The decimal of the fraction is .25 or 6/24 :)
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
Answer:
-3.248
Step-by-step explanation:
hope this helps (*^▽^*)
Maybe something like:
200s + 105a + 200 = 1,000
You can use x and y instead of s for student and a for adult.
Are the adults and students charged the same? If so then:
200x + 105x + 200 = 1,000
Pick 1: 3 apples out of 11 pieces of fruit → 3/11
Pick 2: 4 oranges out of 10 pieces of fruit → 4/10 = 2/5
Pick 1 AND Pick 2
3/11 x 2/5 = 6/55
