How do i convert 91/10 to a mixed number
geniusboy [140]
The fraction 91/10 is equivalent1 to 9 1/10.
This fraction is a IMPROPER FRACTION once the absolute value of the top number or numerator (91) is greater than the absolute value of the bottom number or denomintor (10). So, the equivalent fraction is a MIXED NUMBER which is made up of a whole number (9) and proper fraction (1/10).
<span>The fraction 91/10 is equal to 91÷10 and can also be expressed in decimal form as 9.1.</span>

May someone help it is just some quick math problems
Anni [7]

Question 1 Answer: 1cm= 3 feet. I say this because if there is 5 cm on the blueprint, you can do 3 feet for every cm and get 15 feet.

Question 2 Answer: 1 in=1.5 feet. 6÷4= 1.5 therefore the scale factor is 1.5

I can't quite see the other answers if you could zoom in i could answer those as well.

A wastewater treatment plant receives 20million gallons per day (mgd) of flow. This wastewater has a solid concentration of 384m
xxMikexx [17]

Answer:

64,092.73 pounds

Step-by-step explanation:

1 gallon = 3.78541 liter

1 pound = 453592 mg

In order to obtain the weight of solids that enter the plant each day, simply multiply the wastewater flow by the solids concentration and make the necessary unit adjustments:

W=20,000,000\ gal*384\frac{mg}{L}*\frac{3.78541\ L}{1\ gal}*\frac{1\ lbs}{453592\ mg} \\W=64,092.73\ lbs

64,092.73 pounds of solids enter the plant each day.
