Answer:

Measure of one of the central angles in the regular pentagon is 72 degree.

Step-by-step explanation:

A Central angle states that the angle made at the center of the polygon by any two adjacent vertices of the polygon.

If you draw a line from any two adjacent vertices to the center, then they would make the central angle.

Since, it is given that the polygon we use here is regular pentagon.

⇒ All the central angles are equal.

The formula to find the central angle is:

Central Angle = [tex]\frac{360^{\circ}}{n}[/tex] where n is the number of sides.

Since, the measure of the central angle thus depends only on the number of sides.

Here, side(n) = 5 (Polygon is regular pentagon)

then;

Central angle = [tex]\frac{360^{\circ}}{5} =72^{\circ}[/tex]

Therefore, the measure of one of the central angle in the regular pentagon is, [tex]72^{\circ}[/tex]

The only multiple choice option that satisfies the above statements is the last one

Answer:

Step-by-step explanation:

Since it's independent you use the formula:

P(A) x P(B) = P(A+B)

(4/5) x P(B) = (1/2)

Make common denominator

(8/10) x P(B) = (5/10)

P(B) = 5/8

If the events are independent, then the value of P(B) will be 5/8.

The chances of an event occurring are defined by probability. Probability has several uses in games, and in business to create probability-based forecasts.

For independent events;

P(A) x P(B) = P(A+B)

(4/5) x P(B) = (1/2)

P(B) =(1/2)×(5/4)

P(B) = 5/8

Hence the value of P(B) will be 5/8.

Answer: A one-to-one correspondence between the parts of two figures is such that the corresponding parts are equal, then the figures are congruent.

The question pertains to geometric concepts of congruence, one-to-one correspondence, included side, included angle, and vector concepts in mathematics, such as orthogonal and parallel vectors, which are key concepts in solving geometry and trigonometry problems.

The question refers to several key concepts in geometry. When each member of a set, such as angles of a triangle, can be paired with one and only one member of another set, we have a one-to-one correspondence. This correspondence can be applied to situations such as pairing angles or sides of one geometric figure with another.

For example, let's consider two triangles. If each angle of the first triangle corresponds to an angle of the second triangle, and all pairs of corresponding elements (angles or sides) are equal, then those two triangles are congruent. This is the basic principle of congruence in geometry.

The angle formed by two sides of a triangle is called an included angle. The side of a triangle that is formed by the common side of two angles is an included side. In a right triangle, like in Figure 5.17, we see the terms adjacent side, opposite side, and hypotenuse, which are used for trigonometric calculations such as sine, cosine, and tangent.

The Pythagorean Theorem plays a crucial role for right-angled triangles, stating that the square on the hypotenuse is equal to the sum of squares on the other two sides. Also, the question talks about parallel and orthogonal vectors. Two vectors are said to be parallel if they have identical directions, while orthogonal vectors are perpendicular to each other, with directions differing by exactly 90°.

Final answer:

After 6 rounds of the chess tournament starting with 1024 players, 16 players will remain. In the story of the king and chessboard with exponential doubling of rice, the total would be [tex]2^{64[/tex] - 1 grains.

Explanation:

To determine how many players will remain after 6 rounds in a chess tournament that starts with 1024 players, we recognize this as a process of successive halving. If each round eliminates half the players, then after each round, the number of players will be:

Therefore, 16 players will remain after 6 rounds in the tournament. Referring to the classic story of the king and the chessboard, when grains of rice are doubled on each square, the final total is one less than [tex]2^{64[/tex] grains. Without adding it all up, we can say this final number is [tex]2^{64[/tex] - 1 grains of rice.

Answer:

12 slats can be made from a board i,e  42 feet long

Step-by-step explanation:

As per the given statement: A fence builder uses boards [tex]3\frac{1}{2}[/tex] feet long for the vertical slats on the fence.

We have to calculate how many slats can be made from a board that is 42 feet long.

Builder uses board [tex]3\frac{1}{2} = \frac{7}{2}[/tex] feet long for the vertical slats.

then;

for 42 feet long = [tex]\frac{42}{\frac{7}{2} } = 42 \times \frac{2}{7} = 6 \times 2 = 12[/tex] slats can be made.

Therefore, 12 slats can be made from a board that is 42 feet long.

Answer:

-5; -40; -640

Step-by-step explanation:

Answer:

The answer is 6.

Step-by-step explanation:

You need to have side x + 4 equal side 3x - 8. If you plug 6 into both equations, then you get x + 4 = 910and 3x - 8 = 10. The last side of the triangle equals 6. You then add all three sides together to get 25. 10 + 10 + 5 = 25.

This is an isosceles triangle (a triangle with 2 congruent/equal sides and 2 congruent angles)

If you look at the triangle, most likely side AB and BC are congruent.

Since the sides are suppose to be the same/equal to each other, you can do this:

AB = BC

x + 4 = 3x - 8       Subtract x on both sides

4 = 2x - 8    Add 8 on both sides

12 = 2x      Divide 2 on both sides

x = 6

You need to find AC.

AC = x, since you know x = 6, side AC is 6 units

Answer:

[tex](y-135)=45(x-3)[/tex]  

Step-by-step explanation:  

Let x represents the number of hours and y represents the number of miles.

We are told that Luz drives at an average speed of 45 miles per hour. She has driven for 3 hours and has traveled a distance of 135 miles.  

We can see from our given information that slope of line is 45 as with each increase in number of hours (x), change in distance (y) is 45.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{135-0}{3-0}[/tex]

[tex]m=\frac{135}{3}[/tex]

[tex]m=45[/tex]

Since the equation of line in point-slope form is : [tex](y-y_1)=m(x-x_1)[/tex], where m represents slope of line and [tex](y_1,x_1)[/tex] represents a point the line passes through.

Upon substituting our given values in point-slope form of equation we will get,

[tex](y-135)=45(x-3)[/tex]  

Therefore, the equation represented in point-slope form will be: [tex](y-135)=45(x-3)[/tex].

Answer:

The slope of the linear equation is  45.

A point on the graph of a linear equation will be (3, 135).

This linear equation can be written as (y-135)=45(x-3).

Final answer:

To find the total amount of juice in all the glasses, add the amounts poured by Maria and Collin. Maria pours 1 ¼ cups of juice and Collin pours 1 ½ cups of juice, so the total amount is 2 ¾ cups.

Explanation:

To find the total amount of juice in all the glasses, we need to add the amounts poured by Maria and Collin. Maria pours 5 glasses of juice, each measuring ¼ of a cup. So Maria pours a total of 5 x ¼ = 1 ¼ cups of juice. Collin pours 6 glasses, also with ¼ of a cup of juice each. So Collin pours a total of 6 x ¼ = 1 ½ cups of juice. To find the total amount of juice in all the glasses, we add 1 ¼ cups and 1 ½ cups, which gives us a total of 2 ¾ cups of juice.

She earns 15% in tips on meals served.

This weekend, Sarah earned $172.50 in all.

Let us assume that the x dollar amount of the meals that Sarah served .

15% is written in the decimal form.

[tex]= \frac{15}{100}[/tex]

= 0.15

Than the equation becomes

x × 0.15 = 172.50

[tex]x = \frac{172.50}{0.15}[/tex]

x = $1150

Therefore $1150  amount of the meals that Sarah served.

Answer:

4 weeks

Step-by-step explanation:

Final answer:

After 5 weeks, you and your friend will have the same amount.

Explanation:

To find out after how many weeks you and your friend will have the same amount, we need to set up an equation and solve for the number of weeks. Let's assume the number of weeks is represented by 'w'.

Your balance in the bank after 'w' weeks can be represented by the expression: 48.50 + 9.50w. Your friend's balance after 'w' weeks can be represented by the expression: 1 + 2(9.50w). We want to find out when these two balances are equal, so we set up the equation: 48.50 + 9.50w = 1 + 19w.

Solving this equation, we get:

48.50 + 9.50w = 1 + 19w

48.50 - 1 = 19w - 9.50w

47.50 = 9.50w

w = 47.50/9.50

w = 5

After 5 weeks, you and your friend will have the same amount.
