Sound travels about 340 m in one second. how far would sound travel in a minute and a half? express your answer in scientific notation.

sound will travel 30,600 meters in a minute and a half

Step-by-step explanation:

basically you are going to multiply how many meters sound travels in a second by 90 seconds which is also equal to a minute and a half

to make sure the answer is more accurate use a calculator

the answer is 30,600 meters

-2 is the right

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
