Answer:X∧N and Y ∧N share a variable
Step-by-step explanation: X∧N
Y∧N
they have the last same variable
Answer:310
Step-by-step explanation:
l=-1+3w
l=3w-1
l*w=310
(3w-1)*w=310
3w^2-w-310=0
w= 31/3
w= 10 1/3
l=31/3*3-1
l=30
30*31/3=10*31=310
Answer:
169 seconds
3rd lap
0.923 minutes
Step-by-step explanation:
To solve this question, we would use formula for arithmetic progression in solving it.
S(n) = a + (n - 1)d
If a = 25 s
n = 10
d = 16
S(n) = 25 + (10 - 1)16
S(n) = 25 + 9 * 16
S(n) = 25 + 144
S(n) = 169
It takes him 169 seconds to cycle his tenth lap
b
If S(n) = 55.4, what is n
55.4 = 25 + (n - 1)16
55.4 - 25 = (n - 1)16
30.4 = (n - 1)16
n - 1 = 30.4/16
n - 1 = 1.9
n = 1.9 + 1
n = 2.9 approximately 3
Therefore, he's on his 3rd lap
c
Total time cycled is dependent on the total cycles he made, and going to question 2, we were told he made 55.4 seconds of cycle
55.4/60 = 0.923 minutes
