The independent quantity is the height of the baton and the dependent quantity is the seconds she has to twirl.
What is an independent and dependent variable?The independent variable is the variable that the person carrying out an activity can change or manipulate. It is the independent quantity that determines the dependent quantity.
The dependent variable is the variable that is being measured in an experiment. The dependent quantity is usually affected by the independent quantity.
In this question, the height of the baton determines the time she has to twirl. The higher the baton goes, the longer the time she has to twirl. This makes the height of the baton the independent quantity and the time she has to twirl the dependent quantity.

The price of a computer is 899.00 the sales tax rate is 7% what is the sales tax on the computer in dollars and cent
The value of the sales tax on the computer is 62 dollars and 93 cents.
Any number or a ratio which is expressed in terms of a fraction of 100 is known as a percentage.
Here, we are given that the price of a computer is 899 dollars.
The sales tax on the computer is 7%.
Thus, the value of the sales tax on the computer will be,
7% of 899
= 7/100 * 899
= 62.93
Thus, the sales tax on the computer comes out to be 62.93 dollars.
In 62.93 dollars, we can see that we have 62 complete dollars, plus 0.93 more dollars left.
0.93 dollars = 93 cents

4=2x+y
-6x-3y=-12
Elimination
Answer:
infinitely many solutions
Step-by-step explanation:
4=2x+y
-6x-3y=-12
First, line up the variables in the right place
4=2x+y
-12=-6x-3y
Choose the variable you want to eliminate, I will do x
Multiply everything in the first equation by 3
3(4)=(2x+y)3
-12=-6x-3y
Simplify
12=6x+3y
-12=-6x-3y
If we combined everything, it would all cancel
This means there are infinitely many solutions
A sqaure garden has an area of 144 square feet. how many yards of fence will it take to enclose the garden?
The number of yards of fence it will take to enclose the square garden is 48 feet.
It is given in the question that a square garden has an area of 144 square feet.
We have to find the number of yards of fence it will take to enclose the garden.
Let the length of side of the square garden be x feet.
We know that,
Area of a square = [tex]side^2[/tex]
Hence,
According to the data given in the question, we can write,
144 = [tex]side^{2}[/tex]
We know that,
144 = [tex]12^2[/tex]
Hence,
[tex]12^2=side^2[/tex]
Hence,
Side = 12 feet
We know that,
Number of yards of fence it will take to enclose the square garden = perimeter of the square garden.
Hence,
Number of yards of fence it will take to enclose the square garden = 4* side of the square garden = 4*12 = 48 feet.

Point D is 1n of the way from C(−2.5, 1.25) to E(5, 15). What are the coordinates of D if n = 5?
Answer:
Coordinates of D are (-1, 4)
Step-by-step explanation:
I have assumed that what you wrote as 1n is actually 1/n otherwise the question does not make sense
1/n with n = 5 ==> that D is 1/5th of the distance from C on the CD line segment
Point D is 1/5th of the way from C to D
I will represent the (x, y) coordinates of points C, D and E as
[tex](x_C, y_C), (x_D, y_D) , (x_E, y_E)[/tex] respectively
Then the x-distance from C to E = [tex]x_E - x_C[/tex] and the y-distance from C to E will be [tex]y_E - y_C[/tex]
[tex]\text{1/5th of }[/tex] [tex]x_E - x_C = \dfrac{x_E - x_C}{5}[/tex] but this is relative to the location of [tex]x_C[/tex].
So we have to add this to [tex]x_C[/tex] to get the absolute x-coordinate of D
So
[tex]\displaystyle \large x_{D}=x_{C}+\dfrac{x_{E}-x_{C}}{5}[/tex]
and similarly
[tex]{\displaystyle y_{D}=y_{C}+\dfrac{y_{E}-y_{C}}{5}}[/tex]
Putting in the values for these coordinates we get
[tex]x_{D}=-2.5+\dfrac{5-(-2.5)}{5} \\\\= -2.5 + \dfrac{5 + 2.5}{5}\\\\\= -2.5 + \dfrac{7.5}{5}\\\\= - 2.5 + 1.5\\\\= -1.0[/tex]
[tex]y_{D}=1.25+\dfrac{15-1.25)}{5} \\\\= 1.25+ \dfrac{15 - 1.25}{5}\\\\\ = 1.25+ \dfrac{13.75}{5}\\\\= 1.25+ 2.75\\\\= 4.0[/tex]
So the coordinates of D are:
[tex]\boxed{D(-1, 4)}[/tex]
The graph shows the point D is indeed 1/5th of the distance from C to D

The solution set of the inequality is the set of all real numbers larger than 5, written in interval form as (5, ∞)
How to solve the inequality for x?Here we have a simple inequality:
x - 2 > 3
To solve this we need to isolate x in one side of the inequality.
Now, remember that we can do the same operation in both sides of the inequality. So, if we add in both sides the same number, then the truth value of the inequality does not change.
Then if we add 2 in both sides of the inequality we get:
x - 2 + 2 > 3 + 2
x > 5
Then the solution set of the inequality is the set of all real numbers larger than 5, written in interval form as (5, ∞).

Question 4 4.1 Determine the value of c in the diagram. 65% c 4.2 Determine the value in the diagram. x-20° 84° (3) Statement Statement Reason Reason
The value of c is 25° and x is 116°.
From figure 1, we can see hat the entire angle is given to be 90°. This angle is divided into 2 parts, one is 65° and the other is c
This means that-
65 + c = 90
c = 90 - 65
c = 25
Thus, the value of c is 25°.
Now, in the 2nd figure, we can see that both the horizontal lines are parallel and a transversal is drawn between them.
Both the angles thus formed are opposite interior angles and are hence supplementary.
Therefore, (x - 20) + 84 = 180
x - 20 = 180 - 84
x - 20 = 96
x = 96 + 20
x = 116
Thus, the value of x is 116°

If the mean of a normal distribution is 20 and its standard deviation is 3, between which values would 99.5 percent of the data observations be expected to fall?
99.5% of the data observations should fall between 11.579 and 28.421 according to expectations for the given normal distribution.
What is a normal distribution?
A continuous probability distribution for just a real-valued random variable in statistics is known as a normal distribution or Gaussian distribution.
According to the question, if the lower limit is a and the upper limit is b, then 99.5 percent of values fall between a and b.
part of values below a certain threshold, a= (1-0.995)/2 = 0.0025
Mean,m =20
Standard deviation,s = 3
Z = (X – m) / s
P(x<Z): 0.0025
P(x<Z) = 0.0025 can be determined for Z score.
according to the usual table, Z = -2.807
X = Zs+m
(-2.807 * 3) +20= 11.579
Lower limit = 11.579
Part of values that are less than b is equal to 0.995 + 0.0025 = 0.9975.
P(x<Z): 0.9975
Z score for which P(x<Z) = 0.9975 can be found
from the normal table as, Z = 2.807
X = Zs+m
(2.807 * 3) +20= 28.421
Upper limit = 28.421
99.5% of the data observations should fall between 11.579 and 28.421 according to expectations for the given normal distribution.

g(x)=?
The function g whose graph is a translation 3 units up from the graph of F is given as g(x) = -x+6
What is the explanation for the above?Given:
f(x) = -x + 3...............1
Transformation is 3 units up from the graph of F

g(x) = f(x) + 3...........2
Recall that f(x) = -x+3 Hence
Substituting f(x) in to Equation 2

A spherical tank has a capacity of 750 gallons. using the fact that 1 gallon is about 0.1337 ft3, find the radius of the tank (to the nearest hundredth of a foot).
The spherical tank with a capacity of 750 gallons has a radius of 2.88ft.
Volume refers to the total amount of space an object occupies. It also determines the capacity of the object.
Given the fact that 1 gallon is about 0.1337 ft^3, and the spherical tank has a capacity of 750 gallons, then it's volume or capacity can be converted from gallons to ft^3 by multiplying 750 with 0.1337.
1 gallon = 0.1337 ft^3
750 gallons = 750(0.1337 ft^3)
750 gallons = 100.275 ft^3
To solve for the radius of the spherical tank, use the formula for the volume of sphere given by the formula:
V = 4/3πr^3
where V = 100.275 ft^3
100.275 ft^3 = 4/3πr^3
r^3 = 23.93889288 ft^3

A person invests 10000 dollars in a bank. The bank pays 6.5% interest compounded
annually. To the nearest tenth of a year, how long must the person leave the money
in the bank until it reaches 29500 dollars?
The time it will take for the money in the bank to reach a total of 29500 dollars would be = 30 years.
How to calculate the time for the interest compounded annually?To calculate the time for the interest compounded annually the formula below is used:
Simple interest = principal× time×rate/ 100
Simple interest = principal× time×rate/ 100Simple interest = total amount in the bank - principal amount
= 29500 - 10000
= $19,500
Principal = $10000
Rate = 6.5%
Time = ?
From the given formula, make t that subject of formula;
T = $19,500 ×100/$10000×6.5
T = 1950000/65000
