Afamily eats at a restaurant. the bill is $42. the family leaves a tip and spends $49.77. a. how much was the tip in dollars? b. how much was the tip as a percentage of the bill?

The tip was 7.77 dollars, which represent 18.5% of the value of the bill

Step-by-step explanation:

Dollars paid as tip

$42 represent 100% of the bill

$7.77 x

x = (7.77/42)*100% = 18.5%

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
