Answer:

<h2>x > 1.8</h2>

Step-by-step explanation:

\dfrac{2}{3}x-\dfrac{1}{5}>1\qquad\text{multiply both sides by 15}\\\\15\!\!\!\!\!\diagup^5\cdot\dfrac{2}{3\!\!\!\!\diagup_1}x-15\!\!\!\!\!\diagup^3\cdot\dfrac{1}{5\!\!\!\!\diagup_1}>15\cdot1\\\\(5)(2x)-3>15\qquad\text{add 3 to both sides}\\\\10x>18\qquad\text{divide both sides by 10}\\\\\boxed{x>1.8}

Answer:

Step-by-step explanation:

<em>Let one number = x </em>

<em>Let the other number = y </em>

<em>  </em>

<em>x + y = 9 </em>

<em>  </em>

<em>xy2  is a maximum </em>

<em>  </em>

<em>  </em>

<em>Since we need positive numbers, we assign values of x and y respectively that will give us a sum of 9. </em>

<em>  </em>

<em>x: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 </em>

<em>  </em>

<em>y: 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 </em>

<em>  </em>

<em>  </em>

<em>Next, we square the values of y. </em>

<em>  </em>

<em>y2: 81, 64, 49, 36, 25, 16, 9, 4, 1, 0 </em>

<em>  </em>

<em>  </em>

<em>Next, we multiply x by y2 to see which product is the highest value. </em>

<em>  </em>

<em>x  : 0  , 1  , 2  , 3 , 4  , 5  , 6, 7, 8, 9 </em>

<em>y2 : 81, 64, 49, 36, 25, 16, 9, 4, 1, 0 </em>

<em>  </em>

<em>  </em>

<em>We can eliminate x = 0, x = 8 , and x = 9 , since the product of xy2 is of lowest value. </em>

<em>  </em>

<em>1 x 64 = 64 </em>

<em>2 x 49 = 92 </em>

<em>3 x 36 = 108 </em>

<em>4 x 25 = 100 </em>

<em>5 x 16 = 80 </em>

<em>6 x 9 = 54 </em>

<em>7 x 4 = 28 </em>

<em>  </em>

<em>The highest product value here is 108.  </em>

<em>  </em>

<em>The two numbers in the solution are 3 and 6.</em>

The formula to find the surface area (S) of a rectangular prism with a length (l), a width (w) and a height (h) is:
erica [24]

Answer:

148 in^3

Step-by-step explanation:

S= 2lw + 2wh + 2lh

S = (2 x 5 x 4) + (2 x 4 x 6) + (2 x 5 x 6)

S = 40 + 48 + 60

S = 148

Hope this helps
