Above are two different models of the same trapezoid-shaped pool. If the area of the model on the left is 2.5 sq cm, what is the area of the model on the right?

A.

40 sq cm

B.

10 sq cm

C.

20 sq cm

D.

18.5 sq cm

Answer:

Step-by-step explanation:

Length of the object = 4 ft

Breadth of the object = 4 ft

Height of the object = 3 ft

Volume / Area of the object = Length * Breadth * Height

                                                = 4 * 4 * 3

                                                = 48 ft³

Length of the cubical hole = 2 ft

Breadth of the cubical hole = 2 ft

Height of the cubical hole = 3 ft

Volume / Area of the cubical hole = Length * Breadth * Height

                                                          = 2 * 2 * 3

                                                          = 12 ft³

Remaining Area of the object = Area of the object - Area of the cubical hole

                                                    = 48 - 12 ft

                                                    = 36 ft

We can’t tell any area of a 3d object without it’s SA formulas.

Answer:

113.04

Step-by-step explanation:

To find the volume of a cone use the formula [tex]1/3 \pi r^2h[/tex].

The formula would be [tex]1/3*3.14* 3^2*12[/tex]

So the answer would be 113.04

Answer:

Step-by-step explanation:

Height = 12ft

Volume of cone = πr^2h/3

                            =3.14*3^2*12/3

                            = 3.14*9*4

                            = 113.04ft^3

Area of the base is 9 square feet, the lateral face area is 27 square feet, Lateral surface area is 27 square feet and total surface area  is 36 square feet.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The square has a side length of 3 ft

Area of the base is 3×3

Area of the base is 9 square feet

Now let us find the lateral face area = 2a√[(a²/4) + h²]

=2(3)√[(9/4) + 17.64]

=6√20

=27 square feet

Lateral surface area = a√(a²+4h²)

a=3, h=4.2

Lateral surface area = 3√(9+4(4.2)²)

= 3√(9+4(17.64))

3√(9+70.56

= 3√79.56

=3×9

=27 square feet

To find total surface area, we have to find the slant height by pythagoras theorem

(1.5)²+(4.2)²=l²

2.25+17.64=l²

20=l²

4.47=l

Now total surface area = a² + 2al

=3²+2(3)(4.47)

=9+26.82

=36 square feet

Hence, Area of the base is 9 square feet, the lateral face area is 27 square feet, Lateral surface area is 27 square feet and total surface area  is 36 square feet.

20%

Step-by-step explanation:

There are 30 total survey responses and 6 people chose bird and so 6 is 20% of 30 which means the answer is 20%.

Answer:

20%

Step-by-step explanation:

This is beacuse if we count all the types of animals the students choosed, it's 30. And 6 students selected bird. So, 30/6=5 and 5 is 20% of 30

THUS, ANSWER IS 20%

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

There are two ways a fair coin can land: heads and tails. Since there is an equal chance that the coin lands on heads and tails, there is half chance ([tex]\frac{1}{2}[/tex] or 50%) that the coin lands heads-up.

∴ Therefore, the probability as a fraction is [tex]\frac{1}{2}[/tex].

Tessellation

Step-by-step explanation:

The figure shown is a picture of a Tessellation

Where a Tessellation is a tiling of regular polygons (in two dimensions), polyhedra (three dimensions), or polytopes ( dimensions)

Answer:

Step-by-step explanation: yup it is right

20% of the students surveyed selected "Bird" as their favorite type of animal. Hence option D is correct.

To calculate the percentage of students who selected "Bird" as their favorite type of animal, we need to first determine the total number of students surveyed. From the bar graph, we can see that the total number of students is:

2 + 4 + 6 + 10 + 8 = 30

The number of students who selected "Bird" as their favorite type of animal is 6. To calculate the percentage, we can use the following formula:

Percentage = (Number of students who selected "Bird" / Total number of students surveyed) x 100%

Substituting the values we have:

Percentage = (6 / 30) x 100%

Percentage = 20%

Therefore, 20% of the students surveyed selected "Bird" as their favorite type of animal.

Step-by-step explanation:

I know this answer is right because the numbers got larger as the letters went to the right which means increase and the answers and graph makes logical sense to me. Hopefully you get a good grade on this.

Answer:

The correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

step by step:

From the number line we can observed that:

1) A, B, C and D lies between -1 and 0.

2) Point A and B lies between -1 and -0.5

3) Point C and D lies between -0.5 and 0

Therefore, the value of A and B must have a negative value lying between -1 and -0.5

Also, the value of C and D must have a negative value lying between -0.5 and 0.

Now consider the provided options.

Option A) A=-5/16,B=-9/16,C=-0.7,D=-0.4

This is Incorrect representation because the value of C and D should lying between -0.5 and 0.

Option B) A=-0.4,B=-0.7,C=-5/16,D=9/16

This is Incorrect representation because the value of A and B should lying between -1 and -0.5.

Option C) A=9/16,B=-5/16,C=-0.4,D=-0.7

This is Incorrect representation because the value of C and D should lying between -0.5 and 0.

Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

Here the value of A and B lying between -1 and -0.5 also the value of C and D lying between -0.5 and 0.

Also they are in ascending order from -1 to 0.

Hence, the correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

The height of the dead tree is 16 feet

The direction in which the tree should fall is Northeast, Northwest, Southeast, Southwest.

From the given question, since the ray is straight, AC is parallel to DF

Meanwhile triangles ABC and DEF are right angles,

AB/DE =BC/EF

AB/6 = 8/3

AB= 16 feet.

Thus, the height of the tree is 16 feet.

Since 16 ft> 15ft> 14ft> 13ft> 12ft

Therefore, the direction which the tree is falling is Northeast, Northwest, Southeast, Southwest.
