Answer:

The percent that represents the model is 63%

Step-by-step explanation:

The model is 100 squares, correct? Well, there are 63 shaded. We can easily put that into a percent because percents are always out of 100. In other words, if there was X/100, the X would be the percent. In this case, 63 is in the X spot because that is how many there are shaded, which makes the percent 63%.

Hope this helps <3

Which expression is equivalent to log Subscript c Baseline StartFraction x squared minus 1 Over 5 x EndFraction?

Harrizon [31]

The equivalent expression of $\log_c(\frac{x^2 - 1}{5x})$ is $\log_c(x^2 - 1) - \log_c(5x)$

<h3>How to determine the equivalent expression?</h3>

The logarithmic expression is given as:

$\log_c(\frac{x^2 - 1}{5x})$

The law of logarithm states that:

log(a) - log(b) = log(a/b)

This means that the expression can be split as:

$\log_c(\frac{x^2 - 1}{5x}) = \log_c(x^2 - 1) - \log_c(5x)$

Hence, the equivalent expression of $\log_c(\frac{x^2 - 1}{5x})$ is $\log_c(x^2 - 1) - \log_c(5x)$

Paula a college student earned $3,600 one summer during the following semester she spent $2500 for tuition $650 for rent and $43

Fed [463]

The fraction you are looking for is expenses/earnings

So (2500+650+434)/3600
=224/225

If you want to turn this into a percentage just multiply by 100, to give you 99.56%.
