Answer:
Step-by-step explanation:
8weeeks bc 22.50*8=180
The answer would be 23.6 units
For this case we first write the equation of which we will use:
I (db) = 10log (l / l)
We substitute the value of l.
We have then:
l = 10 ^ 8lo
Substituting in the given equation:
I (db) = 10log ((10 ^ 8lo) / lo)
Rewriting:
I (db) = 10 * log (10 ^ 8)
I (db) = 80
Answer:
I (db) = 80

<span>Choices: 30 units ;
20 units ; 15 units ;
7.5 units
Given:
perimeter = 30 units
scale factor = 0.5
30 units * 0.50 = 15 units
The perimeter of the resulting triangle is 15 units.</span>
Hello!
First you to do 65 * 0.20
0.20 is 20% as a decimal
65 * 0.20 = 13
$13 is how much John saves.
To find out how much the skateboard cost you subtract how much he saved by the cost of the skateboard
65 - 13 = 52
The skateboard cost $52
Hope this helps!
