Best ResponseYou've already chosen the best response.01. Suppose that the amount of algae in a pond doubles every 4 hours. If the pond initially contains 90 pounds of algae, how much algae will be in the pond after 12 hours? (1 point) 720 pounds 360 pounds 1,440 pounds 114 pounds

Best ResponseYou've already chosen the best response.0Alright, this sounds pretty easy! Okay, so, it doubles every hour.

Best ResponseYou've already chosen the best response.0it will double three times since \(12\div 4=3\)

Best ResponseYou've already chosen the best response.0if we start at 90, after 4 hours it will be how much?

Best ResponseYou've already chosen the best response.0Yep! so, then we add 4 more hours to that to make it 8 hours. How much is it now?

Best ResponseYou've already chosen the best response.0Yep! now, lets add a final 4 hours to make it 12. How much is it now?

Best ResponseYou've already chosen the best response.0Yep! So, at 12 hours there will be 720 pounds of algae :) Great job anna!

Best ResponseYou've already chosen the best response.02. What is the order of the numbers from least to greatest? A = 6.2 × 10–5 B = 12.3 × 10–7 C = 5.2 × 103 D = 3.7 × 10–5 (1 point) D < C < A < B B < D < A < C D < C < A < B B < A < C < D

Best ResponseYou've already chosen the best response.0Okay, well first we need to simplify this, and multiply them. After you do this, what do you get?

Best ResponseYou've already chosen the best response.0(Dont forget the order of operations, multiplication comes before subtraction)

Best ResponseYou've already chosen the best response.0So, for A, you would do (6.2 x 10)  5

Best ResponseYou've already chosen the best response.0i cant figure out how to find 5.2x10^3

Best ResponseYou've already chosen the best response.0Okay, well you would do the exponent first (im assuming thats an exponent?) so, you would do 10 x 10 first, which equals 100. then, 100 x 10 which equals 1000. From there, you take 1000 x 5.2 which is?

Best ResponseYou've already chosen the best response.0they are actually all exponents

Best ResponseYou've already chosen the best response.0Oh, can you rewrite them with the ^ like you did the last time to make it for clear? If not, let me know if you have a difficulty and i can explain it :) after we multiply this, it should be very easy to see the smallest number, greatest number, and everything inbetween :)

Best ResponseYou've already chosen the best response.0And yes, 5200 is correct :) Good job!

Best ResponseYou've already chosen the best response.0Okay, that helps, thank you. Well, now we know that C = 5200. Have you done A and B as well?

Best ResponseYou've already chosen the best response.0idk how to do it with negatives

anonymous

Best ResponseYou've already chosen the best response.0Well, there are some rules when multiplying integers. Positive x negative = negative Positive x positive = positive negative x negative = positive negative x positive = negative So, 2 positives makes a positive. 2 negatives makes a positive, and 1 negative makes a negative. I know it probably will be hard to learn, but youll get it eventually :) Practice makes perfect! And dont be afraid to look it up if you need to :)
