Your parents have a realized income of $1,046.78/every 2 weeks. How much should the monthly housing expense budget be to stay wi
IgorLugansk [536]

Answer with explanation:

Income earned by my parents in every two weeks = $ 1046.78

In two weeks there are 14 days, so income earned by my parents in 1 day

              =\frac{1046.78}{14}\\\\74.77

Income of my parents after a month, if there are 30 days in a month = $74.77 × 30= $ 2243.10

We, will use ,\frac{28}{36} rule here , which states that , 28% of monthly income of my parents, should be used for  monthly housing expenses ,and 36% of gross monthly income should be used for debt purposes.

28% of $2243.78

=\frac{28}{100}*2243.78\\\\=\frac{62825.84}{100}\\\\=628.2584

= $ 628.26 (Approx)

So,my parents, monthly housing expense should not exceed ≥ $ 628.26

Sierra says that she can simplify the side of the inequality shown by combining the terms within the parentheses but that she​ c
stiv31 [10]

Answer:

Yes, Sierra is correct

Step-by-step explanation:

Given

4(y + 7) > -3 (4 + 5)

Required

Is she correct

The right parenthesis has 4 + 5.

This can be simplified as: 4 + 5 = 9

So, we have:

4(y + 7) > -3 (4 + 5)

4(y + 7) > -3 *9

The left parenthesis has y + 7.

This cannot be simplified because y is a variable and 7 is a number.

<em>Hence, Sierra is correct.</em>

Suppose you set up a function to show how many hot dogs you will purchase for a dinner when you have already bought two packages
bezimeni [28]

The domain of the function is:

h > 0, only integers.

Then the correct option is the first one.

<h3>What is the domain of the given function?</h3>

For a function f(x), we define the domain as the set of the possible values of x that we can use as inputs in the given function.

Here the function is:

f(h) = 6*h + 12

Where h is the number of packages that you buy.

Then h can be only integers larger than zero (as you can't buy half a package or something like that).

Then we conclude that the correct option is the first option.

If you want to learn more about domains, you can read:
