Answer:
he swam on average, 90 yards per minute.
Answer:
(x + y)^5.
Step-by-step explanation:
The (r+1)th term of (x + y)^n = nCr x^n-r y^r
Compare this with 10x^3 y^2 we get
nCr = 10 , n-r = 3 and r = 2 giving n = 3+2 = 5
5C2 = 10.
So the answer is (x + y)^5.
Answer:
2
Step-by-step explanation:
I did this yesterday.
Ratios have no units (as long as both numbers start out with
the same individual units), so the ratio doesn't depend on
the units (as long as both numbers start out with the same
individual units).
The ratio is still 13 to 4 , whether the top and bottom are both
converted to feet, Ångstroms, nanometers, inches, kilometers,
miles, or light-years.
Answer:
If you add the same unknown to the triple unknown you will get 485 finds unknown.
