Answer:
Megan needs a 95 to get an average of 90.
Step-by-step explanation:
Add up the test scores Megan has earlier, you would get 355 as a result of all scores added. In order to get an average of 90%, you would need to accumulate 450 points which she will need to take her final exam on it. Subtract 355 from 450 to get a score of 95% in which she will need that score to average it to 90%.
Answer:
The region with the highest population density is Binky Lee
The region with the lowest population density is Cheslen
Step-by-step explanation:
we know that
The <u><em>population density</em></u> is the number of people per unit of area
so
Find out the population density for each region
<em>Bear Creek</em>

<em>Binky Lee</em>

<em>Cheslen</em>

<em>Crow's Nest</em>

so
Cheslen < Crow's Nest < Bear Creek < Binky Lee
therefore
The region with the highest population density is Binky Lee
The region with the lowest population density is Cheslen
Answer:
(4x + 7y)(4x - 7y)
Step-by-step explanation:
Rewrite 16 as 4^2
= 4^2x^2 - 49y^2
Rewrite 49 as 7^2
= 4^2x^2 - 7^2y^2
Apply the Exponent Rule Pt 1 ((a^m*b^m =(ab)^m))
= (4x)^2 - 7^2y^2
Apply the Exponent Rule Pt 2
= (4x)^2 - (7y)^2
Apply Difference of Squares Formula (( x^2-y^2 = (x + y)(x - y)
= (4x + 7y) (4x - 7y)
The answer would be 7.04^3
