8. The volume of the pyramid is 168 cubic inches. Find the length of the rectangular base. (3pts)7 inI8 in.
olya-2409 [2.1K]

The length of the rectangular base is 9in

<h3>How to determine the value</h3>

It is important to note that the formula for determining the volume of a pyramid with rectangular base is expressed as;

Volume = lwh/3

Where;

  • l is the length of the rectangular base of the pyramid
  • w is the width of the rectangular base of the pyramid
  • h is the height of the rectangular base of the pyramid

Given the value of the volume, width an height of the pyramid as 168, 7 and 8, we substitute the values, we have;

168 = l × 7 × 8/ 3

cross multiply

l × 7 × 8 = 168(3)

Find the product

56l = 504

To determine the length, divide both sides by 56, we get;

l = 504/ 56

l = 9In

Hence, the value is 9in

\tan(16)  =  \frac{8.3}{x}  \\

0.2867453858 =  \frac{8.3}{x}  \\

Thus :

x =  \frac{8 .3}{0.2867453858}  \\

x = 28.9455398797

and United States Lowe's sells particular carpet for $4.88 per square foot in the United Kingdom carpetright sells assembler car
Alisiya [41]

The carpet of United Kingdom carpet-right is cheaper by 3.33 dollars/ft²

<u><em>Explanation</em></u>

Price of the carpet in United States Lowe's is 4.88 dollars/ft²

Price of the carpet in United Kingdom carpet-right is 12.99 pound sterling/m²

1 pound sterling = 1.28 US dollars and 1 meter = 3.28 ft . So....

12.99 pound sterling/ m²

=\frac{(12.99) pound sterling}{(1 meter)^2}\\ \\ = \frac{(12.99*1.28)dollars}{(3.28 ft)^2} =\frac{16.6272 dollar}{10.7584 ft^2}= 1.55 dollar/ft^2

<u>As the unit price of the carpet per square feet in United Kingdom carpet-right is less than United States Lowe's</u>, so the carpet of United Kingdom carpet-right is cheaper by (4.88-1.55)dollar/ft^2 = 3.33 dollar/ft^2

yKpoI14uk [10]

Answer:

Regina drank 2/4 gal. of orange juice

Step-by-step explanation:

She starts off at 3/4 which makes the equation: 3/4 - 1/4=x

3/4-1/4 equals 2/4 which gets reduced and simplified to 1/2.
