x = 3.242424242424

100x = 324.24242424242424242424

-x

= 329/99

3-24/99

3 8/33

Answer:

A, 3 8/33.

Step-by-step explanation:

x = 3.242424.....

100x = 324.2424.....

If we subtract, we get 99x = 324.2424... - 3.2424.... = 321.

99x = 321

x = 321 / 99 = 107 / 33 = 3 8/33

How many places to the left should the decimal point be moved to write 7.2 × 10-9 in standard form?

Answers

Answer: To write a large number in scientific notation, move the decimal point to the left to obtain a number between 1 and 10. Since moving the decimal point changes the value, you have to multiply the decimal by a power of 10 so that the expression has the same value.

You used 1/8 of a bag of dirt to fill 1/12 of your garden box. How many bags of dirt are needed to fill one garden

Answers

Answer:

1 1/2 bags

Step-by-step explanation:

given 1/8 of a bag will fill up 1/12 of a garden box, i.e.

1/8 bag ------> fills 1/12 box   (rearrange this)

1/12 box ----> requires 1/8 bag

to find how many bags it takes to fill 1 box, we simply multiply both sides of this equation by 12 to get the unit rate of fill

( 1/12 ) x 12 box -----> requires (1/8) x 12  bags

1 box ------> requires 12/8 = 3/2 = 1 1/2 bags  (answer)

I’m pretty sure it’s 1 1/2 bags

Jacinta says that the product of a rational number and an irrational number is always irrational. Explain her error.

Answers

if u multiply an irrational number by 0 the result will be 0 which is a rational number. Except this case, other times will result with irrationals.

Jacinta says that the product of a rational number and an irrational number is always irrational her claim is wrong.

What is a rational number?

A rational number is one that can be stated mathematically as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively.

Irrational numbers are all real numbers that are not rational numbers in mathematics. Irrational numbers, on the other hand, cannot be stated as the ratio of two integers. Decimal notation is the term used to describe the method of representing numbers in the decimal system.

Given that Jacinta says that the product of a rational number and an irrational number is always irrational.

Her statement is incorrect because if 0 a rational number is multiplied with the π which is irrational then the result will be 0 which is rational.

Therefore, Jacinta's claim is wrong.
