A jigsaw puzzle contains 50 pieces. If joining any two pieces or groups is considered one move, what is the least amount of moves to join all 50 pieces?

Answers

Answer 1

Answer: So, you see that when 2 pieces is considered a group, that means you have to divide. So, you divide 50/2 and it gives you 25.

Hope this helps :)

Answer:

I don't believe there is an answer to this.

Step-by-step explanation:

How it would usually go is you find the square root of both sides when it is simplified to this point. However, as -9 is negative, it has no square root.

If -9 were positive, however, the square root would be 3 and the question would look like this:

v = 3

Thus, your answer would be 3.

However, they may have given you a way to do this, so this is only what I think based off the experience I have atm.

Answer:

I'm so sorry if I'm wrong, but would it be -3?

Step-by-step explanation:

I'd say its -3 because you would get v by itself, right?

So you square both to get v = -3

Again, srry of I'm wrong!

Cindy made a triangular shaped sculpture with an area of 63 square inches. The height of the sculpture is 9 inches. What is the base length of the sculpture?

Answers

area=base times height times 1/2
63=area
9=height
63=bsae times 9 times 1/2
multiply both sides by 2 to get rid of 1/2
126=base times 9
divide both sides by 9
14=base

base legnth=14 inches

the base is 14 because 14× 9 = 126 and 126÷2 =63
