Answer:
36
Step-by-step explanation:
Use pythagorean theorem
side 1 = 9
side 2 = 12
9^2 + 12^2 = third side ^2
third side = 15
9+12+15 = 36
Hope this helpful!!!!! :)
you have a 1/6 probability of rolling a 6
so for 3 6's it would be
1/6 x 1/6 x 1/6 = 1/216
answer: where is the question?
Answer:
D
Step-by-step explanation:
Parallel lines must have the same slope. They <em>could</em> have points in common. If the y-intercepts were the same, taking into consideration the fact that the slopes have to be the same, it would be the same line and as the question directs, they are not. Parallel lines can have negative slope, as long as their slopes are equal.
Answer:
29
Step-by-step explanation:
Sum of the 21 numbers is 21*30 = 630
Now let's remove 50 from the sum of 630
630-50 = 580
The new average can be found. Remember we removed the largest number so we now have 20 numbers.
580/20 = 29
