Answer:
16 Soccer balls
68 T-shirts
Step-by-step explanation:
Given information:
Total order = 84 itemsCost of a soccer ball = $25Cost of a t-shirt = $9.50Total bill = $1,046Define the variables:
Let x = the number of soccer balls ordered.Let y = the number of t-shirts ordered.Create two equations from the given information:
\(\textsf{Equation 1}: \quad x + y = 84\)
\(\textsf{Equation 2}: \quad 25x+9.5y=1046\)
Rewrite Equation 1 to make y the subject:
\(\implies y=84-x\)
Substitute this into Equation 2 and solve for x:
\(\implies 25x+9.5(84-x)=1046\)
\(\implies 25x+798-9.5x=1046\)
\(\implies 15.5x+798=1046\)
\(\implies 15.5x=248\)
\(\implies x=16\)
Substitute the found value of x into the rewritten form of Equation 1 and solve for y:
\(\implies y=84-16\)
\(\implies y=68\)
Solution

A guy wire for a suspension bridge runs from the ground diagonally to the top of the closest pylon to make a triangle. We can use the Pythagorean Theorem to find the length of guy wire needed. The square of the distance between the wire on the ground and the pylon on the ground is 528,000 feet. The square of the height of the pylon is 19,600 feet. So the length of the guy wire can be found by evaluating sqrt(528,000 + 19,600) . What is the length of the guy wire?
Answer:
740
Step-by-step explanation:
\( {hyp}^{2} = {opp}^{2} + {adj }^{2}\)
Opp=528, 000 feet
Adj = 19,600feet
Hyp=?
\( {x}^{2} = 528000 + 19600\)
\( {x}^{2} = 547600\)
\(x = \sqrt{547600} \)
Therefore,
\(x = 740\)
The data below shows the money Paritosh spends on a weekend. What will be the central angles of each of these categories?with the numbers 40 100 50 50
The central angles for the categories with the numbers 40, 100, 50, and 50 are 60 degrees, 150 degrees, 75 degrees, and 75 degrees, respectively.
To calculate the central angles for each category based on the given numbers 40, 100, 50, and 50, we need to find the proportion of each value to the total sum of all the values. Let's proceed with the following steps:
Step 1: Calculate the total sum of the given numbers: 40 + 100 + 50 + 50 = 240.
Step 2: Find the proportion of each value by dividing it by the total sum and multiplying it by 360 (since a full circle has 360 degrees).
Central angle for the first category: (40/240) * 360 = 60 degrees.
Central angle for the second category: (100/240) * 360 = 150 degrees.
Central angle for the third category: (50/240) * 360 = 75 degrees.
Central angle for the fourth category: (50/240) * 360 = 75 degrees.
The central angles for each category based on the given numbers are 60 degrees, 150 degrees, 75 degrees, and 75 degrees, respectively.
These central angles represent the relative proportions of each category's spending in relation to the total spending. They can be used to create a pie chart or visualize the distribution of expenses in a circular graph.

What is the equation of a hyperbola with a = 7 and c = 9? Assume that the transverse axis is horizontal.
The equation of a hyperbola with a=7 and c=9 is (x-0)²/a²-(y-0)²/b²=1, x²/49-y²/32=1.
Define Hyperbola.A hyperbola is a kind of smooth curve that appears to lie in a plane. It is made up of two connected components or branches that are mirror reflections of one another and look like two infinite bows. A hyperbola is a collection of points whose difference in distance between two foci is a fixed amount. This discrepancy is calculated by subtracting the distance from the farther focus from the distance from the closest focus.
As we know the standard equation of the hyperbola with a horizontal transverse axis is:
(x-h)²/a²-(y-k)²/b²
Now, put the given values a=7 and c=9 in the Pythagorean theorem to get the value of b.
c²=a²+b²
(9)²=(7)²+b²
81=49+b²
81-49=b²
32=b²
Now square root both sides:√
32=√b²
√32=b
Assuming that the center of a hyperbola is (0,0):
(x-0)²/a²-(y-0)²/b²=1
x²/a²-y²/b²=1
x²/(7)²-y²/(√32)²=1
x²/49-y²/32 = 1
Therefore, the equation of a hyperbola with a=7 and c=9 (x-0)²/a²-(y-0)²/b²=1, x²/49-y²/32=1.

The following are the ages (years) of 5 people in a room: 13 , 22 , 15 , 14 , 15 A person enters the room. The mean age of the 6 people is now 16. What is the age of the person who entered the room?
Answer:
17
Step-by-step explanation:
Add up the values (13, 22, 15, 15, 14) and subtract from the product of 16 and 6
Answer:
17
Step-by-step explanation:
the mean is calculated as
mean = \(\frac{sum}{count}\)
let x be the age of the person entering the room, then sum of 6 is
sum = 13 + 22 + 15 + 14 + 15 + x = 79 + x
\(\frac{79+x}{6}\) = 16 ( multiply both sides by 6 to clear the fraction )
79 + x = 96 ( subtract 79 from both sides )
x = 17
the age of the person who entered the room is 17

Fred brought a shirt and a wallet for a total of 34.26 before tax. The price of the wallet was $15 less than the price of the shirt. What was the price of the shirt?
Answer:
The price of the shirt is $24.63.
Step-by-step explanation:
Let's assume the price of the shirt is x. Then the price of the wallet will be x - 15. We know that the total cost before tax is 34.26, so we can set up the equation:
x + (x - 15) = 34.26
Simplifying, we get:
2x - 15 = 34.26
Adding 15 on both sides:
2x = 49.26
Dividing by 2:
x = 24.63
Therefore, the price of the shirt is $24.63.

solve In 2010, the percentage of assisted living residents who had both heart disease and depression was 9%, the percentage with only heart disease was 25%, and the percentage with either condition was 48%. What percentage of assisted living residents had only depression
Answer:
The percentage of assisted living residents had only depression
P(D) =0.32
Step-by-step explanation:
Explanation:-
Given the percentage of assisted living residents who had both heart disease and depression was 9%
Let The event 'H' be the event of heart disease and 'D' be the event of depression
P(H ∩D) = 9% =0.09
The percentage with only heart disease was 25%
P(H) = 0.25
The percentage with either condition was 48%.
P(H∪D) = 48%=0.48
By addition theorem on probability
\(P(H UD) = P(H) +P(D) - P(H n D)\)
\(0.48 = 0.25 + P(D) -0.09\)
P(D) = 0.48 -0.16
P(D) = 0.32
The percentage of assisted living residents had only depression
P(D) =0.32
In the diagram, DG = 12, GF = 4, EH = 9, and HF = 3. Triangle D E F is shown. Line G H is drawn parallel to side D E within the triangle to form triangle G F H. The length of D G is 12, the length of G F is 4, the length of E H is 9, and the length of H F is 3. To prove that △DFE ~ △GFH by the SAS similarity theorem, it can be stated that StartFraction D F Over G F EndFraction = StartFraction E F Over H F EndFraction and ∠DFE is 4 times greater than ∠GFH. ∠FHG is One-fourth the measure of ∠FED. ∠DFE is congruent to ∠GFH. ∠FHG is congruent to ∠EFD.
To prove that △DFE ~ △GFH by SAS similartiy theorem, then option C. ∠DFE is congruent to ∠GFH is appropriate. So that: \(\frac{DF}{GF}\) = \(\frac{EF}{HF}\) and ∠DFE is congruent to ∠GFH.
Given ΔDEF as shown in the diagram attached to this answer, the following can be observed:
By comparing ΔDEF and ΔGFH
DF = DG + GF
= 12 + 4
DF = 16
Also,
EF = EH + HF
= 9 + 3
EF = 12
Comparing the sides of ΔDEF and ΔGFH, we have;
\(\frac{DF}{GF}\) = \(\frac{EF}{HF}\)
\(\frac{16}{4}\) = \(\frac{12}{3}\)
4 = 4
Thus, the two triangles have similar sides.
Comparing the included angle <DFE and <GFH, then;
∠DFE is congruent to ∠GFH
So that the appropriate answer to the given question is option C. ∠DFE is congruent to ∠GFH
Therefore, to prove that △DFE ~ △GFH by the SAS similarity theorem;
\(\frac{DF}{GF}\) = \(\frac{EF}{HF}\) and ∠DFE is congruent to ∠GFH.

Each machine at a certain factory can produce 90 units per hour. The setup cost is 20 dollars for each machine and the operating cost is 26 dollars per hour (total, not 26 dollars per machine per hour). You would like to know how many machines should be used to produce 40000 units, with the goal of minimizing production costs.
First, find a formula for the total cost in terms of the number of machines, n:_______
TC = ______
machines for a total cost of The minimum total cost is achieved when using dollars.
Answer:
a) \(Total Cost=20n+\frac{(\frac{40000}{90}*26)}{n}\)
b) \(n=24\)
Step-by-step explanation:
From the question we are told that:
Rate r=90 units per hour
Setup cost =20
Operating Cost =26
Units=40000
Generally the equation for Total cost is mathematically given by
\(Total Cost=20n+\frac{(\frac{40000}{90}*26)}{n}\)
\(T_n=20n+\frac{11556}{n}\\\\T_n=\frac{20n^2+11556}{n}.....equ 1\)
Differentiating
\(T_n'=\frac{n(40n)-(40n^2+11556)}{n_2}\\\\T_n'=\frac{20n^2-11556}{n^2}.....equ 2\)
Equating equ 1 to zero
\(0=\frac{20n^2+11556}{n}\)
\(n=24\)
Therefore
Substituting n
For Equ 1
\(T_n=\frac{20(24)^2+11556}{24}\)
F(n)>0
For Equ 2
\(T_n'=\frac{20(24)^2-11556}{24^2}\)
F(n)'<0

The equation that represent the given situation is y = 15x + 70
When she plants 3 stalks, each plant yields 115 ounces of beans
The first point = (3, 115)
When she plants 8 stalks, each plant yields 190 ounces of beans
The second point = (8, 190)
The slope of the line m = \(\frac{y_2-y_1}{x_2-x_1}\)
Substitute the values in the equation
The slope of the line m = (190-115) / (8-3)
