Lin bought 1 pretzel from a snack cart that was marked $4.50. Why did she pay $4.83?

marshall27 [118]

Answer:

Sales tax

Step-by-step explanation:

You might have like 3% sales tax which is 3 percent of the original price added back onto it.

Sales tax is a tax that is put onto wanted and gourmet things, so chocolate isn't a needed item in life, so you have sales tax on it. On something like bread or meat, there might not be sales tax since you need food to survive. If something cost $100, and there is 3% sales tax, you will pay 103 dollars since 0.03 of 100 is 3.

Which of the following intervals represents the set (1,4) u [2,6]?

fenix001 [56]

Set is a sum of two intervals :(1,4) u [2,6]
In the first interval it is open on both sides so 1 and 4 don't belong to this interval, the second is closed so both 2 and 6 belong to interval and numbers between 2 and 6
We can write it as 1<x $\leq 6$
summing both sets we have one set: (1,6]
so
a) represent our set
b) also represent because all numbers between 4-6 and 6 are in our set
c)also represent, all numbers are in main set
d)also represent

Select the correct answer from each drop-down menu.

RSB [31]

Evidence are simply facts to support a claim, while counterexamples are instances to show the contradictions in a claim

The question is incomplete, as the required drop-down menus are missing. So, I will give a general explanation

To show that a statement is true, you need evidence.

Take for instance:

$\mathbf{if\ a^2 = 4,\ then\ a = 2}$

The evidence that the above proof is true is by taking the squares of both sides of $\mathbf{a = 2}$

$\mathbf{a^2 = 2^2}$

$\mathbf{a^2 = 4}$

However, a counterexample does not need a proof per se.

What a counterexample needs is just an instance or example, to show that:

$\mathbf{if\ a^2 = 4,\ then\ a \ne 2}$

An instance to prove that: $\mathbf{if\ a^2 = 4,\ then\ a = 2}$ is false is:

$\mathbf{a = -2}$

Hence, the complete statement could be:

In a direct proof, evidence is used to support a proof . On the other hand, a counterexample is a single example that shows that a proof is false.

The expression 0.00222 x 10^n is greater than 2 (and n is an integer). what is the smallest possible value for n

77julia77 [94]

The smallest value for n is -3
When you move the decimal point to the right, the exponent on the 10 will be negative
move the decimal point to the right 3 times and you get 2.22 x 10^-3
2.22 is greater than two

Jordan spent 22% of his time doing math homework. If hw spent 11 minutes on his math homework. How many minutes did he spend on

Angelina_Jolie [31]

Jordan spends 50 minutes on his homework.

Step-by-step explanation:

Given,

Time spent on Maths homework = 11 minutes

This represents the 22% time of his total homework.

Let,

x be the total time spent on homework.

22% of x = 11

$\frac{22}{100}*x=11\\0.22x=11$

Dividing both sides by 0.22

$\frac{0.22x}{0.22}=\frac{11}{0.22}\\x=50$

Jordan spends 50 minutes on his homework.
