Step-by-step explanation: If you try to factorize, there are no solutions, and if you use the quadratic formula, you don't get 2 solution for x
Answer:
6.28 km
Step-by-step explanation:
The formula for circumference is C = 2πr. Just plug in the radius. C = 2π2. 2 times 2 is 4. So, multiply 4π, which is 6.283185307 (rounded to the nearest billionths). Generally, you are supposed to round to the nearest hundredth. The 3 would round the 8 down, leaving 6.28. The unit used to measure the radius, so unless told otherwise by the problem, stick to km. This results in 6.28 km being your final answer.
Answer:
The 1/2 liter option ($12.96)
Step-by-step explanation:
Info Given
- Carlos needs 3 liters of milk
- 1/2 liter of milk costs $2.16
- 200 ml container of milk costs 1.17
- 200 ml = 0.2 liters
12.96 = Total of 3 liters of milk with the 1/2 liter amount
17.55 = Total of 3 liters of milk with the 200 ml amount
A. If you divide 6 by 5, you will get 1.2 . So then if you add the 4/15 it will probably be 30 2/3. Because letter C. (31 1/3) seems like too much.
