Answer:

63.5minutes

Step-by-step explanation:

Let the time it takes the small pipe to fill the tank be x

Let the time it takes the larger pipe to fill the tank be y

If the two pipes can fill a tank in 98 minutes if both are turned on then:

x+y = 98...1

If only one is used and it takes 29 minutes longer for the smaller pipe to fill the tank than the larger pipe

x = 29+y... 2

Substituting equation 2 into 1 to get y we have:

29+y+y = 98

29+2y = 98

2y = 98-29

2y = 69

y = 69/2

y = 34.5minutes

x = 29+34.5

x = 63.5

This means it will take the smaller pipe 63.5minutes to fill the tank

Find two irrational numbers between 0.3 and 0.7?
Vesnalui [34]

Answer:

0.3101001000......

0.410100100010000....

Step-by-step explanation:

To find irrational number between any two numbers, we first need to understand what a rational and irrational number is.

Rational number is any number that can be expressed in fraction of form p/q. Since q can be 1, all numbers that terminate are rational numbers. Example: 1, 12.34, 123.66663

Irrational number on the other hand can't be expressed as a fraction and do not terminate. Also, there is no pattern in numbers i.e. there is no repetition in numbers after the decimal point.

For example: 3.44444..... can be expressed as rational number 3.45.

But 3.414114111.... is an irrational number as there no pattern observed. Also,it does not terminate.

We can find infinite number of irrational numbers in between two rational numbers.

<u>Irrational numbers in between 0.3 and 0.7:</u>

0.3101001000......

0.410100100010000....

0.51010010001.......

0.6101001000....

There are many others. We can choose any two as answers.

mina [271]

Pablo is correct because , the number 0.8759 is rational number because it doesn't go on like pi or the square root of 2 it stops at a certain point and was probably rounded . I'm not sure if its 100% correct.

Hope this helps!
