Alexa's non-taxable income will be equal to $603.3.

<h3>What is an expression?</h3>

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Alyssa started working making $14.75 per hour. She worked a total of 48 hours during the last pay cycle. Her taxes totalled $104.22.

The non-taxable income will be calculated as,

Total income = 14.75 x 48 = 707.52

Non-taxable income = 707.52 - 104.22

Non-taxable income = $603.3

Therefore, Alexa's non-taxable income will be equal to $603.3.

mr scott rented a bicycle for 6 hours on saturday and then several more hours on sunday. it cost $4 per hour to rent the bicycle

julia-pushkina [17]

Well, we know that he rode it on Saturday for 6 hours, and that it costs $4 per hour. So what we must do is multiply 6 by $4. That gives us 24 dollars. Now, subtract $48 by $24 to get $24. Now you know that he rode 6 hours on Saturday and Sunday.

Find the quotient. Write your answer in standard form. : 3-i/3+i

s344n2d4d5 [400]

The answer is <span>C. 4/5 - 3/5 i
</span>
$\frac{3-i}{3+i} = \frac{(3-i)(3-i)}{(3+i)(3-i)} \\ \\ 
(a+b)(a-b) = a^{2} -b^{2} \\ \\ 
\frac{(3-i)(3-i)}{(3+i)(3-i)}= \frac{ (3-i)^{2} }{3^{2}-i^{2} } \\ \\ 
(a-b)^{2} =a^{2}-2ab+b^{2} \\ \\ 
 \frac{ (3-i)^{2} }{3^{2}-i^{2} } = \frac{3^{2}-2*3*i+i^{2} }{3^{2}-i^{2} } = \frac{9-6i+i^{2}}{9-i^{2}} \\ \\ 
i = \sqrt{-1} \\ i^{2}=-1 \\ \\ 
\frac{9-6i+i^{2}}{9-i^{2}} = \frac{9-6i-1}{9+1} = \frac{8-6i}{10}= \frac{8}{10}- \frac{6i}{10}= \frac{4}{5}- \frac{3}{5}i$
