Mathematics

Answer:

Simplified expression: $\frac{1}{y+8 }$ .

The value of y that makes the expression undefined is y=-8.

Step-by-step explanation:

$\frac{2y^{3}}{2y^{4}+16y^{3}}$

= $\frac{2y^{3}}{2y^{3}(y+8) }$

(cancel out 2y³)

= $\frac{1}{y+8 }$

A rational expression is undefined when the denominator (bottom number) is zero. So, if y equalled -8, the expression would ultimately equal $\frac{1}{0}$ , which is undefined.

Morty buys and sells computer parts

mart [117]

Answer:

1. Morty's total cost for the items he purchased was $210

2. Morty's revenue from the sale of the items was $547

3. Morty's Total profit was $337

Explanation:

The complete question is:

Morty buys and sells computer parts. He bought two monitors for $25 each and later sold them for $88 each. He bought four cases for $15 each and later sold them for $24 each. He bought five memory modules for $20 each and later sold them for $55 each.

Morty's total cost for the items he purchased was

Morty's revenue from the sale of the items was

Morty's Total profit was

<h2>Solution</h2>

1. Morty's total cost for the items he purchased was

Build a table with the number of parts and their costs:

Component Amout Unit cost Total cost

$ $

Monitors 2 25 50

Cases 4 15 60

Memory 5 20 100

Total cost = $50 + $60 + $100 = $210

2. Morty's revenue from the sale of the items was

Build a table with the number of parts and their selling prices:

Component Amout Unit price Total cost

$ $

Monitors 2 88 176

Cases 4 24 96

Memory 5 55 275

Total revenue: $176 + $96 + $275 = $547

3. Morty's Total profit was 

The total profit is the total revenue less the total cost: $547 - $210 = $337.

A. A 5in radius ball is in a

abruzzese [7]

Answer:

52.33%

Step-by-step explanation:

Since, all six sides of the box are touching the ball.

So, all the three dimensions of the box are equal.

Hence, it is a cubical box.

Side length of the box (l)

= diameter of the ball

= 2*radius of the ball

= 2*5

= 10 In.

$V_{ball} = \frac{4}{3} \pi r^3$

$V_{ball} = \frac{4}{3} \times 3.14(5)^3$

$V_{ball} = \frac{4}{3} \times 3.14\times 125$

$V_{ball} = \frac{1,570}{3}\: In^3$

$V_{box} =l^3$

$V_{box} =(10)^3$

$V_{box} =1000\: In^3$

Percentage of the space in the box occupied by the ball

$= \frac{V_{ball}}{V_{box} } \times 100$

$= \frac{\frac{1,570}{3}}{1000} \times 100$

$= \frac{1570}{3000} \times 100$

$= \frac{157}{3}$

$= 52.33\%$

What is the simplified form of x+3/4+x+2/4

Savatey [412]

Hey there! :D

Since all the terms are being added together, and there is a common denominator with the fractions, we can just add them.

x+x= 2x 3/4+2/4= 5/4

2x+5/4

2x+1.25<== simplest form

I hope this helps!
