A soccer player has a large cylindrical water cooler that measures 3.5 feet in diameter and is 2 feet tall. If there are approximately 7.48 gallons of water in a cubic foot, how many gallons of water are in the water cooler when it is completely full? Use π = 3.14 and round to the nearest hundredth.
575.44 gallons
143.86 gallons
76.93 gallons
19.23 gallons
There are approximately 205.33 gallons of water in the water cooler when it is completely full.
What is the volume of the cylinder?
The volume of a cylinder is given by the formula:
V = πr^2h
where V is the volume, r is the radius, and h is the height of the cylinder.
The volume of the cylindrical water cooler is:
V = πr^2h
where r is the radius and h is the height. Substituting the given values:
V = 3.14 x (3.5/2)^2 x 2
= 27.44 cubic feet
To convert cubic feet to gallons, we can multiply by 7.48 gallons/cubic foot:
V = 27.44 x 7.48
= 205.32 gallons
Rounding to the nearest hundredth, the answer is:
205.32 ≈ 205.33 gallons
Hence, there are approximately 205.33 gallons of water in the water cooler when it is completely full.

A sample of blood pressure measurements is taken for a group of adults, and those values (mm Hg) are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurement. Find the coefficient of variation for each of the two samples; then compare the variation.

Answer:
To find the coefficient of variation (CV) of a sample, we divide the standard deviation by the mean and multiply by 100 to get the percentage.
1. For the systolic sample:
•Find the mean:
mean = (116 + 130 + 157 + 94 + 155 + 122 + 115 + 138 + 124 + 122) / 10 = 130
•Find the standard deviation:
sum = (116 - 130)^2 + (130 - 130)^2 + (157 - 130)^2 + (94 - 130)^2 + (155 - 130)^2 + (122 - 130)^2 + (115 - 130)^2 + (138 - 130)^2 + (124 - 130)^2 + (122 - 130)^2
sum = 165.4
std = sqrt(sum/9) = 7.3
•Calculate the coefficient of variation:
CV = (std / mean) × 100 = (7.3 / 130) × 100 = 5.62%
2. For the diastolic sample:
•Find the mean:
mean = (82 + 78 + 74 + 51 + 89 + 88 + 56 + 63 + 72 + 83) / 10 = 72.5
•Find the standard deviation:
sum = (82 - 72.5)^2 + (78 - 72.5)^2 + (74 - 72.5)^2 + (51 - 72.5)^2 + (89 - 72.5)^2 + (88 - 72.5)^2 + (56 - 72.5)^2 + (63 - 72.5)^2 + (72 - 72.5)^2 + (83 - 72.5)^2
sum = 624.75
std = sqrt(sum/9) = 12.24
•Calculate the coefficient of variation:
CV = (std / mean) × 100 = (12.24 / 72.5) × 100 = 16.82%
So the CV for systolic is 5.62% and the CV for diastolic is 16.82%. We can see that the diastolic measurement has higher variation than the systolic measurement.

How to calculate the missing lengths in a system of similar triangles
Two triangles are similar if they have congruent angles and if their sides are not congruent though proportional. The statement of the problem can be described by following equations:
Proportion formula
AD / BD = DL / AD
DL = 4 · BD
Then, we find the formula for line segment DL:
AD / BD = 4 · BD / AD
AD² = 4 · BD²
BD = √(AD / 2)

The value of the composite functions of h(g(x)) is h(g(x)) = -20x + 6.
What is composite function?In mathematics, a function is composed when two functions, f and g, are used to create a new function, h, such that h(x) = g(f(x)). The function of g is being applied to the function of x, in this case. Therefore, a function is essentially applied to the output of another function.
Given that, h(x) = 4x + 6 and g(x) = -5x.
The value of h(g(x)) is calculated by substituting x = -5x in the equation of h(x).
h(g(x)) = 4(-5x) + 6
h(g(x)) = -20x + 6
Hence, the value of the composite functions of h(g(x)) is h(g(x)) = -20x + 6.

The percentage change in the price is 15.78% decrease.
What is the percentage?
A percentage is a figure or ratio that may be stated as a fraction of 100 in mathematics. If we need to compute the percentage of a number, divide it by the entire and multiply by 100. As a result, the percentage denotes a part per hundred. Per 100 is what the term percent signifies. The sign "%" represents it.
Here are some percentage examples:
10% is 1/10 of a fraction.20% is equal to a 1/5 portion.25% is equal to 1/4 fractions.Now,
Initial price=4.1
Final price=3.5
Change=3.5-4.1= -0.6 , minus means decrease in price
final value + initial value=7.6
then
percentage change by midpoint approach = (final value-initial value) / ((final value + initial value)/2) *100
=0.6/3.8*100

X=a+b+4, a is directly Propotional to y² and b is inversely propotional to y, when Y= 2₁ X=18 and y=1, X=-3, Find X when y=4
Answer:
x = 81
Step-by-step explanation:
If a is directly proportional to y²:
[tex]\boxed{a \propto y^2 \implies a=ky^2}[/tex]
If b is inversely proportional to y:
[tex]\boxed{b \propto \dfrac{1}{y} \implies b=\dfrac{m}{y}}[/tex]
Given equation:
[tex]x=a+b+4[/tex]
Substitute the derived expressions for a and b into the given equation:
[tex]\implies x=ky^2+\dfrac{m}{y}+4[/tex]
Substitute the given values of x and y into the equation to create two equations in terms of k and m.
Given that x = -3 when y = 1:
[tex]\implies -3=k+m+4[/tex]
Given that x = 18 when y = 2:
[tex]\implies 18=4k+\dfrac{m}{2}+4[/tex]
Rewrite the first equation to isolate k:
[tex]\implies k=-m-7[/tex]
Substitute the expression for k into the second equation and solve for m:
[tex]\implies 18=4(-m-7)+\dfrac{m}{2}+4[/tex]
[tex]\implies 18=-4m-28+\dfrac{m}{2}+4[/tex]
[tex]\implies -4m+\dfrac{m}{2}=42[/tex]
[tex]\implies -8m+m=84[/tex]
[tex]\implies -7m=84[/tex]
[tex]\implies m=-12[/tex]
Substitute the found value of m into the expression for k and solve for k:
[tex]\implies k=-(-12)-7[/tex]
[tex]\implies k=5[/tex]
Substitute the found values of k and m into the equation to create an equation for x in terms of y:
[tex]\boxed{x=5y^2-\dfrac{12}{y}+4}[/tex]
Finally, to find the value of x when y = 4, substitute y = 4 into the equation and solve for x:
[tex]\implies x=5(4)^2-\dfrac{12}{4}+4[/tex]
[tex]\implies x=5(16)-3+4[/tex]
[tex]\implies x=80-3+4[/tex]

In this problem we find a geometric system formed by a quadrilateral and two diagonals, whose parameters are listed below:
CD = 20 m
m ∠ BCD = 20°
m ∠ ACB = 40°
m ∠ ADC = 45°
m ∠ ADB = 50°
The missing side can be found by combining law of sine and law of cosine:
Law of sine
20 / sin 65° = BD / sin 20°
BD = 7.548
20 / sin 75° = AD / sin 60°
AD = 17.932
