Insert 2 rational numbers between -1/3 and -1/2
Natalka [10]

Answer:

-11/24 and -4/9

Step-by-step explanation:

A rational number is a fraction in the form a/b where both a and b are integers and b is not equal to zero.

Given the numbers -1/3 and -1/2, to place two numbers between them, we have to first find the width between the two numbers.

Width = -1/3 - (-1/2) = -1/3 + 1/2 = 1/2 - 1/3 = 1/6

Since two numbers are to be placed between -1/3 and -1/2, we have to divide the width into 3 which results to 1/6 ÷ 3 = 1/18

The first number placed is -1/3 - 1/18 = -11/24

The second number is -11/24 - 1/18 = -4/9

Does the following infinite series have a sum or not and does it converge or diverge?
iren [92.7K]

Answer:

Step-by-step explanation:

Please present these numbers as a list:  7, -21, 63, -189, ....

Otherwise it appears that you are adding them up, which is not the case.

We can tell that this is a geometric series because each new number is -3 times the previous number:  -3(7) = -21, -3(-21) = 63, and so on.  Let r = -3 and a = first number = 7.

                                                                                                       a

The sum of an infinite geometric series exists if and only if |r} < 1.  Here, |-3|, or 3, so in this case the sum of the series does not exist.  That is, the series diverges.

The Epson workforce G7-1500 takes twice the time required by the Epson Workforce Pro GT-S50 to scan the manuscript for a book. I
neonofarm [45]
Let t be the time in minutes for the GT-S50 to scan the manuscript, working alone.
Then the G7-1500 will take 2t minutes to scan the manuscript, working alone.
If both machines work together for 1 minute they will scan 1/5 of the manuscript.
\frac{1}{t} + \frac{1}{2t} = \frac{1}{5}
\frac{3}{2t} = \frac{1}{5}
2t = 15
t = 7.5
When working alone, the machines will take the following times to scan the manuscript:
G7-1500: 15 minutes,    GT-S50: 7.5 minutes.
