I believe you would do 6! which is 6*5*4*3*2*1 to find the number of solutions.

Use the Pythagorean Theorem to find the distance of the missing side. (I’m sorry I need help with the whole thing)

Maurinko [17]

Answer:

1: 5.83

2: 4.12

3: 3.61

4: 5

5: 6.32

6: 5.10

Step-by-step explanation:

The Pythagorean theorem is a^2 + b^2 = c^2

For all of these you can count the number of blocks over to find two sides of the triangle.

For example: the first one has two sides, one is 3 units, the other is 5. To find the missing angle you square 3 and 5, then add that together. That is equal to 34. 34 = c^2. To get the c by itself, you then take the square root of 34. So the missing side (c) is equal to 5.83.

3. Eric filled 3/4 buckets with sand. Then he filled

Sedbober [7]

Answer:

472 3/4

Step-by-step explanation:

Consider the meaning of "one, and one more". That does not mean zero (1-1). Rather, it means two (1+1).

__

Then 3/4 and 472 more is ...

$\dfrac{3}{4}+472=472\frac{3}{4}$

Eric has 472 3/4 buckets filled with sand.

_____

The problem statement here seems to be focused on the filled buckets, rather than the sand stockpile that Eric is working from. The amount in that stockpile is being reduced by the amount that is being used to fill buckets. In short, whether you add or subtract depends on what you're trying to figure.

If 6 is added to x, the result is 17. Find the value of x.

IceJOKER [234]

Answer:

Step-by-step explanation:

To find x, we need to do opposite operations.

x+6=17

Subtract 6 from both sides, since subtraction is the opposite of addition, thus cancelling the 6 out.

x+6=17

-6 -6

x=11

So x is 11.
