Tamara sold 5 large and 6 small cartons of ice cream.
Bear in mind that, is an isosceles
right-triangle, so, one angle is 90°.
check the picture below.
Answer:
The base and height of the solid is 5.5cm
<em></em>
Step-by-step explanation:
Given

Required
Determine the dimensions that maximizes the volume
Let the base dimension be x and the height be h
The volume is calculated as:


181.5 =x^2h
The surface area (S) is calculated as this:



Substitute 181.5 for S

Make h the subject:


Substitute
in 





To get the maximum, we differentiate V with respect to t and set the differentiation to 0

Set to 0


Multiply through by 4







Recall that:





So, we have:


<em>Hence, the base and height of the solid is 5.5cm</em>
5% of 15 is 0.75
15 - 0.75 = 14.25
So it the sale price $14.25 ?
Oh gosh….this is my personal nightmare. i’m sorry i don’t know
