Answer:
15, 18, 21
Step-by-step explanation:
3, 6, 9, 12, 15, 18, 21...
3 x 5 = 15
3 x 6 = 18
3 x 7 = 21
Hope this helps! :)
 
        
             
        
        
        
Your answer would be C. 27/190. 
This is because the probability of choosing green as the first marble would be 9/20, as there are 20 marbles in total and 9 of those are green.
The probability of choosing a red marble as the second marble would be 6/19, as no red marbles would have been lost if green was picked first, but there would be one less marble in total.
The 'and' rule for probability, the one that is used to determine the probability of P(A) and P(B), is to multiply, so we need to do 9/20 × 6/19 = 54/380 = 27/190.
I hope this helps!
        
             
        
        
        
7/10 m= 0.7 m
4.1÷0.7=5.85 
You would round down 5.85 to just 5, because he cannot cut less than a whole strip.
To find the exact amount of wire used in 5 strips:
5×0.7= 3.5
4.1-3.5= 0.6 m will be leftover.
        
             
        
        
        
Well, you need a diagram (see attached).
Since angle S = angle T then 
9x -11 = 7x -3  ......  2x = 8 ........ x = 4 
RS = RT = 4
There must be some more information that can't be seen
