The master family financed a computer that cost $1200. If the interest rate is 19%.how much will the family owe for the computer

Fantom [35]

The answer is $1219

Interest = Total amount * interest rate * time ( I=prt is the formula for calculating interest)

In this case,

Total amount = $1200

Interest rate= $ 0.19

Time span for which interest rate is being calculated= 1/12 (since the rate is yearly and we are calculating interest for a month)

Interest = 1200*0.19*1/12 = 19

So the total amount owned by family at the end of one month = original amount + interest = $1200 + $19 = $1219

Answer:

The area of the shaded region is $(486\pi-648)\ units^{2}$

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the larger circle minus the area of the square plus the area of the smaller circle

Step 1

Find the area of the larger circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=AB=18\ units$

substitute in the formula

$A=\pi (18)^{2}=324\pi\ units^{2}$

step 2

Find the length of each side of square BCDE

we have that

$AB=18\ units$

The diagonal DB is equal to

$DB=(2)18=36\ units$

Let

x------> the length side of the square BCDE

Applying the Pythagoras Theorem

$36^{2}=x^{2} +x^{2}\\ 1,296=2x^{2}\\ 648=x^{2}\\ x=\sqrt{648}\ units$

step 3

Find the area of the square BCDE

The area of the square is

$A=(\sqrt{648})^{2}=648\ units^{2}$

step 4

Find the area of the smaller circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=(\sqrt{648})/2\ units$

substitute in the formula

$A=\pi ((\sqrt{648})/2)^{2}=162\pi\ units^{2}$

step 5

Find the area of the shaded region

$324\pi\ units^{2}-648\ units^{2}+162\pi\ units^{2}=(486\pi-648)\ units^{2}$
