Since there are 24x-16 total and 3x-2 in each row, we can just divide it to get the number of rows. Since 24/3 and 16/2=8, which is very convenient, we can easily find the number of rows to be 8

Yakvenalex [24]

Answer: 15%

Step-by-step explanation:

They gave their server $8.79 and their total bill was $58.60.

The question wants to know how much percentage of the total bill the tip they gave is:

= Tip / Total bill * 100%

= 8.79 / 58.60 * 100%

= 15%

A sound wave travels at 330m/s and has a wavelength of 2 m. calculate its frequency and period.

RoseWind [281]

Answer:

frequency= 165Hz

period= $\frac{1}{165}$

Step-by-step explanation:

1. To calculate the frequency using the formula:

f = v/λ

where,

f=frequency (what the question asked)

v=speed of wave (given in the question=330m/s)

λ=wavelength (given in the question=2m)

SO,

$f=\frac{330}{2}$

= 165Hz

2. To calculate the period use the formula:

since $f=\frac{1}{T}$

therefore, $T=\frac{1}{f}$

where,

f= frequency (what we solved above=165Hz)

T= period (what the question asked)

SO,

$T=\frac{1}{165}$
