The difference between the largest and biggest amount is 7.
Answer:
20% probability
Step-by-step explanation:
First, we need to calculate the area of all the figures inside the rectangle.
Area of triangle= 1/2 BH
So, 3x2=(6)
Area of Square= L^2
3x3=(9)
Area of rectangle= LxW
=60.
60+9+6= 75.
75 is the total area.
Now, lets find the added area of only the triangle and square.
9+6= 15
The probability will be 15/75=
Convert into percent form
= 20%
Hope this helps and please mark me brainliest :)
Answer:
Step-by-step explanation:
- Two triangular ends
- Area of one = 1/2 b * h
- b =1.2
- h =0.9
- Area = 1/2 * 1.2 * 0.9 = 0.54 sq meters
- Area of 2 = 2 * 0.54 1.08
Area bottom
- L = 3.5 m
- w = 1.2
- Area = L * W
- Area = 3.5 * 1.2
- Area = 4.2
Area Back
- L = 3.5
- W = 0.9
- Area = 3.5 * 0.9
- Area = 3.15
Area Slanted piece
- L = 3.5
- w = 1.5
- Area = L * W
- Area = 3.5 * 1.5 = <u> 5.25</u>
Total = 5.25 + 3.15 + 4.2 + 1.08 = 13.68
Answer:
k = 2
Step-by-step explanation:
Given that x = - 1 is a root of the equation, then it satisfies the equation.
Substitute x = - 1 into the equation and solve for k, that is
3(- 1)² - 2k - 2(- 1) - 1 = 0
3 - 2k + 2 - 1 = 0
- 2k + 4 = 0 ( subtract 4 from both sides )
- 2k = - 4 ( divide both sides by - 2 )
k = 2
