6) Candace Parker bought some new furniture for her house. Tax was included in the price
of the furniture. She bought a chair for 213 dollars, a couch for $812.50, and a television
for $499.99. If she left a 15% tip on the final price of all the furniture how much would
she have paid in total for the furniture and the tip?
ning Carmelo Anthony
Answer:
$1,754,31
Step-by-step explanation:
Furniture = $213 + $812.50 + $499.99 = $1,525.49
15% * $1,525.49 = $228.82
Total = $1,525.49 + $228.82 = $1,754,31
Candace should have gone to Wayfair

a) 314.285728572857.......
b) i think 5.4 boxes
c) its an under estimate cuz actual value is more than 5
Step-by-step explanation:
a) To find the area of her garden, you need to know the area of a circle: πr²
diameter = 20m
radius = 10m
3.14 × 10² = 314m²
b) If 1 box covers 58m², then we need to work out how many 58m² can fit into her garden, but because its an estimate we round the numbers to 1 significant figure
314 ÷ 58 ≈ 300 ÷ 60 = 5
c) The answer is an underestimate because the actual value is 5.4137...
314 ÷ 58 = 5.4137..

A human hair is approximately 40 microns (um) wide. If 1 um is equal to 10
-6
meters (m),
and 1 nanometer (nm) is equal to 10-9m, then how many nanometers wide is a human hair?
A
0.0004 nm
B
0.004 nm
C
4,000 nm
D
40,000 nm
Answer:
D 40,000nm
Step-by-step explanation: 1nm/10^-9m * 10^-6/1um = 10^3 nm/um
Therefore in 40 microns there are:
40um * 10^3 nm/um = 40 * 10^3 nm = 40,000 nm
The human hair is 40,000 nanometers wide.
Option D is the correct answer.
Given,
A human hair is approximately 40 microns (um) wide.
1 um is equal to [tex]10^{-6}[/tex] meters (m)
1 nanometer (nm) is equal to [tex]10^{-9}[/tex] m.
We need to find how many nanometers wide is human hair.
How do we add exponents?We can add the exponents if we have the same base.
Example:
a² x a³ = [tex]a^{(2+3)}[/tex] = [tex]a^{5}[/tex]
[tex]a^{-2}[/tex] x [tex]a^{-3}[/tex] = [tex]a^{(-2 +( -3))}[/tex] = [tex]a^{-5}[/tex]
We have,
Human hair = 40 microns (um) wide.
And,
1 um = [tex]10^{-6}[/tex] m
1 nm = [tex]10^{-9}[/tex] m
[tex]10^{-9}[/tex] m = 1 nm
Multiplying by 10³ on both sides.
[tex]10^{-9}[/tex] x 10³ = 10³ nm
[tex]10^{(-9+3)}[/tex] = 10³ nm
[tex]10^{-6}[/tex] m = 10³ nm
1 um = [tex]10^{-6}[/tex]m
1 um = 10³ nm
Human hair = 40 um
1 um = 10³ nm
Multiplying 40 on both sides.
40 x 1 um = 40 x 10³ nm
40 um = 40 x 1000 nm
40 um = 40,000 nm
Thus human hair is 40,000 nanometers wide.

What’s the domain and range of f(x) = 72 - 1/6x?
Answer:
Step-by-step explanation:
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. A rational function is a function of the form f(x)=p(x)q(x) , where p(x) and q(x) are polynomials and q(x)≠0 .

how to use solution of an inequality in the real world?
They seek to describe the way nature flows. Many of the simpler equations also describe financial concepts, like exponential growth. Exponential growth can describe the cultivation of microorganisms as well.
Addition and substraction is used in shopping.
Much of mathematics are also used in programming in order to make smart software.
You basically used equations everyday without even notice. Like when you have to calculate “How many dollars does the sum of your grocery stuffs equal to?”. Or a more complicated situation, if you need to be in the meeting at 9:30am, the travel distance is 10km and you can only leave after 8:30am, your driving speed should equal “x” km/h.”
Inequalities are used for comparison. “He is taller than me.” or “The iPhone with larger memory capacity is more expensive.”. A more complicated example is also with calculating your driving speed. “Now if there is expected traffic jam for 2km. You get out of the traffic jam at 9:00am, you have to drive faster than
“x” km/h to compensate for your loss time.”
Just some simple examples. There are a lots more out there, just look around.

Using the discriminant, determine the number of real solutions,
-2x^2+x-28= 0
Ono real solutions
O one real solution
O two real solutions
The number of real solutions is 0, the correct answer is A.
How to use discriminant to find the property of solutions of given quadratic equation?Let the quadratic equation given be of the form ax^2 + bx + c = 0, then
The quantity b^2 - 4ac is called its discriminant.
The solution contains the term [tex]\sqrt{b^2 - 4ac}[/tex] which will be:
Real and distinct if the discriminant is positive
Real and equal if the discriminant is 0
Non-real and distinct roots if the discriminant is negative
There are two roots of a quadratic equations always(assuming existence of complex numbers). We say that the considered quadratic equation has 2 solution if roots are distinct, and have 1 solutions when both roots are same.
We are given that;
The equation -2x^2+x-28= 0
Now,
The discriminant of a quadratic equation ax^2 + bx + c = 0 is given by b^2 - 4ac. The discriminant can be used to determine the number of real solutions of the equation as follows:
If the discriminant is positive, there are two distinct real solutions.
If the discriminant is zero, there is one repeated real solution.
If the discriminant is negative, there are no real solutions.
In this case, the quadratic equation is -2x^2 + x - 28 = 0. Comparing it with the standard form, we can identify that a = -2, b = 1, and c = -28. Therefore, the discriminant is:
b^2 - 4ac
= 1^2 - 4(-2)(-28)
= 1 - 224
= -223
Since, the discriminant is negative, there are no real solutions for this equation.
