What is the definition of principal square root in math?
Final answer:
The principal square root in math refers to the positive square root of a number. It is denoted as √x and is applicable to non-negative numbers.
Explanation:
The principal square root in math refers to the positive square root of a number. It is denoted as √x, where x is a non-negative number.
For example, the principal square root of 25 is √25 = 5 because 5 multiplied by itself equals 25.
The principal square root is only applicable to non-negative numbers, while negative numbers have no real square roots.
A color printer prints 24 pages in 7 minutes. how many pages does it print per minute?
Final answer:
The color printer prints approximately 3.43 pages per minute. This is calculated by dividing the total number of pages (24) by the total printing time in minutes (7).
Explanation:
To calculate the number of pages a color printer prints per minute, we use the information provided that it prints 24 pages in 7 minutes. The calculation is a simple division problem:
Determine the rate by dividing the total number of pages by the total number of minutes.Pages per minute = Total pages printed ÷ Total minutesPages per minute = 24 pages ÷ 7 minutesCalculate the quotient to find the page rate.Pages per minute ≈ 3.43 pages per minuteTherefore, the printer prints approximately 3.43 pages per minute.
What is the length of BC¯¯¯¯¯ ?
Enter your answer in the box.
Answer: The required length of BC is 22 units.
Step-by-step explanation: We are given to find the length of BC from the figure.
From the figure, we note that ABC is an isosceles triangle, with AC = AB, where
AC = 2x-24, AB = x-2 and BC = x.
Since AC = AB, so we get
[tex]2x-24=x-2\\\\\Rightarrow 2x-x=24-2\\\\\Rightarrow x=22.[/tex]
Therefore, we get
BC = x = 22.
Thus, the required length of BC is 22 units.

find the slope of a line whose equation is 3X+6Y=9
To find the slope of the above equation, it is easiest to put it into slope-intercept form, y=mx + b, where the variable m represents the slope. To do this, we must isolate the variable y on the left side of the equation by using the reverse order of operations. First, we should subtract 3x from both sides of the equation.
3x + 6y = 9
6y = -3x + 9
Next, we should divide both sides of the equation by 6 to undo the coefficent of 6 on the variable y.
y = -1/2x + 3/2
Therefore, the slope of the line is -1/2 (the coefficient of the variable x in slope-intercept form).

Sondra lives in Nebraska and pays 5.5% in sales tax. If she just bought a belt that cost $22, what was the total amount she paid for the belt, including sales tax?
A.$12.10
B.$20.79
C.$34.10
D.$23.21
please help
5.5% = 0.055
22 * 0.055 = 1.21
22 + 1.21 = 23.21
Answer is D
Answer:
D. $23.21
Step-by-step explanation:
We have been given that Sondra lives in Nebraska and pays 5.5% in sales tax. She just bought a belt that cost $22.
The total amount paid by Sondra for the belt will be equal to cost of belt plus 5.55 of the cost of the belt.
[tex]\text{Total amount paid by Sondra}=\$22+(\frac{5.5}{100}\times \$22)[/tex]
[tex]\text{Total amount paid by Sondra}=\$22+(0.055\times \$22)[/tex]
[tex]\text{Total amount paid by Sondra}=\$22+\$1.21[/tex]
[tex]\text{Total amount paid by Sondra}=\$23.21[/tex]
Therefore, the total amount paid Sondra for belt is $23.21 and option D is the correct choice.
Solve the equation for x. Round your answer to the nearest hundredth.
0.63 = log x
The value of x is:
4.27
Step-by-step explanation:
We have to solve:
logx=0.63
Taking antilog on both sides,we get
x= [tex]10^{0.63}[/tex]
⇒ x=4.2657
Hence, the value of x is:
4.27

The Griffins and the Corbins live in the same city and pay the same sales tax rate, and both families made $12,000 in taxable purchases last year. If the Griffins made $73,000 and the Corbins made $29,000 last year, is the sales tax in their city an example of a regressive tax?
A.Yes, because the Corbins paid a higher percentage of their income in sales tax than the Griffins did.
B.No, because the Corbins paid a higher percentage of their income in sales tax than the Griffins did.
C.No, because the Griffins and the Corbins both paid the same sales tax rate.
D.Yes, because the Griffins and the Corbins both paid the same sales tax rate.
Answer:
The correct answer is A.
Step-by-step explanation:
A.Yes, because the Corbins paid a higher percentage of their income in sales tax than the Griffins did.
Regressive tax is applied uniformly and this causes lower-income people to pay a larger share of their income than rich people. It is not a fair way though it seems to be. Most regressive taxes are not income taxes.
