The relationship between a number of decibels β and the intensity of a sound I (in watts per square meter) is β=10log10(I10−12).

The number of decibels for a sound with an intensity of 10−6 watts per square meter is
.
A sound with ten times that intensity has
decibels.
In general, a sound with ten times the intensity of a sound with n decibels has
decibels.
Hint: It may help to use the properties of logarithms to rewrite the equation given in this problem.

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

probably .5

i can on others if necessary.
