If l = 60 inches, w = 65 inches, h = 50 inches, and t = 40 inches, counting the floor, what is the volume of the tent?
defon

Answer:

To find volume of a tent this would be your formula:

start by taking the base of the triangle on your tent typically located in the front

1/2 (height) (width) to get your area (DONT SKIP THIS STEP)

Then take your area you just calculated and do

(area) (length)

Let me give you an example:

in the picture below

height: 3 cm

length: 8 cm

Width: 12 cm

Next do your first formula:

1/2 (3)(12)= 18 cm

(Calculation of one face)

then your second:

(18)(8)= 144 cm^3}

Hopefully this guide helped you sorry i couldn't answer your question without a picture!

Write a positive or negative integer an increase of $15
slamgirl [31]

Answer:

  +15

Step-by-step explanation:

An increase is generally regarded as being positive. If units are dollars, an increase of $15 can be represented by the integer +15.

__

<em>Additional comment</em>

If units are dimes, then the number would be +150. So, you see, <em>the units are important </em>to know.

It also depends on <em>what is increasing</em> and what is being represented by the integer. If it is an increase in debt, then the change in net worth might be -15.
