2 digits number
x <100 because 2digit
x/10 ∈ { 1, 2, 3, 4, 5, 6, 7, 8, 9}
x/3 ∈ {1, 2, 3, 4, 5, 6, 7, 8, 9 }
max number divide by 10 is 90
max number divided by 3 is 99
because we know that numer is divided by 10 so our collections looks like:
{10, 20, 30, 40, 50, 60, 70, 80, 90}
we look from this collections only numbers witch will divided by 3:
30, 60, 90 = this is solutions
a) we need a natural number divided by 3 and 10 lower than 100
b) i need to use lenght of number and what numbers divides them
c) as above
d) baseball, 3 and 10, 3, 30,60,90
Answer: 29 centimeters long
Step-by-step explanation: What you want to do in this kind of situation is to combine all like terms. After, you would get 6x + 24 = 150. What you would do here is to get 6x by itself by subtracting 24 on both sides. Now 6x = 126, to isolate the variable you divide 6 on both sides to get x = 21. However, the questions is asking for the longest side and you know that x + 8 will be the greatest out of all. So, x = 21 + 8 equals 29 centimeters. I hope this helps, please give me a brainlest! :)
The correct answer is it is a figure with at least 3 straight sides. When you think of a square or a triangle they both have at least 3 sides that are straight. A circle doesn't have any straight sides so it is not a polygon.
You can prove that the other answer is wrong because of two things:
The definition of a polygon is a plane figure with at least three straight sides.
Also, when you think of most shapes what do they all have in common? The have at least three straight sides
Answer:
1140 ways.
Step-by-step explanation:
The applicable formula is: (n +r - 1)C(r-1), where n is the number of identical items (the candies), and r is the possible number of recipients (the kids).
The 17 identical candies, can be distributed among the 4 children in :
=(17 + 4 - 1)C(4–1) = 20C3 ways.
= 20!/((20–3)!*3!) ways.
= 20*19*18*17!/(17!*(3*2*1)) = 20*19*18/6 ways
= 20*19*3 ways.
=1140 ways.
