Answer:
42.43 
Step-by-step explanation:
<u>Given</u>:
A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.
Question asked:
What is the area of the shaded region as shown in the figure ?
<u>
Solution:</u>
First of all calculate area of circle and then area of rectangle:-


As here length an width both are 11 cm, we can say that this is a square.

= 
<u>Now, area of shaded region = Area of square - Area of circle</u>
= 121 - 78.571 = 42.429 
Therefore, the area of the shaded region will be 42.43 
Answer:
So, Width = 7/2 or 3.5
Length = 4
Step-by-step explanation:
Area of rectangle = 14 ft^2
Let width of rectangle 2 = x
and Length of rectangle = 2x-3
Formula used for area of rectangle
Area = Length * Width
14 = (2x - 3) x
14 = 2x^2 - 3x
=> 2x^2 -3x -14 = 0
Solving the quadratic equation using factorization
-28 x^2 = -7x * -4x
2x^2 -7x + 4x -14 = 0
x (2x -7) +2(2x-7) = 0
(x+2) (2x-7) =0
=> x + 2 =0 and 2x -7 = 0
x = -2 and x = 7/2
Since width cannot be negative so, x= 7/2
Width= x = 7/2
Length = 2x -3 => 2(7/2) - 3
=> 7 -3
=> 4
So, Width = 7/2 or 3.5
Length = 4.
The <em><u>correct answer</u></em> is:
a strong negative correlation
Explanation:
A strong correlation is one that is close to either 1 or -1. -0.93 is very close to -1, so this is a strong correlation.
A negative correlation is one that has a negative r-value. This is a negative r-value, so it is a negative correlation.
314.16 yards^2 for the Area
If he saves $6 from every $15 he gets, then getting $75 means he saves $30.
Lets says he is paid 15 dollars every hour, and from those he saved 6 dollars. If he earned 72 dollars, that means he is paid 5 times (because 75/15 is 5). So if every time he is paid he saves $6, being paid 5 times means he saves $30 ($6 *5).
