Answer: 96 cubic units

Step-by-step explanation: I checked on Khan and that’s what they’re saying is the correct answer.

Answer:

The volume of the cone is 96 cubic unit.

Step-by-step explanation:

volume of squared based pyramid = (1/3) × (Base Area) × (Height).

                      96 [tex]unit^{3}[/tex]                        = (1/3)× 30×(Height)

                                            9.6 unit    = Height

volume of cone  = (1/3) × (Base Area) × (Height).

                             = (1/3) × 30 ×      9.6 unit    

                             = 96[tex]unit^{3}[/tex]

Answer:

  $131,600

Step-by-step explanation:

If the listing price is P, then the net is the difference between that and all of the various costs.

  P -(5%×P) -94,000 -16000 = 15,000

  0.95P = 125,000

  P ≈ 131,600 . . . . . . divide by 0.95

The minimum listing price must be $131,600.

Answer:

0.1190

Step-by-step explanation:

If z = -1.18, the total area to the left under the standard normal curve is taken from the z-distribution table attached;

P(z < - 1.18) = 0.1190

Also, to the right of z = 1.18, we have;

P(z > 1.18) = 1 - P(z < 1.18)

From the second image attached from z-table, we have;

P(z > 1.18) = 1 - 0.8810

P(z > 1.18) = 0.1190

Thus, the total area to the left of z= - 1.18 and to the right of z= 1.18 under the standard normal curve is 0.1190

This one takes time to type all the math work.

Let me see.

There are two triangles here.

They both have the same area.

A = (1/2)(base)(height) times 2

A = (1/2)(42)(56) times 2

A = 1,176 times 2

A = 2,352 inches^2.

We also have three rectangles. We need to find the area of each rectangle individually.

Area of bottom rectangle = 42 times 72 or 3,024 inches^2.

Area of back rectangle = 56 times 72 or 4,032 inches^2.

Area of slanted rectangle = 70 times 72 0r 5,040 inches^2.

We now add all the areas together to find the total area of the entire figure.

Total Area = 2,352 inches^2 + 3,040 inches^2 + 4,032 inches^2 + 5,040 inches^2

Total area = 14,448 inches^2

Done!

Step-by-step explanation:

Answer:

46.44 cm 3

Step-by-step explanation:

Area of the composite figure, which is not drawn to scale is,

⇒ 488 cm²

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

To find the area of the composite figure, which is not drawn to scale.

Now, The figure is made by a rectangle and a triangle.

We know that;

Area of rectangle = Lenght x Width

Hence, We get;

Area of rectangle = Lenght x Width

Area of rectangle = 22 x 17

Area of rectangle = 374 cm²

And, Area of triangle = 1/2 × Height × Base

⇒ Area of triangle = 1/2 × (22 - 10) × 19

⇒ Area of triangle = 1/2 × 12 × 19

⇒ Area of triangle = 114 cm²

Thus, Area of the composite figure, which is not drawn to scale is,

⇒ 374 + 114 cm²

⇒ 488 cm²

Answer:

  5 1/2

Step-by-step explanation:

You can use the distributive property to eliminate parentheses, then add the terms that result.

  5(3/5 +1/2) = 5(3/5) +5(1/2) = 3 + 5/2 = 3 + 2 1/2 = 5 1/2

__

Or, you can add the numbers, then multiply by 5. This is the way the evaluation should be done according to the Order of Operations.

  5(3/5 +1/2) = 5(6/10 + 5/10) = 5(11/10) = 11/2 = 5 1/2

Answer:

5 1/2.

Step-by-step explanation:

5*(3/5+1/2)

= 5 * (6/10 + 5/10)

= 5 * 11/10

= 55/10

= 5 1/2.

Answer:

Step-by-step explanation:

x + 4(1/x) = 13/3

x + 4/x = 13/3

x^2 -13/3x + 4 = 0

3x^2 - 13x + 12 = 0

Δ = 169 - 144 = 25

x1 = (13 + 5)/6 = 3

x2 = (13-5)/6 = 4/3

Answer:

4/3 or 3

Answer:

The answer is A. 8, 9, 10

Answer:

A. 8, 9, 10.

Step-by-step explanation:

Consecutive numbers counting numbers which are 1 greater than the other, therefore:

x + (x + 1) + (x + 2) = 27

(x + x + x) + (1 + 2) = 27

3x + 3 = 27

–3 –3

3x = 24

÷3 ÷3

x = 8.

x = 8 → [ x + (x + 1) + (x + 2) ] =

(8) + (8 + 1) + (8 + 2) = 8 + 9 + 10

Answer:

  40 square units

Step-by-step explanation:

The area can be considered as that of two trapezoids, a rectangle, and a triangle. The total area is the sum of the areas of these.

Draw two horizontal lines, one beginning at the left-most point, and another 2 units below that. Draw a vertical line segment extending the vertical line at the top down to the first horizontal line. Now the figure is divided as described above.

The upper left trapezoid has bases of 3 and 5, and a height of 4. Its area is ...

  A = 1/2(b1 +b2)h

  A = (1/2)(3 +5)(4) = 16

The trapezoid between the two horizontal lines has bases of 8 and 7, and a height of 2. Its area is ...

  A = (1/2)(8 +7)(2) = 15

The rectangle at upper right has a base of 2 and a height of 3. Its area is ...

  A = bh

  A = 2(3) = 6

The triangle at the bottom has a base of 3 and a height of 2. Its area is ...

  A = 1/2bh

  A = 1/2(3)(2) = 3

Then the total area of all of these pieces is ...

  Area = 16 +15 +6 +3 = 40 . . . . square units

Answer:

Answer:

The sample size 'n' = 72,030

Step-by-step explanation:

Step(i):-

Given that the Estimate Error = 0.013

Given that the standard deviation of the Population = 1.5

The estimated error is determined by

[tex]E = \frac{Z_{0.98} S.D }{\sqrt{n} }[/tex]

Step(ii):-

Given that the Level of significance = 0.98 or 0.02

Z₀.₀₂ =   2.326

The estimated error is determined by

        [tex]E = \frac{Z_{0.98} S.D }{\sqrt{n} }[/tex]

   [tex]0.013 = \frac{2.326 X 1.5 }{\sqrt{n} }[/tex]

      [tex]\sqrt{n} = \frac{3.489}{0.013} = 268.38[/tex]

Squaring on both sides, we get

    n =  72,030

Final answer:-

The sample size 'n' = 72,030

Answer:

B

Step-by-step explanation:

So remember that a quarter of a circle is 90 degrees, a half of a circle is 180 degrees, and a whole circle is 360 degrees.

Looking at the image shown, it must be half a circle, whihc is 180 degrees. The image tells us that the 1st angle is 7 degrees. Now, we must find the 2nd angle.

Heres what we know however:

angle 1 + angle 2 = 180 degrees.

How do we know this?

Well, there are only 2 angles in this 180 degrees. We know that the first one is 7 degrees.

Lets input that into our nice lil equation to get an answer:

7 degrees+angle 2 = 180 degrees

Now lets solve.

Subtract 7 on both sides, and your left with:

angle 2 = 173 degrees.

So the answer must be:

173 degrees

Answer:

The population growth rate is of 1.86%.

Step-by-step explanation:

Population growth rate:

Immigration plus births subtracted by emigration and deaths.

In this question, we have that:

Birth: 14.3 per 1000

Death: 11.8 per 1000

Immigrations: 21.6 per 1000

Emigrations: 5.5 per 1000

Rate:

[tex]\frac{14.3 + 21.6 - 11.8 - 5.5}{1000} = \frac{18.6}{1000} = 0.0186[/tex]

As a percentage:

Multiply by 100%. So

0.0186*100% = 1.86%

The population growth rate is of 1.86%.
