Answer:
490 pounds
Step-by-step explanation:
Peppermint hard candy costs $4.40 per pound, and Cinnamon hard candy costs $5.40 per pound.
If we mix the in x : y ratio respectively then the mixture costs $5.10 per pound.
Therefore, we can write
⇒ 0.3y = 0.7x
⇒
Now, if the candy store has 210 pounds of Peppermint hard candy, then Cinnamon hard candy required for making the mix is pounds. (Answer)
Answer:
[-4,2] or
Step-by-step explanation:
Range is the range of the y-axis.
Although we see that the "line" ends at a specific point, it is neither the highest or lowest y-value.
Our lowest y value is -4, and because it is a line, it is not an open dot resulting in a [, instead of a (.
This same thing happens with highest y-value which happens to be 2.
This is interval notation.
Due to your question, you may be asking for this:
Work=speed times time (my equation to help me figure it out)
ok, 10 men take 84 days to complete a job
therefor, each man completes 1/10 of the job in 84 days
each man does 1/840 of the job per 1 day
so, if we had 5 more, or 15 men
15 times 1/840 times xdays=1 job complete
15/840 times xdays=1job
times both sides by 840/15
xdays=840/15
xdays=56
56 days it would take
