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.

A rectangle has an area of 159.1m2. One of the sides is 3.7m in length. Work out the perimeter of the rectangle.

Answers

Answer:

93.4 m

Solution,

Area of rectangle=159.1 m^2

Length=3.7 m

Breadth=?

Now,

\(area \: of \: rectangle = l \times b \\ or \: 159.1 = 3.7 \times b \\ or \: 159.1 = 3.7b \\ or \: b = \frac{159.1}{3.7} \\ b = 43 \: m\)

Again,

Perimeter of rectangle:

\(2(l + b) \\ = 2(3.7 + 43) \\ = 2 \times 46.7 \\ = 93.4 \: m\)

Find the 24th term.
-9, 0, 9, 18, 27, ...
24th term = [? ]

Answers

Answer:

198

Step-by-step explanation:

Find the 24th term.-9, 0, 9, 18, 27, ...24th term = [? ]

Answer: 198

Step-by-step explanation:

Firstly, you must find the nth term.

the sequence is: -9, 0, 9, 18, 27, ...

find the difference between each term. in this sequence, the difference is 9, so it is 9n

then you must find the difference between the sequence 9n and this sequence. 9n is:

9, 18, 27, 36, 45, ...

now find the difference between 9n and our sequence.

adjustment = -18

so the nth term is 9n - 18

now you need to substitute 24, as that is the term you would like to find out, in place of n.

so, our n term looks like this: 9(24)-18

9 x 24 = 216

216 - 18 = 198

hence, the answer is 198.

hope this helps.

An image of a rhombus is shown.

a rhombus with a base of 18 centimeters and a height of 15.5 centimeters

What is the area of the rhombus?

16.75 cm2
33.5 cm2
139.5 cm2
279 cm2

Answers

Answer:279 cm²Step-by-step explanation:

Formula used,

Area of rhombus = Base × height

Substituting the values,

\( \longrightarrow\)Area = 18 × 15.5

\( \longrightarrow\) Area = 279 cm²

Therefore, 279 cm² is the area of the rhombus .

Answer:

D) 279 cm²

Step-by-step explanation:

Area of a rhombus formula:
\(A=bh\)

This formula is also used for squares and rectangles.

So, we can substitute in our values such as:

A=(18)(15.5)

simplify

A=279

Now, add our label and units:

A=279 cm²
