Answer:

1

Step-by-step explanation:

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: D.) A triangle has three congruent sides.

Step-by-step explanation: The first part of a conditional statement is its hypothesis.

Answer:

0

Step-by-step explanation:

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

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

= 3 + -3

= 0

Cheers.

Answer:

Step-by-step explanation:

Putting value of x in the equation

3(5) + 5

= 15 + 5

= 20

Answer:

Luca needs to throw the ball 10 meters to get to Valentina.

Step-by-step explanation:

Distance Between two Points in the Plane

Let's assume Luca is at the origin of coordinates (0,0).

Since Herman is 6 meters south of Luca, he is located at (0,-8).

We also know Herman is 8 meters west of Valentina, or equivalently, Valentina is 8 meters east of Herman. This locates Valentina at (6,-8).

If Luca wanted to throw the ball to Valentina, he would need to cover the distance between them.

Thus the problem reduces to find the distance between (0,0) and (6,-8).

Given two points A(x,y) and B(w,z), the distance between them is:

[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]

Applying the formula:

[tex]d=\sqrt{(-8-0)^2+(6-0)^2}[/tex]

[tex]d=\sqrt{(-8)^2+(6)^2}[/tex]

[tex]d=\sqrt{64+36}=\sqrt{100}=10[/tex]

d=10 m

Luca needs to throw the ball 10 meters to get to Valentina.

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)

Answer:

hello your question is incomplete attached below is the missing table

answer = $48700

Step-by-step explanation:

Calculate the total account receivable in each age category

1) not yet due age category

 = $4000 + $4000 + $7000

 = $15000

2) up to 1 year age category

  = $20500 + $7000

  = $27500

3) more than 1 year age category

  = $6200

therefore the total amount of  account receivables =  15000 + 27500 + 6200  = $48700

Answer:

Ellen will pay $16.22 for the book.

Step-by-step explanation:

Part 1:

We know that the book Ellen wants to buy has a normal price of $18. However, there is a 15% discount. So, let's calculate 15% of $18.

18 x 0.15 = $2.70

This lets us know that there is a $2.70 discount.

Now, let's subtract the discount from the regular price.

18 - 2.70 = $15.30

So, now we know the discounted price is $15.30

Part 2:

We also know that Ellen has to pay 6% sales tax. The discounted price is 100% of the price, plus 6% is 106%. Let's calculate the tax to figure out the total amount.

15.30 x 1.06 = $16.22 when rounded to the nearest cent.

Therefore, Ellen will pay the total amount of $16.22.

Answer:

$16.22

Step-by-step explanation:

marked price        =  $18    = 100%

discount                = $?       = 15%

selling price/         =  $?      = 85%        

discounted price- this price is lower than the marked price as they have given you a DISCOUNT- an amount of money DEDUCTED.(a.k.a selling price)

selling price  =  85%  x   $18     =   $15.3= discounted price

                                 100%

sales tax=6%

=   6 x 15.3     =  0.918 =   $0.92=sales tax

       100

total amount = discounted price + sales tax

                     =  15.3  +  0.92

                      =  $16.22

Answer:David

Step-by-step explanation:

David saves 2:8 = 1;4 is 25%

Laura saves 3/20= 15%

Anna saves 19%

Answer:

Step-by-step explanation:

Step one:

given data

we are told that the discounted price is $7

and the applied discount is 50%

so if 50% of the original price is $7

Step two:

let the original price be x

50/100*x=7

0.5x=7

divide both sides by 0.5

x=7/0.5

x=$14

These means that the original price is $14

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

Step-by-step explanation:

Answer:

Josh sold, 6 computer games, 12 video DVDs, and 11 music CDs

Step-by-step explanation:

The given parameters are;

The number of used discs in the box Josh took to the flea market = 29

The price for which he sold the computer games = $2

The price for which he sold the music CDs = $3

The price for which he sold the video DVDs = $4

The number of DVDs = 2 × The number of computer games

The total amount Josh made = $93

Let C represent the number of computer games and let M represent the number of music CDs, and let V represent the number of DVDs, we have;

We have;

V = 2 × C...(1)

C + M + V = 29...(2)

2 × C + 3 × M + 4 × V = 93...(3)

By substituting the value of V, from equation (1), in equation (2), we have ;

C + M + (2 × C) = 29

∴ 3·C + M = 29

M = 29 - 3·C...(4)

By substituting the value of V, from equation (1) and the value of M, from equation (4) in equation (3), we have;

2 × C + 3 × M + 4 × V = 93...(3)

2·C + 3·M + 4·V = 93

2·C + 3·(29 - 3·C) + 4·(2·C) = 93

2·C + 87 - 9·C + 8·C = 93

C = 93 - 87 = 6

C = 6

The number of computer games = C = 6

V = 2 × C = 2 × 6 = 12

V = 12

The number of video DVDs = V = 12

M = 29 - 3·C = 29 - 3 × 6 = 11

M = 11

The number of music CDs = M = 11

Therefore, Josh sold, 6 computer games, 12 video DVDs, and 11 music CDs.

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%
