Find the perimeter of the figure to the nearest hundredth.
1 answer:
Answer:
28.87 inch
Step-by-step explanation:
The perimeter of a figure is the sum of the length of the boundary sides of the figure surrounding it.
For the above figure the perimeter is the sum of the three sides of the rectangle and circumference of the semicircle.
Diameter of the semicircle forming in the figure is 5 inch(given)
Circumference of the semicircle forming in the figure =
:

Answer:
6hours
Step-by-step explanation:
From the given information:
Suppose it took Karl x hours to retile her bathroom,
Then it will take Della 3 hours longer i.e (3+x) hours
If Della and Karl work together or will take them 2 hours
The objective is to determine how long it will take Delia to retile the bathroom alone?
∴
By cross multiplying, we have:
2(2x+3) = 3x+x²
4x + 6 = 3x + x²
3x + x² - 4x - 6
x² - x - 6 = 0
Using quadratic equation
x² -3x +2x - 6 = 0
x(x - 3) + 2(x - 3) = 0
(x +2) (x - 3) = 0
x + 2 = 0 or x - 3 = 0
x = -2 or x = 3
Since we are concerned about the positive integer,
Then, Karl = x = 3 hours while Della which is (3+x) = 3+3 = 6hours
