Since line m and line n are parallel, that means 45° and (2x-5)° add up to 180°
45+(2x-5)=180
2x-5=135
2x=140
x=70

Anita can clean a typical pool in 8 hours. Chao can clean a typical pool in 6 hours. How long should it take Anita and Chao work
Snezhnost [94]
This kind of problems requires to add the working velocities. The total velocity is the sum of the individual velocities.

Anita's velocity = 1 pool/8 hours
Chao's velocity = 1 pool/6 hours

Combined velocity 1/8 + 1/6 = (3 + 4)/24 = 7/24 pool/hour

Time = 1 pool / (7/24) pool/hour = 24/7 hour =3.43 hours

Need help with this question about amplitude
lesantik [10]

Step-by-step explanation:

the amplitude is the height of the wave.

like with sound - the further away you are, the lower the volume of the sound (as the sound volume is the indicator of the amplitude of a sound wave, or the brightness of a light is the indicator of the amplitude of a light wave).

the same for any other type of wave (like the seismic wave of an earthquake).

so, the larger the distance, normally the smaller the amplitude.
