so it only makes sense to say that the other side of an octagon would be 4 inches too!
But if you want to know the total length, multiply 8 x 4 = 32 inches! BUT THIS IS ONLY IF ITS A REGULAR OCTAGON
otherwise it can't be really determined since I don't know its symmetry or the angles!!
Hope I answered your question! :)
A bag contains 99 red marbles and 99 blue marbles. Taking two marbles out of the bag, you: • put a red marble in the bag if the two marbles you drew are the same color (both red or both blue), and • put a blue marble in the bag if the two marbles you drew are different colors. Repeat this step (reducing the number of marbles in the bag by one each time) until only one marble is left in the bag. What is the color of that marble?
The final marble left in the bag will be red.
Let, analyze the process step by step:
Initially, the bag contains 99 red marbles and 99 blue marbles.
When you take two marbles out of the bag, there are two possibilities: either you get two red marbles or two blue marbles, or you get one red and one blue marble.
a. If you get two marbles of the same color (both red or both blue), you put a red marble in the bag.
b. If you get one red and one blue marble, you put a blue marble in the bag.
After putting a marble back in the bag, you have one less marble in the bag.
You repeat this process, reducing the number of marbles in the bag by one each time, until only one marble is left in the bag.
Now, let's think about the outcomes at each step:
If the bag contains an odd number of marbles (99 red + 99 blue = 198), the final marble will be red because at each step, you are adding a red marble back to the bag.
If the bag contains an even number of marbles (e.g., 100 red + 100 blue = 200), the final marble will be blue because at each step, you are adding a blue marble back to the bag.
In this case, the bag contains 99 red marbles and 99 blue marbles, which is an odd number (198 marbles).
Therefore, the final marble left in the bag will be red.
Connecting a DVD player to a television set requires a cable with special connectors at both ends. You buy a six-foot cable for $15.50 and a three-foot cable for $10.25. Assuming that the cost of a cable is the sum of the cost of the two connectors and the cost of the cable itself, what is the cost of a four-foot cable?
so a 3 foot cable is10.25 a 6foot cable is 15.50 so x=cost per foot y=cost of special connectors 3x+y=10.25 6x+y=15.50 make first equation negative and add to the first 3x=5.25 divide both sides by 3 1.75=x so it costs 1.75 for a foot of cable
subtitue into first equation 3(1.75)+y=10.25 5.25+y=10.25 subtract 5.25 from both sides y=5 dollars=cost of special so 4x+y=4(1.75)+5=7+5=$12
so the cost of a 4 foot cable is $12
when the base of a ladder is placed 10ft away from the base of a building, the top of the ladder touches the building at 18ft above the ground. About how long is ladder?￼￼￼￼
