Answer:

(3x +2)° + 28° = 180°

=> 3x = 180–30

=> x = 150/3

=> x = 50

Maddie's bedroom is rectangular. The length of one wall of Maddie's bedroom is 4 meters. The length from one corner of the bedro
salantis [7]

Answer:

The length of other wall is 3 meters.

Step-by-step explanation:

Given that:

Length of one wall = 4 meters

Length of diagonal from one corner to opposite corner = 5 meters

As the room is rectangular, the diagonal will form a right angled triangle.

The diagonal will be the hypotenuse.

Using pythagorean theorem;

a^2+b^2=c^2

Here,

a = 4 and c = 5

(4)^2+b^2=(5)^2\\16+b^2=25\\b^2=25-16\\b^2=9

Taking square root on both sides

\sqrt{b^2}=\sqrt{9}

b = 3 meters

Hence,

The length of other wall is 3 meters.

Kitty [74]

Given : Each Dentalia shell is about 1.5 inches long

⇒ Length of Necklace made with 24 Dentalia shells is (1.5 × 24) = 36 inches

⇒ Length of Necklace made with 18 Dentalia shells is (1.5 × 18) = 27 inches

We can notice that 24 Dentalia shells Necklace is Longer than 18 Dentalia shells Necklace

The Difference of Length of 24 Dentalia shells Necklace and 18 Dentalia shells Necklace gives how much longer the 24 Dentalia shells Necklace is than 18 Dentalia shells Necklace.

⇒ Difference = 36 - 27 = 9 inches

⇒ 24 Dentalia shells Necklace is 9 inches longer than 18 Dentalia shells Necklace

The solution to a problem is an irrational number. Which statement is true about the solution?
navik [9.2K]

Group of answer choices.

A. It can be expressed as a non repeating, non terminating decimal.

B. It can be a perfect square

C. It cannot be pie π

D. It is not possible to have a irrational number solution.​

Answer:

A. It can be expressed as a non repeating, non terminating decimal.

Step-by-step explanation:

An irrational number can be defined as real numbers that cannot be expressed as a simple fraction or ratio of two integers.

Additionally, it is the opposite of a rational number and as such its decimal is continuous without having any repetition or termination. For example, pie (π) = 3.14159 is an example of an irrational number.

Assuming the solution to a mathematical problem is an irrational number. The statement which is true about the solution is that it can be expressed as a non-repeating, and non-terminating decimal.
