Volume is  area of the triangular part x length.

Area of triangle = 1/2 x base x height  = 1/2 x 6 x 4 = 12 square feet.

Volume = 12 x 8 = 96 cubic feet.

Surface area = area of two triangles ( front and back ) , which we calculates the area of one in Part A, plus the surface area of the two sides plus the area of the bottom:

Area of two triangles = 12 x 2 = 24 square feet.

Area of one side = 5 x 8 = 40 square feet

Area of two sides = 40 x 2 = 80 square feet.

Area of bottom = 6 x 8 = 48 square feet.

Total surface area = 24 + 80 + 48 = 152 square feet.

Pepsi [2]

Answer: 0.00000565

Step-by-step explanation:

Required to win:

6 number match $10,000

5 number match $ 5,000

4 number match $ 1000

3 number match $ 5,00

2 number match $ 50

1 number match $ 10

Therefore, to win $10,000 ;

All 6 numbers must match

Number of right numbers = 6

Total numbers = 25

Since it is without replacement :

Probability = required outcomes / Total possible outcomes

P(First number match) = 6/25

P(second number match) = 5/24

P(third number match) = 4/23

P(fourth number match) = 3/22

P(fifth number match) = 2/21

P(sixth number match) = 1 / 20

Therefore, Probability of winning $10000 :

(6/25) * (5/24) * (4/23) * (3/22) * (2/21) * (1/20) = 720 / 127512000 = 0.0000056465

= 0.00000565

MULTIPLE CHOICE A triangle has an angle that measures 41° and an angle
m_a_m_a [10]

Answer:

117

Step-by-step explanation:

Sum of all the angles of a triangle is 180

Let the third angle be 'x'

41 + 22 + x = 180

     63 + x = 180

             x = 180 - 63

            x = 117
