Arectangular picture 16 inches by 20 inches has a frame of uniform width. find the width of the frame if the total area of the picture and the frame is 672 square inches

22

Step-by-step explanation:

The area of the picture =l×b = 20×16=320

The length of the frame is 16

If the width is x ( and it's uniform)

672- 320= 352

Area of the frame = 16× x=352

x=352/16

x = 22

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
