Answer:
10 2/15 hours
Step-by-step explanation:
If we have a candle that is 11 2/5 inches tall
It burns 1 1/8 inches per hour. We need to divide to see how long the candle will last
11 2/5 ÷ 1 1/8
I will convert the mixed numbers to improper fractions
11 2/5 = (5*11+2)/5 = 57/5
1 1/8 = (8*1+1)/8 = 9/8
57/5 ÷ 9/8
Copy dot flip
57/5 * 8/9
456/45
Now we change it back to a mixed number
45 goes into 456 10 times with 6 left over
10 6/45
This simplifies to 10 2/15
Answer:
I'm not sure, but I think they spend 2$ for each
Step-by-step explanation:
The total items they buyed was 45. The total amount of money they spend was 95. 95 divided by 45 is 2.111111111111111111111 . So if you find 2 as one of your options, that's probably it.
Let p be the pre-tax cost. Then 1.08p = $50. Solving for p, the pre-tax cost, we get:
p = ($50) / (1.08) = $46.30.
You can add 5.6 and 5.9 which is 11.5 x 8 = 92 then divide that by 2 and you have 46
