Product A= 8oz = 1.36 x 2= 2.72. 16oz = 2.72
product B= 16oz= 3.20
so Product A has the lower unit price.
Speed = Distance / Time
Distance = Speed*Time
For this problem, we should bear in mind that current speed has an impact on the boat speed...
for upstream, the boat goes against the current, and so its speed is
U = V - C
where V is the speed of the boat
C is the current speed
for downstream, it will be:
D = V + C
Convert the problem into mathematical equations:
4D + 3U = 116
3D + 4U = 108
4(V+C) + 3(V-C) = 116
4V + 4C + 3V -3C =116
7V + C = 116
3(V+C) + 4(V-C) = 108
3V + 3C + 4V - 4C = 108
7V - C = 108
Solving the equations:
7V + C = 116
7V - C = 108
14V = 224
V = 16km/hr —-> speed of boat
to get C:
7(16) + C = 116
C = 4km/hr
Answer:
There is 9 gifts packets on the shelf.
Step-by-step explanation:
"o" represents a not yellow gift packet and "i" represents a yellow packet.
It says "One of the yellow packets is the sixth from the left" so we have
???iooooo
then it says "the other packet is the eighth from the right" AND "Between the two yellow gift packets there are three differently colored packages"
So we have
oooioooio because there is no "17" answer so it can't be
oooooooioooiooooo
Answer:
-19 ½
Step-by-step explanation:
6 × -3 = -18
½ × -3 = -1 ½
-18 + -1 ½ = -19 ½
