First, we have to set a number line:

We can see, that of we move left to right, 12 is greater than -29.

SO:

12 > -29

2) AE is congruent to ED, BE is congruent to ED (a bisector splits a segment into two congruent parts)

3) Angle AEB is congruent to angle DEC (vertical angles are congruent)

4) Triangle ABE is congruent to triangle CDE (SAS)

The area of the regular polygon is 536.35 inches².

The polygon above is an heptagon. An heptagon is a polygon with 7 sides. The area of the regular polygon can be found as follows:

area of the polygon = n(1 / 2r²sin(central angle))

central angle of an heptagon = 51.43 degrees

r = 14 inches

n = 7

Therefore,

area of the polygon = 7(1 / 2 × 14² × sin 51.43)

area of the polygon = 7 (196 / 2 sin 51.43)

area of the polygon = 7(98 × 0.78184702786)

area of the polygon = 7 × 76.621008731

area of the polygon = 536.347061117

Therefore,

area of the regular polygon = 536.35 inches²

Answer:

$120

Step-by-step explanation:

40% off means that the post reduction price is 60% of the original.

Therefore, if $45 is 60% of the original,

100% of the original price = 45 / 60 x 100 = $75

Therefore, the total cost of both = 45 + 75 = 120

Answer:

72 degrees

Step-by-step explanation:

A pentagon has five lines of symmetry. For rotation symmetry, the order of any regular polygon is the number of sides. The angle of rotation would be 360 degrees divided by that order. Therefore, the answer is 72 degrees.

Answer:

in scientific is: 7.283×10^-1

Step-by-step explanation:

Possible answers to the expression 2x - 15 are given as follows:

An expression is solved isolating the variable of which we want to find the value.

In this problem, the expression is given as follows:

2x - 15 = c.

In which c is a constant that is not given in the incomplete problem here, hence we will attribute values to it.

With c = -35, we have that the solution is found as follows:

2x - 15 = -35

2x = -20 (-35 + 15)

x = -20/2

x = -10.

Now, if c = 3, the solution is calculated as follows:

2x - 15 = 3

2x = 18

x = 18/2

x = 9.

In your problem, a value for c(the right-handed side of the equality) will be given, and you will solve it applying the same procedure I applied in the answer here.

37.1 degrees Celsius is equivalent to 98.78 degrees Fahrenheit. both are unit of measurement of Temperature

To convert Celsius (C) to Fahrenheit (F), you can use the conversion formula: (C x 9/5) + 32 = F. So to convert 37.1 degrees Celsius to Fahrenheit, you would multiply 37.1 by 9/5, then add 32 which is equivalent to 98.78 degrees Fahrenheit.

It's worth noting that Fahrenheit  scale commonly used in the United States, while Celsius is the standard temperature scale in the International System of Units (SI) and widely used across the world.

Solving for p(u ∩ v) using the given equation p(u' ∪ v') = 0.3, we find that p(u ∩ v) is equal to 0.7.

To solve for p(u ∩ v) using the given information, we can start by recognizing that u' represents the complement of u (the event that is not u), and v' represents the complement of v (the event that is not v).

Using De Morgan's law, we can rewrite p(u' ∪ v') as p((u ∩ v)'):

p((u ∩ v)') = 0.3

Now, let's consider the complement of (u ∩ v), which is (u ∩ v)'. According to the complement rule, the probability of an event and its complement adds up to 1. Therefore, we have:

p((u ∩ v)) + p((u ∩ v)') = 1

Substituting the value of p((u ∩ v)') from the given equation, we get:

p(u ∩ v) + 0.3 = 1

Rearranging the equation, we find:

p(u ∩ v) = 1 - 0.3

p(u ∩ v) = 0.7

Answer:

A cylinder.

Step-by-step explanation:

A cylinder has two round tops , and one long body shape. When you roll the rectangle, it creates the body shape of the cylinder and the circles are the tops.

The multiplicative rate of change of the exponential function represented in the table is 5.

To determine the multiplicative rate of change of the exponential function, we can examine the relationship between the entries in the y-column and the corresponding entries in the x-column.

Looking at the values in the y-column, we can observe that each subsequent value is obtained by multiplying the previous value by a constant factor. For example, 4.5 divided by 4 is 1.125, which is approximately 5/4. Similarly, 6.75 divided by 4.5 is approximately 5/3, and so on.

This pattern indicates that the multiplicative rate of change between consecutive entries in the y-column is 5/4. In other words, each value in the y-column is obtained by multiplying the previous value by 5/4. This consistent ratio of 5/4 represents the multiplicative rate of change of the exponential function.

Therefore, the correct answer is option 1: 5.

El punto A(-3, 3) pertenece a la recta.

El punto B(0, -15) no pertence a la recta.

Explicación paso a paso:

Consideremos la siguiente ecuación de la recta en forma estandar.

-4x - y + 15 = 0

Para verificar si los puntos A y B pertencen a la recta, primero la transformaremos a la forma explícita.

-4x - y + 15 = 0

-4x + 15 = y

y = -4x + 15

El punto A(-3, 3), tiene coordenada x -3 y coordenada y 3. Reemplazaremos x en la ecuación de la recta y veremos si obtenemos el mismo valor de y.

y = -4(-3) + 15 = 3

El punto A(-3, 3) pertenece a la recta.

El punto B(0, -15), tiene coordenada x 0 y coordenada y -15. Reemplazaremos x en la ecuación de la recta y veremos si obtenemos el mismo valor de y.

y = -4(0) + 15 = 15

El punto B(0, -15) no pertence a la recta.

When chosen 2 of the 16,701 mathematics degrees at random, the probability that at least 1 of the 2 degrees was earned by a woman is P(at least 1 women out of 2)= 70.4064%

P(women)=0.4560

We know the rule: P(not A) = 1−P(A)

We can then determine the probability of individuals who earned a degree but are not women:

P(not women) =1−P(women)=1−0.4560=0.5440

when we multiply we get,

P(A and B) = P(A)×P(B)

now we can then determine the probability of obtaining 2 individuals who earned a degree but are not women:

P(2 not women) = P(not women) × P(not women)

= 0.5440 × 0.5440 = 0.295936

now we can use the complement rule, and with this now we can then determine the probability of at least 1 degree earned by women:

P(at least 1 women out of 2) = 1−P(2 not women) = 1−0.295936

=0.704064

=70.4064%

The  proportion to estimate the number of seventh graders, n, who participate in the contest.  

a . 10/25 = x/480

b. 192 seventh graders participate in the contest.

c.  288 seventh graders do not participate in the contest.

a. We can write a proportion to estimate the number of seventh graders, n, who participate in the contest as:

10/25 = x/480

where x is the unknown number of seventh graders who participate in the contest.

b. To solve the proportion, we can cross-multiply to get:

10 * 480 = 25 * x

Simplifying the right-hand side:

4800 = 25x

Dividing both sides by 25, we get:

x = 192

Therefore, we estimate that 192 seventh graders participate in the contest.

c. We can write a proportion to estimate the number of seventh graders, n, who do not participate in the contest as:

(25-10)/25 = y/480

where:

y is the unknown number of seventh graders who do not participate in the contest.

Simplifying the left-hand side:

15/25 = y/480

Cross-multiplying:

15 * 480 = 25 * y

Simplifying the left-hand side:

7200 = 25y

Dividing both sides by 25:

y = 288

Therefore, we estimate that 288 seventh graders do not participate in the contest.

The total surface area of the block is 32.6 square inches.

Given that, Jake has a block shaped like the prism shown in a set of toys.

To find the surface area of any kind of prism we use the general formula. The total surface area of a prism is the sum of lateral surface area and area of two flat bases.

The total surface area of a prism = (2 × Base Area) + (Base perimeter × L).

Here, area = 2 ×1/2×2×2.3 +(2+2.5+2.5)×4
