<h3>❍ Question -:</h3>

A cone has a base that is 21.9 feet squared and a height that is 6.1 feet. Find its volume in cubic feet.

<h3>❍ Explanation -:</h3>

In this question we are provided with the base of the cone that is 21.9 feet and height of the cone is 6.1 feet. We are asked to calculate the volume of the cone.

We know,

\star \: \small \underline{\boxed{ \rm{ Volume_{(cone)} = \dfrac{1}{3} × b × h}}}

Where,

  • b stand for base
  • h stand for height

Substituting the values we get

\small\sf{ Volume_{(cone)} = \dfrac{1}{3} × 21.9 × 6.1}

\rightarrow \small\sf{ Volume_{(cone)} = \dfrac{1}{ \cancel{3}} ×  \cancel{ 21.9} \:  7.3 × 6.1}

\rightarrow \small\sf{ Volume_{(cone)} =  7.3 × 6.1 = 44.53}

Volume of the cone = 44.53 feet³.

Answer:

  44.5 ft³

Step-by-step explanation:

The formula for the volume of a cone is ...

  V = 1/3Bh

where B is the base area and h is the height.

__

Using the given dimensions, we find the volume to be ...

  V = 1/3(21.9 ft²)(6.1 ft) = 44.53 ft³

The volume of the cone is about 44.5 cubic feet.

To answer this question, we have the start-up costs of $ 52,000

A monthly inflation of $ 0 is assumed

Operating costs  are $680

The daily gain  is $960

For the Part A.

The inequality that this situation represents

 960d-680d>52000

So:

d(960-680)>52000

Where d represents the number of days.

For the Part B.

To start earning, you must replace all the initial investment and cover the expenses per day. The time that must pass for this to happen is obtained by clearing "d" from the inequality.


 d>\frac{52000}{960-680}

d> 185.71 days

Then, the sum of the net profits will be greater than the initial investment after 186 days of starting the business.

Mohammad would like to graph the line that represents the total number of baseball cards he will
Marina CMI [18]

Answer:

To best show this information, the scale for the T-axis of his graph should go from 0 to at least 60.

To best show this information, the scale for the m-axis of his graph should go from 0 to at least 12.

Step-by-step explanation:

Mohammad will have collected T cards after m months, given that he buys 5 cards each month and he started with no cards.

The relationship describing this situation is

T=5m

When m=6, then T=5\cdot 6=30 cards.

When m=12, then T=5\cdot 12=60 cards.

To best show this information, the scale for the T-axis of his graph should go from 0 to at least 60.

To best show this information, the scale for the m-axis of his graph should go from 0 to at least 12.

Find the area of a trapezoid with base 1 side = 10 base 2 side = 16 and 3​
mart [117]

Answer:

Area of Trapezoid is 39 unit²

Step-by-step explanation:

Given as :

For A Trapezoid

The measure of base side 1 = b_1 = 10 unit

The measure of base side 2 = b_2 = 16 unit

The height of the Trapezoid = h = 3 unit

Let  The Area of Trapezoid = A square unit

<u>Now, From Formula</u>

Area of Trapezoid = \dfrac{1}{2} × (sum of opposite base) × height

I.e A =  \dfrac{1}{2} × (b_1 + b_2) × h

Or, A =  \dfrac{1}{2} × (10 unit + 16 unit) × 3 unit

Or, A =  \dfrac{1}{2} × (26 unit) × 3 unit

Or, A =  \dfrac{1}{2} × 78 unit²

Or, A = \dfrac{78}{2} unit²

I.e A = 39 unit²

So, The Area of Trapezoid = A = 39 unit²

Hence, The Area of Trapezoid is 39 unit² . Answer
