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%.

The ratio of the width to the the length of a painting is 3 to 7. If the painting is 42in long how wide is it

grandymaker [24]

Answer:

18 inches wide

Step-by-step explanation:

Since the ratio of width to length is 3:7 we can assume that the length will be substancially longer than the width. The length is given as 42 inches long. To find how big the scale factor is, we divide 42 by 7 to get 6. 6 is our scale factor. take 3 x 6 =18 inches wide.

Hope this helps! :)
