = 5
The total number of outcomes = sum of different pairs of shoes. There are 5 pairs of formal shoes, 2 pairs of traditional shoes, and 4 pairs of casual shoes, so total there are 5 + 2 + 4 = 11 pairs of shoes
so we have probability = # of favorable outcomes / # of total outcomes
and # of favorable outcomes = 5 and total # of outcomes = 11 so probability of selecting a pair of formal shoes is 5/11
Answer:
x=-5.5 y=5.5
Step-by-step explanation:
The elimination or substitution would help.
2y=11
y=11/2
5x+3(11/2)=-11
5x+16.5=-11
-16.5
5x=-27.5
x=-5.5
