How long will it take Greg to earn $500.00 round to the nearest hour

Mrrafil [7]

Answer:

56 hours

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

Let

x -----> the number of hours

y ----> the amount earned in dollars

This problem represent a proportional relationship between the variable x and the variable y

Find the value of the constant of proportionality k

$k=y/x$

For (3,27) ----> $k=27/3=9\ \$/h$

For (9,81) ----> $k=81/9=9\ \$/h$

For (21,189) ----> $k=189/21=9\ \$/h$

The constant of proportionality k is 9

The linear equation is

$y=9x$

For y=$500

substitute in the equation and solve for x

$500=9x$

Divide by 9 both sides

$x=56\ hours$

The frequency of the musical note E3 is about 164.81 Hz.

laiz [17]

A perfect fifth above a note has a frequency ratio of 3 to 2.
Therefore, we can set the proportion:
164.81 : x = 2 : 3

which gives:
x = <span>164.81 </span>× 3 ÷ 2
= 247.21

Hence, the perfect fifth above E₃ will have a frequency of 247.21Hz which corresponds to a B₃.
