A Cinema has 240 seats. 144 seats were sold for the current movie. What percent of seats are empty?

Answer:

x= -74 or -84

Step-by-step explanation:

x^2+3x+37=-7x

x^2+3x+7x+37=0

x^2+10x+37=0

this convert to following

[tex]( - b + - \sqrt{ {b}^{2} } - 4 \times a \times c) \div 2 \times a[/tex]

-b= -(10), a= 1, c =37

according to that

x= -74 or x= -84

Step-by-step explanation:

[tex]\frac{2\sqrt{x}}{c}=y\\\\2\sqrt{x}=cy\\\\\sqrt{x}=\frac{cy}{2}\\\\x=\frac{c^2y^2}{2^2}\\\\x=\frac{cy}{4}[/tex]

Answer:

       c²y²

x = ----------

         4

Step-by-step explanation:

Let's isolate √x:  Multiply both sides of this equation by c/2.  We get:

          c*y

√x = ---------

            2

To find an expression for x, square both sides of this result:

      cy

x = {------ }²

         2

This is equivalent to:

       c²y²

x = ----------

         4

Answer:

The range of the graph is:

-∞ <  y < 2

Hence, option C is correct.

Step-by-step explanation:

We also know that range is the set of values of the dependent variable for which a function is defined.

In other words,

Range refers to all the possible sets of output values on the y-axis.

From the given graph, we can easily observe the vertical extent of the graph is all range values  between -∞ and 2.

In other words,

The range of the function lies in the interval: ( -∞, 2)

Therefore, the range of the graph is:

-∞ <  y < 2

Hence, option C is correct.

Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.

Given that Nolan has 4 times as many pens as Fiona, and Fiona has 6 times as many pencils as Nolan, to determine, if Nolan has a total of 23 pens and pencils, and so does Fiona, the number of pens and pencils that either Nolan or Fiona has, the following calculation must be performed:

Therefore, Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.

Answer:

[tex]\frac{1}{3}[/tex] feet

Step-by-step explanation:

The area of a rectangle is represented by the formula [tex]A = l[/tex] ×[tex]w[/tex], in which [tex]A[/tex] is the area, [tex]l[/tex] is the length, and [tex]w[/tex] is width.

Let's put in what we already know into the formula. We know that the area is [tex]\frac{5}{18}[/tex], so let's substitute that for [tex]A[/tex]. We know that the length is [tex]\frac{5}{6}[/tex], so let's substitute that for [tex]l[/tex]. This gives an equation that looks like this:

[tex]\frac{5}{18} = \frac{5}{6}[/tex] × [tex]w[/tex]

To find the width, all we need to do know is isolate [tex]w[/tex]:

[tex]w = \frac{5}{18}[/tex] × [tex]\frac{6}{5}[/tex]

[tex]w = \frac{30}{90}[/tex]

[tex]w = \frac{1}{3}[/tex]

Thus, the width is [tex]\frac{1}{3}[/tex].

Answer:

y=16 and x=19

Step-by-step explanation:

Let's solve your system by elimination.

−2x+3y=10;10x−9y=46

Multiply the first equation by 5,and multiply the second equation by 1.

5(−2x+3y=10)

1(10x−9y=46)

Becomes:

−10x+15y=50

10x−9y=46

Add these equations to eliminate x:

6y=96

Then solve6y=96for y:

6y=96

6y

6

=

96

6

(Divide both sides by 6)

y=16

Write down an original equation:

−2x+3y=10

Substitute16foryin−2x+3y=10:

−2x+(3)(16)=10

−2x+48=10(Simplify both sides of the equation)

−2x+48+−48=10+−48(Add -48 to both sides)

−2x=−38

−2x

−2

=

−38

−2

(Divide both sides by -2)

x=19

Answer:

x=19 and y=16

The value of x and y on solving a system of linear equations 10x - 9y = 46 and -2x + 3y = 10 by elimination are 19 and 16 respectively.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given equations:

10x - 9y = 46                              (1)

-2x + 3y = 10                             (2)

Multiply equation 2 by 3

3 (-2x + 3y) = 10 × 3  

-6x + 9y  = 30                               (3)

Add equation 3 and equation 1

10x - 9y + (-6x) + 9y = 46 + 30

4x = 76

x = 76 / 4 = 19

Put x = 19 in equation 2

-2 × 19 + 3y = 10

3y = 10 + 38

y = 48 / 3

y = 16

Therefore, the value of x and y on solving a system of linear equations 10x - 9y = 46 and -2x + 3y = 10 by elimination are 19 and 16 respectively.

Answer:

[tex]Ladder = 2\frac{1}{4}\ m[/tex]

Step-by-step explanation:

Given

[tex]Sections = 3[/tex]

[tex]Length = \frac{3}{4}m[/tex] per section

Required

Determine the length of the ladder

The length of the ladder is calculated by multiplying the number of sections by the length of each section.

So, we have:

[tex]Ladder = 3 * \frac{3}{4}\ m[/tex]

[tex]Ladder = \frac{9}{4}\ m[/tex]

[tex]Ladder = 2\frac{1}{4}\ m[/tex]

Hence, the length of the ladder is: [tex]2\frac{1}{4}\ m[/tex] or 2.25m
