Answer:
every 1/4 inch on the map is 1 mile.
You need to find the number of 1/4 inches there are in 3 1/2 inches.
There are four 1/4 inches per inch.
3 x 4 = 12
There are two 1/4 inches in 1/2 inch.
12+2 = 14
The cities are 14 miles apart.
Answer:
20
Step-by-step explanation:
2 1/2 = 2 8/16
so
2 8/16 + 1 1/16 = 3 9/16
The answer is the third option
Answer:
(A+B)(A+B)=A.A+B.A+A.B+B.B
Step-by-step explanation:
Given that matrices A and B are nxn matrices
We need to find (A+B)(A+B)
For understanding the multiplication of matrices let'take A is mxn and B is pxq matrices,we can multiple only when n=p,so our Ab matrices will be mxq.
We know that that in matrices AB is not equal to BA.
Now find
(A+B)(A+B)=A.A+B.A+A.B+B.B
So from we can say that (A+B)(A+B) is not equal to A.A+2B.A+B.B because AB is not equal to BA in matrices.
So (A+B)(A+B)=A.A+B.A+A.B+B.B
Use the lengths of corresponding sides
so answer is 16:40 which simplifies to 2:5.
