The proportional relationship between the number of centerpieces and the total cost for the centerpieces is graphed at the end of the answer.

A graph represents a proportional relationship if the output variable y in the y-axis is written as a product of the input variable x in the x-axis and the constant of proportionality k, as follows:

y = kx.

The constant k is called the slope of the unit rate of the situation, measuring by how much y changes when x changes by 1.

In the context of this problem, the cost of each centerpiece is of $5.50, hence the constant is given as follows:

y = 5.5x.

The number of centerpieces cannot be negative, hence the domain of the relation is given as follows:

x ≥ 0.

Considering this domain, the graph of the relation is given at the end of the answer.

Answer: 63.30769 or 823/13 or 63 4/13

823 divided by 13 = 63.307692

The result of 823/13 is a non-terminating, repeating decimal.

The repeating pattern above, 307692, is called repetend, and denoted overlined with a vinculum.

This notation in parentheses is also common: 823/13 = 63.(307692): However, in daily use it’s likely you come across the reptend indicated as ellipsis: 823 / 13 = 63.307692… .

823 divided by 13 in decimal = 63.307692

823 divided by 13 in fraction = 823/13

823 divided by 13 in percentage = 6330.76923077%

Answer:

x + 2y = 5

Step-by-step explanation:

y = mx + b the m is the slope or gradient.  

y=2x+3  The slope is 2.

When lines are perpendicular,  the slopes are opposite inverses of each other.  So, the perpendicular slope to 2 is -1/2.  I would write the answer in the point slope of the line and then change the equation to the stand form

y -2 = -1/2(x -1)  Distribute the -1/2

y - 2 = -1/2x + 1/2  Add 1/2 x to both sides

1/2x + y -2 = 1/2  Add 2 to both sides

1/2x +y = 5/2  Multiply by 2 to clear the decimal

x + 2y = 5

Given equation:

[tex]\dfrac{1}{3}x-\dfrac{2}{5}y=-4[/tex]

[tex]\textsf{Add \;$\dfrac{2}{5}y$ \; to both sides}:[/tex]

[tex]\implies \dfrac{1}{3}x-\dfrac{2}{5}y+\dfrac{2}{5}y=-4+\dfrac{2}{5}y[/tex]

[tex]\implies \dfrac{1}{3}x=\dfrac{2}{5}y-4[/tex]

Add 4 to both sides:

[tex]\implies \dfrac{1}{3}x+4=\dfrac{2}{5}y-4+4[/tex]

[tex]\implies \dfrac{1}{3}x+4=\dfrac{2}{5}y[/tex]

[tex]\textsf{Multiply both sides by \; $\dfrac{5}{2}$}:[/tex]

See the attachment for the highlighted mistake.

The mistake Mike made is that he did not divide 10x by 3.

Add 3y to both sides:

[tex]\implies 10x=6+3y[/tex]

Subtract 6 from both sides:

[tex]\implies 10x-6=6+3y-6[/tex]

The x-intercepts of the function are 10, and -8.

y-intercept is: -80.

The zeros are: x = 10 and x = -8

f(2) = -80

f(x) = -65 when x = 5 or -3.

The y-intercept of a function is the output (y) when the input value (x) is zero. On the other hand, the x-intercept is the input value (x), when the output value (y) is zero.

The zeros of a function are the x-intercepts of a function.

Given the function, f(x) = x² - 2x - 80, substitute f(x) = 0 to find the value of x, which is the x-intercept:

0 = x² - 2x - 80

x² - 2x - 80 = 0

Factorize

(x - 10)(x + 8)

x = 10 or x = -8

Substitute x = 0 into the function to find the y-intercept:

f(0) = 0² - 2(0) - 80

f(0) = -80

x-intercepts are 10, and -8.

y-intercept is: -80.

The zeros are: x = 10 and x = -8

Find f(2):

f(2) = (2²) - 2(2) - 80,

f(2) = 4 - 4 - 80

f(2) = -80

Find x when f(x) = -65:

-65 = x² - 2x - 80

-65 + 80 = x² - 2x

15 = x² - 2x

x² - 2x  - 15 = 0

Factorize

(x - 5)(x + 3) = 0

x = 5; x = -3

Therefore, f(x) = -65 when x = 5 or -3.

Answer:

m∠R = 72°

Step-by-step explanation:

As ΔPQR and ΔUVW are congruent, m∠R = m∠W.

Equate the expressions for the two angles and solve for x:

⇒ m∠R = m∠W

⇒ 10x - 18 = 8x

⇒ 10x - 18 + 18 = 8x + 18

⇒ 10x = 8x + 18

⇒ 10x - 8x = 8x + 18 - 8x

⇒ 2x = 18

⇒ 2x ÷ 2 = 18 ÷ 2

⇒ x = 9

Substitute the found value of x into the expression for m∠R:

⇒ m∠R = 10x - 18

⇒ m∠R = 10(9) - 18

⇒ m∠R = 90 - 18

⇒ m∠R = 72°

Therefore, m∠R = 72°.

The method that can not be used to prove that lines i and k are parallel is the statement "shows that both lines are perpendicular to a third line".

Lines l and k intersect forming two pairs of vertical angles. If one of these angles measures 120°,

As per the given question,

Let angle ∠1 is 120°

here angles ∠1 and ∠2 are supplementary

So  ∠2 = 180° - 120° = 60°

However, if a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.

∠2 = ∠4 = 60°

The equation to represent the cost of each drink is 3(x + 2.5) + 3x = 25.50. The cost of each drink will be $3.

In the given question, it is stated that the family spent a total of $25.50 and they bought 3 Popcorn and 3 Drinks. Each popcorn costs $2.5 more than the drink. Now, suppose the cost of one drink is 'x' then we get:

Cost of 3 Drinks = 3x

Cost of 3 Popcorn = 3(x + 2.5)

The equation to represent this will be:

=>  3(x + 2.5) + 3x = 25.50

=>  3x + 7.5 + 3x = 25.50

=>  6x = 18

=>  x = 3

We get x = 3, Cost of one drink will be $3

Hence,  equation representing it will be 3(x + 2.5) + 3x = 25.50, and the cost of each drink will be $3

The strategy used by Dr. Chang for the research study of undergraduate students is c. stratified sampling.

Stratified sampling can be defined as the type of sampling in which a population is divided into subpopulations and then random samples are taken from these subpopulations. These subpopulations or subgroups are also called strata.

The strategy used by Dr. Chang is stratified sampling because she divided all the undergraduate students into subgroups based on grade level and then from these subgroups she randomly selected 50 students.

Contrastingly, in simple random sampling, no subgroups are involved and the subset of individuals are chosen from a single large population randomly. On the other hand, quota sampling and accidental sampling are not a type of random sampling.

In cluster sampling, the subgroups are internally heterogeneous but in this case, the subgroups are internally homogenous as they are made based on grade level.

A force of 85 N is applied over an area of 530 cm2. Then the pressure on it is equal to 1603.8 [tex]\frac{N}{m^{2} }[/tex].

Force(F) = 85 N

Area(A) = 530 [tex]cm^{2}[/tex]

Pressure(P) = ?

Calculating as per the above amount

Area = 530/100 × 100

= 0.053 [tex]m^{2}[/tex]

The definition of pressure is "force applied per unit area." The equation P = FA, where F is the force acting perpendicular to surface area A, provides the answer. The pascal (Pa), or one newton per square meter, is the accepted unit of pressure [tex]\frac{N}{m^{2} }[/tex].

Pressure is the physical amount of force exerted on a particular area. The definition of pressure is "force per unit of area." The pressure being applied to a body can be calculated by taking the amount of force being applied and dividing it by the area of contact.

Pressure = force/area
