What is the perimeter of a hexagon with side of 5 cm?
The hexagon has six sides. So the perimeter will be 6a. a=5cm 6a=6x5 =30 cm
A story problem for 6x5?
Here goes nothing! :) Mary has six cups of flour for her birthday cake. She needs to multiply that amount by five. How many cups of flour does she need in all? Good Luckk!!
What is the GCF of 6x5-8x8?
Take the lowest common power of each variable. In this case, if I understand the question correctly, that's x to the power 5. Separately, take the gcf of the numbers. Multiply everything together.
There are six people in a room each person shakes hands with another person once until they all shake hands fifteen handshakes occur Explain how the fifteen handshakes resulted?
Start out with small cases and you will see the pattern. At that point, you might even guess what the formula is. So let's ay the room has only A and B---two people. there is one handshake (A with B). Three people (A, B, and C), there are three handshakes (A with B and C; B with C). Now, let's try four people (A, B, C, and D), there are six handshakes (A with B, C, and D; B with C and D; C with D). So if we have n+1 people, the number of handshakes is the sum of the first n numbers. This is n(n+1)/2 So for 6 people it is the sum of the first 5 numbers, which is 1+2+3+4+5=15 or 5x6/2=30/2=15 Another way to think of this, if you have done some combinatorics, is for 6 people, in how many ways can you pick two. This is 6C2 or 6x5/2= 15
