a car decreased in value from $980 to $720 in one year what was the per cent of decrease to the nearest whole per cent ?

kolezko [41]

The decrease was 27%.

Step-by-step explanation:

Old value = $980

New value = $720

Decrease = Old value - New value

$Decrease=980-720=\$260$

Percent decrease = $\frac{Decreased/ amount}{Old value}*100$

$Percent\ decrease=\frac{260}{980}*100\\Percent\ decrease=0.265*100\\Percent\ decrease= 26.5\%$

Rounding off to near whole percent

Percent decrease = 27%

The decrease was 27%.

What is the Greatest common factor of 18x^2 and 36x

loris [4]

For this case we have that by definition, the Greatest Common Factor or GFC of two or more numbers, is the largest number that divides them without leaving residue.

So:

We look for the factors of 18 and 36:

18: 1,2,3,6,9,18

36: 1, 2,3,4, 6,9,18 ...

Thus, the GFC of both numbers is 18.

Then, the GFC of $18x ^ 2$ and $36x$ is:

$18x$

Answer:

$18x$
