Euler's formula is given by:
 C + V = A + 2
 Where,
 C: number of faces
 V: number of vertices
 A: number of edges.
 Clearing A we have:
 A = C + V-2
 Substituting values:
 A = 21 + 14-2
 A = 33
 Answer:
 
the missing number is:

Simplify (0.01)^(-0.5)​
Elena L [17]

Answer:10

Step-by-step explanation:

In fraction,

(1/100)^(-1/2)

Equivalent to 1/((1/100)^(1/2))

Power 1/2 is basically square root

So we have 1/(1/10) after applying square root to 1/100

so final step

1 divide (1/10) = 10

Please help.. nobody will help me and I’ve been asking this question so many times but nobody will answer..

Answer:

The floor covers 81yd^{2}

Step-by-step explanation:

This question is actually easier than you think, but I am here to help.

First off you know the room is a square. All squares have equal sides no matter what, that is the number 1 basic rule. (27ft by 27ft)

1. Find the area of the square: To find area you multiply Length by Width. Since you are multiplying two units you will get a squared value. The square measures 27 ft by 27 ft on both sides.

Lets multiply those two numbers:

(27 * 27) = 729ft^{2}

We need to stay in the same unit because you are multiplying two values of the same unit. The total square feet of the room is 729ft^{2}

2. Next, all you need to do is convert ft^{2} to yd^{2}

Like you mentioned: (1 yd^{2}  = 9ft^{2})

Now lets create a proportion between the two unit:

\frac{729ft^{2} }{1} * \frac{1yd^{2} }{9ft^{2} }

The ft^{2} unit cross cancels and your left with yd^{2}.

Now all you do is multiply straight across and you get \frac{729yd^{2} }{9}  = 81 yd^{2}

They are 4 equal rectangle.

Area rectangle = w * l

5 * 2 = 10 mi² (area 1 rectangle)

then you multiply by 4

10 * 4 = 40 mi²

or

5 * 2 * 4 = 40 mi²
