Please solve these equations much appreciated
Reptile [31]

Answer:      

Part c) V=16,500\ m^3

Part d) V=93,312\pi\ mm^3  or V=292,999.68\ mm^3

Step-by-step explanation:

Part c) Find the volume of the inverted rectangular pyramid

The volume of the rectangular pyramid is equal to

V=\frac{1}{3}Bh

where

B is the area of the rectangular base

h is the height of pyramid

<em>Find the area of the base B</em>

B=(60)(15)=900\ m^2

h=55\ m

substitute

V=\frac{1}{3}(900)(55)

V=16,500\ m^3

Part d) Find the maximum volume of tea in the tea cup

we know that

The volume of cylinder (tea cup) is equal to

V=\pi r^{2}h

we have

r=36\ mm\\h=72\ mm

substitute

V=\pi (36)^{2}(72)

V=93,312\pi\ mm^3 -----> exact value

<em>Find the approximate value</em>

assume

\pi =3.14

V=93,312(3.14)=292,999.68\ mm^3

Tom [10]

p = 12x is the  function rule to calculate the total number of pens when you know the number of boxes

<em><u>Solution:</u></em>

Given that,

Pen are shipped to the office supply store in boxes of 12 each

To find: Write a function rule to calculate the total number of pens when you know the number of boxes

Let "p" be the total number of pens

Let "x" be the number of boxes

Number of pens in each box = 12

Then from given information,

Total number of pens = Number of boxes multiplied by number of pens in each box

p = x \times 12\\\\p = 12x

Thus the function rule is found
