Answer:

  400%

Step-by-step explanation:

Suppose sales in 1954 were 500. Then 80% of that amount is 400. A drop of 400 puts sales in 1955 at 500 -400 = 100.

The increase back to 500 in 1956 is an increase of 400 from a base of 100. As a percentage increase, that is ...

  400/100 × 100% = 400% . . . . increase from 1955 to 1956

Answer:

The length of side AB is [tex]\sqrt{50}[/tex] units.

The length of side BC is [tex]\sqrt{65}[/tex] units.

The length of side AC is [tex]\sqrt{145}[/tex] units.

Step-by-step explanation:

To find the length of each side, we use the formula for the distance between two points.

Distance between two points:

Points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Side AB:

Points [tex]A(-3,6),B(2,1)[/tex]. So the distance between them is:

[tex]D = \sqrt{(2-(-3))^2 + (1-6)^2} = \sqrt{50}[/tex]

The length of side AB is [tex]\sqrt{50}[/tex] units.

Side BC:

Points [tex]C(9,5),B(2,1)[/tex]. So the distance between them is:

[tex]D = \sqrt{(2-9)^2 + (1-5)^2} = \sqrt{65}[/tex]

The length of side BC is [tex]\sqrt{65}[/tex] units.

Side AC:

Points [tex]A(-3,6),C(9,5)[/tex]. So the distance between them is:

[tex]D = \sqrt{(9-(-3))^2 + (5-6)^2} = \sqrt{145}[/tex]

The length of side AC is [tex]\sqrt{145}[/tex] units.

Answer:

415/619

Step-by-step explanation:

619 is a prime number, so the fraction is in simplest form already.

Answer:im not forsure

Step-by-step explanation:

The number is -34

A number is an arithmetic value used for representing the quantity and used in making calculations.

Given that, seven less than half the number is equal to -24.

Let the number be x,

Therefore,

(x/2) - 7 = -24

(x/2) = -17

x = -34

Hence, the number is -34

Step-by-step explanation:

Answer:

x = -1/5, x = i sqrt(30)/5,  x = -i sqrt(30)/5

Step-by-step explanation:

25x^3 + 5x^2 + 30x + 6 = 0

5x^2(5x + 1) + 6(5x + 1) = 0

(5x + 1)(5x^2 + 6) = 0

5x + 1 = 0

5x = -1

x = -1/5

5x^2 + 6 = 0

5x^2 = -6

x^2 = -6/5

x = +/- sqrt(-6/5)

x = +/- i * sqrt(30)/5

x = i sqrt(30)/5 or x = -i sqrt(30)/5

Answer:

22.5 inches

Step-by-step explanation:

To find the unit rate, you divide the amount the plant grew by the amount of weeks. We learned that the plant grew 75 inches in 100 weeks, so we divide 75/100, to get 0.75. This means that the plant grows 0.75 inches per week, so in 30 weeks, it would grow 22.5 inches. This is calculated by multiplying 0.75 by 30 weeks.

Answer:

Hotdogs is 10

and Tacos  8 in numbers purchased

Step-by-step explanation:

Step one:

given data

Le  x represents the number of hotdogs purchased

and y represents the number of tac

hotdogs = $4 each

and tacos = $2.50 each

The total amount at hand = $60

Step two:

The systems of the equations for the situation is given as

4x+2.5y= 60---------1

x+y=18-----------------2

Required

The number of Hotdogs and Tacos purchased

from 2

x= 18-y

put x= 18-y in eqn  1

4(18-y)+2.5y= 60

72-4y +2.5y=60

collect like terms

-4y+2.5y=60-72

-1.5y= -12

divide both sides by -1.5

y= -12/-1.5

y= 8

put y= 8 in eqn 2

x+8=18

x= 18-8

x= 10

Answer:

Increasing → (-∞, -0.5)

Decreasing → (-0.5, ∞)

Step-by-step explanation:

From the picture attached,

Vertex of the parabola represents the highest point of the curve of a quadratic function 'f'.

Left part from the vertex is increasing and the right side is increasing.

x-coordinates of the vertex,

x = -0.5

Therefore, graph of the function is increasing in the interval (-∞, -0.5)

And decreasing in the interval (-0.5, ∞).

Answer:

The remaining tea = 0.305 kg

Step-by-step explanation:

The mass of Tea pack = 0.345 kg

The mass of tea taken = 40 g

as

Therefore, all we need is to subtract 0.04 kg from 0.345 kg to determine the tea left:

i.e.

Remaining Tea left = Total tea - Tea taken

                                = 0.345 - 0.04

                                = 0.305 kg

Therefore, the remaining tea = 0.305 kg

Answer: 12 = x + 4

Step-by-step explanation:

We know that the length of the green line is 12.

And the length of the black line will be equal to the sum of the lengths of the two smaller segments, x, and 4

Then the length of the black line is x + 4

We want to write an equation that says that the length of the green line is equal to the length of the black line, this is:

Length of green line = Length of black line

12 = x + 4

That is the equation we wanted.

Now we could solve it if we subtract 4 in both sides of the equation:

12 - 4 = (x + 4) - 4

8 = x

Answer:

x=0.25 or -1/4

Step-by-step explanation:

120x + 21 = -9

120x = -30 (-21 from both sides of equation)

x = -0.25 or -1/4 (divide 120 from both sides of equation)

Answer:x=1/4

Step-by-step explanation:

120x + 21  = -9

120x = -9 -21

120=-30

x=-1/4

2. The dictionary definition of a trapezoid (US; trapezium, UK) is ...

  a quadrilateral with one pair of parallel sides.

As a consequence of this condition, it is not possible for a trapezoid to be a parallelogram.

3. A rhombus is a special case of parallelogram in which all sides are the same length. A square is a special case of rhombus in which all angles are congruent (as are the diagonals). Yes, a rhombus may be a square.

[tex]\displaystyle 2b.[/tex] A rhombus can never be a square because although opposite interiour angles and all four sides are congruent, their interiour angles are not right angles.

[tex]\displaystyle 2a.[/tex] A trapezium is impossibly a parallelogram because a parallelogram has two pairs of parallel sides.
