Answer: 9-kilogram bag of rice for $29.15</h3>
=============================================================
Explanation:
Calculate the unit rate for the first bag
8 kg = 26.04 dollars
8/8 kg = 26.04/8 dollars ... divide both sides by 8
1 kg = 3.255 dollars
1 kg = 3.26 dollars .... rounding to nearest cent
For the first bag, the unit rate is about 3.26 dollars per kg
---------------
Repeat for the second bag
9 kg = 29.15 dollars
9/9 kg = 29.15/9 dollars ........ divide both sides by 9
1 kg = 3.23888888888889 dollars (approx)
1 kg = 3.24 dollars .... rounding to nearest cent
The unit rate for the second bag is roughly 3.24 dollars per kg
We see that the second bag's unit rate is cheaper by 2 cents, so it is the better deal. This is despite the fact that the entire bag costs more.
3 5/15 is not larger than 3.3385
Answer:
The dimensions of the tire are 190/75-15.
The first number is the width of tire in mm, here is 190 mm
The second number is ratio between sidewall and width of tire in %, here is 75%
The third number is diameter of wheel in inch, here is 15 inch or 15 x 25.4 = 381 mm
Then, we have:
1. The width of the tire is the first number: 190 (mm)
2. The length of the side wall = width x ratio = 190 x 75/100 = 142.5 mm
or 142.5 /25.4 = 5.61 inch
3. The diameter of the whole tire:
D = diameter of wheel + sidewall x 2
= 381 + 142.5 x 2
= 666 mm or 666/25.4 = 26.22 inch
Hope this helps!
