Tomtit [17]

Answer:

US$ 132.45

Step-by-step explanation:

See attachment for the missing table.

Given:

Richard’s checking account balance at the beginning of the week = $57.34

<u>Richard’s account balance at the end of the week from the given table:</u>

Deposits of the week = US$ 163.75

Expenses of the week = Groceries + Credit card bill + Gas

Expenses of the week = 25.37 + 50 + 13.27

Expenses of the week = US$ 88.64

Richard’s account balance at the end of the week = Richard’s checking account balance at the beginning of the week + Deposits of the week - Expenses of the week

Replacing with the real values:

Richard’s account balance at the end of the week = 57.34 + 163.75 - 88.64

                                                                                    =US$ 132.4

A packing company is doing an inventory of boxes. Their most popular box is display below: 2ft,(3x-5)ft,(2x-1)ft you can use the
Angelina_Jolie [31]

Answer:

The value of x  = 3.

Length = 4 feet and Width = 5 feet

Step-by-step explanation:

Height of the box = 2 ft

Length of the box = (3x-5) ft

Width of the box  = (2x-1) ft

Volume of the box = 40 cubic feet

Now, VOLUME OF CUBE  = LENGTH x WIDTH x HEIGHT

\implies 40 = 2 \times (3x-5) \times (2x-1)\\\implies 20 = 3x(2x-1)) -5 (2x-1) = 6x^2 - 3x -10x +5  = 6x^2 - 13x + 5\\\implies  6x^2 - 13x -15 = 0

Now, solving for the value of x, we get:

6x^2 -13 x - 15  = 6x^2 -18x + 5x - 15 = 0\\\implies6x(x-3) + 5(x-3) = 0\\\implies (x-3)(6x+5) = 0

⇒ Either x-3 = 0, or ( 6x+5) = 0

⇒ Either x  = 3, or x = -5/6

As x = SIDE OF A CUBE ,so it CANNOT be negative.

⇒x  = 3

So, length = (3x-5)  = 3(3) -5 = 9-5 = 4 units

Width = (2x-1) = 2(3) -1  = 5 units
