Answer:
540 mm
Step-by-step explanation:
Here we are given a rectangular box with dimensions of the top surface as 40 mm and 230 mm
We are asked to determine the measurement of the ribbon which may go all the way around the edge of it. Basically we are being asked the perimeter of the top surface. The perimeter is given as the
P=2 (l+w)
l = 230
w = 40
P=2(230+40)
P=2 x 270
P= 540
Hence we need 540 mm of ribbon to go all the way around the edge of the top of the box.
2.25h(60m/hr)(1/3)=45m
So Rick spends 45 minutes studying math per night.
-1*x^2= -1
-1*(1)^2
-1*1= -1
