Answer:
a = -27
d = -21 - ( -27) => 6
a62 => a + 61 (d) +=> -27 + 61(6)
=> -27 + 366
=> 339
Answer:
27.968 mins
Step-by-step explanation:
1) we need to find 8% of 32:
32*0.08=2.56
so 8% of 32 is 2.56 mins.
we need to subtract 2.56 by 32 since its says the times was cut by 8%
so
32-2.56=29.44
now 5% of 29.44:
29.44*0.05=1.472
1.472 mins
so
29.44-1.472=27.968
Hope this helps!
Use the Pythagoras' Theorem:
A^2 + B^2 = C^2
20^2 + 35^2 = C^2
400+ 1225=1625=C^2
square root of 1625= C = 40.31 km
It would be, -12.33-7.21 = -19.54
Hmmmmm....Im guessing in this question you add..When you add it's 35.So I started with 35. Hope this helps! (;
