Answer:

A. [tex]\frac{3}{10}[/tex] a yard

Step-by-step explanation:

We just need to divide the [tex]\frac{3}{5}[/tex]yard fabric into 2:

[tex]\frac{3}{5}[/tex]÷[tex]\frac{2}{1}[/tex] = [tex]\frac{3}{5}[/tex]×[tex]\frac{1}{2}[/tex]

     = [tex]\frac{3}{10}[/tex]

Answer:

50% will be your answer

Answer:

50%

Step-by-step explanation:

half of 1 whole which is 100% is always 50% or 1/2

Answer:

Step-by-step explanation:

Since area of a circle is pi.r^2

We know that diameter is 20

Radius is half of diameter

So it becomes

Pi.(d/2)^2

So pi.(40/4) is the area of this circle.

Or 40pi/4

Answer:

100π

Step-by-step explanation:

The formula for calculating area of a circle π×r^2 (r: radius)

The given radius here is 20 ÷ 2 = 10

π × 10^2 = 100π

Answer:

0

Step-by-step explanation:

3x^2 + y ( If x = 1, and y = -3)

= 3(1)^2 + (-3)

= 3 + -3

= 0

Answer:

40%

Step-by-step explanation:

Aquí, tuvimos que 5 trabajadores habían terminado el 60% del muro.

Entonces, el porcentaje que queda por hacer sería el porcentaje total, el porcentaje realizado por los 5 trabajadores.

Matemáticamente, el porcentaje total será del 100%.

Entonces, el porcentaje total realizado por los trabajadores restantes será 100% - 60% = 40%

Answer:

R={-24,-20, -16, -4, 8}

Step-by-step explanation:

f(x)=4x-16

f(-2)=4(-2)-16

f(-2)=-8-16

f(-2)=-24

f(x)=4x-16

f(-1)=4(-1)-16

f(-1)=-4-16

f(-1)=-20

f(x)=4x-16

f(0)=4(0)-16

f(0)=0-16

f(0)=-16

f(x)=4x-16

f(3)=4(3)-16

f(3)=12-16

f(3)=-4

f(x)=4x-16

f(6)=4(6)-16

f(6)=24-16

f(6)=8

Answer:

90

Step-by-step explanation:

Just add 35 and 55 it's pretty simple

Step-by-step explanation:

y = -2/3 - 5x

rearranging,

y = -5x -2/3

comparing to the gradient-intercept equation

y = mx + c

m = -5

c = -2/3

Therefore, the slope of the line is -5

Answer: -5

Step-by-step explanation:

Because you know that y=Mx+p right?

So you just take the equation : -2/3-5x and you know that the number before x is m = the slope . Have a nice rest of your day :)

Answer:

Breadth = 35 cm

Length  = 55 cm

Step-by-step explanation:

Breadth : length = 7 : 11

Breadth = 7x

Length  = 11x

Length is 20 cm  more than breadth.

Length = breadth + 20

   11x    = 7x + 20

11x - 7x = 20

      4x = 20

x = 20/4

x = 5

Breadth = 7x  = 7*5 = 35 cm

Length  = 11x  = 11 * 5 = 55 cm

Breadth and length of a rectangle is in the ratio 7:11. Length is 20 cm more than breadth. Find the breadth and length.

In this question we are provided with the ratio of length and breadth 7 : 11 and it is also given that the length of the rectangle is 20 cm more than the breadth and we are asked to find out the length and breadth

Let us assume length as 11x and breadth as 7x.

[tex] \small\underline{\frak{ Length \: is \: 20 \: cm \: more \: than \: breadth}}[/tex]

Length = Breadth +20

According To Question

[tex] \small\bf{ 11x = 7x + 20}[/tex]

[tex] \small\rm{11x - 7x = 20} [/tex]

[tex] \small\rm{4x = 20} [/tex]

[tex] \small\rm{ x = \cancel\dfrac{20}{4} = 5 }[/tex]

[tex]\small\boxed{\rm{x = 5 cm}}[/tex]

Length = 11x = 11 × 5 = 55 cm

Breadth = 7x = 7 × 5 = 35 cm

f(x)=-30

The complex zeros of the polynomials  are 20i and -20i

Given the polynomials, the zeros of the polynomial are gotten by equating the function to zero and then factorizing as shown:

f(x)=x^3−96x^2+400

x^3−96x^2+400 = 0

x^2(x-96) + 400 = 0

x^2(x - 96) = -400

x^2 = -400

Get the required complex roots:

x^2 = -400

x = ±√-400

x = ±20i

Hence the complex zeros of the polynomials  are 20i and -20i

This is a sum of cubes:

x⁶ - 27y³ = (x²)³ + (-3y)³

Recall that

a³ + b³ = (a + b) (a² - ab + b²)

So we have

x⁶ - 27y³ = (x² - 3y) ((x²)² - x² (-3y) + (-3y)²)

x⁶ - 27y³ = (x² - 3y) (x⁴ + 3x²y + 9y²)
