A literal equation has only one variable.
True
False

Answers

<b>The answer is False.</b>

<b>The reason is that, the letters or variables in a literal equation are like parameters that can be any real number.</b>

A literal equation has two or more variables or letters, that are used to represent real values.

An example is the perimeter of a square, which is given by the formula,

P=4l
Here, the P represents perimeter of the square and l represents the length of the square.

Since the length of a square can assume any positive value,the above literal equation has <b>infinitely many solutions</b>.

For instance, if

l=1, P=4*1=4

l=2, P=4*2=8

and so on and so forth.

Other examples of literal equations include:

The perimeter of a rectangle, which is given by the formula:

P=2w + 2l

The formula for finding the perimeter of a circle:

C = 2 \pi \: r

The set of values that satisfy the above formulas are infinitely many.

This statement is actually false.

A 10 inch diameter pumpkin pie is cut into 6 equal servings. What is the area of the top of each piece of pie?

Answers

The area (A) of the whole circle is calculated through the formula, A = πd² / 4. Substituting the given diameter, A = π(10 in)² / 4 = 25π in². The area of the top of each piece is 1/6 of the this area. Thus, the answer is approximately 4.17 in².

Triangle XYZ has been dilated to form triangle LMN. What is the least amount of information needed to prove the two triangles are similar?A.Two pairs of corresponding angles and one pair of corresponding sides

B.Two pairs of corresponding sides and one pair of corresponding angles

C.Two pairs of corresponding angles

D.Two pairs of corresponding sides

Answers

Answer:

Option C is correct.

Two pairs of corresponding angles

Step-by-step explanation:

Given triangle XYZ has been dilated to form triangle LMN.

Dilation states that it is a transformation that produces an image that is the same shape as the original, but of a different size.

therefore, the triangle XYZ  by a dilation is similar to triangle LMN

Similar figures have the

*same shape

*equal corresponding angle measures, and

*have proportional sides.

Therefore, the information which is needed to prove that two given triangles are similar is two pairs of corresponding angles

Two pairs of corresponding angles

Multiply.–6 • (–12)

A.
72

B.
–18

C.
–72

D.
18

Answers

first you should know that when two negative numbers multiply by each other the answer will be positive so we can say : 6 * 12 = 72 so the answer is A
