15%=0.15
6000×0.15=900
He paid $900 (15% of $6000; 6000×0.15=900)
$6000-$900= $5100
and he still have to pay $5100
180
This is because 12x5x3 = 180
f(x)=(x+4) ^2 −25
to solve set equal to zero
0 =(x+4) ^2 −25
add 25 to each side
25 = (x+4) ^2
take the square root of each side
square root (25) =(x+4)
+- 5 = (x+4)
5 = x+4 -5 = x+4
subtract 4 from each side
1 =x -9 =x
3.99 = > 3 + 0.99
first let's round up the 0.99, and the 9 rounds up to 1.0 so 0 + 1.0 = 1.
3 + 1 = 4, rounded up.
to the nearest tentth, 4.0.
the .0 simply means 0 tenths, since it's a whole 4.
