**Answer:**

7.2 times

**Step-by-step explanation:**

There are 36 possible outcomes when rolling a die twice and adding the results. The outcomes for which the sum is 6 are:

Sum = 6: {1,5; 2,4; 3,3; 4,2; 5,1}

**Therefore there is a 5 in 36 chance that the sum will be 6.**

The expected number of trials to achieve that result is given by:

**On average, it would take 7.2 trials to achieve a sum of 6.**

**Answer:**

No puedes simplificar mas esa equation porque no ai nada que la puede reducir

**Step-by-step explanation:**

**Answer:**

500

**Step-by-step explanation:**

Subtract 450 from both sides 25c=12500 so c=500

+2.15.

Explanation: subtract 6.3 by 4.15 = 2.15 so you add 2.15

**Answer:**

The answer is below

**Step-by-step explanation:**

The question is not complete. The complete question is:

The 12 foot long bed of a dump truck loaded with debris must rise an angle of 30 degrees before the debris will spill out. Approximately how high must the front of the bed rise for the debris to spill out.

**Solution: **

Let x be the height of the front of the bed rise needed to be raised for the debris to spill out. We can find x using trigonometric identities. That is:

sin θ = opposite / hypotenuse

Using trigonometric identities, we can get that:

sin(30) = x / 12

This gives:

0.5 = x / 12

Cross multiplying the terms to get:

x = 12 * 0.5

x = 6 ft

Therefore the front of the bed rise must be raised 6 ft for the debris to spill out.
