Complete question

This composite figure is made of two identical pyramids attached at their bases. Each pyramid has a height of 2 units.

2 identical pyramids with rectangular bases are connected at their base. The height of the pyramid is 2. The lengths of the sides of the rectangle are 5 and 0.25 units.

Which expression represents the volume, in cubic units, of the composite figure?

Answer:

2(1/3(5)(0.25)(2))

Step-by-step explanation:

The volume of a rectangular pyramid is given as

1/3 × (Area of the base rectangle ) × Height

Area of the base rectangle = Length × Width

We are told in the question that:

The lengths of the sides of the rectangle are 5 and 0.25 units.

Area of the base rectangle = 5 units × 0.25 units

The height of the pyramid = 2 units

Therefore, the volume of the rectangular pyramid = 1/3× (5×0.25) × 2

We are also told in the question that this composite figure is made of two identical pyramids attached at their bases.

Therefore, expression that represents the volume, in cubic units, of the composite figure is given as:

2(1/3× (5×0.25) × 2) = 2(1/3(5)(0.25)(2))

Answer:

Step-by-step explanation:

Ray HK is an angle bisector, which means that it cuts the angle exactly in half.  So half of GHI is 60.  If GHK is 3x + 48, and that is half of angle GHI. then

3x + 48 = 60 and

3x = 12 so

x = 4

Answer:

The radius of the water bottle is 2.25 cm

Step-by-step explanation:

The water bottle is said to be cylindrical, so its volume can be expressed as the volume of a cylinder.

Volume of a cylinder V = πr^2 h

Where;

h = height

r = radius

Making the radius the subject of formula;

r^2 = V/πh

r = √(V/πh)

Given:

Volume V = 121 cm^3

height h = 7.6 cm

π = 3.14

Substituting the given values;

r = √(121/(3.14×7.6))

r = 2.25 cm

The radius of the water bottle is 2.25 cm

Answer:

The values are k = -2 and c = 1

Step-by-step explanation:

Since it's a division of polynomials we can calculate "c" and "k" by using the inverse operation, which is the product. We need to multiply "x + k" with "3x + 1" and sum it with 3, that should be equal to "3x² - 5x + c". We have:

[tex]3x^2 - 5x + c = (x + k)*(3x + 1) + 3\\3x^2 - 5x + c = 3x^2 + x + 3kx + k + 3\\3x^2 - 5x + c = 3x^2 + (1 + 3k)x + (k+3)[/tex]

In order for two polynomials to be equal, every coefficient must be equal, therefore:

[tex]-5 = 1 + 3k\\1 + 3k = -5\\3k = -5 -1\\3k = -6\\k = -2[/tex]

[tex]c = k + 3\\c = -2 + 3\\c = 1[/tex]

Answer:

2880 m

Step-by-step explanation:

find the area under the graph. i have split it into 3 areas A, B and C

A (trapezium) = 1/2 x (150 + 160) x 15 = 2325

B (trapezium) = 1/2 x (15 + 6 ) x (160 - 110) = 525

C (triangle) = 1/2 x 10 x 6 = 30

total = 2325 + 525 + 30 = 2880

Answer:

For a general quadrilateral; in addition s=½(a+b+c+d). Right: a parallelogram. Often, however, it is easiest to compute the area by dividing the quadrilateral into triangles. One can also divide into triangles to compute one side given the other sides and angles, etc.

Step-by-step explanation:

Answer:

As shown in picture:

A(-4, 1)

Z(-2, 3)

P(3, -4)

The length of AZ is calculated by:  

L = sqrt((-4 - -2)^2 + (1 - 3)^2) = 2.83

The length of AP is calculated by:

L = sqrt((3 - -4)^2 + (-4 - 1)^2) = 8.60

THe length of ZP is calculated by:

L = sqrt((3 - -2)^2 + (-4 - 3)^2) = 8.60

=>Perimeter of triangle AZP is calculated by:

P = AZ + AP + ZP = 2.83 + 8.60 + 8.60 = 20.3

Answer:

Sharing cone holds 9 times more popcorn than a skinny cone.

Step-by-step explanation:

Height of each cone = 9 inches

Radius of the sharing size cone = 3 times radius of the skinny size cone

Let the radius of skinny size cone = r

Then radius of the sharing size cone = 3r

Volume of the sharing size cone = [tex]\frac{1}{3}(\pi )(\text{Radius})^{2}(\text{Height})[/tex]

                                                     = [tex]\frac{1}{3}(\pi )(3r)^{2}(9)[/tex]

                                                     = 27πr²

Volume of the skinny size cone = [tex]\frac{1}{3}(\pi )(\text{Radius})^{2}(\text{Height})[/tex]

                                                       = [tex]\frac{1}{3}(\pi )(r)^{2}(9)[/tex]

                                                       = 3πr²

Ratio of the volumes = [tex]\frac{\text{Volume of sharing size cone}}{\text{Volume of skinny size cone}}[/tex]

                                   = [tex]\frac{27\pi r^{2}}{3\pi r^{2} }[/tex]

                                   = 9

Therefore, sharing cone holds 9 times more popcorn than a skinny cone.

Answer:

x=1, y=2

Step-by-step explanation:

2x+y =4

y = 2x

Substitute the second equation into the first

2x+ (2x) = 4

Combine like terms

4x = 4

4x/4 = 4/4

x = 1

Now find y

y = 2x

y = 2(1)

y = 2

Answer:

y = -x-2

Step-by-step explanation:

We are given a slope of -1 and the y intercept of -2

The slope intercept form of the equation for a line is

y = mx+b

where m is the slope and b is the y intercept

y = -1x +-2

y = -x-2

Answer:

y=-x -2

Step-by-step explanation:

Slope-intercept form is

y=mx+b

where m is the slope and b is the y-intercept

We know that the slope is -1. We also know that the y-intercept is (0, -2). For this form, we can disregard the 0, and say the y intercept is just -2.

So, m is -1, and b is -2. Substitute the values into the equation.

y=mx+b

y=-1x+-2

Simplify

y= -x -2

This is the equation of the line in slope-intercept form.

Answer: x=12.49

10^2 + x^2= 16^2

100 + x^2= 256

x^2=156

x=12.49

Step-by-step explanation:

Step 1:  Use Pythagorean Theorem

[tex]a^2 + b^2 = c^2[/tex]

[tex]10^2 + b^2 = 16^2[/tex]

[tex]100 + b^2 = 256[/tex]

[tex]100-100 + b^2 = 256-100[/tex]

[tex]b^2 = 156[/tex]

[tex]\sqrt{b^2}=\sqrt{156}[/tex]

[tex]b = 12.48999599679679641169378624188[/tex]

[tex]b = 12.49[/tex]

Answer: [tex]12.49[/tex]

Answer:

  18.8 m²

Step-by-step explanation:

The area of a sector is given by the formula ...

  A = (1/2)r²θ . . . . . . . r is radius, θ is the central angle in radians

To convert an angle in degrees to one in radians, multiply by π/180°.

Your 135° sector has an area of ...

  A = (1/2)(4 m)²(135°)(π/180°) = 6π m²

  A ≈ 18.8 m²

Answer:

Probably Dog.

Step-by-step explanation:

Since there is more dogs than anything else, it would probably be a dog.

Answer:

Total pets  available

20 pets

Cat  0.2 --> 20%

Dog  0. 35  --> 35%

Snake   0.05 --> 5%

Rabbit  0.15 --> 15%

Bird 0.25--> 25%

Step-by-step explanation:

Total pets are:

cats + dogs + snakes + rabbits + birds

4 + 7 + 1 + 3 + 5 = 20 pets available for adoption

To find probability dived the number available of each  pet by the total number of pets available.

Cat

4/20 = 0.2 --> 20%

Dog

7/20 = 0. 35  --> 35%

Snake

1/20 =  0.05 --> 5%

Rabbit

3/5 = 0.15 --> 15%

Bird

5/20 =0.25--> 25%

Answer:

The correct answer is option

[tex]d.\ x=-i, i, 3 \sqrt{5}\ or\ -3 \sqrt{5}[/tex]

Step-by-step explanation:

The given equation has a degree 4  (Highest power of [tex]x[/tex]):

[tex]x^4-44x^2-45=0[/tex] is the given equation which can be written as:

[tex](x^2)^2-44x^2-45=0 ...... (1)[/tex]

Let [tex]t=x^{2}[/tex] and putting it in equation (1):

[tex]t^2-44t-45=0 \\[/tex]

Solving the above quadratic equation in variable [tex]t[/tex]:

[tex]\Rightarrow t^2-45t+t-45=0 \\\Rightarrow t(t-45)+1(t-45)=0\\\Rightarrow (t+1)(t-45)=0\\\Rightarrow t =-1\ or\ 45[/tex]

We know that [tex]t=x^{2}[/tex]

So, [tex]x^{2} =-1\ or\ x^{2}= 45[/tex]

1. Solving [tex]x^{2} =-1[/tex]

[tex]\Rightarrow x = +\sqrt{-1}\ or\ -\sqrt{-1}\\\Rightarrow x = i\ or\ -i[/tex]

2. Solving [tex]x^{2} =45[/tex]

[tex]\Rightarrow x = +\sqrt{45}\ or\ -\sqrt{45}\\\Rightarrow x = 3\sqrt{5}\ or\ -3\sqrt{5}[/tex]

Hence, correct answer is:

[tex]x=-i, i, 3 \sqrt{5}\ or\ -3 \sqrt{5}[/tex]
