Answer:
D
Step-by-step explanation:
No because
36 / 9 = 4
20 / 4 = 5
So they are multiplied by different amounts so they aren’t equivalent
Solution
For this case we need to find the number of cubes in the stack given so then we can do this:
The first line present 5 cubes
The second line present 5 cubes
And the last line we got:
10 cubes
Then the total of cubes are:
10 +5+5 = 20 cubes
If we need to find the number of faces we can do the following:
5+ 4+ 4+4 +4 +1 + (5+4+4+4+4+1 ) + (5+4+4+4+4+1 ) + (5+ 4+4+4 +4 )
And solving we got:
22+22+ 22+21= 87
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
option 4
Answer:
103
Step-by-step explanation:
your friend's score=x
twice your friend's score=2*x
then your score=6+2*x
Given that your score is=212
In other words, 6+2*x=212
2*x=212-6
2*x=206
x=206/3
x=103
