Answer:

the tax on a $90,000 salary is: $5175

Step-by-step explanation:

Given that the person earns a $90,000 annual salary, you need to use the last of the brackets , the one that reads "<em>17,001 and up</em>". That is, you need to find the 5.75% of the $90,000 in order to determine the taxes owed.

Recall that 5.75% in math terms is: 5.75/100 = 0.0575

Then the 5.75% of $90,000 is mathematically calculated as the product :

0.0575 x 90,000 = 5175

Therefore the tax on a $90,000 salary is: $5175

nasty-shy [4]
Hello! To solve this question, you'll need to set up a ratio to represent this problem. If there are 6 people who have flu-like systems for every 1 person who has the flu, the ratio would be 6:1. Use this ratio to find the number of patients with only flu-like symptoms.
6 (flu-like symptoms) : 1 (flu)
12:2
18:3
24:4
30:5
36:6
There would be approximately between 30-36 patients with only flu-like systems. Hope this helps! :)

5. What is the probability that a number picked from the set {-4,-3,-2,-1,0,1,2,3,4,5) will be a
tatiyna

Answer:

70%.

Step-by-step explanation:

Rearrange the inequality to isolate x. Start by subtracting 5 from both sides of the inequality:

2\,x + 5 - 5 > 1 - 5,

2\, x > -4.

Divide both sides by 2. (Keep in mind that if the multiplier or divisor is smaller than zero, it will flip the inequality sign.)

x > -2.

There are ten numbers in this set. Only seven of them will satisfy this inequality. Note that the ">" symbol means strictly greater than (while "\ge" means greater than or equal to.) As a result, x = -2 will not count as a solution.

Assume that the number is picked randomly.

\begin{aligned}&\text{Probability of Success} \cr = & \dfrac{\text{Number of Choices that lead to Success}}{\text{Number of all Choices}} \cr =& \dfrac{7}{10} \cr = &0.7 \cr =& 70\% \end{aligned}.
