Answer:
Step by step explanation: OK so your question is 26.35×21.5 so that is pretty easy but if you do not know that you are in the right place so what you’re gonna do is if you have a calculator then you need to take that out if you don’t then I’m going to need a piece of paper now for me it’s easy because I have a calculator and you can find a calculator on your iPad your phone etc. but yeah so you’re gonna type in 26.35 Times 21.5 now I want u do that on your own once you type in those numbers you’re going to hit the = and it’s that simple and you’ll then get your answer so I hope that helped you to learn how you multiply those the numbers.
If it is 2d it is 126
It has 4 sides 2 of them are 12 so add them up and you get 24
And 276-24=252that leaves to more side so divide that 252 by
2 and you get 126
If it is 3d it is 28.5 or 28 1/2
12×4=48
276-48=228
228÷8=28.5 or 28 1/2
I hope I helped if I did Mark me as brainliest
Answer:
Step-by-step explanation:
6 symbols and 4-symbol code so number of combinations wich doesn't contain the same symbol twice would be:
6•5•4•3 = 360
If code starts with a star followed by triangle that means only one posibility for first two symbols and code doesn't containing the same symbol twice means that left 4 symbols for next two.
So number of combinations of code starting with a star followed by triangle and doesn't containing the same symbol twice will be:
1•1•4•3 = 12
The probability that a randomly chosen code starts with a star followed by triangle and doesn't contain the same symbol twice:
