Answer:
1) , 2) The value of is 3, 3) The perimeter and the area of the rectangule are 18 feet and 18 square feet, respectively.
Step-by-step explanation:
Let be a rectangle with a length of feet and a width of 3 feet. The area (), measured in square feet, and perimeter (), measured in feet, formulas are, respectively:
(Eq. 1)
(Eq. 2)
1) Now, we assume that , then we reduce the system of linear equation into a sole linear equation:
(Eq. 3)
2) We proceed to solve for :
The value of is 3.
3) Lastly, we obtain the values of the perimeter and area:
The perimeter and the area of the rectangule are 18 feet and 18 square feet, respectively.
(1.4 x 10^18) / (1.1 x 10^12) = <u>1.27 x 10^6</u>
Roughly 1.27 million Earth's. That's a bunch.
The answer would be Graph C
Answer:
312
Step-by-step explanation:
Let the attendance before the drop be x
Now we are given that attendance dropped 4% this year
So new attendance =
=
=
We are also given that attendance dropped 4% this year, to 300
So,
Hence the attendance before the drop was 312
