6 choose 2
6C2 = 6!/(2!(6-2)!)
=6!/(2!4!)
=6•5/2
=15
The answer is 15 ways.
Well, you could tackle the rectangle first; it doesn't really matter what order you go in, as long as you get the final answer.
1) I'll start with the rectangle. Area=base x height, so 10*4=40
2) The top triangle will go next. Area=(base x height) divided by two. 4*10=40
40/2=20
3) Bottom triangle. 3*10=30
30/2=15
4) Add all areas together: 40+20+15=75
The total area is 75cm².
Hope this helps!
Answer:
Answer is 3.398
Step-by-step explanation:
Solve by putting into calculator.
so get the people down to unit rates first
Natalie= 40 in 9 minutes
Steven= 10 in 3 minutes
multiply Stevens to get it even
so by 3
30 in 9 minutes
so Natalie paints faster
