The line represents half of the triangle, so 42/2=21. 21-1=20. The answer is B
Answer:
16
Step-by-step explanation:
Perimeter = distance round the shape
2y + 11 + y + 3 +3y - 2 + 10 = 58
Collect like terms
2y + y + 3y = 58 - 11 - 3 + 2 - 10
6y = 36
y = 36/6
y = 6
Length PQ = 3y - 2 = 3(6) -.2 = 18 - 2 = 16
The pattern is being divided by -2 each time, so the correct answer would be -3
Answer:
the probability is %5.2
Step-by-step explanation:
To know the probability that it is a multiple of 19 we have to know the number of multiples that 19 has between 1 and 1000. And that amount divide it by 1000. Finally we multiply it by 100 and we will have the percentage.
To know how many multiples there are from 1 to 1000 we have to make 1000 divided by 19 and the number that we get the decimals.
1000/19 = 52.63
there are 52 multiples
100*52/1000 = 5.2
the probability is %5.2
