Find the volume of the composite solid. Round your answer to the nearest tenth.​
amm1812

Answer:

Volume of the Figure =825.38m^3

Step-by-step explanation:

Volume of the figure = Volume of the Upper cone+Volume of the lower cone

Volume of a cone = \pi *r^2*\frac{h}{3}

Volume of the Upper Cone with  

height=12m

radius=6m

                       3.14*6*6*\frac{12}{3}

                        =3.14*6*6*4\\\\=3.14*36*4\\\\=3.14*144\\\\=147.14m^3

Volume of the Lower cone with radius=6m and height=18m

                            =3.14*6*6*\frac{18}{3} \\\\=3.14*6*6*6\\\\=3.14*36*6\\\\=3.14*216\\\\=678.24m^3

Volume of the Whole Figure =   147.14+678.24

Volume of the Figure  =825.38m^3

A function models the growth of a sample starting with 40 bacteria with the ability to double every two hours. Which graph
natima [27]

Answer:

The function is y = 40 * 2^(x/2)

The graph is in the image attached

Step-by-step explanation:

The function that models this growth is an exponencial function, that can be described with the following equation:

y = a * b^(x/n)

Where a is the inicial value, b is the rate of growth, x is the time and n is the relation between the time and the rate (the rate occurs for every two hours, so n = 2).

Then, using a = 40, r = 2 and n = 2, we have:

y = 40 * 2^(x/2)

If we plot this function, we have the graph shown in the image attached,

It is an exponencial graph, where the value of y increases very fast in relation to the increase of x.

Math! Who’s knows the answer?
kykrilka [37]

Answer:

M=30 degrees

because 102+148=150 and 180-150=30. (remember the sum of a triangle is 180 degrees)

the congruence statement would be SAS (side angle side) because 102 and 48 are the same in both triangles, but the third side is not the same.

The price of a refrigerator is Rs 66,400 after including GST at the rate of 17% . what is the amount of GST.
Elden [556K]
<h3>Answer:</h3>

The amount of GST is Rs 9,647.87

Step-by-step explanation:

<h2>Given :</h2>

• The price of a refrigerator = Rs 66,400

• Price including GST

• Rate of GST = 17 %

<h2>To Find :</h2>

• The amount of GGS

<h2>Solution :</h2>

★ GST Amount = Original cost of the product or service - (Original cost of the product or service) x (100 ) / (100 + GST%)

⇒ 66,400 − (66,400) × (100) / (100 + 17)

⇒ \mathsf{66,400 - ( 66,400 \times \dfrac{100}{(100 + 17)} )}

⇒ 9,647.87

GST Amount = Rs 9,647.87

∴ The amount of GST is Rs 9,647.87
