Given that Volume of triangular prism = 216 cubic centimetre

Given that Height of the pencil = 12 centimetre

Now we have to find the area of the base of the prism means find the area of triangular part.

Volume of triangular prism is given by formula:

Volume of triangular prism = (Area of base) x (Height of the prism)

now plug the given values

216= (Area of the base) x 12

Area of the base

18= Area of the base

Hence final answer is 18 square centimetres.

Joseph is building a cone using modeling clay. The cone has a radius of 6 cm and a height of 12 cm. Joseph adds additional clay,

dmitriy555 [2]

Cone Volume = (π • r² • h) ÷ 3

Original cone = (3.14 * 6^2 * 12) / 3

Original cone = 452.16 cc

Larger cone = (3.14 * 6^2 * 18) / 3 = 678.24 cc

Difference = (678.24 -452.16) = 226.08 cc

Answer:

"34,814" is the correct solution.

Step-by-step explanation:

The given values are:

Intercept coefficient,

$\beta_0 = 23,859$

Production coefficient,

$\beta_1 = 3.13$

Units sold,

x = 3,500

Now,

The total cost will be:

⇒ $\bar{y}=\beta_0+\beta_1 x$

On substituting the estimated values, we get

⇒ $=23,859+3.13\times 3,500$

⇒ $=23,859+10,955$

⇒ $=34,814$

While testing a new vaccine, a lab technician noticed that the number of bacteria reduced by half every minute. How long does it

son4ous [18]

To start, find your equation, n=3000(.5)^t, n being your number of bacteria and t being your time. Now plug in 375 for n and solve for t, 375=3000(.5)^t, .125=.5^t, $t=log_{.5} .125=3$ . This means your answer is 3 minutes. To check it, plug it into your equation. n=3000(.5)^t=3000(.125)=375
