Paul's budget for food is 30% of the budget he has for rent.

SpyIntel [72]

Paul's rent budget is <u>$750</u>, given that his food budget of $225, is 30 percent of his rent budget.

<h3> What are fractions?</h3>

Fractions are representation of quantities as a part of a certain quantity.

Written as <u>a/b</u>, read as <u>a by b</u>, and functions as <u>a divided by b</u>, represents a fraction showing a parts of b equal parts.

a is called the numerator, and b is called the denominator.

<h3>What are percentages?</h3>

Percentages are modified fractions where the whole quantity is represented by 100.

To convert a fraction into percentages we multiply it by 100, while to convert percentages to fraction divided by 100.

<h3>How to solve the question?</h3>

In the question, we are given that Paul's budget for food is 30% of the budget he has for rent.

We are asked if his budget for food is $225, what is his budget for rent.

We assume Paul's budget for rent to be $x.

We know that Paul's food's budget is 30 percent of his rent.

Hence, Paul's food budget = 30% of x.

or, Paul's budget for food = 30/100 * x {To convert percentages to fraction divided by 100}

But, we know that Paul's food budget is $225. Thus, we can show that:

225 = 30/100 * x,

or, x = (225*100)/30 = 750.

Thus, Paul's rent budget is <u>$750</u>, given that his food budget of $225, is 30 percent of his rent budget.

What’s the answer??(SOMEONE PLEASE HELP ME)

aleksandr82 [10.1K]

We know that According to Algebra of Real Functions :

If f and g are two real functions which are defined under the same domain then $(\frac{f}{g})(x) = \frac{f(x)}{g(x)}$

$\implies Given\;Function\;is\;\frac{-1}{x\sqrt{3x - 9}}$

Now we need find the Domain of this Function :

The Condition for Square Root to be defined is any Expression under it should be Greater than or Equal to Zero.

When Function is a Fraction, it Cannot be defined when the denominator becomes zero. Because when the denominator is zero, the fraction tends to ∞ (because anything divided by zero tends to ∞)

According to Above Conditions Described above, The Given Function is Definable only when the Expression which is under the Square Root is Greater than Zero and x ≠ 0

⇒ 3x - 9 > 0

⇒ 3x > 9

⇒ x > 3

⇒ The Domain of the Given Function is (3 , ∞)

The population of a city in 2005 was 18,000. By 2010, the city’s population had grown to 45,000. Economists have determined that

tensa zangetsu [6.8K]

2005= 18,000
2010= 45,000

1) make 2005 year "0", and 2010 year "5"
2)in order to solve this problem and figure out the rate of change, we must use the equation for exponential functions y=ab^x
3) a= the y- value of y intercept ( what does y equal when x is zero) in this case a population number so, a= 18,000; b= the unknown rate of change; x= time and since we're finding b we can plug in 5 for the time in years; y= the value of y in terms of the x-value, so when x is 5, y is 45,000
4) you end up with something like this
45,000= 18,000b^5
5) in order to proceed to solve you must get b alone
6) divide both sides by 18,000
7) so you no have 2.5= b^5
8) take the fifth root of both sides
9) now you have your answer b=<span>1.20112443398</span>
