<span>What you do is just multiply $56.53 by 1.17. That represents 117% (100% for the meal and 17% for the tip).
Hope that helps! You should get $66.1401, but since you cant have a hundredth of a penny, its just $66.14. :)</span>
Answer:
I think the second one is the answer ; 2√b
Answer:

Step-by-step explanation:
<u>Find the derivative of the function when x=3</u>
<u />





Since the change in the value of the function is
and we know that the change in x is
, then we have:




Therefore, the 2nd option is correct
<u />
The distance: use absolute value
Between x and 8: x-8
The distance between x and 8: | x-8 |
“is no more than” means it can be that or be less than that, so use ≤
The distance between x and 8 is no more than 4
| x-8 | ≤ 4
<span>Amoeba splits 3 times an hour. If Amoeba can split into two every 20 mins then if you divide 60 mins (which would be an hour) by 20 mins (the time they split) you would find that Amoeba can split 3 times in an hour. The question asks how many times it can split in two hours. To find this you have to multiply the 3 times 2. This means that a single Amoeba can split 6 times in two hours. There are 15 Amoeba which means if you take 15 Amoeba time 6 in two hours and 90 would be your answer. There will be 90 Amoeba after the two hours.</span>
