The formula for perimeter is length + length + width + width

You know that all the sides of a square are equal to each other. That means that all the values in the perimeter formula should be the same. Therefore you can divide 72 by 4 (perimeter divided by the number of sides)

72 / 4 = 18

^^^Each side is 18 in

The formula for are is...

A = length x width

so...

18 * 18 = 324

324 in^2

Answer:

-2/3x = 1/4

x = (1/4)(-3/2)

x = -3/8

Answer:

Answer is D: 9

Step-by-step explanation:

you would do 2x-6=12

Next: add 6 to both sides: 2X=18

Next: divide both sides by 2

Answer: X=9

Given that Benjamin's age is 6 years less than twice Lucas's age and Benjamin is 12 years old.

Let x and y represent Luca's age and Benjamin's age respectively.

Then, according to the given information, we have

y = 2x-6⇒1

y=12      ⇒2

Substituting the value of y from equation (2) in (1), we get

y=2x-6

⇒12=2x-6

⇒2x=12+6

⇒2x=18

⇒x=18/2

∴ x=9

Lucas's age is Option D. 9

Thus, the required age for Luca is 9 years.

The slope of the line shown in the graph is -2.

The slope of a line can be found using the formula slope = (change in y) / (change in x).

Given the points (0, 3) and (1, 1),

we can calculate the slope by finding the difference in y-coordinates and dividing it by the difference in x-coordinates.

Slope = (1 - 3) / (1 - 0) = -2.

Answer:

y = 3x + 1

Step-by-step explanation:

The equation is in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (1, 4) ← 2 ordered pairs from table

m = [tex]\frac{4-1}{1-0}[/tex] = 3

Note the line crosses the y- axis at (0, 1) ⇒ c = 1

Step-by-step explanation:

To find the lower quartile first locate the median.

The median is the middle value of the data set arranged in ascending order.

The data given is in ascending order

0, 1, 3, 3, 4, 4, 4, 5, 6, 6, 8

                    ↑ ← The median is 4

The lower quartile is then the middle value of the data to the left of the median.

0, 1, 3, 3, 4

       ↑ ← the lower quartile is 3

The lower quartile of the data is given as 3

Lower quartile of the data is the median of all the observations till the median of the given observations.

Median is the middle observations of the set of observations.

The median is the mid value which is 4

So, the values till 4 are 0, 1 , 3, 3, 4,

∴  The median is the mid value which are 3

Answer:

Since AB = BE and DB =CE

Step-by-step explanation:

The ratio and of these two give the concept of slope

The last sentence explains why the slope of AB is equal to slope of BC.

It is the measure of steepness of a line.

In the given figure, AD = BE and DB = EC

So, the ratio AD to BE is equal to the ratio BE to EC.

The slope of a line is given by,

slope = rise / run

Which is same as the above mentioned ratio.

Since AD = BE and DB = EC, their proportions are also equal. Therefore the slope of AB is equal to the slope of BC.

Answer:

The correct answers are:

(1) The vertical asymptote is x = 0

(2) The horizontal asymptote is y = 0

Step-by-step explanation:

(1) To find the vertical asymptote, put the denominator of the rational function equals to zero.

Rational Function = g(x) = 

Denominator = x = 0

Hence the vertical asymptote is x = 0.

(2) To find the horizontal asymptote, check the power of x in numerator against the power of x in denominator as follows:

Given function = g(x) = 

We can write it as:

g(x) = 

If power of x in numerator is less than the power of x in denominator, then the horizontal asymptote will be y=0.

If power of x in numerator is equal to the power of x in denominator, then the horizontal asymptote will be y=(co-efficient in numerator)/(co-efficient in denominator).

If power of x in numerator is greater than the power of x in denominator, then there will be no horizontal asymptote.

In above case, 0 < 1, therefore, the horizontal asymptote is y =

Answer:

Step-by-step explanation:

If the line has no x-intercept, then it's a horizontal line with equation

[tex]y=a,\ a\neq0[/tex]

The line passes through the point (0, -4). Therefore the equation of this line is:

[tex]y=-4[/tex]

Answer:

y = 4

Step-by-step explanation:

Since the line has no x-intercept, this means that the line has a slope of 0, meaning it is a horizontal line. So with the equation y = mx + b, mx cancels out to 0 because there is no slope. This leaves y = b, where b = 4. So the answer is y =4

Answer:

Step-by-step explanation:

There are 5 cards we are selecting out of 135 cards so how many ways can we draw 5 cards at a time (w/o replacement)

There are 135 ways to choose the first card.

There are then 134 ways to choose the second card.

There are then 133 ways to choose the third card.

132 to choose the 4th

131 to choose the 5th.

Now multiply those giving 135*134*133*132*131 or you could have just said

135 P 5.

In case you don't know P means permutation.

The mathematics behind determining the number of different ways to get any 5 card hand from a deck of 135 cards involves combinatorics. Specifically, the combinations formula is used, which is C(n, r) = n! / [(n-r)!r!]. In this case, n is 135 (the total number of cards) and r is 5 (the number of cards drawn).

The subject of this question concerns probabilities in the game theory section of mathematics, specifically revolving around understanding the combinatorics of card hands in a uniquely structured card game.

Using combinatorial mathematics, the number of ways to get any 5-card hand from a deck of 135 cards can be calculated by using the combinations formula which is: C(n, r) = n! / [(n-r)!r!]. In this instance, 'n' represents the number of total outcomes (135 cards) and 'r' is the number of outcomes chosen at a time (5 cards).

So to find the number of 5-card hands, you would calculate it as follows:

C(135, 5) = 135! / [(135-5)!5!]

The factorial of a number, denoted as '!', is the product of the number and all the consecutive numbers below it down to 1. So 5! = 5*4*3*2*1. Calculating this large of a number directly can be a bit tricky, but there are online tools that can help!

Answer:

y = [tex]\frac{1}{27}[/tex]

Step-by-step explanation:

Given

y = [tex]3^{x}[/tex] and (- 3, y) is a point on the graph, then

y = [tex]3^{-3}[/tex] = [tex]\frac{1}{3^{3} }[/tex] = [tex]\frac{1}{27}[/tex]

Answer:  The required value of y is [tex]\dfrac{1}{27}.[/tex]

Step-by-step explanation:  We are given that the point (-3, y) lies on the graph of the following equation :

[tex]y=3^x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We are to find the value of y.

Since the point (-3, y) lies on the graph of equation (i), so it will satisfy the equation.

Therefore, substituting (-3, y) in equation (i), we get

[tex]y=3^{-3}\\\\\Rightarrow y=\dfrac{1}{3^3}\\\\\\\Rightarrow y=\dfrac{1}{27}.[/tex]

Thus, the required value of y is [tex]\dfrac{1}{27}.[/tex]

m angle BOC 120

m angle AOB 205

Step-by-step explanation:

So you are given mangle AOC+mangle BOC=mangle AOB.

mangle means measure of angle.

Let's do some substituting into our equation.

85+2x+10=4x-15

Solve for x... First I'm going to combine the like terms on the left hand side:

95+2x=4x-15

Add 15 on both sides

110+2x=4x

Subtract 2x on both sides

110     =2x

Divide both sides by 2

110/2   =x

x         =110/2

x          =55

So Recall mangle BOC=2x+10   =2(55)+10=110+10=120

And you also have mangle AOB=4x-15=4(55)-15=220-15=205

Answer:

y = (1/3)x

Step-by-step explanation:

If the y-intercept is (0, 0), then y = mx + b becomes y = mx.

Seeing that y increases by 1, going from (-3, 1) to (0, 0), and that x increases by 3, we determine that the slope, m, is 1/3.

The equation of this line is therefore y = (1/3)x.

The other x-intercept is (-2,0)

Step-by-step explanation:

-(x+3)(        )

The other factor has to be x+2 since 3(2)=6 and 2+3=5

So -x^2-5x-6 is the same as -(x+3)(x+2)

Which means the other x-intercept is (-2,0)
