(2 spreadsheets, 3 databases and 4 presentations,
As not mentioned other wise equal chances of all the outcomes is assumed so, by the classical definition of probability,
P(The chosen item is a odd numbered database)
=
I don’t know if the answer is rite but imma guess 5
-90
Step-by-step explanation:
2/3x+4=3/5x-2
2/3x – 3/5x = -2 – 4
LCM for 5 & 3 is 15 so we can use it on the two fractions;
10/15x – 9/15x = 1/15 x
1/15x = -6
x = - 6 * 15
x = -90

I believe the answer is
C = 62.83cm
Area of triangle: 1/2(base)(height)
Area of rectangle: length × width
Find the area of the triangles on the sides first using 1/2(base)(height).
Plug 8 for the base and 6 for the height.
1/2(8)(6) = 24 units²
Multiply 24 by 2 for both of the triangles.
(24)(2) = 48 units²
Find the area of the rectangles of the object using length × width.
For the rectangle on top, you can find the width using the Pythagorean Theorem: a² + b² = c².
Plug in 6 and 8 for a and b, and find c (width).
6² + 8² = c²
36 + 64 = 100
Square root both sides; √100 = 10.
The width of the rectangle on top is 10.
Now plug 20 for the length and 10 for the width.
20 × 10 = 200 units²
For the rectangle on the bottom, plug in 20 for the length and 8 for the width.
20 × 8 = 160 units²
For the rectangle on the side, plug in 20 for the length and 6 for the width.
20 × 6 = 120 units²
Add up all the areas ⇒ 48 + 200 + 160 + 120 = 528 units².
