Which multiplication has a negative answer?A) (-1)(-1)
B) (-1)(-1)(-1)(-1)
C) (-1)(-1)(-1)(-1)(-1)
D) (-1)(-1)(-1)(0)

Answers

To find out quickly if multiplication will be positive or negative,  count the number of negative signs in each equation. If it comes out even,  it is positive.  If odd, it will come out negative.  Only exception is when 0 is in the mix.  First equation has 2,  therefore is positive because even.  Second has 4,  which is another positive because even.  3rd is 5, which is negative because it is odd and has NO 0.  4th has 0.

Cindy says that 1/3 is an irrational number because the fraction form doesn't terminate. Construct an argument to support or refute Cindy's position.

Answers

It’s not an irrational number because it can be written as a decimal. It is in an infinite decimal but if anything can be written as a fraction it is not a irrational number. :))

Final answer:

Cindy's argument is incorrect. 1/3 is a rational number because it can be expressed as the ratio of two integers. The fact that the decimal representation of 1/3 does not terminate does not make it irrational.

Explanation:

Cindy's argument is incorrect. A fraction is considered irrational if it cannot be expressed as the ratio of two integers. In the case of 1/3, it can be expressed as the division of the integer 1 by the integer 3, so it is a rational number. The fact that the decimal representation of 1/3 (0.333...) does not terminate does not make it irrational. Irrational numbers are decimal numbers that do not repeat or terminate, such as π (pi) and √2 (the square root of 2).

90 degrees angle means the triangle is a right angle and all the sides arent the same so it is also scalene

Letters x, y, and z are angle measures. Which equations would guarantee that lines p and q are parallel? Check all that applyx = z


x + y = 180°


x + z = 180°


x = y


y + z = 180

Answers

we know that

If lines p and q are parallel

then

x=z---------> by corresponding angles

x+y=180\° -------> by consecutive interior angles

Let's verify all the equations to determine the solution to the problem.

Equations

case A)x=z

The equation guarantees that the lines p and q are parallel (see the procedure)

case B)x+y=180\°

The equation guarantees that the lines p and q are parallel (see the procedure)

case C)x+z=180\°

The equation does not guarantee that the lines p and q are parallel. The only way would be that x-angle and z-angle are right angles

case D)  x=y

The equation does not guarantee that the lines p and q are parallel. The only way would be that x-angle and y-angle are right angles

case E)  y+z=180\°

The equation is always true, but toes not guarantee that the lines p and q are parallel.

therefore

the answer is

x=z

x+y=180\°

Answer:  The correct options are

(A) x = z.

(B) x + y = 180°.

Step-by-step explanation:  Given that the letters x, y and z are angle measures.

We are to select the correct equations that would guarantee that lines p and q are parallel.

Since the lines p and q are parallel, so

(i) the angles with measures x and y are interior angles on the same side of the transversal

and

(ii) the angles with measure x and z are corresponding angles.

We know that

if two parallel lines are cut by a transversal, then the measures of the corresponding angles are equal

and

the sum of the measures of the interior angles on the same side of the transversal is 180°.

Therefore,

x + y =180°, since they are interior angles on the same side of the transversal

and

x = z, since they are corresponding angles.

Thus, the correct options are

(A) x = z.

(B) x + y = 180°.

146 dan 105

Further explanation

Given:

Two numbers add to 251 and the second is 41 bigger than the first.

Question:

What are the two numbers?

The Process:

Let the first number we call x, and the second number is y.

Two numbers add to 251, We arrange it as Equation-1:

\boxed{ \ x + y = 251 \ }

The second is 41 bigger than the first. We arrange it as Equation-2:

\boxed{ \ x = y + 41 \ } \ or \ \boxed{ \ x - y = 41 \ }

Let us solve the two equations above by eliminating the same variable. With the addition process, it appears that the variable y will be eliminated.

x + y = 251

x - y = 41

-------------- ( + )

2x = 292

Divide by two on both sides.

x = 146

The final step is to determine the variable y with the substitution of the value x into one of the two equations above. We choose Equation-1.

x = 146 → 146 + y = 251

y = 251 - 146

y = 105.

Thus, the two numbers are 146 and 105.
