3rd answer

Step-by-step explanation:

Two dice with #s 1-6

To roll a sum of 7, the 2 numbers have to add up to 7.

First die Second die

1 6

2 5

3 4

4 3

5 2

6 1

Each of those combinations adds up to 7. There are 6 of them. The total number of possibilities of rolls is 6 x 6 = 36.

Probability is favorable outcomes / total outcomes, so it's 6/36 = 1/6

Answer:

SSS

Step-by-step explanation:

I can identify that these triangles are congruent by using the SSS (Side, Side, Side) postulate theorem. I know this because first, second, and home triangle share the same side as the third, second, and home triangle, meaning they are congruent, so are the other sides of the angle since the question states they are congruent.

Mario has LaTeX: 2\frac{1}{4}2 1 4 pounds of trail mix. He puts equal amounts of the trail mix into 6 bags for a hike with his f

ioda

Answer:

<h2><em>0.375 pounds </em></h2>

Step-by-step explanation:

Let the amount of trail mix in each bag be x pounds. If Mario has $2\frac{1}{4}$ pounds of trail mix and puts equal amounts of the trail mix into 6 bags for a hike with his friends, the amount of trail mix in each bag can be derives using the expression;

$2\frac{1}{4} = 6 * x$

solving for x

$\dfrac{9}{4} = 6x\\\\2.25 = 6x\\\\divide\ both \ sides \ by \ 6\\\\\dfrac{2.25}{6} = \dfrac{6x}{6} \\\\x = 0.375\\$

<em>Hence 0.375 pounds of trail mix will be in each bag</em>
