Answer:
Yes they are directly proportional quantities.
Step-by-step explanation:
We find the area of a square by;
A = length squared or (L)² , where 'L' stands for length and 'A' stands for area.
So Area = L²
Assume the length is a units and increase the length by 2 units
The initial area before increasing the length is a²
After increasing the length, the area becomes: (a + 2)² = a² + 4a + 4
Now we subtract the initial area from the final area and get;
(a² + 4a + 4) - a² = 4a + 4
So the new area increases by 4a + 4 units.
Hence, the area increases as the length increases implying that the area of a square is directly proportional to its length.
We denote this proportionality as;
A ∝ L

Basically u are gonna wanna use pythagoras first
BC = √(12^2 - 6^2) = √(144 - 36) = √(108) = 10.39230485
Also the Side Angle Side rule comes into play use the following
BC/sin(55) = CD/sin(90) <----- angle
BC/sin(55) = CD/sin(90)
sin(90)BC/sin(55) = CD
1*BC/sin(55) = CD
BC/sin(55) = CD
10.39230485/0.819152044 = CD
12.68666167 = CD
12.7 = CD
It has been to us that there are a total number of 220 people.
The box plot has been shown to us. We know that in a box plot from the Lower Quartile to the Median the data is 25% of the total amount of data. Likewise, from the Median to the Upper Quartile it is 25% again and from the Upper Quartile to the last data. It is again 25%.
Now, as per the box plot given to us, 6 hours is the Lower Quartile, therefore, more than 6 hours at the computer will have 25%+25%+25%=75% of the total people. The number of total people is 220. Therefore, the number of people who spend more than 6 hours at a computer will be:
75% of 220=
Thus, Option A is the correct option.

Answer:
$11178.20
Step-by-step explanation:
You need to divided the APR/ 12, to know the monthly rate. You have to multiplicate the debt by the monthly rate, the add them. Then substract 471.78 (monthly payment). And repet the procces until the month 36.
You may use an excel sheet to make a table to calculate the payment rmaining.
