(3x - 10) + 45 + (2x + 10) = 180 (the sum of the angles is 180)
3x - 10 + 45 + 2x + 10 = 180
3x + 2x = 180 + 10 - 45 -10
5x = 135
x = 27
3(27) - 10 = 71 (first angle)
2(27) + 10 = 64 (second)
45 (third)
71 + 64 + 45 = 180
0.03
Step-by-step explanation:
S ∝ t, introduce constant, if value of S depends on t only. Let that constant be 'k'.
=> S = kt
When, S = 0.6 & t = 4:
Answer
=> 0.6 = k(4)
=> 0.6/4 = k
=> 0.15 = k
Therefore, when t = 0.2
=> S = kt
= (0.15)(0.2)
= 0.03
3 cats can catch 3 rats in 3 minutes ==> 1 rat per minute.
It takes 3 cats to catch 1 rat per minute.
100 rats in 100 minutes ==> 1 rat per minute
The same <u>3 cats</u> can do it, if they don't wear out and take naps.
30 miles because it is 10 miles per hour.
