Answer:

13.5 euros

Step-by-step explanation:

A partir de la pregunta anterior, las dimensiones del terreno se dieron como 0.3 & 0.9 m

El terreno es de forma rectangular.

Paso 1

Encontramos el área de la tierra

Área = Largo × Ancho

Área = 0.3 m × 0.9 m

Superficie = 0.27m²

Paso 2

Nos dijeron

1 m² = 50 euros

0.27m² = x

Multiplicar cruzada

x = 0.27 × 50 euros

x = 13.5 euros

Answer: Trinomial

Step-by-step explanation: This expression has 3 terms (2a^2, -5a, and 7), so it is a trinomial. An easy way to remember this is that 'tri' = 3, 'bi' = 2, and 'mono' = 1. Hope this helped :)

Answer:

x = 74.7m

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Step-by-step explanation:

I=P*R*T/100

R= I*100/P*T

so rate= I*100/3000*0.5

= 30000/1500

= 300/15

=20%

pls gimme brainliest I need it

Answer:

R = 20%

Step-by-step explanation:

Given

I = PRT , substitute corresponding values

300 = 3000 R × 0.5

300 = 1500 R ( divide both sides by 1500 )

0.2 = R ( multiply value by 100% ) , that is

R = 0.2 × 100% = 20%

Answer:Jim gets £24

Step-by-step explanation:

Let the amount Natasha gets be represented as x

SO that Krutika getting  three times as much as Natasha be represented as 3x

AND Jim getting  twice as much as Krutika  be represented as 2 x 3x=6x

The equation to show how much each gets can be represented as

x + 3x  +6x=40

Solving

x +3x + 6x=40

10x =40

x =40/10 =4

Natasha gets £4

Krutika gets 3x =3x4= £12

Jim gets 6x=6 x4= £24

Answer:

y=4x + 10

Step-by-step explanation:

Parallel lines always have the same slope. The point that you have is the y-intercept because the x is 0. So now you have both the slope and y- intercept and just need to sub it into the y=mx+b equation

The equation of line passes through the point (0, 10) will be;

⇒ y = 4x + 10

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (0, 10).

And, The parallel line is,

⇒ y = 4x - 3

Now,

Since, The equation of line passes through the point (0, 10).

So, We need to find the slope of the line.

Since, The slope of the parallel line is same.

Hence, Slope of the line is,

y = 4x - 3

m = dy/dx = 4

m = 4

Thus, The equation of line with slope 4 is,

⇒ y - 10 = 4 (x - 0)

⇒ y - 10 = 4x

⇒ y = 4x + 10

Therefore, The equation of line passes through the point (0, 10) will be;

⇒ y = 4x + 10

Step-by-step explanation:

The range of a dataset is the difference between the maximum and minimum value :

The staring point of the whisker is the minimum = 4

The end point of he whisker is the maximum = 96

The range of the box and whisker plot is Hence,

Minimum = 4

Maximum = 98

Range = 98 - 4

First, you add all the marbles together to make the total. 6 + 5 + 4 + 9 = 24.

Then, make 6 the numerator and 24 the denominator. [tex]\frac{6}{24}[/tex]

Next, simplify. [tex]\frac{6}{24}[/tex] = [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]

Answer:

Let me give you an example of a segment addition problem that uses three points that asks the student to solve for x but has a solution x = 20.

First, I assumed values for each x, y and z and then manipulated their coefficients to get the total at the end of each equation.

20 + 10 +30 = 60

40 + 0 + 40 = 80

40 + 10 = 50

Then exchangeing these numbers into values and we have the following equation.

x + 2y + 3z = 60

2x + 4z = 80

2x + z = 50

If you will solve them manually by substituting their variables into these equations, you can get

x = 20

y = 5

z = 10

Answer: adults = $10

Step-by-step explanation:

x = adults

y = children

2x + 2y = 30

2x + 3y = 35

Using the elimination method:

2x + 2y = 30

-2x - 3y = -35 (multiplied by -1, to give 2x -2x = 0)

Solve for y...

2y = 30

-3y = -35

Add together...

-y = -5

Multiply by -1 to give positive value for y...

y = $5

Plug into one of the original equation to find x...

2x + 10 = 30

2x = 20

x = $10

Answer:

k = 27/4

y = 283.5

Step-by-step explanation:

Let

y = amount of water used

x = number of dogs washed

y = kx

y = 81 gallons

x = 12 dogs

y = kx

81 = k * 12

81 = 12k

Divide both sides by 12

81/12 = 12k/12

k = 81/12

k = 27/4

k = 6.75

Find x when y = 42 dogs

y = kx

y = 27/4 * 42

y = (27*42) / 4

y = 1,134 / 4

y = 283.5

y = amount of water used = 283.5 gallons

You would use this formula for the problem...

(C=2πr) The circumference equals 2 multiplied by pi and radius.

In this problem it says diameter, but the diameter is just twice the length of the radius, so just multiply the radius by 2. Plugin your number.

C=2π(2) since 2 is half of 4, that's your radius.

Your answer is roughly C= 12.57.

Answer:

Speed of plane is 250 miles per hour and speed of wind is 50 miles per hour

Step-by-step explanation:

Let x represent the speed of the wind. When travelling with the wind, the plane travels 1200 miles within 4 hours. Hence the speed of the plane with the wind is:

speed = distance / time = 1200 miles / 4 hours = 300 miles per hour

When travelling against the wind, the plane travels 1200 miles within 6 hours. Hence the speed of the plane against the wind is:

speed = distance / time = 1200 miles / 6 hours = 200 miles per hour

Therefore:

300 - x = 200 + x

300 - 200 = x + x

2x = 100

x = 50 miles per hour

The speed of the wind = 50 miles per hour. The speed of the plane = 300 - 50 = 200 + 50 = 250 miles per hour
