Answer:
The answer to your question is: I(dB) = 320
Step-by-step explanation:
Data
I(dB) = 10log(
)
I = intensity of a given sound
Io = hearing intensity
if I = 10³²(Io) find I(dB)
Process
Substitute the value of I in the equation given and simplify using logarithms rules.
l(dB) = 
Eliminate Io
I(dB) = 10 log (10³²)
Use the rule of powers in logarithms
I(dB) = 10(32)log(10)
l(dB) = 320(1)
I(dB) = 320
Answer: Both trains would meet at 1 pm
Step-by-step explanation:
Let t represent the time at which both trains will pass each other.
The distance between the cities is 360 miles. This means that by the time both trains meet, the total distance covered would be 360 miles.
Distance = speed × time
The freight train is travelling at 50 mph. Distance covered by the freight train in t hours is 50t.
The passenger train is travelling at 70 mph. Distance covered by the passenger train in t hours is 70t.
Since the total distance covered is 360 miles, it means that
50t + 70t = 360
120t = 360
t = 360/120
t = 3 hours
Both trains would meet at 1 pm
A factor is a number that leaves no remainder behind after it divides the specific number. On the contrary, multiple is a number reached by multiplying a given number by another.
The answers to the given addition operations are
7) 6 Hundredths add to 4 tenths add to 6 ones is equal to 6.46
8) 82 Hundredths add to 9 tenths add to 4 tens is equal to 41.72
<h3>Addition operation </h3>
From the question, we are to add the given numbers
7. 6 Hundredths add to 4 tenths add to 6 ones is equal to
6 Hundredths = 0.06
4 tenths = 0.4
6 ones = 6
Thus, we get
0.06 + 0.4 + 6 = 6.46
8. 82 Hundredths add to 9 tenths add to 4 tens is equal to
82 Hundredths = 0.82
9 tenths = 0.9
4 tens = 40
Thus, we get
0.82 + 0.9 + 40 = 41.72
Hence, the answers to the given addition operations are
7) 6 Hundredths add to 4 tenths add to 6 ones is equal to 6.46
8) 82 Hundredths add to 9 tenths add to 4 tens is equal to 41.72
