Jan's old car travelled 198 km in 11 litres of diesel. he brought a new car that could travel twice as far on each litre diesel. how much fuel would jan need to travel 81 km in his new car?

Jan would have to put 4.5 liters of diesel In her new car.

Step-by-step explanation:

to answer this question and show your work you will need to know how to do simple long division and dividing with decimals. If you dont know how to use the decimal, instead of writing a remainder, write a decimal and add a "0" next to your "81" and just continue your division. In the end, you should get 4.5

198 ÷ 11 =18

so 1 liter = 18 km

81 ÷ 18 = 4.5

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

the answer is 99.
