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

Compute the range of the box and whisker plot. Type a numerical answer in the space provided. DO not type spaces in your answer.
Answer:
94
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
Range = 94

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

Write story problem that uses addition and has a solution of 6 (x=6)
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

£40 is divided between Jim, Krutika & Natasha so that Jim gets twice as much as Krutika, and Krutika gets three times as much as Natasha. How much does Jim get?
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

Gift Wrapping A gift box has the shape of a rectangular prism. How much wrapping paper do you need to cover the box?
Answer: v= 3360
If you’re looking for the volume V=whl =14 • 16 • 15= 3360
answer:
768 in²
step-by-step explanation:
since the box is being wrapped, you'll need to use the tsa (total surface area) formula-
a=2(w*l+h*l+h*w)
= 2·(6·15+14·15+14·6)

Y varies directly with x. If y = 15 when x = -18, find y when x = 1.6.
Someone please help me! I’ve been stuck on this forever!
Answer:
y = -4/3
Step-by-step explanation:
A direct variation equation has the form
y = kx
We need to find the value of k for this situation.
For that, we use the given values of x and y and solve for k.
When x = -18, y = 15.
15 = k × -18
k = 15/(-18)
k = -5/6
Now that we know the value of k for this specific situation, we write the equation of direct variation for our case.
y = -5/6 x
Finally, we find y when x = 1.6 using our equation.
y = -5/6 x
y = -5/6 × 1.6
y = -8/6
y = -4/3
Write the equation of a line parallel to the line y = 4x - 3 and passing through the point (0,10).
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
What is Equation of line?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

Answer:
189.27in^2
Step-by-step explanation:
Area of the rectangle is l*w
15*10= 150
Area of the circle is π r^2
We don't have radius but we have diameter so 10/2 =5
so A= π 5^2
78.53982, but we need half that since its only half a circle.
78.53982/2 = 39.26991
39.26991 + 150 = 189.26991

A plane travels 1200 miles from San Diego, Ca to Portland, Oregon. On the way there, the plane traveled with the wind and made it in 4 hours. On the return trip, the plane traveled against the wind and made it in 6 hours. Find the speed of the plane and the speed of the wind.
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

f. Do the segments connecting the coordinates (-1,6), (4,2), and (7,6) form a right triangle? Show
work that leads to your answer.
Answer:
No, these segments do not form a right triangle.
Step-by-step explanation:
We need to calculate the distances between the points, taking 2 at a time:
From (-1, 6) to (4, 2), x increases by 5 and y decreases by 4. The distance between the two points, by the Pythagorean Theorem, is d = √(5² + 4²), or √41.
From (-1, 6) to (7, 6) x increases by 8 but y stays the same: 6. The distance between these two points is therefore 8.
Finally, from (4, 2) to (7, 6), x increases by 3 and y by 4, and so d = 5.
So now we have the 3 side lengths: √41, 8 and 5.
Squaring them, we get 41, 64 and 25. These do not satisfy the Pythagorean Theorem: 41 + 25 is not equal to 64.
No, these segments do not form a right triangle.
