Bottom answer 2/5 and 7/8
One way of doing this would be to look at the πr² as if it were a single term. Then we could divide both sides by πr², which leaves h = V/πr².
Great work! But please show more of the picture
Answer:
$111.59
Step-by-step explanation:
The total amount of the purchase was the cost of the computer plus the sales tax:
$1,257*1,06= $1,332.42
Now, to determine the interest that they will have to pay, you have to consider that the interest rate is 16,75% APR that is the annual percentage rate but as only 6 month have passed, the interest rate at this point that they have to pay is 8.375%:
$1,332.42*8.375%= $111.59
The interest that they will be charged is $111.59
{x+2y+2z=0
{2x+y+z=3
{x-3y-z=1
{x+2y+2z=0
-
{4x+2y+2z=6
{-3x=-6 → x=2
{-3y-z=-1
+
{y+z=-1
{-2y=-2 → y=1
{2+2+2z=0 → 2z=-4 → z=-2
Final triple is
(2; 1; -2)
