The better deal would be the Mini-Cans. If you want to find the value for each of them you first have to decide one value you want them to be in. I chose milliliters. Each liter is equal to 1,000 milliliters. For the liter drinks it means that there is 2,000 milliliters combined. From then you can find the value for each. If you wish to find out the value per milliliter you can simply divide it by 4. The number you get is what each is equal to which is .65. For the next drinks it's the same steps so it would be .852. The best option, the mini cans, is .44. They are the cheapest by around 21 cents less than the liter drinks.
Answer:
a)9:7 b) 9:16 c) 7:16
Step-by-step explanation:
the no of girls (320-180)=140
a) ratio of no of boys and girls=180/140=9/7=9:7
b)ratio of boys and total pupil=180/320=9/16=9:16
c) ratio of the girls and pupils=140/320=7/16=7:16
Step-by-step explanation:
Radius is half of the diameter
Circumference is 2*pi*radius
Area is pi*radius^2
So r (radius)= 10.3
C (circumference)=64.72
and A (area)=333.29
