The number of hours that it'll take both printers to do the job is 2.4 hours.

<em>Number of hours used by printer A = 6 hours</em>

<em>Number of hours used by printer B = 4 hours </em>

<em />

Therefore, the number of hours that'll be used by both printers will be calculated thus:

1/6x + 1/4x = 1

Using 12 as the LCM

2x + 3x = 12

5x = 12

Divide both side by 5

5x/5 = 12/5

x = 2.4 hours

A japanese beetle has a length between 0.3 and 0.5 inch.find two lengths that are within the given span.express them as a fracti
DanielleElmas [232]
Hello,

One method of finding a value in between two other numbers is taking the average, it will always be between the numbers. To find the average of two numbers, add the numbers and divide it by how many numbers there are. 

In this case, we have:
(0.3) + (0.5) /2 = 0.8 / 2 = 0.4

So, 0.4 is one length that is within the given span.
Another example is 0.45, which is also between 0.3 and 0.5.

0.4 represented as a fraction is 4/10. However, this can be simplified (notice 4 and 10 are both divisible by 2). To simplify this fraction, divide the numerator and denominator of the fraction by 2 to get (4/2) / (10/2) = 2/5.

0.45 represented as a fraction is 45/100. This fraction can also be simplified (notice 45 and 100 are both divisible by 5). To simplify this fraction, divide the numerator and denominator of the fraction by 5 to get (45/5) / (100/5) = 9/20.

Two lengths that are within the span are 2/5 inches and 9/20 inches, both of which are in simplest form.

Hope this helps!

A 96 inch stick breaks into two pieces in the ratio of 3:5. How big is each piece?
Svetlanka [38]
40 cm.

let the length of the first part be 3x, second part be 4x, third part be 5x.

where x is a positive length in cm.

why 3x,4x and 5x ?

so that the ratio of lengths of the 3 parts be 3:4:5.

total length of the stick = 3x + 4x + 5x = 12x=96cm

so x=96/12 = 8cm

therefore the largest part of the stick (5x)= 5*8 =40cm

Mathew buys a single ticket for $8 out of a lottery of 1000 tickets where the prize for the one winning is to be $800. How much
miss Akunina [59]

Given:

The number of tickets = 1000

Mathew buys a single ticket for $8

Winning price = $800

To find:

The expected earning per ticket.

Solution:

It is given that the total number of tickets is 1000. So, the probability of winning is:

P(Winning)=\dfrac{1}{1000}

The probability of losing is:

P(losing)=\dfrac{999}{1000}

The expected earning per ticket is:

E(x)=800\times P(Winning)-8\times P(losing)

E(x)=800\times \dfrac{1}{1000}-8\times \dfrac{999}{1000}

E(x)=\dfrac{800}{1000}-\dfrac{7992}{1000}

E(x)=\dfrac{800-7992}{1000}

E(x)=\dfrac{-7192}{1000}

E(x)=-7.192

Therefore, the expected earning per ticket is -7.192. Here, negative sign means loss of $7.192.
