Dvinal [7]

Answer:

The recycle percent as a rate per 100 is 0.03 per hour.

And 12 dolls are recycled each hour during production.

Step-by-step explanation:

The question is incomplete so below is the complete question:

A factory produces toy dolls at a rate of 400 per hour and has to recycle 3% of them because the clothes are torn. Express the recycle percent as a rate per 100. How many dolls are recycled each hour during production?

Now, to express the recycle percent as a rate per 100, And to find the number of dolls are recycled each hour during production.

Number of dolls factory produces at rate per hour = 400.

Percent of recycle = 3%.

So, to express the recycle percent as a rate per 100:

$3\%\ per\ 100$

$=\frac{3}{100} \ per\ hour$

$=0.03\ per\ hour.$

So, to get the number of dolls are recycled each hour during production:

3% of number of dolls factory produces at rate per hour.

$=\frac{3}{100} \times 400$

$=0.03\times 400$

$=12.$

The dolls are recycled each hour = 12.

Therefore, the recycle percent as a rate per 100 is 0.03 per hour.

And 12 dolls are recycled each hour during production.

Emily has $100 extra to spend on supplies for her T-shirt-making business.

iris [78.8K]

Answer:

B. 5i + 12b < 100

Step-by-step explanation:

I used process of elimination on to figure this one out.

I first eliminated A because I knew the i should be next to the 5. I know this because i (ink) costs 5 dollars each.

I next eliminated D because this equation is looking to find the sum of the ink and the new brushes, not the ink plus the total cost equaling the brushes.

Finally, I eliminated C because Emily only has $100, so the cost of the ink (i) and the brushes (b) must NOT excede 100 dollars. From this, I can see that C states that the sum exceeds Emily’s $100 budget

This leaves us with B as the final answer

Hope this helps! Have a lovely rest of your day!
