This results in a total distance of 11 kilometers and 149 meters.

The converse of the statement, "If you are smiling, then you are happy" is Option(C) "If you are not smiling, then you are not happy".

The converse of a statement is formed by switching the hypothesis and the conclusion. Thus the converse of a true statement is always false and for conditional relation statement, "If true then yes". If there are two statement proposition p and q then the converse of the statements is denoted as p→q.

Original statement given "If you are smiling, then you are happy" .

Converse is just opposite of the given statement denoting the same meaning of the Hypothesis.

Thus we have the converse statement in Option (C),

"If you are not smiling, then you are not happy".

Answer:

Figure 4: Square

Figure 1: Parallelogram

Figure 2: Rectangle

Step-by-step explanation:

Question 1: If they're not similar it can't be the same shape but if they have the same corresponding angles it has to be either a rectangle or a square. It can't be a rectangle so it must be a square.

Question 2: Can't be similar so it can't be the same shape. The only two shapes with side lengths proportional are the parallelogram and the rectangle. It can't be the rectangle so it must be the parallelogram.

Question 3: If it's similar it has to be the same shape so the answer must be the rectangle.

Answer: April is correct.

Step-by-step explanation: According to the methods used in systems of equations, if we are to solve this system by setting up the equations

(3 = -2x + 1), we see that the solution is x = -1. If you substitute this x-value back into the original equation, y = -2x + 1, we get the answer y = 3 and thus, receiving the solution to the system (-1,3). Anthony is wrong because the graph includes an extra line at x = 3, throwing off his answers.

Answer:

10

Step-by-step explanation:

20%x50=10

Final answer:

To find the number of left-handed players on the sports team, 20% of the 50 total players is calculated, which equals 10 left-handed players.

Explanation:

To calculate the number of left-handed players on a local sports team where 20% of the players are left-handed, you need to apply the percentage to the total number of players. If there are 50 players in total, you would calculate 20% of 50:

Convert the percentage to a decimal by dividing it by 100. So, 20% becomes 0.20.

Multiply this decimal by the total number of players to find the number of left-handed players: 0.20  imes 50 = 10.

Therefore, there are 10 left-handed players on the team.

(x+1)^2 + (y-6)^2 = 3^2

Step-by-step explanation:

The general equation for a circle is given by

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

Substituting in the point (-1,6) and the radius 3

(x--1)^2 + (y-6)^2 = 3^2

(x+1)^2 + (y-6)^2 = 3^2

-6 + 15w = 9w + 66

Answer:

The correct option is B.

Step-by-step explanation:

From the given figure it is clear that triangle LMN is a right angled triangle.

According to Pythagoras theorem: In a right angled triangle

[tex]hypotenuse^2=perpendicular^2+base^2[/tex]

In triangle LMN,

[tex]LN^2=LM^2+MN^2[/tex]

[tex](\sqrt{20})^2=x^2+(x-2)^2[/tex]

[tex]20=x^2+x^2-4x+4[/tex]

[tex]20=2x^2-4x+4[/tex]

Subtract 20 from both sides.

[tex]0=2x^2-4x+4-20[/tex]

[tex]0=2x^2-4x-16[/tex]

Taking out common factors.

[tex]0=2(x^2-2x-8)[/tex]

Splitting the middle term we get

[tex]0=2(x^2-4x+2x-8)[/tex]

[tex]0=2(x(x-4)+2(x-4))[/tex]

[tex]0=2(x-4)(x+2)[/tex]

Using zero product property we get

[tex]x-4=0\Rightarrow x=4[/tex]

[tex]x+2=0\Rightarrow x=-2[/tex]

The value of can not be negative because side of a triangle is always positive. So, the value of x is 4.

Therefore the correct option is B.

Answer: last option.

Step-by-step explanation:

According to the Product of powers property, you have:

[tex]a^n*a^m=a^{(n+m)}[/tex]

As you can see, when you can add the exponents when you have powers with equal base.

Then,  [tex]6^5[/tex]  and [tex]5^{-3}[/tex] do not have the same base, therefore, the exponents can't be added.

Therefore, Eli is incorrect, because he added the exponents even though the bases are not the same.

Answer:

D

Step-by-step explanation:

We will use the radical property  [tex]\sqrt{a*b} =\sqrt{a} \sqrt{b}[/tex]  to simplify this.

The problem is  [tex]\sqrt{169*x^5}[/tex]

We can simplify this as:

[tex]\sqrt{169*x^5} \\=\sqrt{169} \sqrt{x^5}[/tex]

Now we can use the property of radicals,  [tex]\sqrt[n]{x^a} =x^{\frac{a}{n}}[/tex]  , to write as:

[tex]\sqrt{169} \sqrt{x^5} \\13*x^{\frac{5}{2}}[/tex]

D is right answer.

Answer:

d. [tex]13x^{\frac{5}{2}}[/tex]

Step-by-step explanation:

The given expression is

[tex]\sqrt{169x^5}[/tex]

We can rewrite this as

[tex]\sqrt{169}\times \sqrt{x^5}[/tex]

We rewrite as a rational exponent to obtain;

[tex](13^2)^{\frac{1}{2}}\times (x^5)^{\frac{1}{2}}[/tex]

Recall that;

[tex](a^m)^n=a^{mn}[/tex]

[tex]13^{(2\times \frac{1}{2})}\times (x)^{5\times \frac{1}{2}}[/tex]

[tex]13^1 (x)^{\frac{5}{2}}[/tex]

The correct choice is D

[tex]13x^{\frac{5}{2}}[/tex]

Answer: The graph is attached.

Step-by-step explanation:

1. Solve for y, as following:

[tex]10x+7y<49\\7y<-10x+49\\y<-\frac{10}{7}x+\frac{49}{7}\\\\y<-\frac{10}{7}x+7[/tex]

2. The equation of the line in slope intercept form is:

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept.

3. In this case the equation of the line is:

[tex]y=-\frac{10}{7}x+7[/tex]

then:

[tex]m=-\frac{10}{7}\\\\b=7[/tex]

4. Find the x-intercept. Make y=0. Then:

[tex]0=-\frac{10}{7}x+7\\\frac{10}{7}x=7\\x=4.9[/tex]

5. Then, plot the line that passes through the points (0,7) and (4.9, 0).

6. The symbol of the inequality is < therefore, the line must be dashed and indicates that the region under the line must be shaded.

Then you obtain the graph attached.

Answer:

We need to graph the given inequality 10x + 7y < 49.

We can do that into 2 parts:

Part 1:

Graph the line 10x+7y=49

plug any number for x say x=0

10x+7y=49

10(0)+7y=49

0+7y=49

7y=49

y=49/7

y=7

hence it passes through point (0,7)

similarly plug y=0

10x+7(0)=49

10x=49

x=49/10

x=4.9

hence it passes through point (4.9,0)

Graph both points then join them by a straight dotted line because of < sign.

PART 2:

Shade the graph for inequality sign <

use any test point which is not on the given line say (0,0)

plug into original problem

10x + 7y < 49

10(0) + 7(0) < 49

0<49 is true

so shade in direction of test point

Hence final graph looks like:

Answer:

Step-by-step explanation:

Look at the picture.

We know: the sum of the measures of the angles of the triangle is equal to 180 °.

Therefore

In ΔTQR we have the equation:

[tex]\alpha+\beta+130^o=180^o[/tex]         subtract 130° from both sides

[tex]\alpha+\beta=50^o[/tex]

In ΔPQR we have the equation:

[tex]2\alpha+2\beta+m\angle QPR=180^o[/tex]

[tex]2(\alpha+\beta)+m\angle QPR=180^o[/tex]

Substitute from the first equation

[tex]\alpha+\beta=50^o[/tex]

[tex]2(50^o)+m\angle QPR=180^o[/tex]

[tex]100^o+m\angle QPR=180^o[/tex]            subtract 100° from both sides

[tex]m\angle QPR=80^o[/tex]
