There are 8 people who attended the park.
To solve the problem, let's define the variables and write an equation. Let x be the number of people who attended. The total cost is the sum of the parking fee plus the admission fees.
The parking fee is $8.50, and the admission fee per person is $27.50. Therefore, the total cost can be expressed as:
Total Cost = Parking Fee + (Admission Fee per Person * Number of People)
This simplifies to:
$228.50 = $8.50 + $27.50 * x
First, subtract the parking fee from the total cost:
$228.50 - $8.50 = $27.50 * x
$220 = $27.50 * x
Now, divide both sides by the admission fee per person to find x:
x = $220 / $27.50
x = 8
Thus, 8 people attended the park.

Answer:
≈ 1347 mi²
Step-by-step explanation:
The shaded area is the difference between the outer area and the inner area
shaded area = outer - inner
= πr₁² - πr₂²
where r₁ = 14 + 11 = 25 and r₂ = 14, thus
A = π × 25² - π × 14² = 625π - 196π = 429π = 429 × 3.14 ≈ 1347 mi²
Answer:
Step-by-step explanation:
Area of the shaded region = Area of the Outer circle - Area of the inner circle
Outer circle:
r = 14+11 = 25 mi
Area = πr² = π*25²
Inner Circle:
r = 14 mi
Area = πr² = π*14²
Area of shaded region = π*25² - π*14²= π(25² - 14²)
= 3.14*(625 - 196)
=3.14*429
= 1347.06 mi²

Two right triangles, ABD and ACD, were created from ABC by
constructing AD 1 CB.
Follow these steps to prove that sin(B) = sin(C)
1. For
ABD, sin(B) = 1
Answer:
Since their corresponding angles are congruent and the corresponding sides are in proportion
Step-by-step explanation:
For ABD,
Sin (B) = (AD ÷ AB) =1
∴ AD = AB
and if AD = AB
⇒ AD = AC (since AD 1 CB).
From triangle ACD,
Sin(C) = (AD ÷ AC)
Since AD = AC , Hence Sin (B) = Sin (C) = 1
Also From definition of similar triangles ABD and ACD are Similar (i.e their corresponding angles are congruent and the corresponding sides are in proportion)

If JKL ~ MKN, find the value of x.
Answer:
x = 14
Step-by-step explanation:
12(3x - 2) = 32(x + 1) ← distribute both sides
36x - 24 = 32x + 32 ( subtract 32x from both sides )
4x - 24 = 32 ( add 24 to both sides )
4x = 56 ( divide both sides by 4 )
x = 14
The value of x given that JKL ~ MKN is; x= 14.
According to the question;
JKL ~ MKN; In essence, both triangles are congruent.Based on ratios; We can conclude that;
[tex] \frac{12}{x + 1} = \frac{32}{3x - 2} [/tex]
By cross product, we have;
36x - 24 = 32x + 32.4x = 56x = 14.
Ultimately, the value of x given that JKL ~ MKN is; 14.

A marathon is 26.2 miles. What is the least number of times Miguel must run for his total distance run during training to exceed the distance of a marathon?
Missing part of the question
Miguel has started training for a race. The first time he trains, he runs 0.5 mile. Each subsequent time he trains, he runs 0.2 mile farther than he did the previous time.
What is the arithmetic series that represents the total distance Miguel has run after he has trained n times?
Answer:
The least number of times Miguel must run for his total distance run during training to exceed the distance of a marathon is 17.3 miles
Step-by-step explanation:.
Given parameters
Miguel first run = 0.5 mile
Subsequent run = 0.2 mile
This question is an arithmetic progression.
We'll make use of arithmetic progression formula to solve this
Formula:.
Tn = a + (n - 1)d
Where a = first term
n = number of terms
d = common difference
In this case
a = first run = 0.5 mile
d = subsequent run = 0.2 mile
So, Tn = a + (n - 1)d become
Tn = 0.5 + (n - 1) 0.2
Tn = 0.5 + 0.2n - 0.2
Tn = 0.5 - 0.2 + 0.2n
Tn = 0.3 + 0.2n
The arithmetic series of an arithmetic progression is calculated using
Sn = ½(a + Tn) * n
By substituton, we have
Sn = ½(0.5 + 0.3 + 0.2n) * n
Sn = ½(0.8 + 0.2n) * n
Sn = 0.4n + 0.1n²
b.
Since the race is 26.2 miles then the least number of times is given as
Sn ≥ 26
0.4n + 0.1n² ≥ 26.2
0.1n² + 0.4n - 26.2 ≥ 0
Using quadratic formula
n = (-b ± √(b² - 4ac))/2a
Where b = 0.4 a = 0.1 and C = -26.2
So,
n = -0.4 ± √(0.4² - 4 * 0.1 * ,26.2)/2 * 0.1
n = (-0.4 ± √10.64)/0.2
n = (0.4 ± 3.26)/0.2
n = (0.4 + 3.26)/0.2 or (0.4 - 3.26)/0.2
n = 3.46/0.2 or -2.86/0.2
n = 17.3 or -14.3
Since n can't be negative
n = 17.3 miles
The least number of times Miguel must run for his total distance run during training to exceed the distance of a marathon is 17.3 miles

Which of the following is the solution set of the equation shown below? 2x(x+3)-5(x+3)=0
To solve the equation 2x(x+3)-5(x+3)=0, distribute the terms within the parentheses and combine like terms. Then, use the quadratic formula to find the solutions of the quadratic equation.
Explanation:To solve the equation 2x(x+3)-5(x+3)=0, let's distribute the 2x and -5 into the terms inside the parentheses: 2x^2 + 6x - 5x - 15 = 0. Combining like terms, we get 2x^2 + x - 15 = 0. Now we can use the quadratic formula, which states that for an equation of the form ax^2 + bx + c = 0, the solutions are given by:
x = (-b ± √(b^2 - 4ac)) / (2a)
In our case, a = 2, b = 1, and c = -15. Plugging these values into the quadratic formula, we get:
x = (-1 ± √(1^2 - 4(2)(-15))) / (2(2))
x = (-1 ± √(1 + 120)) / 4
x = (-1 ± √121) / 4
x = (-1 ± 11) / 4
So the two solutions are x = 10/4 and x = -12/4, which can be simplified to x = 5/2 and x = -3.

A new shopping mall is gaining in popularity. Every day since it opened, the number of shoppers is 20% more than the number of shoppers the day before. The total number of shoppers over the first 4 days is 671. How many shoppers were at the mall on the first day?
Answer:
The number of buyers on the first day was approximately 324.
Step-by-step explanation:
In this case we have a initial number of shoppers "C" that we want to know and this grows at a steady rate of 20% per day, like a compound interest, we also know the total number of shoppers after 4 days, so we have the final amount of shoppers. We can use the formula for compound interest in order to calculate the number of shoppers in the first day as shown bellow:
M = C*(1 +i)^(t)
Where M is the total amount of shoppers, i is the growth rate and t is the time elapsed.
671 = C*(1 + 0.2)^(4)
671 = C*(1.2)^4
671 = C*2.0736
C = 671/2.0736 = 323.5918
Since there can't be a 0.59 buyer, we will round the number to 324.

a 11 gram sample of substance that's used to treat thyroid disorders s has a k-value of 0.1247
Answer:
You don't have a question but I'll answer what I can.
half-life = natural log (.5) / k
half-life = -.693147 / .1247
half-life = 5.561106656
It seems you did not express the k-value properly.
1) A k-value should have a negative value.
2) A k-value should also have units.
For example, the k-value of tungsten 181 is
-0.005723757 / days
Step-by-step explanation:
Final answer:
a half-life of 5.5 days.
Explanation:
To find the half-life (t1/2) using the decay constant (k), the formula that relates them for the decay of a radioactive substance, typically used for first-order kinetics, is t1/2 = ln(2)/k, where ln(2) is the natural logarithm of 2. Given the decay constant k = 0.125, the half-life is calculated as follows:
t1/2 = ln(2) / 0.125
t1/2 = 5.545 / 0.125
t1/2 = 5.5 days
The mass of the substance does not affect the half-life, so the initial 11-gram sample size is not used in the calculation. Thus, the substance's half-life, rounded to the nearest tenth, is 5.5 days.
This net can be folded to form a cube with a side length of 20 units.
