Which statements about sound waves are true? Select all that apply.
A. The same time it takes for sound to travel is NOT proportional to the distance
traveled by the sound waves.
B. It takes approximately 5 seconds for sound to travel 1 mile.
C. Sound travels at a speed of approximately 0.2 miles per second.
D. The distance traveled by sound waves increases at a constant rate of 0.25 miles for
each 1-second increase in time.
E. In 2.5 seconds, sound can reach a point of about 0.5 miles away.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

its a, i had the same answer, its from study island right
