Answer:
Tr = 128(1/2)^r
Step-by-step explanation:
After round 1, half of 128 is eliminated = 128/2 = 64
After round 2, half of 64 is eliminated = 64/32 = 32
After round 3, half of 32 is eliminated = 32/2 = 16
After round four, half of 16 is eliminated which is 16/2 = 8
Now, the pattern we have is;
128, 64, 32, 16, 8
The succeeding term keeps decreasing by 2 compared to the preceding term
We can see that this is a geometric pattern with a = 128 and r = 1/2
The nth term is thus
Tn = 128 * (1/2)^n
Thus, the number of teams remaining after r round would be
Tr = 128 * (1/2)^r
Answer:
Step-by-step explanation:
36 = 6* 6 = 2* 3 * 2* 3 = 2*2*3*3
180 = 2 * 2 * 3 * 3 * 5 = 2 * 2 * 3*3*5
Factors that are common will be cancelled
The fourth option because ab = 10 and bc = 10 and ac = 2sqrt(10)
20+ 2Sqrt(10)
answer is the fourth option
10 because
1 quarter = 1/4
so 24 divided by 1/4 = 6
6 + 4 = 10
so john has 10 eggs
hope this helps!!
Say "a" is the length of the first piece, we'll first off, change the mixed fraction to "improper" and add the pieces, keeping in mind that, all 3 pieces add up to 10 feet.
