if it has a diameter of 8, that means its radius is half that, or 4.

Answer:
C. 0 6 10
Step-by-Step-Explanation:
the number on the left of the indicated operation is the original set
the number '2' next to R shows that you need to multiply certain numbers by 2
the subscript on the R's shows which row the multiplication needs to be done on...
so in this case, leave the second row alone: 1 3 4
but multiply the first row by 2: 0 6 10
the bag of rice weighs 4.5 pounds
Multiply 4.5 with 16 oz (as 1 lb = 16 oz)
4.5 x 16 = 72.
The bag of rice has 72 oz of rice inside.
The recipe only needs 60 oz of rice ∴ True, you will have enough, with 12 oz left over.
hope this helps
It was $6.00 per pound. So 2 pounds would be $12. But there is still that .6 of a pound left. If we know 1 pound costs $6, then we know 1/10th of a pound will cost $0.60. So 6 x .60 = 3.60. Add 12 and 3.60, and you get 15.60 for 2.6 pounds of granola at the old price.
17.76(5) = 88.15 + 27.52 = 115.67
Answer is A
