if the length of the container is half of a foot longer than it’s width what expression represents the height of the container

liberstina [14]

Answer:

The height of the container is $7x\ ft$

Step-by-step explanation:

Let

L ------> the length of the rectangular container

W ----> the width of the rectangular container

H ---> the height of the rectangular container

we know that

The volume of the rectangular container is

$V=LWH$ ------> equation A

we have

$W=x\ ft$

$L=(x+0.5)\ ft$

$V=7x^{3}+3.5x^{2}$

substitute the values in the equation A

$7x^{3}+3.5x^{2}=(x+0.5)(x)H$

Factor the term x in the left side

$(7x^{2}+3.5x)(x)=(x+0.5)(x)H$

Simplify

$(7x^{2}+3.5x)=(x+0.5)H$

Factor the term 7x in the left side

$(7x)(x+0.5)=(x+0.5)H$

Simplify

$(7x)=H$

Rewrite

$H=7x\ ft$

X is bigger than 65 but smaller or equal to 69. Looks a bit like this...6569.
(However “>“ is a little different as there should be a line under it to show how it can be equal to 69.

Two regular hexagons have sides in the ratio 3:5. The area of the smaller hexagon is 81 m2. What is the area of the larger hexag

Aliun [14]

If the sides are in the ratio of 5:3 then the area will increase by a factor of:(5 / 3) ^2
(5 / 3)^2 = 2.777777777 
Area of small hexagon = 81
Area of larger hexagon = 81 * 2.777777777
Area of larger hexagon = 225 square meters
