A jar contains 26 fluid ounces of spagetti sauce.how many cups of spagetti sauce do 4 hard contain?

Answers

4 jars contain 13 cups of spaghetti sauce.

26 fluid ounces * 4 jars

26*4=104
104 fluid ounces in 4 jars
When converting fluid ounces to cups, 1 fluid ounce equals 0.125 cup. So, multiply 104 by 0.125 to get the number of cups.
104*0.125=13
Therefore, 4 jars contain 13 cups of spaghetti sauce.

The first one is 104 ounces and for number two it would be 13 cups
I hope this helps! :D

A town in east Texas received 10 inches of rain in two weeks. If it kept raining at this rate for a 31-day month, how much rain did the town receive?

Answers

If it rained 10 inches in 14 days, then it seems that it rained 10/14 or 5/7 inches of rain per day hypothetical. And since you want to see how many inches it rained in 31 day, multiply 5/7 by 31 and you get about 22.1 inches of rain. Hope this helps.
