Table 4 is showing proportional relationship between weight and price.

What is proportionality?

The number or amount of a group or part of something when compared to the whole, is considered as proportionality.

Given that, a table of proportional relationship between weight and price;

If we consider table number 4,

We see, weight : price = 2 : 4 = 1 : 2

And, 4 : 8 = 1 : 2

Therefore, this is showing proportionality,

Hence, Table 4 is showing proportional relationship between weight and price.

Answer:

when

[tex]x\ge 0[/tex]

then

[tex]x\times \left|x\right|=x^{2}[/tex]

Step-by-step explanation:

As we know that

When x is positive

[tex]\left|x\right|=\:x[/tex]

As from the question,

[tex]x\ge 0[/tex]

so the expression will be:

[tex]x\times \left|x\right|=x\times x=x^2[/tex] ∵ [tex]x\ge 0[/tex] so [tex]\left|x\right|=\:x[/tex]

Therefore,

Step-by-step explanation: just had this on the test

The correct expression for the expansion of 72.603 is 7 x 10 + 2 x 1 + 6 x 1/10 + 3 x 1/1000 (option 3rd)

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is a decimal number, 72.603

On expanding it, we get,

72.603 = 72 + 0.603

= 7 x 10 + 2 x 1 + 6 x 1/10 + 3 x 1/1000

Hence, the correct expression for the expansion of 72.603 is 7 x 10 + 2 x 1 + 6 x 1/10 + 3 x 1/1000

1. If OQ and RT are parallel lines which statement is true?

A) OPS is congruent to RSU

B) OPS is congruent to RSP (my answer)

C) OPS is congruent to OPN

D) OPS is congruent to TSU

-----------------------------------------

2. If OQ and RT are parallel lines which statement is true?

A) RSP is congruent to RSU

B) RSP is congruent to PST

C) RSP is congruent to TSU

D) RSP is congruent to OPS (my answer)

Answers

Answer:

Step-by-step explanation:

Question (1).

OQ and RT are the parallel lines and UN is a transversal intersecting these lines at two different points P and S.

A). ∠OPS ≅ ∠RSU [corresponding angles]

B). m∠OPS + m∠RSP = 180° [Consecutive interior angles]

C). m∠OPS + m∠OPN = 180° [Linear pair of angles]

D). Since, ∠OPS ≅ ∠TSP [Alternate interior angles]

And m∠TSP + m∠TSU = 180° [Linear pair of angles]

Therefore, Option (A) is the correct option.

Question (2).

A). m∠RSP + m∠RSU = 180° [Linear pair of angles]

B). m∠RSP + m∠PST = 180° [Linear pair of angles]

C). ∠RSP ≅ ∠TSU [Vertically opposite angles]

D). m∠RSP + m∠OPS = 180° [Consecutive interior angles]

Therefore, Option (C) will be the answer.

Answer:

Step-by-step explanation:

OQ and RT are parallel lines, while UN is a transversal that crosses both lines at two points. P and S are a couple.

A). RSU [corresponding angles] OPS

B). [Consecutive interior angles] mOPS + mRSP = 180°

C). [Linear pair of angles] mOPS + mOPN = 180°

D.) Since then, OPS TSP [Alternate Interior Angles] has been implemented.

And [Linear pair of angles] mTSP + mTSU = 180°

As a result, Option (A) is the right one.

Inquiry (2).

A). [Linear pair of angles] mRSP + mRSU = 180°

B). [Linear pair of angles] mRSP + mPST = 180°

C). [Vertically opposite angles] RSP TSU

D). [Consecutive interior angles] mRSP + mOPS = 180°

so it’s gonna have to be C
