Answer:
The area of the pentagon is = 31.5
Step-by-step explanation:
<em>First, we determine the perimeter of the "Pentagon" drawn in the attachment:</em>

<em>Now, we'll check the formula for pentagons:</em>

<em>we calculate the apothem by placing a 90° angle in one of the sides of the shape. It is equal to:</em>
apothem=3
<em>then, we can substitute the values in the formula</em>

You can use the simple interest formula

We need P, which is the primary (or principal) investment, and we know that:
rate = 3% (0.03)
time = 7
i = $25000
So, just plug in and solve:


The company needs to invest $5250 today, to make $25000 in 7 years.
Answer:
Number 1 is 12.
Step-by-step explanation:
{Solve by cross multiplication}
17 • x = 3 • (80 - x)
{Multiply 3 by distribution,}
17x = 240 - 3x
{Add 3x to both sides of the equation,}
20x = 240
{Divide through out by 20,}
20r/20 = 240/20
x = 12
Thus there were 12 pens :)
