Answer: 4230.14

Step-by-step explanation:

The amount that the balance is multiplied by each month is

$\frac{2448}{2040}=1.2$ .

So, after t months, the balance is $1700(1.2)^{t-1}$ .

Substituting in t=6, we get the balance is

$1700(1.2)^{6-1}=\boxed{4230.14}$ , to the nearest hundredth.

The division of whole numbers is commutative. true or false?

AURORKA [14]

'Commutative' means you can work it in the other direction without changing it.
But 1/2 is not the same number as 2/1 . So I guess division is NOT commutative.

This polygon is composed of a right triangle and a parallelogram.

The area of right angle :
$A_\Delta=\frac{1}{2}\cdot15\cdot8=\frac{1}{2}\cdot120=\boxed{60\ (cm^2)}$

The area of the parallelogram:
$A_P=15\cdot(13-8)=15\cdot5=\boxed{75\ (cm^2)}$

The area of the polygon is equal: $A=A_\Delta+A_P$

Therefore, the answer is:
$\boxed{\boxed{A=60\ cm^2+75\ cm^2=135\ cm^2}}$
