Which inequality represents the sentence? The difference of seven and two tenths and a number is more than twenty nine. 7. 2 - n > 29 n - 7. 2 Greater-than-or-equal-to 29 7. 2 - n < 29 n - 7. 2 < 29.
The inequality which represent, the difference of seven and two tenths and a number is more than twenty-nine, is
[tex]7.2-n > 29[/tex]
What is the inequality equation?Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.
Inequality is represented with the greater then(<), less then(>) or with the other inequity signs like less than equal to [tex]\leq[/tex] or greater than equal to [tex]\geq[/tex].
Tenth is written as the fractional part of the number 10. The value of one tenth is equal to 1/10 or 0.1.
The sentence given for the inequality expression is, that the differences of seven and two tenths, and a number is more than twenty-nine.
The number seven and two tenths can be written as,
[tex]7\dfrac{2}{10}[/tex]
Suppose the unknown number is n. Now, the differences of seven and two tenths, and this number (n) is more than twenty-nine. The more than word means, the greater than sign for equation. Thus, it can be expressed as,
[tex]7\dfrac{2}{10}-n > 29\\\dfrac{72}{10}-n > 29\\7.2-n > 29[/tex]
Hence, the inequality which represent, the difference of seven and two tenths and a number is more than twenty-nine, is
[tex]7.2-n > 29[/tex]

Yes, they are
Because with fractions, you can divide. The rules for multiplying or dividing with negative numbers are that negative * or / negative = positive and that one negative * or / a positive = negative. These fractions here have one negative and one positive, making it so that when you divide, it will be negative.
Hello.
[tex]\mathrm{\displaystyle\frac{7}{-8} \:and\:\frac{-7}{8} \:are\:equal\:}[/tex]
If we divide a positive number by a negative number, we get a negative number.
Let's try.
We can turn both of these fractions into decimals and see if they are equivalent.
The simplest way to turn a fraction into a decimal is divide the numerator by the denominator.
[tex]\mathrm{\displaystyle\frac{7}{-8} = -0.875}[/tex]
Now, let's convert the second fraction into a decimal:
[tex]\mathrm{\displaystyle\frac{-7}{8} =-0.875}[/tex]
[tex]\mathrm{-0.875=-0.875}[/tex]
Therefore, the two fractions are equivalent (equal).
I hope it helps.
Have a nice day.

At the end of a snow storm, Cameron saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. Let SS represent the depth of snow on Cameron's lawn, in inches, tt hours after the snow stopped falling. The table below has select values showing the linear relationship between tt and S.S. Determine how many hours it would take for the depth of snow to reach 8 inches.
Answer:
A Winter Storm Warning is in effect for all of Western New York through Friday morning/afternoon depending on where you live.
The combination of falling temperatures and increasing snowfall rates will cause extremely slippery roads through the Friday morning commute.
Snowfall rates will be near an inch per hour at times and there will be some blowing and drifting snow. This will reduce visibility, adding another layer of difficulty to the already messy drive.
All across WNY visibility is not great. As we approach rush hour, keep this in mind.
Plan for extra time (double the usual), make sure your lights are on, and leave space between you and the car in front of you! There is nothing worse than tailgaters in a snowstorm.

Arrange the circles (represented by their equations in general form) in ascending order of their radius lengths. X2 y2 − 2x 2y − 1 = 0 x2 y2 − 4x 4y − 10 = 0 x2 y2 − 8x − 6y − 20 = 0 4x2 4y2 16x 24y − 40 = 0 5x2 5y2 − 20x 30y 40 = 0 2x2 2y2 − 28x − 32y − 8 = 0 x2 y2 12x − 2y − 9 = 0.
Circles (represented by their equations in general form) in ascending order of their radius lengths can be arranged as first-fifth-second-forth-third-seventh-sixth.
What is the equation of circle?The equation of the circle is the equation which is used to represent the circle in the algebraic equation form with the value of center point in the coordinate plane and measure of radius.
The standard form of the equation of the circle can be given as,
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Here (h,k) is the center of the circle and (r) is the radius of the circle.
Lets arrange the first equation, in standard form of equation of circle as,
[tex]x^2 +y^2 - 2x+ 2y -1 = 0 \\(x^2 - 2x) +(y^2+ 2y )= 1\\(x^2 - 2x+1) +(y^2+ 2y +1)= 1+1+1\\(x-1)^2+(y+1)^2=(\sqrt{3})^2[/tex]
The radius of this circle is √(3).
Lets arrange the second equation, in standard form of equation of circle as,
[tex]x^2 +y^2 - 4x+ 4y - 10 = 0 \\(x^2 - 4x) +(y^2+ 4y )= 10\\(x^2 - 4x+4) +(y^2+ 4y +4)= 10+4+4\\(x-2)^2+(y+2)^2=(\sqrt{18})^2[/tex]
The radius of this circle is √(18).
Lets arrange the third equation, in standard form of equation of circle as,
[tex]x^2 +y^2 - 8x - 6y - 20 = 0 \\(x^2 - 8x) +(y^2-6y )= 20\\(x^2 - 8x+16) +(y^2- 6y +9)= 10+16+9\\(x-4)^2+(y-3)^2=(\sqrt{45})^2[/tex]
The radius of this circle is √(45).
Similarly, radius of the forth, fifth, sixth and seventh circle is √(23), √(5), √(117) and √(46) units.
Hence, the circles (represented by their equations in general form) in ascending order of their radius lengths can be arranged as first-fifth-second-forth-third-seventh-sixth.

Florian ran 1. 2 miles and walked 4. 8 laps around the path at the park for a total distance of 3. 6 miles. Which shows the correct equation and value of x, the distance of 1 lap around the path at the park? 3. 6 x 1. 2 = 4. 8; x = 1 mile 4. 8 x 1. 2 = 3. 6; x = 1 mile 3. 6 x 1. 2 = 4. 8; x = 0. 5 mile 4. 8 x 1. 2 = 3. 6; x = 0. 5 mile.
The correct equation and value of x, the distance of 1 lap around the path at the park is 4.8x + 1.2 = 3.6. Then the correct option is B.
What is the linear system?It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Florian ran 1.2 miles and walked 4.8 laps around the path at the park for a total distance of 3.6 miles.
This is because lap will be dependent on the variable, we know that the number of them will be multiplied by the variable x we also know that 1.2 miles are constant. Now the equation will be
4.8x + 1.2 = 3.6
Thus, the correct option is B .

Answer for 50 BRAINLIST!!!
Answer:
[tex](2, 4)\rightarrow\text{First system}[/tex]
[tex](4, -2)\rightarrow\text{Second system}[/tex]
Step-by-step explanation:
First system:
We can substitute 2x for y:
[tex]6x-y=8\\6x-2x=8\\4x=8[/tex]
Divide both sides by 4
[tex]x=2[/tex]
Substitute 2 for x to solve for y:
[tex]y=2x=2(2)=4[/tex]
[tex](x, y)=(2, 4)[/tex]
Second system:
We can isolate x in the second equation by subtracting 4y from both sides:
[tex]x=-4-4y[/tex]
Now, substitute this value for x in the first equation:
[tex]3(-4-4y)+5y=2\\[/tex]
Distribute the 3 to each term in the parentheses:
[tex]3(-4)+3(-4y)+5y=2\\-12-12y+5y=2\\-12-7y=2[/tex]
Add 12 to both sides:
[tex]-7y=14[/tex]
Divide both sides by -7
[tex]y=-2[/tex]
Now, substitute -2 for y to solve for x:
[tex]x=-4-4y=-4-4(-2)=-4+8=4[/tex]
[tex](x, y)=(4, -2)[/tex]

In a recursive function, what is used to determine whether to stop or to continue with another recursive step
Recursive functions are functions whose execution is called from within itself
A condition is used to stop or continue another recursive step
When does a recursive function stop?
As implied earlier, the execution of a recursive function is from within the function itself.
This means that the recursive function will continue its execution, until a condition is met.
This condition is used to determine the execution or the termination of the recursive process
Hence, a condition is used to stop or continue another recursive step
