Four friends each purchased a hat for $12.50

mrs_skeptik [129]

Answer:

$70 each

Step-by-step explanation:

If 4 friends each buy a hat, that would be $50 because that is $12.50X4=%50.00. Then, Since the total is $190 and $50 is off the chart, you would be left with $140 to spend on two t-shirts. Finally, since they are the same price, you divide $140/2=$70. Each t-shirt is $70.

Let me know if you need clarification and I will help the best I can. Have a nice day. :)

Determine if the product CA is defined. If the product is defined, state its dimensions. Do not calculate the product.

Troyanec [42]

ANSWER

The multiplication, CA is defined, and its dimension is 3×2

EXPLANATION

Matrix A is a 2x3 matrix.

Matrix C is a 3×2 matrix.

The product of the two matrices , CA, is defined if and only if the inner product of their dimension are the same.

$CA = (2 \times 3)(3 \times 2)$

The inner products are the same.

Hence the matrix multiplication, CA is defined and its dimension is the outer products.

$2 \times 2$
