a diver is swimming at -10 m. He then descends 3m and rises 6m. At what new level is the diver swimming?

2 answers:

7 0

So we start at -10. Because he descends 3 feet, We subtract 3, getting -13. He then rises 6 feet. -13 + 6 = -7. The diver is now at -7 feet.

The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as L=10logl/

matrenka [14]

Answer:

The the loudness heard by the mower will be 4 times the loudness heard by the Brandon.

Step-by-step explanation:

The least intense sound a human ear can hear , $I^o=10^{-12} dB$

The sound intensity level that Brandon can hear ,I= $10^{-10} dB$

$L=10\log\frac{I}{I^0}=10\log\frac{10^{-10} dB}{10^{-12}dB}=20$

The sound intensity level of the mower that Ahmad ,I'= $10^{-4} dB$

$L'=10\log\frac{I'}{I^0}=10\log\frac{10^{-4} dB}{10^{-12}dB}=80$

So, the:

$\frac{L}{L'}=\frac{20}{80}=\frac{1}{4}$

$L'=4\times L$

The the loudness heard by the mower will be 4 times the loudness heard by the Brandon.

One timer is set to ring every 48 seconds. Another timer is set to ring every 2 minutes 15 seconds. They rang together at 7 p.m.

Levart [38]

Answer:

8:16 p.m.

Step-by-step explanation:

You have to find LCM(a,b), where a=48 seconds and b=95 seconds (2 minutes 15 seconds).

$48=2\cdot 24=2\cdot 2\cdot 12=2\cdot 2\cdot 2\cdot 6=2\cdot 2\cdot 2\cdot 2\cdot 3=2^4\cdot 3.$

$95=5\cdot 19.$

$LCM(48,95)=2^4\cdot 3\cdot 5\cdot 19=4560\text{ seconds }=76\text{ minutes }=1\text{ hour }16 \text{ minutes. }$

If they rang together at 7 p.m, then the next time that the timers will ring together will be after 1 hour 16 minutes that is 8:16 p.m.
