Visitors to a cinematic are either children, adults or pensioners. Ratio of children to adult visitors is 1:2 Ratio of adults to
VMariaS [17]

Ratio of children, adults and pensioners is 1 : 2 : 8/3 = 3 : 6 : 8.

Let, 3x is number of children.

So, 6x is number of adults and 8x is number of pensioners.

Now,

3x + 6x + 8x = 85

17x = 85

x = 5

Therefore, number of pensioners are 8×5 = 40.

Hence, this is the required solution.

Evaluate A + 3B if possible. HELP ASAP!
madreJ [45]

Answer:

Not possible.

Step-by-step explanation:

Addition of Matrix A and Matrix B is possible only if the order of matrix A is same as the order of matrix B.

Order of a matrix with m rows and n columns is m\times n.

Here, matrix A is \left[\begin{array}{ccc}2&-4\\-4&10\\0&-8\end{array}\right]

Matrix B is \left[\begin{array}{ccc}0&-4&6\\2&-10&4\end{array}\right].

Multiplying a matrix by a constant doesn't change its order.

So, order of matrix A is 3\times 2 as it has 3 rows and 2 columns.

The order of matrix 3B is 2\times 3 as it has 2 rows and 3 columns.

Therefore, addition is not possible as the order is different.
