Imagine you have a job where you earn $700 each week after taxes. Your monthly living expenses include $725 for rent, $125 for u

Softa [21]

The monthly income is $844.

Given:

Weekly earning after taxes is $700
Monthly rent is $725
Monthly expense for utilities is $125

Monthly expense for cable/internet is $120

Monthly expense for cellphone is $35

Monthly expense for bus fare is $48

Minimum monthly payment of credit card debt is $78

Monthly expense for groceries is $600

Monthly expense for dining out and entertainment is $225

To find: The monthly income

The monthly income refers to the amount of money left over each month after paying all expenses.

Evaluating, we have,

The total monthly expense = $( $725 + 125 + 120 + 35 + 48 + 78 + 600 + 225$ )

That is, the total monthly expense is $1956.

It is given that weekly earning after taxes is $700. Since a month contains 4 weeks, we can say that monthly earning after taxes is $( $700 \times 4$ ), that is, $2800.

Then, monthly income is given by the difference between the monthly earnings and the monthly expenses. So, monthly income is $( $2800-1956$ ), that is, $844.

The monthly income is $844.

The triangles are similar, find the length of the unknown side. Round your answers to the nearest tenth (0.1), if necessary.

Doss [256]

Answer:

$22$

Step-by-step explanation:

Similar shapes must have corresponding sides in a constant proportion. Therefore, we can set up the following equation and solve for $?$ :

$\frac{28}{42}=\frac{?}{33}$ (divide corresponding sides)

$\frac{28}{42}=\frac{?}{33},\\\\?=\frac{28\cdot 33}{42}=\boxed{22}$

The sum of two numbers is odd. Can the quotient of the two numbers be an odd number?

Natalka [10]

Answer: No.

Step-by-step explanation:

I guess that here we have the statement:

If the sum of two numbers is odd----> can their quotient be an odd number?

first, for n an integer number, we have that:

an odd number can be written as 2n + 1

an even number can be written as 2n.

The sum of two numbers is only odd if one of them is odd and the other even.

Then we have a number that is 2n and other that is 2k + 1, for n and k integer numbers.

Now, let's see if the quotient can also be an odd number.

One way to think this is:

There is an odd number such that when we multiply it by another odd number, the result is an even number?

no, and i can prove it as:

let 2k + 1 be an odd number, and 2j + 1 other.

the product is:

(2k + 1)*(2j + 1) = 2*(2*k*j + k + j) + 1

and as k and j are integers, also does 2*k*j + k + j, so:

2*(2*k*j + k + j) + 1 is an odd number.

This says that the product of two odd numbers is always odd, then we never can have that the quotient between an even number and an odd number is odd.
