In the US, a pint is 16 fluid ounces and a quart is 2 pints. So, every quart will fill 2 coffee mugs.
Annie needs to fill 26 mugs, and she needs 1 quart for every 2 mugs. So Annie needs 13 quarts of coffee total.
The first and last ones equal .8
I believe they just want you to add here, so for:
a. 12,419,293+100,000
b. 12,419,293+1,000,000
c. 12,419,293- 10,000
the increase is addition and decrease is subtraction. If you're having trouble adding and subtracting them put them over each other and subtract or add them like:
12,419,293
+ 1,000,000

Answer:
The first step to do is trying to find the closest perfect square less than 845, and the closest perfect square more than 845.
In this case 29^2 (841) is the closest perfect square less than 845, and 30^2 (900) is the closet perfect square more than 845.
In conclusion we will say that 29 < √ 845 < 30.
Hope it helps you.
