Answer:
the meal cost $25.8 in total.
Step-by-step explanation:
9% of 20 is 1.8
20% of 20 is 4
20 + 1.8 + 4 = 25.8
May I have brainliest please? :)
2. Equals 307.629 because if you line up the decimals when you and then you should get your right answer
The given population models for the trees is given as:

It is required to find which forest will have a greater number of trees after 20 years and by how many.
To do this substitute t=20 in the equations of the models:


Hence, forest A has a greater number of trees after 20 years.
Calculate the difference:

It follows that forest A has a greater number of trees than forest B by 43 trees.
After 20 years, forest A has a greater number of trees than forest B by 43 trees.
Answer: The answers are
(i) The slope of segments DE and AC is not 0.
(ii) The coordinates of D and E were found using the Midpoint Formula.
Step-by-step explanation: We can easily see in the proof that the co-ordinates of D and E were found using the mid-point formula, not distance between two points formula. So, this is the first flaw in the Gina's proof.
Also, we see that the slope of line DE and AC, both are same, not equal to 0 but is equal to

which is 0 only if 
So, this is the second mistake.
Thus, the statements that corrects the flaw in Gina's proof are
(i) The slope of segments DE and AC is not 0.
(ii) The coordinates of D and E were found using the Midpoint Formula.
