Step-by-step explanation:
First find the area of the square ice skating rink: 47^2 = 2209.
Then, find the area of the triangle without ice by using 1/2bh: (12/2)(7)=42.
Simply subtract the triangle's area from the squares for the final answer of 2167 meters squared.
Answer:
Well doesn't it say that the brand has seven sizes, so doesn't that mean that there are 7 available jeans.
Step-by-step explanation:
The formula for the amount A in an account with principal P and interest rate r compounded annually for t years is
... A(t) = P(1+r)^t
You want to find A when P=400, r=0.05, and t=3. Substituting those values gives you
... A(3) = 400·(1 +0.05)³
The appropriate choice is
... A. A(3) = 400·(1 +0.05)³
