I think 10.24 sq. ft
Vinil7 [7]3 years ago
3 0

Answer: the answer is 10.24

Step-by-step explanation:

you would multiply the Area of a square which is B x H the Area for the square is 0.8 x 0.8 = 0.64

then you multiply the Area of a triangle and the Area of a triangle is B x H divided by 2  and so you multiply the number of triangles there are which is 0.8 x 6 = 4.8 then divide that by 2 which is 2.4 then multiply that with the number of triangles we have all together. there are 4 triangles.

multiply 2.4 x 4 = 9.6 then add the Area of the square which is 0.64 + 9.6 and the answer is 10.24  

hope this helps

statuscvo [17]

Answer:a) 54/55

b) 100/110

c) 99/110

Step-by-step explanation:

a)Probability of ordering 4= 9/12×3/11×2/10×1/9 = 54/11880

Probability of 4 good units= 4 × 54/11880

= 216/11880

1/55

1-(1/55) = 54/55

b)Probability of 2 good units= 2 × 54/(11880)

= 108/11880

= 1/110

1- (1/110)= 100/110

c) Probability of exactly 2 units not good= 1 -(100/110) =99/110
