Answer:

volume ≈ 572.27 mm³

Step-by-step explanation:

The icicle is in the shape of an inverted cone with a diameter of 9 mm and a height of 27 mm. To find how much in cubic millimetres the frozen water is in the icicle can be calculated below.

In other words the question want us to find the volume of the cylinder. The volume of the cone can be represented as follows:

volume of a cylinder = 1/3πr²h

where

r = radius

h = height

diameter =  9 mm

height = 27 mm

r = diameter/2 =  9/2 = 4.5

volume = πr²h

volume = 1/3 × 3.14 × 4.5² × 27

volume = 1/3 × 3.14 × 20.25 × 27

volume = 1/3 × 63.585 × 27

volume = 1716.795/3

volume = 572.265 mm³

volume ≈ 572.27 mm³

x = 3

Step-by-step explanation:

4x + 3 + 7x = -2x + 42

11x + 3 = -2x + 42

13x = 39

x = 3

Answer:

x=3

Step-by-step explanation:

4x+3+7x=-2x+42

combine like terms

11x+3=-2x+42

add 2x to both sides

13x+3=42

subtract 3 from both sides

13x=39

divide both sides by 13

x=3

Answer:

Y-6=-1/2(x-(-1) )

Step-by-step explanation:

The Equation for the point-slope of the line is y - 6 = -1/2(x + 1).

A line's slope is defined as the ratio of the change in y coordinates to the change in x coordinates.

Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.

Given coordinates (-1,6) and (1,5).

the slope of line is given by,

m = (y₂- y₁)/(x₂ - x₁)

y₂- y₁ = 5 - 6 = -1

x₂ - x₁ = 1 - (-1) = 2

m = -1/2

to find the equation at y = 6

when y = 6, x = -1

the equation is given by

y - y₁ = m(x - x₁)

y - 6 = -1/2(x -(-1))

y - 6 = -1/2(x + 1)

Hence equation of a line is y - 6 = -1/2(x + 1).

Answer:

Step-by-step explanation:

Answer:

153.36g

Step-by-step explanation:

Density is defined as the ratio of mass per unit volume of a material.

Density = Mass/Volume

Given the edge of a cube which is equivalent to its length L to be 6cm.

Density of the cube = 0.71g/cm³

Volume of the cube = L³

Volume = 6³

Volume of the cube = 216cm³

Mass = Density × Volume

Mass of the cube = 0.71×216

Mass of the cube = 153.36grams

Answer:

153.36 grams

Step-by-step explanation:

Density is mass divided by volume: d = m/v.

Here, we already know that d = 0.71 g/cm³.

We can find the volume of hte cube. The volume of a cube is denoted by:

V = s³, where s is the side length

The cube's length is 6, so plug this in:

V = s³

V = 6³ = 216 cm³

Plug these values in:

d = m/v

0.71 g/cm³ = m / 216 cm³

m = 0.71 * 216 = 153.36 grams

The answer is 153.36 grams.

The number of tigers decays by a factor of

                                                                         [tex]\dfrac{4}{5}[/tex]    every    0.50 years  

Explanation:

The correctly written function is

         [tex]N(t)=650\cdot \bigg(\dfrac{16}{25}\bigg)^t[/tex]

Convert 16/25 into its equivalent form (4/5)²

          [tex]N(t)=650\cdot \bigg(\dfrac{4}{5}\bigg)^{2t}[/tex]

If you make t = 1/2, this is half-year, the population of tigers will decay by a factor of 4/5 in that time. Every time the half-year passes, the population is multiplied by 4/5, which means that the polulation will decay by a factor of 4/5 whenever half a year elapses.

Hence, the number of tigers decays by a factor of 4/5 every 0.50 years.

The tiger population model indicates a decay by a factor of 4/5 every year. This factor shows the yearly reduction rate for the tiger population in Siberia.

To determine the rate of change in the tiger population modeled by the function N(t) = [tex]650 \cdot \left(\frac{16}{25}\right)^t,[/tex] we look at the decay factor in the exponential function. The base of the exponent, [tex]\frac{16}{25}[/tex], indicates that the population is decaying.

This decay factor can be expressed as [tex]\frac{4}{5}[/tex], where every year, the number of tigers decays by a factor of  [tex]\frac{4}{5}[/tex]. Thus, we can complete the sentence as follows:

The number of tigers decays by a factor of  [tex]\frac{4}{5}[/tex] every year.

A point when rotated 180º about the origin flips the sign of the coordinates. Thus, point A' after rotating point A (-3,5) 180º about the origin would have coordinates (3,-5).

A rotation of 180º about the origin essentially changes the signs of the coordinates. If we have Point A as (-3, 5), after a 180° rotation about the origin, you'll get Point A', which will be the opposite of Point A. That means it turns (-3, 5) to (3, -5).

Rotation about the origin flips the point across both axes. This is based on a rule in mathematics: When we rotate a point 180° about the origin, (x, y) becomes (-x, -y).

The coordinates of A' after the 180° rotation are (3, -5).

The value x is 1, if the perimeter of square and rectangle are same. The perimeter of square and rectangle is 12 units.

Step-by-step explanation:

The given is,

                A square in a rectangle have the same perimeter

                The length of a side of the square is 4x-1

                The length of the rectangle is 2x+2 and width is 2x

Step:1

                Let, a - Side of square

                        l - Length of the rectangle

                       w - Width of the rectangle

Step:2

                Formula for perimeter of square is,

                                    [tex]p=4a[/tex].............................(1)

                Formula for perimeter of rectangle is,

                                   [tex]p=2(l+w)[/tex]....................(2)

Step:3

                From given,

                            Equation (1) = Equation (2)

                                 [tex]4a = 2 (l+w)[/tex]

               where,

                         a = 4x-1

                          l = 2x+2

                         w = 2x

               Substitute the values,

                       4 ( 4x-1 ) = 2 ( 2x+2+2x )

                            16x - 4 = 2 (4x + 2)

                            16x - 4 = 8x + 4

                          16x - 8x = 8                      

                                   8x = 8

                                     x = 1

Step:4

         Substitute the values of x,

                   a = 4(1)-1 = 3

                     l = 2(1)+2) = 4

                   w = 2(1) = 2

          Perimeter of square and rectangle is 12 units

Result:

           The value x is 1, if the perimeter of square and rectangle are same. The perimeter of square and rectangle is 12 units.
