What is the volume of the planter that measures 60l, 60w. 60h?

andre [41]

The volume of the planter that measures 60 l, 60 w. 60 h (D) 216000 cm³

<u>Explanation:</u>

Length, l = 60 cm

Width, w = 60 cm

Height, h = 60 cm

Volume, v = ?

We know,

Volume = length ×width × height

Substitute the values in the formula.

$v = 60 X 60 X 60\\\\v = 216,000 cm^3$

Therefore, the volume of the planter is 216,000 cm³

Peter has 3200 yards of fencing to enclose a rectangular area. Find the dimensions of the rectangle that maximize the enclosed a

salantis [7]

Answer:

$A = 640000\,yd^{2}$

Step-by-step explanation:

Expression for the rectangular area and perimeter are, respectively:

$A (x,y) = x\cdot y$

$3200\,yd = 2\cdot (x+y)$

After some algebraic manipulation, area expression can be reduce to an one-variable form:

$y = 1600 -x$

$A (x) = x\cdot (1600-x)$

The first derivative of the previous equation is:

$\frac{dA}{dx}= 1600-2\cdot x$

Let the expression be equalized to zero:

$1600-2\cdot x=0$

$x = 800$

The second derivative is:

$\frac{d^{2}A}{dx^{2}} = -2$

According to the Second Derivative Test, the critical value found in previous steps is a maximum. Then:

$y = 800$

The maximum area is:

$A = (800\,yd)\cdot (800\,yd)$

$A = 640000\,yd^{2}$

Celia sells calendars for fundraiser. Each calendar cost $9. She sells 16 calendars to her family members and 14 calendars to th

Sunny_sXe [5.5K]

Answer:

Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal .

Step-by-step explanation:

Given as :

The cost of each calendar = $ 9

The number of calendar sold to the family = 16

The number of calendar sold to the neighborhood = 14

So, Total number of calendar sold by Celia = The number of calendar sold to the family + The number of calendar sold to the neighborhood

i.e Total number of calendar sold by Celia = 16 + 14 = 30

∵ The cost of each calendar = $ 9

∴ The cost of 30 calendar = $ 9 × 30 = $ 270

Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal . Answer
