Any conditional is of the form "if hypothesis, then conclusion"

=============================

13.

Hypothesis = The ball is red

Conclusion = It (the ball) will bounce higher

=============================

14.

Hypothesis = A plane contains two lines

Conclusion = They (the two lines) are coplanar

=============================

15.

Hypothesis = The light does not come on

Conclusion = The circuit is broken

=============================

16.

Hypothesis = It is cold outside

Conclusion = You must wear your jacket

It might help to rewrite the original sentence as "If it is cold outside, then you must wear your jacket" to have it match up with the "if P, then Q" format (P and Q are the hypothesis and conclusion in that order).

The Hypothesis and Conclusion of each statement are;

13. Hypothesis = The ball is red

Conclusion = It (the ball) will bounce higher

14. Hypothesis = A plane contains two lines

Conclusion = They (the two lines) are coplanar

15. Hypothesis = The light does not come on

Conclusion = The circuit is broken

16.Hypothesis = It is cold outside

Conclusion = You must wear your jacket

What is The Hypothesis and Conclusion?

The conclusion is “then,” part of a conditional statement.

The hypothesis is the “if,” part of a conditional statement

Now,

To find the hypothesis and conclusion of each statement we can change any conditional is of the form "if hypothesis, then conclusion"

The first statement is;

13.  If the ball is red, then it will bounce higher.

In form of the hypothesis and conclusion written as;

⇒ Hypothesis = The ball is red

Conclusion = It (the ball) will bounce higher

And, The second statement is;

14. If a plane contains two lines, then they are coplanar.

In form of the hypothesis and conclusion written as;

⇒ Hypothesis = A plane contains two lines

Conclusion = They (the two lines) are coplanar.

And, Third statement is;

15. If the light does not come on, then the circuit is broken.

In form of the hypothesis and conclusion written as;

⇒ Hypothesis = The light does not come on

Conclusion = The circuit is broken.

And, Fourth statement is;

16. You must wear your jacket if it is cold outside.

In form of the hypothesis and conclusion written as;

⇒ Hypothesis = It is cold outside

Conclusion = You must wear your jacket

Step-by-step explanation:

i just did it on edge

C is correct.

Equation: t = 25 + 8.25w, where w is the number of weeks and t is the total Aaliyah saved.

What is the error that occurred when Aaliyah completed her table? The ordered pair (132.25, 13) should be (13,  132.25).

9^c = 243

3^(c)*2 = 243

3^(c)*2 = 3^5

Since the bases are the same the powers can be equated.

2*c =5

c = 5/2

c = 2 1/2

Check

9^2.5 = 243

Answer:

[tex]BD = 19[/tex]

Step-by-step explanation:

Given

[tex]CD = 2x[/tex]

[tex]BD = 3x + 4[/tex]

[tex]BC = 2x -1[/tex]

Required

Find BD

Since C is on BD, we have:

[tex]BD = BC + CD[/tex]

Substitute values for BD, BC and Cd

[tex]3x + 4 = 2x - 1 + 2x[/tex]

Collect Like Terms

[tex]3x - 2x - 2x = -1 - 4[/tex]

[tex]-x = -5[/tex]

Multiply through by -1

[tex]x = 5[/tex]

Substitute 5 for x in [tex]BD = 3x + 4[/tex]

[tex]BD = 3 * 5 + 4[/tex]

[tex]BD = 19[/tex]

Answer:

Q1: is 0

Q2: is 20

Step-by-step explanation:

Q1: Divide the numbers 0 ÷ 6 = 0

√8 × 0

√8 = 2√2

2 × 0 × √2

Apply rule 0 × a = 0

Q2: Apply exponent rule : (a × b)^n = a^n b^n

2^2(√5)^2 = 2^2 (√5)^2

2^2 = 4

4 (√5)2

(√5)^2 = 5

4 × 5

Multiply the numbers: 4 × 5 = 20

8.15 is a rational number

Answer:

17

Step-by-step explanation:

m<1 = (4x + 2)

m<3 = (5x - 15)

To find the value of x, we need to generate an equation.

<1 and <3 are vertical angles. Vertical angles are congruent. Therefore:

m<1 = m<3

(4x + 2) = (5x - 15)

Use this equation to solve for x

4x + 2 = 5x - 15

Subtract 5x from both sides

4x + 2 - 5x = 5x - 15 - 5x

-x + 2 = -15

Subtract 2 from both sides

-x + 2 - 2 = -15 - 2

-x = -17

Divide both sides by -1

x = 17
