Answer:
Width of the garden = 22.8 foot
Step-by-step explanation:
Area of the rectangular garden = 2077 square feet.
Let
Width of the garden = x
Length of the garden = 4x
Area of a rectangular garden = length × width
2077 = 4x * x
2077 = 4x²
x² = 2077/4
x² = 519.25
find the square root of both sides
x = √519.25
x = 22.787057730211
To the nearest tenth of a foot.
x = 22.8 foot
Width of the garden = 22.8 foot
Answer:
Option A is correct.
Step-by-step explanation:
The following matrix represent the augmented matrix
In augmented matrix the left side represent the co-efficient of the variables and right side represent the value of variables.
Since the matrix has been solved and reduced so, the solution of variables x, y and z is written on right side of augmented matrix
The given matrix is:
![\left[\begin{array}{cccc}1&0&5&-2\\0&0&3&0\\0&0&0&-1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D1%260%265%26-2%5C%5C0%260%263%260%5C%5C0%260%260%26-1%5Cend%7Barray%7D%5Cright%5D)
Since the last row is all zero and we have a non zero entry for the solution, the matrix is inconsistent.
As the variables have zero values, there cannot be any solution
So, there is no solution.
So, Option A is correct.
The answer is C, because we will divide 30 by 50 and convert it to percentage
Average rate of change over an interval =
(difference in value of the function between the
beginning and end of the interval)
divided by
(length of the interval).
Example:
If the function was 200 pounds at the beginning, and 98 pounds 3 hours later,
then the average rate of change is (98 - 200) / 3 = -34 pounds per hour.
180-70=110 so with the remaining 110 divide by 10 to get x=11
