291.87 is rational since the last (decimal) numbers aren't repeating.
If it was repeating (291.877777...) it would be irrational.

Convert 7 grams into ounces. Round your answer to the nearest hundredth.
Anuta_ua [19.1K]

Answer:

0.25 ounces

Step-by-step explanation:

There are 28.3495 grams in an ounce. So we can create a ratio \frac{28.3495}{1} =\frac{7}{x}. With this we can simplify into x=\frac{7}{28.3495}by multiplying both sides by x and then dividing both sides by 28.3495. This simplified would leave you with 0.25 ounces (rounded to hundredths)

Brainliest would be appreciated!

Ella has 0.5 lbs of sugar. How much water should she add to make the following concentrations? Tell Ella how much syrup she will
AfilCa [17]

I'm guessing the % of syrup refers to the % of sugar it has, therefore:

50% = 50 / 100 = 0.5

0.5 * x = 0.5

x = 0.5/0.5

x = 1

She will have 1 lbs of syrup

A farmer wants to use 200 feet of fencing for a chicken pen. He wants the width of the pen to be 20 feet. What is the length of
Aneli [31]
The length should be 80 feet.

This is because the width is 20, since there are two sides for the width in a pen, we have to add 20+20. This would equal 40. Then we need to subtract 40 from 200. 200-40 would be 160. Then since there are two sides for the length, we need to split that in half. 160÷2 would be 80. To double check, you can do 80+80 and that would still be 160. So the length of one side would be 80. But of course, this whole thing would only be right if the pen has four sides(but since i have seen many chicken pens, there were all rectangular). I hope this helped! :)
