Answer
54 students are in the science club
Step-by-step explanation:
84 divided by 2 = 42
42 + 12 =54
84 - 54 = 30
so the science club has 54 students and the robotics club has 30 students
Answer:
Step-by-step explanation:
For two matrix P and Q, the product, say PQ is defined when:
The number of columns of P = The number of rows of Q
Since A is a 2×2 matrix and B is also a 2×2 matrix
Thus both AB and BA are possible.
So AB is:
BA is:
(2.5*10^-8)(9*10^-10)
First, distribute a 1 so you can get rid of parentheses
2.5*10^-8*9*10^-10
Now, combine like terms
(2.5*9) (10^-8*10^-10)
2.25*10^-18
Answer:
83+136
