Me. Jackson has an empty pyramid and an empty prism. The base of the pyramid is congruent to the base of the prism, and their he

Answer:

Volume of water required to fill the pyramid is \frac{1}{3}rd of the water required to fill the prism completely.

Step-by-step explanation:

Let Mr Jackson has an empty rectangular pyramid and rectangular prism.

Height and base of both are congruent.

So volume of rectangular pyramid V_{1}=\frac{1}{3}(\text{Area of the base})(\text{Height})

V_{1}=\frac{1}{3}(A_{1})(h)

Volume of the rectangular prism = (Area of the base)(height)

V_{2}=(A_{2})(h)

\frac{V_{1}}{V_{2}}=\frac{\frac{1}{3}(A)h}{(A)h} [ Since A_{1}= A_{2} ]

\frac{V_{1}}{V_{2}}=\frac{1}{3}

V_{1}=\frac{1}{3}(V_{2})

Therefore, amount of water required to fill the pyramid is \frac{1}{3}rd of the water required to fill the prism completely.

Which congruence theorems can be used to prove ΔEFG ≅ ΔJHG? Select two options.
mezya [45]
<h2><u><em>Answer: </em></u></h2><h2><u><em> </em></u></h2>

ASA  and AAS

<h2><u><em>Step-by-step explanation: </em></u></h2>

We do not know if these are right triangles; therefore we cannot use HL to prove congruence.

We do not have 2 or 3 sides marked congruent; therefore we cannot use SSS or SAS to prove congruence.

We are given that EF is parallel to HJ.  This makes EJ a transversal.  This also means that ∠HJG and ∠GEF are alternate interior angles and are therefore congruent.  We also know that ∠EGF and ∠HGJ are vertical angles and are congruent.  This gives us two angles and a non-included side, which is the AAS congruence theorem.

Since EF and HJ are parallel and EJ is a transversal, ∠JHG and ∠EFG are alternate interior angles and are congruent.  Again we have that ∠EGF and ∠HGJ are vertical angles and are congruent; this gives us two angles and an included side, which is the ASA congruence theorem.

The tiles that Bruce used were each of a square foot in the area. The table shows the area covered by Felicia’s tiles in terms o
Allisa [31]

Answer:

Step-by-step explanation:

We have to write an equation which represents the area of Felicia covered y in terms of the number of tiles she used.

Let x= Number of tiles

y=Area  covered by  Felicia's tile

x_1=9, x_2=18, x_3=27

y_1=1, y_2=2,y_3=3

\frac{x_1}{y_1}=\frac{9}{1}=9

\frac{x_2}{y_2}=\frac{18}{2}=9

\frac{x_3}{y_3}=\frac{27}{3}=9

The ratio of x and y remains constant.Therefore, it is direct proportion .

Equation of direction proportion is given by

\frac{x}{y}=k

Where

k=The value of ratio of x and y

x and y are variables

We have k=9

Substitute the values in the equation

Then, we get

\frac{x}{y}=9

x=9y

y=\frac{1}{9}x

This is required equation which representing the area of Felicia covered y in terms of the number of tile she used x.

The table shows the concentration of a reactant in the reaction mixture over a period of time.
saveliy_v [14]
<h3>Option C</h3><h3>The average rate of the reaction over the entire course of the reaction is: 2.0 \times 10^{-3}</h3>

<em><u>Solution:</u></em>

Average rate is the ratio of concentration change to the time taken for the change

Average\ rate = \frac{ \triangle c }{\triangle t }

The concentration of the reactants changes 1.8 M to 0.6 M

here, the time interval given is 0 to 580 sec

Therefore,

Average\ rate = \frac{1.8-0.6}{580} \\\\Average\ rate = \frac{1.2}{580} \\\\Average\ rate \approx 2.0 \times 10^{-3}

Thus option C is correct
