A scale of a room is 3.5 in. long and 2 in. wide. Scale is 1:20. What is the area of the actual room in square feet?

1 answer:

3 0

First, multiply 3.5 by 20 and 2 by 20 to get the real width and length of the room(That would be 70 in. long and 40 in. wide). Then, change that into feet (Which would be 5.8 ft. long and 3.3 ft. wide). Lastly multiply the length by the width. The answer would then be 19.14.

The slope of (17,2) and (18,-17)

Ahat [919]

<u>m= -19/1</u>

We need to use the slope equation

$\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

We are working with the points,

(17, 2) and (18, -17)

x1 y1 x2 y2

$\frac{-17-2}{18-17}$

<u>m= -19/1</u>

Sherry has a package in the shape of a rectangular prism. What is the volume, in cubic inches (in.), of the rectangular prism? (

Rudiy27

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the dimension of the prism is not given. However, the following steps can serve as a guide for you.

The volume of a rectangular prism is calculated as thus:

$Volume = Length * Width * Height$

So, Take for instance

$Length = 2\ in$

$Width = 3\ in$

$Height = 4\ in$

The Volume would be:

$Volume = 2\ in * 3\ in * 4\ in$

$Volume = 24\ in^3$

A and b are positive integers. Find <img src="https://tex.z-dn.net/?f=-2a%2B3b" id="TexFormula1" title="-2a+3b" alt="-2a+3b" ali

lord [1]

A could be 2 while B could be 3, so -2a+3b turns into -4+9, which equals 5.

From what I know you can't really solve a a single equation with two-variables so it's just a matter of trial and error.

Just try plugging in a small number like 2 for a just to try it and you get 8b^2=72.

Divide everything by 8 to isolate b and you get that b^2=9.

Square root everything and you'll find that b=3. This is just one possible combination, I'm sure there are many more but this is obviously the one that was intended to be found.

Now that we know that a=2 and b=3 just plug them into the equation.

-2(2)+3(3)=?

-4+9=?

Sorry about having to use this ^ symbol, the equation maker is not working.
