For S if the ratio is 2:7 and you use 20 drops of red paint you multiply 2 by 10 which is 20 so you also multiply 7 by ten to get 70 (So the answer for S is 70 drops) and for L you multiply 2 by 20 to get 40 so you multiply 7 by 20 and you get 140 (The answer for L is 140 drops) For T you multiply 2 by 1.5 to get 3 so you multiply 7 by 1.5 which is 10.5 ( so the answer for T is 10.5 drops)
For this case, the first thing you should do is observe the graph.
We have that the x-axis represents the intensity of the sound.
The y-axis represents the measure in decibels.
We have then:
For x = 500 the value of y is y = 28
Answer:
The decibel measurement for the quiet room is:
28 decibels
The length of diagonal EK is sqrt(5^2 + 4^2) ≈ 6.403m
Hence perimeter = 2*(12 + 6.403) → 36.8 m (to the nearest tenth of a metre)
Well I think since tim Allen is cool your correct
3(13-2a)=-3+a
39-6a=-3+a
42=7a
a=6
