Angela wants to purchase carpeting for her living room. The dimensions of her living room are 15 feet by 18 feet. If carpeting is sold by the square yard, determine how many square yards of carpeting she must purchase.

Answers

Answer: 15 square yards of carpeting.

Hope this helps!

Pretty sure i'm wrong on this one but I can't figure it out either.

Sorry if I wasted your time.

Angela must purchase 29.7 square yards of carpeting.

How to Convert Square Feet to Square yards?

Multiply the area by the conversion ratio to convert a square foot measurement to a square yard measurement. Because one square foot equals 0.11 square yards, you may use the following easy formula to convert:

square inches = square feet × 0.11

The area in square inches is equal to the square feet multiplied by 0.11.

The dimensions of her living room are 15 feet by 18 feet.

The area in square feet is :

15 × 18 = 270 sq ft

Now, the area in square yards is :

270 × 0.11 = 29.7 sq yds

Thus, she must purchase 29.7 square yards of carpeting.

the answer is attached in the image

[tex]y = 650x[/tex] is an illustration of a linear function

The function is given as:

Because x represents time, it cannot take a negative number.

Also:

x can take a whole number or decimal numbers

Which statement is false? A All whole numbers are integers. B All integers greater than 0 are whole numbers. C No real numbers are irrational numbers. D No integers are irrational numbers.

Answers

no real numbers are irrational numbers

It is false that C. No real numbers are irrational numbers

Real numbers include both irrational and rational numbers so it is not true that a real number cannot be a rational number.

The other options are wrong because:

All whole numbers are indeed integers because integers are numbers that do not have to be written as fractions which makes them whole. All integers greater than 0 are whole numbers because they do not need to be written as fractions. Because integers are whole numbers, they cannot be irrational numbers which are numbers that go on forever e.g. π. Integers are whole which means that they can be completed.

Conclusively speaking therefore, the only false statement here is that no real numbers are irrational numbers.
