Answer:
.3
Step-by-step explanation:
.33 is .03 greater than .3
Work in amount of pure acid let x = gallons of pure acid required.
then we have the equation:-
x + 55(0.6) = 0.80(x + 55)
x + 33 = 0.80x + 44
0.20x = 11
x = 11/0.2 = 55 gallons answer
The perimeter would be about 34.4 because if you choose the bottom side to be ten, by multiplying 35 by 2 to get 70 you can divide by 10 to get 7. Since you know the height and width, you can use pythagorean theorem, a^2 + b^2 = c^2. Plug in the numbers you have 10^2+7^2=c^2. c^2=149, so if you square root 149 you will get a irrational number but when rounded you get 12.2- so that is one side multiply by 2 and get 24.4- and add 10 to get 34.4
Answer:
if the number to the right of the billions place is 5 or more round up if lower than 5 round down
<em>1,</em><em><u>5</u></em><em>00,000,000 round up = 2,000,000,000</em>
<em>1,</em><em><u>4</u></em><em>00,000,000 round down = 1,000,000,000</em>
