Answer:

Any irrational number is added to 0.4 it will give an irrational number.

Step-by-step explanation:

We need to tell the number which produces an irrational number when added to 0.4.

An irrational number is a number which cannot be expressed in the form of fraction \frac{x}{y}. In other words we can put that decimal expansion of an irrational number does not terminate or cease to end.

Now, if any irrational number is added to 0.4 it will give an irrational number.

Some examples could be: \sqrt2, \sqrt3, \pi and any non-terminating number.

George has only Quarters and nickels in his piggy bank.He has a total of 90 coins.The value of the coins is $16.10. Write and so
son4ous [18]

Answer:

The number of

Quarters = q = 58 quarters

Nickels = n = 32 nickels

Step-by-step explanation:

It is important to note that:

A quarter is worth 25 cents = 0.25q

A nickel is worth 5 cents = 0.05n

George has only Quarters and nickels in his piggy bank.

Let the number of

Quarters = q

Nickels = n

He has a total of 90 coins.

Hence,

q + n = 90.... Equation 1

q = 90 - n

The value of the coins is $16.10.

Hence,

0.25q + 0.05n = 16.10....Equation 2

We substitute 90 - n for q in Equation 2

0.25(90 - n) + 0.05n = 16.10

22.5 - 0.25n + 0.05n = 16.10

Collect like terms

- 0.25n + 0.05n = 16.10 - 22.5

-0.2n = - 6.4

n = -6.4/-0.2

n = 32 nickels

Solving for q

q = 90 - n

q = 90 - 32

q = 58 quarters

Therefore, the number of

Quarters = q = 58 quarters

Nickels = n = 32 nickels

Ben thinks that the largest place value that 5.6 and 1.78 have in common is the tenths place. Nichole thinks that the largest pl
-Dominant- [34]

The place values in 5.6 and 1.78 are the positions of the digits in the numbers

  • The largest place value common in 5.6 and 1.78 is the ones place
  • Nichole is correct

<h3>How to determine who is correct?</h3>

In a number, the non-zero digit at the left-most position is the greatest place value

This means that:

The greatest place value in 5.6 is 5 (i.e. ones place)

The greatest place value in 1.78 is 1 (i.e. ones place)

So, we can conclude that the largest place value common in 5.6 and 1.78 is the ones place

Hence, Nichole is correct
