Answer:
36
Step-by-step explanation:
for the equation, we have to add 1 cubed, 2 cubed and 3 cubed together to get the answer. That equation would look like this
1^3 + 2^3 + 3^3
or expanded out
(1x1x1)+(2x2x2)+(3x3x3)
Solving that down, the equation turns into this
1 + 8 + 27
Adding those values together leaves us with 36!
Hope this helped, have a good rest of your day!
I believe 875 is the answer. That's too high of a score, highest score is like 850.
Answer:
her speed in still water = 11 km/hour
the speed of the current = 9 km/hour
Step-by-step explanation:
x = Ritu's speed of rowing.
y = the sites of the river water flowing
x + y = 20 km / 2 hours = 10 km / hour
x - y = 4 km / 2 hours = 2 km / hour
x = 2 + y
2 + y + y = 20
2y = 18
y = 9 km/hour
x = 2 + y = 2 + 9 = 11 km/hour
