Answer:
40×3 =120
2×60=120
Step-by-step explanation: have a good day
Speed = 225 metres per minute
Distance = 15 km = 15,000 metres
---------------------------------------------------
s=d/t
ts=d
Therefore: t=d/s
--------------------------------------------------
Time = Distance / Speed
Time = (15,000 metres) / (225 metres per minute)
--------------------------------------------------
Let's work it out:

Answer:
-1 out of -3-X2-4x
Step-by-step explanation:
That is a simple polynomial addition:
(7w3-4w+3)+(5w3-3w-3)
= <span>(7w^3 - 4w + 3) + (5w^3 - 3w - 3)
= </span>7w^3 - 4w + 3 + 5w^3 - 3w - <span>3
= 12w^3 - 7w
= w(</span><span>12w^2 - 7</span>)
Answer:
g(n) =0.05*2ⁿ
Step-by-step explanation:
For each fold, the thickness increases by a factor of 100%. With that in mind, as consecutive folds are made, thickness will grow exponentially. If the initial thickness is 0.05, the thickness 'g' as a function of the number of folds 'n' can be described by:

Assuming infinite folds are possible, the thickness is given by g(n) =0.05*2ⁿ.
