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.
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 ...

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.
Answer:
25%
Step-by-step explanation:
The increase is 4 games and 4x4=16. +4 would be adding 25 percent
X+1=4x-2
+2 +2
x+3=4x
-x -x
3=3x
1=x
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.
