Nancy had $ 250 at the start when she did not buy anything given by the equation $ 100 = 2 x / 5
Let the original amount Nancy have first be x.
Therefore, Money spent on dress = x / 5
Remaining money = x - x / 5
= 4 x / 5
Money spent on handbag = (1 / 4) × 4 x / 5
= x / 5
Total total money spent is given by the equation:
= x / 5 + x / 5 = $ 100
$ 100 = 2 x / 5
2 x = $ 500
⇒ x = $ 500 / 2
⇒ x = $ 250
Hence, Nancy had $ 250 at the start when she did not buy anything given by the equation $ 100 = 2 x / 5

What is 5 1/3 PERCENT as a fraction in simplest form?
In simplest form, I believe it would be 4/75.
Prove that math is an art and not science.
Can someone help wit this problem I’m confused on it
Answer:
1/9
Step-by-step explanation:
When the quantities are proportional, you are able to find the constant of proportionality by y/x. If you take each one of the y's listed and divide it by x, you will get 1/9.
For example 1 2/9 ÷11
1 2/9 is the same at 9/9 + 2/9 or 11/9
[tex]\frac{11}{9}[/tex] ÷ 11 is the same as [tex]\frac{11}{9}[/tex] ÷ [tex]\frac{11}{1}[/tex] To divide with fractions, you multiply by the reciprocal.
[tex]\frac{11}{9}[/tex] x [tex]\frac{1}{11}[/tex] The 11 can cancel out and we are left with [tex]\frac{1}{9}[/tex]
Answer: r = [tex]\frac{1}{9}[/tex]
Step-by-step explanation:
y = rx
finding r (substitute y and x):
5 = r x 45
5/45 = r
r = [tex]\frac{5}{45} = simplify = \frac{1}{9}[/tex]
checking:
rx = y
[tex]\frac{1}{9}[/tex] x 11 = 1 [tex]\frac{2}{9}[/tex]
[tex]\frac{11}{9}[/tex] = 1 [tex]\frac{2}{9}[/tex]
convert mixed fraction into improper fraction
[tex]\frac{11}{9}[/tex] = [tex]\frac{11}{9}[/tex]

Anumeha is mowing lawns for a summer job. For every mowing job, she charges an initial fee of $10 plus a constant fee for each hour of work. Her fee for a 5-hour job, for instance, is $35
Let y represent Anumeha's fee (in dollars) for a single job that took x hours for her to complete.
The equation that can represent the fee for x hours is y = 10 + 5x.
What is an equation?A mathematical equation that represents the relationship of two expressions on either side of the sign.
We have,
Initial fee = $10
Let the constant fee for each hour of work = M
Fee for 5 hours of work = $35
Every mowing job for 5 hours = Initial fee + constant fee for 5 hours
$35 = $10 + M x 5
35 = 10 + 5M
25 = 5M
M = 5
So,
If y represents Anumeha's fee (in dollars) for a single job that took x hours for her to complete.
We can write an equation as:
y = 10 + 5x
Thus the equation that can represent the fee for x hours is y = 10 + 5x.

A spherical tank has a capacity of 750 gallons. Using the fact that one gallon is about 0.1337 , find the radius of the tank to the nearest hundredth of a foot.
The radius of the spherical tank of capacity 750 gallons to the nearest hundredth is 2.88 ft.
How much s a gallon?
In both imperial and US customary units, the gallon is a unit of volume. The imperial gallon (imp gal), which is or was used in the United Kingdom, Ireland, Canada, Australia, New Zealand, and some Caribbean countries, is defined as 4.54609 liters; the US gallon (US gal), which is used in the US and some Latin American and Caribbean countries, is defined as 3.785411784 L[1] (231 cubic inches); and the US dry gallon ("usdrygal"), which is defined as 18 US bushel (exactly 4.40488377086 L).
Given data: 1 gallon ≈ 0.1337 ft³
Then, 750 gallons = 0.1337 x 750 ≈ 100.275 ft³
We know, Volume of sphere, [tex]V=\frac{4}{3}\pi r^{3}[/tex]
then, r = [tex]\sqrt[3]{\frac{3}{4\pi }V }[/tex]

b) The average rate of change was of -328.5 habitants per year between 2002 and 2004.
c) The rate of population increase was greater between 1998 and 2001.
d) The rate of population decrease was greater between 2002 and 2004.
What is the average rate of change of a function?The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
For item a, we have that:
In 1998 the population was of 856.In 2001 the population was of 1591.Hence the rate is:
(1591 - 856)/3 = 245.
The average rate of change was of 245 habitants per year between 1998 and 2001.
For item b, we have that:
In 2002 the population was of 1483.In 2004 the population was of 826.Hence the rate is:
(826 - 1483)/2 = -328.5.
The average rate of change was of -328.5 habitants per year between 2002 and 2004.
Hence:
c) The rate of population increase was greater between 1998 and 2001.
d) The rate of population decrease was greater between 2002 and 2004.

F ' = (0.5, 0.5)
G ' = (0, 0)
D ' = (-1, 0.75)
Notes: 0.5 = 1/2 and 0.75 = 3/4

Explanation:
Assuming the origin is the center of dilation, then we multiply each coordinate by the scale factor of 1/4 = 0.25
For instance, the point E(0,4) moves to E ' (0, 1) since
x coordinate: 0*0.25 = 0y coordinate: 4*0.25 = 1Do the same for the other points.
What are the vertices of this ellipse?
The vertices of the given ellipse are (-9, 2) and (-1, 2). Therefore, option D is the correct answer.
We need to find the vertices of the given ellipse.
What is the vertex of the ellipse?The major axis of the ellipse cuts the ellipse into two distinct points called the vertices of the ellipse. The line perpendicular to the major axis of the ellipse is the minor axis, and it cuts the ellipse at two distinct points called the covertices of the ellipse. The midpoint of the vertices of the ellipse, or the covertices of an ellipse is the centre of the ellipse. The endpoints of the major axis are the vertices, and the endpoints of the minor axis are the covertices.
Equation of the ellipse = x²/a² + y²/b² = 1
Vertices of Ellipse: (a, 0), (-a, 0)
As we know, the endpoints of the major axis are the vertices.
From the given figure we can see that axis of the ellipse passes through the points (-1, 2) and (-9, 2).
The vertices of the given ellipse are (-9, 2) and (-1, 2). Therefore, option D is the correct answer.

Let L be the line that passes through the points with coordinates (1,1) and (-1,3).
(a) Determine the equation (in the form y = mx + b) of the line L.
(b) Determine the equation of the line K that passes through the (0, -1) and is perpen-
dicular to the line L.
(c) Find the coordinates of the point at which the lines and K intersect.
(a). The equation of the line L in the form of y = mx + b is y + 2x = 0.
(b). The equation of the line K that passes through the point (0, -1) and is perpendicular to the line L is y = 2x - 1.
(c). The intersection of the lines and K is located at a location with the coordinates (0,-1).
Define equation of line.The equation of a line has the usual form axe + by + c = 0. Here, x and y are the variables, a and b are the coefficients, and c is the constant term. You may also find and see the equation of a line in the slope-intercept form, point-slope form, two-point form, intercept form, and normal form.
The formula of slope is given by m = (y₂-y₁)/(x₂-x₁).
Here, m is the slope of the line.
(x₁, y₁) and (x₂, y₂) are the two points of the line.
Now put the value of x₁, y₁, x₂, y₂ in
m = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
m = [tex]\frac{3-1}{-1-1}[/tex]
m = 2/-1
m = -2
The slope of the line perpendicular is:
mₐ = - 1/m
mₐ = -1/-2
mₐ = 2
(a) The equation (in the form y = mx + b) of the line L.
(y-y₁) = m(x-x₁)
(y-1) = -2(x-1)
y-1 = -2x-1
y = -2x
y + 2x = 0
(b) The equation of the line K that passes through the (0, -1) and is perpendicular to the line L.
x = 0 and y = -1
y = mx + b
y = 2x + b
-1 = 2×0 + b
-1 = b
b = -1
Substituting the above in y = mx + b to get:
y = mx + b
y =2x + (-1)
y = 2x - 1
(c) The coordinates of the point at which the lines and K intersect.
y = 2x - 1
y+2x+1=0
(2x-1)+2x+1=0
4x =0
x = 0, y = -1

Construct a 95% confidence interval estimate for the mean number of absences for clerical workers during the year. Interpret. (Assume that the population is normally distributed)
The 95% confidence interval estimate for the mean number of absences for clerical workers during the year is (8.132, 11.268).
What is confidence interval?It should be noted that the mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.
Given a = 0.05, Z(0.025) = 1.96 (from standard normal table).
The 95% confidence interval will be:
xbar +/- Z*s/vn
= 9.7 +/- 1.96*4/✓(25)
