Answer:
Step-by-step explanation:
10+20+40=70
70*0.8=7*10*0.8=56 L (We Deliver)
total area =2*(10+20)*40+2*10*20=2*30*40+400=2400+400=2800 cm^2
2800*0.02=28*100*0.02=28*2=56 L (Go Parcels)
2/4 - 3/4 = -1/4 hope this helps...
Answer:
18
Step-by-step explanation:
You can see from the table that 2 bracelets are made every 30 minutes.
There are 9 intervals of 30 minutes each in 4.5 hours.
So, the number of bracelets that are made in 4.5 hours is
9x2=18
Another way to see this is to note from the table that 4 bracelets are made in 60 minute, which is 1 hour. So, in 4 hours, 16 bracelets will be made. Also, from the table, 2 bracelets are made in 30 minutes, which is 1/2 hour. So, adding up, 18 bracelets are made in 4.5 hours.
