Tina went to the store to buy 3 litres of orange juice for a party. the store sold only orange juice in 250ml cartons. how many 250ml cartons did tina need to buy

She needs to buy 12 cartons of 250ml

Step-by-step explanation:

There are 1000ml in a liter, so take 1000/250 t get that we need 4 of the 250ml cartons to have 1 liter. Then, multiply 4 by 3 since she wants 3 liters total, and you get 12 cartons.

Hope this helps

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

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
