Answer:
0.001953125
Step-by-step explanation:
Divide 34 by 512
34 ÷ 512 = 0.06640625
divide 0.06640625 by 34
0.06640625 ÷ 34 = 0.001953125
Check you work
34 × 0.001953125 = 0.06640625
Answer is 3 4 ÷ 5 12 = 3 4 × 0.001953125
101 = 100 + 1
102 = 100 + 2
103 = 100 + 3
and so on, and
99 = 100 - 1
98 = 100 - 2
97 = 100 - 3
and so on. Then the -th term of the sum, where , is
We want to compute the sum,
We have
but notice that in the last sum, we're just adding the same number of 1s and -1s together, so its value is 0 and
In case you're not familiar with the formula for the sum of consecutive squares, we can derive it here. Recall that
Notice that
and that
Then
Now consider the cases where is either odd or even.
- If is odd, we can write , where . Then
- If is even, we can write and so
The original sum is obtained by adding the odd- and even-indexed sums together:
Answer:
30
Step-by-step explanation:
1) multiply 40 by 75
2) divide by 100
Answer:
712 liters
Step-by-step explanation:
natural:synthetic = 5:8
For every 13 liters of Petrolyn, 8 are synthetic oil. So:
1157/13=89
89 x 8=712 liters of synthetic oil needed ..............
