Answer:
$12000 at 5%
$27000 at 6.5%.
Step-by-step explanation:
Let x represent amount invested at 5% and y represent amount invested at 6.5%.
We have been given that a combined total of 39000 is invested in two bonds. We can represent this information in an equation as:

We are also told that the annual interest rate is 2355.00. We can represent this information in an equation as:

Upon substituting equation (1) in equation (2), we will get:







Therefore, an amount of $12,000 is invested at 5%.
Upon substituting
in equation (1), we will get:



Therefore, an amount of $27,000 is invested at 6.5%.
we know that
The sum of the internal angles of a triangle must be equal to
degrees
see the attached figure with letters to better understand the problem
m∠B+
°-----> by supplementary angles
m∠B=
m∠A=
m∠C=
m∠A+m∠B+m∠C=
Substitute

therefore
the answer is
the value of x is equal to 
There's not enough info in this problem to solve it.
Answer:
687
Step-by-step explanation:
First, we want to find the area of the rectangle.
The formula is length times width, so it is 27*280, which equals 7560. We divide this by 11 to get 687.27272727.....(repeating)
The answer is 687.
