A building manager is installing a fire alarm that must be heard from three different rooms equally on the first floor of the building.
Consider the graph of the locations of the three rooms.
Room 1
Room 2
Room 3
Where should the building manager place the fire alarm so that it can be heard by all three rooms equally?
The building manager should place the fire alarm at the triangle's circumcenter, which is approximately located at point (2-2).

stop using this to cheat on home work

step-by-step explanation:

dfbvfvdf

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
