A gardener uses a tray of 6 conical pots to plant seeds. Each conical pot has a radius of 3 centimeters and a depth of 8 centimeters. About how many cubic centimeters of soil are needed to plant the full tray? Round to the nearest cubic centimeter.

Answers

Answer 1

By definition, the volume of a cone is given by:

[tex] V = (\frac{1}{3}) * (\pi) * (r ^ 2) * (h)
[/tex]

Where,

r: radius of the circular base

h: height of the cone

Since we have 6 conical pots, then the total volume is:

[tex]Vt=6V[/tex]

[tex] Vt = 6 * (\frac{1}{3}) * (\pi) * (r ^ 2) * (h)
[/tex]

Substituting values we have:

[tex] Vt = 6 * (\frac{1}{3}) * (3.14) * (3 ^ 2) * (8)

Vt = 452.16 cm ^ 3
[/tex]

Rounding to the nearest cubic centimeter:

[tex] Vt = 452 cm ^ 3
[/tex]

Answer:

are needed 452 cm^3 of soil to plant the full tray

Answer 2

The cubic centimeters of soil are needed to plant the full tray is approximately 452cubic in

Volume of a cone

The formula for calculating the volume of a cone is expressed as:

V = 1/3πr²h

r is the radius  = 3cm

h is the height = 8cm

Substitute

V =  1/3 * 3.14 * 3^2 * 8
V = 75.36 cubic cm

Since the gardener uses a tray of 6 conical pots to plant seeds, the total volume will be expressed as:

T = 6(75.36)
T = 452cubic in

Hence the cubic centimeters of soil are needed to plant the full tray is approximately 452cubic in

2 (3x-7)=-4x-6+9x-8

Answers

2 (3x - 7) = -4x - 6 + 9x - 8   Simplify 2 (3x - 7)
    6x - 14 = -4x - 6 +9x - 8    Combine like terms (-4x and 9x) (-6 and -8)
    6x - 14 = 5x - 14                 Subtract 5x from both sides
      x - 14 = -14                       Add 14 to both sides
            x = 0

Check your answer.

  2 (3x - 7) = -4x - 6 + 9x - 8        Substitute x for 0
2 (3(0) - 7) = -4(0) - 6 + 9(0) - 8   Multiply 3(0)
    2 (0 - 7) = -4(0) - 6 + 9(0) - 8   Multiply -4(0)

B (x) = 45.25- 0.25x

What is the remaining balance on the card if Dan bought 50 prints?

Answers

b(50)=45.25-0.25(50)
b(50)=45.25-12.5
b(50)=32.75
Final answer: $32.75
Final answer:

The remaining balance on the card after buying 50 prints is $32.75.

Explanation:

To find the remaining balance, B(x), on the gift card after buying x prints, we can substitute the value of x into the given function B(x) = 45.25 - 0.25x. In this case, x = 50.

Substituting x = 50 into the function, we have B(50) = 45.25 - 0.25(50) = 45.25 - 12.50 = 32.75.

Therefore, the remaining balance on the card after buying 50 prints is $32.75.

The floor of a rectangular room will be tiled with square tiles that measure 3 inches on each side. The room is 109 inches long and 103 inches wide. How many tiles, including parts of tiles, are needed to complete the job?

Answers

109 *103 = 11227 square inches

tile = 3^2 = 9 square inches

11227/9 = 1247.44 tiles are needed.

 you can't buy a partial tile so you would need 1248 tiles

Answer:

We need 1248 tiles to complete the job.

Step-by-step explanation:

First we have to get the area of the  room and the area of each tile

Area = long x wide

Room Area = 109 x 103 = 11227 square inches

Tile area = 3 x 3 = 9 square inches

To get how many tiles we need, we must divide the room area by the tile area

Q=11227/9= 1247,44 ≅1248

A large ice floe is floating at a speed of 3 kilometers per hour. A polar bear leaves the floe and swims in the opposite direction at 9 kilometers per hour. How long will it be before the polar bear is 4 kilometers away from the floe?

How do I do this??? My teacher never teaches me!!

Answers

Final answer:

The polar bear and the ice floe have a relative speed of 12 kilometers per hour. Given they're moving in opposite directions and the polar bear should end up 4 kilometers away, it would take approximately 0.33 hours or 20 minutes for the bear to reach this distance.

Explanation:

The subject of this problem is relative speed. When two objects are moving in the opposite direction, their relative speed is the sum of their individual speeds. In this case, the ice floe is moving at 3 kilometers per hour and the polar bear is swimming at 9 kilometers per hour. So, their relative speed is 3 + 9 = 12 kilometers per hour.

The distance between the polar bear and the floe is 4 kilometers. To find out how long it will be before the polar bear is 4 kilometers away from the floe, you would divide the total distance by the relative speed. Therefore, the time would be 4 kilometers divided by 12 kilometers per hour equals 0.33 hours, or approximately 20 minutes.

Step-by-step explanation:

Given in the picture is a right angled triangle

The coordinates of A are (-9,10) and B are (7,-2) and C is (4,-6)

Given that BC = 5 units

AB = distance between A and B

=distance between two points (-9,10) and (7,-2)

=[tex]\sqrt{(-9-7)^2+(10+2)^2} =\sqrt{256+144} \\=20[/tex]

Thus if we consider BC as base then AB is the height

Area of triangle = 1/2 bh = 1/2 (5)(20)

= 50 square units

The area of the triangle is: 50 square units.

What is the Area of a Triangle?

Area of a triangle = 1/2(base × height).

What is a division?

A division is a process of splitting a specific amount into equal parts. The number to be divided by another number is called the dividend. The number by which we divide another number (dividend) into equal parts is called the divisor.

For the given situation,

Kenji wants to divide 48.6 by 0.15.

Which line represents the line of reflection in this diagram?


f
g
h
i

Answers

The answer would be H, Because it is in the very center of both shapes which creates a line of symmetry which is used for the line of reflection


Hope this helped...

Answer:  The correct option is (C) h.

Step-by-step explanation:  We are given to select the correct line that represents the line of reflection in the given diagram.

We know that

A line of reflection is a line such that each point of the original figure and the image are equidistant from it.

In other words, we can say that the line of reflection is equidistant from the original figure and the image.

Now, from the figure, we can see that the line g is close on the figure on the left than that in the right. So, line g cannot be the line of reflection.

Line i is close the right figure on the upper half and it is close to the left figure on the lower half. So, line i also cannot be the line of reflection.

Line f cannot be the line of reflection because the shape of the figure is not same in both the sides of f.

The only line that is equidistant from both the figures is line h.

Thus, the line of reflection is line h.

Option (C) is CORRECT.
