If b\7=7\1 ,,, soo then b= A) 35,,, B)5,,, C) 40,,, D) 12 so which one is the answer
iVinArrow [24]
B/7 = 7....multiply both sides by 7
b = 7 * 7
b = 49
Answer:
Step-by-step explanation:
Since the numbers are consecutive, the square root of the product will be a value between them.
√132 ≈ 11.49
so, the consecutive numbers are 11 and 12. (11×12 = 132)
The catcher's number is smaller, so is 11; the pitcher's number is 12.
Answer:
D. 19
Step-by-step explanation:
because they are parallel bases you can compare
63/57 = 21/x
x = 19
Answer:
A, B, D, F
Step-by-step explanation:
Matrix operations require that the matrix dimensions make sense for the operation being performed.
Matrix multiplication forms the dot product of a row in the left matrix and a column in the right matrix. That can only happen if those vectors have the same dimension. That is the number of columns in the left matrix must equal the number of rows in the right matrix.
Matrix addition or subtraction operates on corresponding terms, so the matrices must have the same dimension.
The transpose operation interchanges rows and columns, so reverses the dimension numbers. It is a defined operation for any size matrix.
