Answer:
length = 28 cm
width = 4 cm
Step-by-step explanation:
perimeter = (2 x length) + (2 x width)
perimeter = 64 cm
ratio of length and width = 7 : 1
total ratio of length and width is 8 = a
length = (7/8)a
width = (1/8)a
perimeter = (2 x 7/8)a + (2 x 1/8)a = (14/8)a + (2/8)a = (16/8)a = 2a = 64
a = 64 : 2 = 32 cm
length = 7/8 x 32 = 28 cm
width = 1/8 x 32 = 4 cm
Answer:
$7.92
Step-by-step explanation:
You want to leave a 20% tip on a meal that cost $39.60.
First, convert the 20% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.
Second, you need to find out what 20% of your $39.60 meal cost is.This is always done by multiplying 0.20 by $39.60, or 0.20 x $39.60=$7.92.
So, the amount of tip you are going to leave is $7.92.
