The answer is 3,4 what is the question

Answer: The percent of the people surveyed were satisfied with the car = 40% .

Step-by-step explanation:

Given: Total number of people surveyed = 3300

Number of people said that they would buy that type of car again = 1320

i.e. Number of people were satisfied with the car = 1320

The percent of the people surveyed were satisfied with the car =

[tex]=\dfrac{1320}{3300}\times100\\\\=\dfrac{12}{30}\times100\\\\=\dfrac{4}{10}\times100\\\\=0.4\times100=40\%[/tex]

Hence, the percent of the people surveyed were satisfied with the car = 40% .

Answer:

length = 14.14 m and width=width 11.32 m

Step-by-step explanation:

length be L and width be w

L:w = 5:4

L/w = 5/4

Let L =5k and w=4k

since A= lengthxwidth

A=5k x 4k

so, 160 = 20 k2

k 2 = 8

k = 2.828

since L = 5k in above, L= 5x2.828= 14.14

and since w=4k in above, w=4x2.828 = 11.32

This is my Guess. ..

Answer:

I hope it will help u

Step-by-step explanation:

As given that

L:W=5:4

L/W=5/4

hence we also know that

As given A=160m2

putt the value of A and L=(5/4)W in above equation ,

hence      160 = (5/4)W * W

W^2 = 160*4/5

W^2 = 32*4

W^2=128

taking square root

W= +_ 11.3

but length can't be negative so we take positive value of W

Complete Question:

The given line segment has a midpoint at (3, 1). On a coordinate plane, a line goes through (2, 4), (3, 1), and (4, -2).

What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?

Answer:

[tex]y = \frac{1}{3}x[/tex]

Step-by-step explanation:

From the question, we understand that the line goes through [tex](2, 4), (3, 1), and\ (4, -2).[/tex]

First, we calculate the slope of the above points

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (2,4)[/tex]

[tex](x_2,y_2) = (3,1)[/tex]

[tex]m = \frac{1 - 4}{3 - 2}[/tex]

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

[tex]m = -3[/tex]

Also; from the question, we understand that the line segment is perpendicular to the above points.

This slope (m2) of the line segment is calculated as:

[tex]m_2 = -\frac{1}{m}[/tex]

Substitute -3 for m

[tex]m_2 = -\frac{1}{-3}[/tex]

[tex]m_2 = \frac{1}{3}[/tex]

Lastly, we calculate the equation of the line using:

[tex]y - y_1 = m_2(x - x_1)[/tex]

The line segment has a midpoint at (3, 1)

So:

[tex]y - 1 = \frac{1}{3}(x - 3)[/tex]

Open bracket

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

Add 1 to both sides

[tex]y - 1 +1= \frac{1}{3}x - 1+1[/tex]

[tex]y = \frac{1}{3}x[/tex]

Hence, the equation of the line segment is: [tex]y = \frac{1}{3}x[/tex]

The polar form of z is 6√2(cos(135°) + isin(135°)).

Complex numbers are represented in polar form as the complex number's modulus r and argument combined. Given as  z = r cosθ + i r sinθ = r (cosθ + i sinθ).  the polar form of the complex number z = x + iy with coordinates (x, y) is given. Polar coordinates of real and imaginary numbers in the coordinate system are used to express the polar form. A complex number in a two-dimensional coordinate system is  A = x + i y

Given the point z

From the positive real axis, the angle to the point in the second quadrant is calculated (the x-axis). The only options that make sense for the second quadrant are the 135° angles, which fall between 90° and 180°.

The square root of the sum of the squares of z's components determines its magnitude:

|z| = [tex]\sqrt{x^{2} + y^{2} }[/tex]

here x = -6 and y = 6

|z| = √(-6²) + (6²)

z = 6√2

polar form is

z = 6√2(cos(135°) + isin(135°))

Hence the complex form is 6√2(cos(135°) + isin(135°)).

Answer:

Step-by-step explanation:

Side length of a small cube = 6y

Side length of a larger cube = 4x²

This small cube is placed inside a larger cube. We need to find the difference in the  volume of the cubes.

Volume of small cube, [tex]V_1=(6y)^3=216y^3[/tex]

Volume of lager cube,

[tex]V_2=(4x^2)^3\\\\=64x^6[/tex]

Difference in the volume of the cubes,

[tex]\Delta V=V_2-V_1\\\\=64x^6-216y^3[/tex]

We can simplify the above expression :

[tex]\because \ (a^3-b^3)=(a-b)(a^2+ab+b^2)\\\\(4x^2)^3-(6y)^3=(4x^2-6y)((4x^2)^2+4x^2\times 6y +(6y)^2)\\\\=(4x^2-6y)(16x^4+24x^2y+36y^2)[/tex]

So, the difference in the volumes of the cubes is [tex](4x^2-6y)(16x^4+24x^2y+36y^2)[/tex].

Answer:

9:1, 18:2, 27:3, 36:4, 45:5 or 1,2,3,4,5

Step-by-step explanation:

This is the answer because:

1) We can see that eah ratio is being multiplied with the next number. We can say this because 9 x 2 = 18 and 1 x 2 = 2 which is 18:2 just like that 9 x 3 = 27 and 1 x 3 = 3 which makes the ratio 27:3.

2) If we keep on doing this, 9 x 4 = 36 and 1 x 4 = 4 which makes the ratio 36:4.

Therefore, the answer is 4.

Step-by-step explanation:

The total amount of money saved will be 50 - 16c

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given are 4 friends who are buying tickets for a concert. The cost to buy one ticket is c dollars. If you buy all the tickets together, there is a discount and the cost is (5c - 12.5) dollars.

When buyed separately, the total cost = $4c

When bought together, the total cost = $4(5c - 12.5)

Money saved = 4c - 4(5c - 12.5) = 4c - 20c + 50 = 50 - 16c

Therefore, the total amount of money saved will be 50 - 16c

Answer:

141 coins

Step-by-step explanation:

Given that Mark has a total of 380 coins(assumed to be shared amongst Albert,Casey, Lily and Logan)

Albert= x

Casey= 2x

Lily= 2x+5

Logan=3x

There's a total of 380 coins

x+2x+2x+5+3x= 380

8x+5=380

8x=380-5

x=375/8

x= 46.9

Therefore Logan's coins = 3x= 3×46.9= 140.61 coins

Approximately Logan's coins =141 coins
