Answer:
16/25 = 0.64
Step-by-step explanation:
18 rolls are ones, so 32 rolls are not ones.

Answer:
$2000
Step-by-step explanation:
For each pound, the charge is $40. There are 50 such charges. The point of multiplication is to simplify the process of repeated addition.
... 50 × $40 = $2000
ANSWER

EXPLANATION
For a matrix A of order n×n, the cofactor
of element
is defined to be

is the minor of element
equal to the determinant of the matrix we get by taking matrix A and deleting row i and column j.
Here, we have

M₁₁ is the determinant of the matrix that is matrix A with row 1 and column 1 removed. The bold entries are the row and the column we delete.

Since the determinant of a 2×2 matrix is

it follows that

so

Answer:
(f×g)(2) = 3/4
Step-by-step explanation:
For each of the functions, put 2 where x is and evaluate the expression.
f(2) = (3 -2)/(2² +4) = 1/8
g(2) = 3×2 = 6
Then the product is ...
(f×g)(2) = f(2)×g(2) = (1/8)×6 = 6/8
(f×g)(2) = 3/4
