Answer: You bought 3.5 pounds.
Step-by-step explanation: Okay so it costs $12 to get two pounds of jelly beans. You divide 12 by 2 and end up getting 6. You then divide 21 by 6 and get 3.5 because each pound is 6. 2 pounds is 12, and 3.5 pounds is $21. I hope this helped! :P
Answer:
To have maximum profit, the price must be increased by 5,
Step-by-step explanation:
Given that the price increase function is:
f(x) = -2x² + 20x + 150,
For maximum profit, then f(x) = 0.
Putting f(x) = 0, we have
-2x² + 20x + 150 = 0
Or
x² - 10x - 75 = 0
(x + 5)(x - 15) = 0
x = -5
Or
x = 15
Again, differentiating f(x) and equating to zero, we have
-4x + 20 = 0
4x = 20
x = 20/4
= 5
To have maximum profit, the price must be increased by 5,
Answer:
<h2><em><u>126</u></em></h2>
Step-by-step explanation:
<em>In</em><em> </em><em>number</em><em> </em><em>4</em><em> </em><em>the</em><em> </em><em>given</em><em> </em><em>figure</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>parallelogram</em><em>, </em>
<em><u>So</u></em><em><u>,</u></em>
Base of the parallelogram = 14
Height of the parallelogram = 9
<em><u>Therefore</u></em><em><u>, </u></em>
Area of the parallelogram = <em><u>Base</u></em><em><u> </u></em><em><u>×</u></em><em><u> </u></em><em><u>Height</u></em><em><u> </u></em>
= 14 × 9
= 126
<em><u>Hence</u></em><em><u>,</u></em><em><u> </u></em><em><u>area</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>figure</u></em><em><u> </u></em><em><u>in</u></em><em><u> </u></em><em><u>question</u></em><em><u> </u></em><em><u>no</u></em><em><u>.</u></em><em><u> </u></em><em><u>4</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>12</u></em><em><u>6</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
