Answer:

$given \: that \: the \: cost \: of \: orchestra \: is \: three \: times \: of \: balcony \: ticket \\ let \: the \:cost \: of \: balcony \: \: ticket \: be \:x \\ so \: the \: cost \: of \: orchestra \: ticket \: sold \: be \: 3x \\ the \: total \: income = 3640 \\ \\ so \: the \: equation \: formed \: = > 148(3x)+ 76(x) = 3640 \\ = > 444x + 76x = 3640 \\ = > 520x = 3640 \\ = > x = \frac{3640}{520} \\ = > x = 7$

$so \: orchestra \: ticket \: = 444x = 444 \times = 3108 \\ and \: balcony \: ticket \: = 76x = 76 \times 7 = 532$

FOR PROOF = 3108+532 = 3640 total income

A rectangle is 64 cm long 40 cm wide find is area and perimeter

kow [346]

Answer:

Assuming the length to be x and the width to be y.

Since the area is 64cm, hence

x*y = 64 (equation 1)

Since the perimeter is 40cm, hence

x + x + y + y = 40

2x + 2y = 40

2(x + y) = 2(20)

x + y = 20 (equation 2)

Hence by using simultaneous equation,

x = 20 - y (equation 3)

Substituting equation 3 into equation 1, we get

(20-y)*y=64

20y-y^2=64

Tidying up the equation,

y^2 - 20y + 64 = 0

By using factorisation,

(y-16)(y-4)=0

y=16 or y=4

By substituting y=16 into equation 1,

x*16=64

x = 4

By substituting y = 4 into equation 1,

x*4=64

x=16

Therefore,

The length is 4 cm while the width is 16 cm.

The length is 16 cm while the width is 4cm.

Write the equation of a line perpendicular to y=-12x+2 going through (0,-1)

DanielleElmas [232]

$\rule{50}{1}\large\blue\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}$

<em>Write the equation of a line perpendicular to y=-12x+2 going </em>

<em> through (0, -1)</em>

<em />

<em> </em> $\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}$

First, let's take a look at our provided information:-

A line $\text{y=-12x+2}$
A point (0, -1)
The line $\text{y=-12x+2}$ is perpendicular to the line that goes through (0, -1)

If two lines are perpendicular to each other, their slopes are opposite reciprocals of each other.

So we take the slope of the given line, which is -12, change its sign from minus to plus:-

$\Large\textit{12}$

And now, We flip the number over:-

$\Large\text{$\displaystyle\frac{1}{12}$}$

Now that we've found the slope of the line, let's find its equation.

The first step is to write it in point-slope form as follows:-

$\longmapsto\sf{y-y_1=m(x-x_1)}$

Replace letters with numbers,

$\longmapsto\sf{y-(-1)=\displaystyle\frac{1}{12}(x-0)}$

On simplification,

$\longmapsto\sf{y+1=\displaystyle\frac{1}{12} (x-0)}$

On further simplification,

$\longmapsto\sf{y+1=\displaystyle\frac{1}{12} x}$

Subtracting 1 on both sides,

$\longmapsto\sf{y=\displaystyle\frac{1}{12} x-1}$

How do i check 1/3v=-5 ?

BigorU [14]

If you mean that you want to solve the equation for v, then all you need to do is to multiply both sides by 3:

$\dfrac{1}{3}v=-5 \iff 3\cdot \dfrac{1}{3}v = -5\cdot 3 \iff v=-15$
