Determine the volume of the rectangular prism.<br>​
Flauer [41]

Answer:

<h2><u>50 ft³</u></h2>

Step-by-step explanation:

We know the formula for a rectangular prism is length × width × height

We also know all the sides so we can rewrite the formula replacing variables.

The length is 8, the width is 2\frac{1}{2} and the height is 2\frac{1}{2}

8 × 2\frac{1}{2} × 2\frac{1}{2}

Multiply which ever way is easy for you. I am just multiplying from left to right.

8 × 2\frac{1}{2} = 20

20 × 2\frac{1}{2} = 50

Now we get 50. Before we put our answer as 50, there are two more steps.

First we need to add the measurement unit which is feet or ft

We also need to add ³ since it is volume

<u>50 ft³ is our final answer</u>

A family built a house in a beach resort area. In 1990, the house was 430 ft from the water. With erosion, the house was 400 ft
neonofarm [45]

We develop an equation for the given situation by first writing the general equation for lines,

                                y = mx + b

Substituting to this given the values given above,

(1990)                      430 = b

(2000)                      400 = m(10) + 430

The value of m from the equation in 2000 is -3. Thus, the equation of that relates the variables is,

                              y = -3x + 430

-5x-18y=-28 and -10x+9y=-11 solve elimination
Dmitry [639]

Answer:

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}

x=2,\:y=1

Step-by-step explanation:

Given the equations

-5x-18y=-28

-10x+9y=-11

solving the system of the equation by elimination method

\begin{bmatrix}-5x-18y=-28\\ -10x+9y=-11\end{bmatrix}

\mathrm{Multiply\:}-5x-18y=-28\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-10x-36y=-56

\begin{bmatrix}-10x-36y=-56\\ -10x+9y=-11\end{bmatrix}

-10x+9y=-11

-

\underline{-10x-36y=-56}

45y=45

\begin{bmatrix}-10x-36y=-56\\ 45y=45\end{bmatrix}

solve 45y=5 for y:

45y=45

\frac{45y}{45}=\frac{45}{45}

y=1

\mathrm{For\:}-10x-36y=-56\mathrm{\:plug\:in\:}y=1

solve -10x-36\cdot \:1=-56 for x:

-10x-36\cdot \:1=-56

-10x-36=-56

Add 36 to both sides

-10x-36+36=-56+36

-10x=-20

\frac{-10x}{-10}=\frac{-20}{-10}

x=2

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}
