Answer:
I don't know if im right but t
o clarify, the m is sometimes used to distinguish between the measure of the angle (m∠ABC = a number, in degrees/radians) and the actual angle itself (the geometric object ∠ABC).
Step-by-step explanation:
Quadrilateral has four sides. Not necessarily a rectangle, just four sides.
They are similar, so the sides of one of them and the other one are in proportion.
We have to find the proportion. Notice that the 12 feet side and the 18 feet side must be the one in common. 3 longest ones ... one is missing, then, two shortest ones ... two are missing, but they must share that one:
The ratio is the 18:12 or 3:2.
Now we can complete both quadrilaterals:
ABCD: 24, 16, 12, ?
EFGH: ?, ?, 18, 9
ABCD: 24, 16, 12, 6
EFGH: 36, 24, 18, 9
24 is the answer!!
Answer:
X=1/4
Step-by-step explanation:
(x+x)*8=4
(2x)*8=4
16x=4
X=4/16=1/4
Answer:
Step-by-step explanation:
Given
--- Intensity
Required
Determine the decibel level (D)
This is calculated as:
Where:
The threshold intensity
So, we have:
This gives:
Apply law of indices
Apply law of logarithm
So, we have:
So:
<em>Hence, the decibel level is 50</em>
