What is the volume of a room 84 feet long, 48 feet wide and 28 ft high

112,896 ft. cubed

Step-by-step explanation:

Volume is length times width times height. We have all three measures. 84*48*28 equals 112,896. Becuase we are solving for volume, the unit of measure has to be cubed (to the square root of 3). Therefore, the volume of the room is 112,896 ft. cubed.

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
