Answer:

Option C) 144 centimeters squared.

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The surface area of a prism is equal to

SA=2B+PL

where

B is the area of the base of the prism

P is the perimeter of the  base

L is the length or height of the prism

<em>Find the area of the base B</em>

B=\frac{1}{2}(3)(4)=6\ cm^2 ---> the base is a right triangle

<em>Find the perimeter of the base P</em>

P=3+4+5=12\ cm ---> is the perimeter of a triangle

we have

L=11\ cm

Find the surface area SA

SA=2(6)+12(11)=144\ cm^2

There is a bag filled with 4 blue, 3 red and 5 green marbles.
bearhunter [10]

Answer:

1/11

Step-by-step explanation

There are 12 marbles in the bag. When we first pick we have 4 blue marbles. So 4 blue marbles/12 random marbles. When we pick blue and noted, there are 3 marbles in the bag because of we didn't put it back. So when we choose again there are 11 marbles and 3 blue marbles in the bag. Choosing a blue one case is 3/11.

The last part of this case is happening as a chain. So we need to multiply our two answers.

=4/12*3/11

=1/3*3/11

=1/11
