A computer store decides to increase the prices of all the items it sells by 15%. The store manager uses matrices to prepare the

new price list. Matrix A contains the unit price of each product in each category. Matrix B contains the revised price of each item in each category. How can the manager obtain the entries for Matrix B?

The manager could perform scalar multiplication on Matrix A, using the scalar 1.15.

Increasing the price by 15% would mean we are taking 100% of the value + another 15%; 100+15 = 115%; 115% = 115/100 = 1.15.

Multiplying every value in Matrix A by 1.15 will give the price raised by 15%.

the sum of two consecutive even integers is greater than or equal to 34 what are the smallest possible integers?
DedPeter [7]

n, n + 2 - two consecutive even integers

the sum of two consecutive even integers is greater than or equal to 34

n + (n + 2) ≥ 34

n + n + 2 ≥ 34

2n + 2 ≥ 34       <em>subtract 2 from both sides</em>

2n ≥ 32      <em>divide both sides by 2</em>

n ≥ 16

<h3>Answer: The smallest possible integers is equal 16.</h3>

V = Ah ( A is the area of the base and h is the height )

Here A = 5 × 6 = 30 cm² and h = 7 cm , then

V = 30 × 7 = 210 cm³
