Answer:
1.21 * 10^25.
Step-by-step explanation:
11 *10^11 * 12 * 10^2
= 11*12 * 10^11 * 10^12
= 121 * 10^(11+12)
= 121 * 10^23
= 1.21 * 10^25.
Note: True Scientific notation is N * 10^n where 1 ≤ N < 10.
The common difference of the data set of A is 1. While the common difference in the data set of B is 0.80
B.) 3.8 + 0.80 = 4.60
4.6 + 0.80 = 5.40
5.4 + 0.80 = 6.20
6.2 + 0.80 = 7.00
Answer=6 pieces
First lets convert 3/4 to ?/8...

3/4 is equivalent to 6/8.
Now we can divide 6/8 by 1/8

Answer=6 pieces
It would be -8d + 3w because
-(8d -3w)
you would be multiplying the hole equation by -1
so 8d would become -8d
and -3w would become positive +3w meaning the answer is -8d +3w
