Let f and s represent the weights of the first and second objects, respectively.
.. f - s = 200 . . . . . . . . the first is 200 lb heavier than the second
.. s = (1/3)f . . . . . . . . . . the second was 1/3 the weight of the first

In augmented matrix form, the equations can be written
.. f - s = 200
.. f - 3s = 0

The solution is
.. f = 300
.. s = 100
Their total weight is 400 lb, not enough to kill Mr. Boddy. The physics-loving professor is apparently innocent.

Mary has 50 earring boxes the boxes measure 1 inch on each side. How many rectangular prisms all with a different size base coul
Sholpan [36]
Given:
50 earring boxes with a measure of 1 inch each side

volume of boxes = a³ = 1³ = 1 in³
total volume of boxes = 1 in³ * 50 boxes = 50 in³

volume of a rectangular prism = length * width * height
50 in³ = length * width * height

Let us assume that the height is 1 in.

length and width can be factored:
50 x 1
25 x 2
10 x 5

Goryan [66]
78 x 100 = 7800 

<span>How many times does 190 go into 780? </span>
<span>≈ 4....190 x 4 = 760 </span>

<span>780 - 760 = 20...bring down the extra 0 to make it 200. </span>

<span>How many times does 190 go into 200? </span>
<span>≈ 1...subtract 190 from 200 to get a remainder of 10 </span>

<span>190 ÷ 7800 ≈ 41</span>

What is the correct expansion of (2x+3) (2x^2-5)
Dmitry_Shevchenko [17]

Answer:

4x^3 + 6x^2 -10x - 15

Step-by-step explanation:

* means multiply

4x^3 + 6x^2 -10x - 15

2x * 2x^2 = 4x^3

2x * -5 = 10x

3 * 2x^2 = 6x^2

3 * -5 = -15
