A stadium has 53,000 seats. Seats sell for $25 in Section A, $20 in Section B, and $15 in Section C. The number of seats in Section A
equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,131,000 from each sold-out event. How many seats
does each section hold?
Answers
The number section A, section B and section C seats sold are 26500, 14200 and 12300 respectively.
How to use equation to find the total number of seat in each section?The stadium has 53,000 seats.
Seats sell for $25 in Section A, $20 in Section B, and $15 in Section C.
The number of seats in Section A equals the total number of seats in Sections B and C.
Therefore,
a = b + c
a + b + c = 53000
b + c + b + c = 53000
2b + 2c = 53,000
25a + 20b + 15c = 1131000
25(b + c) + 20b + 15c = 1131000
25b + 25c + 20b + 15c = 1131000
45b + 40c = 1131000
Hence,
2b + 2c = 53000
45b + 40c = 1131000
40b + 40c = 1060000
45b + 40c = 1131000
-5b = - 71000
b = - 71000 / -5
b = 14,200
Therefore,
2(14,200) + 2c = 53000
2c = 53000 - 28400
2c = 24600
c = 24600 / 2
c = 12300
Hence,
a = b + c
a = 14200 + 12300
a = 26500

Select the correct answer. A new building in the shape of a square pyramid is to be constructed. The slant height will be five times the side length of the base. There will be between 20,000 square feet and 50,000 square feet of construction material used for the outside of the building. What would be the maximum possible side length of the base of the building? Round your answer to the nearest foot. Ο Α. 71 feet OB. 89 feet OC. OD. 45 feet 141 feet
Answers
From the information given about the square pyramid, the maximum base length of the building is 67.42 cm.
How do you determine the maximum side length?We are given the following details are:
Base = b
Slant height (l) = 5b
The lateral surface area is calculated using:
L = 2bl
So, we have:
L = 2 * b * 5b
Evaluate the product
L = 10b²
The total surface area is calculated using:
T = L + b²
So, we have:
T = 10b² + b²
Evaluate the sum
T = 11b²
Recall that the maximum surface area is 50,000 square feet
So, we have:
11b² = 50000
Divide both sides by 11
b² = 50000/11
Taking the square root of both sides, we have
b = 67.42
Hence, the maximum base length of the building is 67.42 cm

Answers
Answer:
Step-by-step explanation:
Purchase price (A) : $12,500
Down Payment (B): $3,000
Loan Taken (C = A - B): $9500
D : Interest calculation for $9,500 for 3 years P(1 + rt)
= 9500(1 + (14.5/100) * 3)
= 9500(1 + 0.145 * 3)
= 9500 * 1.435
= $13632.5
E : Interest calculation for $9,500 for 2 years P(1 + rt)
= 9500(1 + (14.5/100) * 2)
= 9500(1 + 0.145 * 2)
= 9500 * 1.29
= $12,255
Difference between D - E
= $13632.5 - $12,255
= $1377.5
Hence the answer is B i.e. $1377.5 less interest for same amount of load for 2 years vs 3 years

Answers
The probability that the diameter of the electric cable that is normally distributed will exceed 0.92 inch is 0.841
What is probability?Probabilities are used to determine the chances, likelihood, possibilities of an event or collection of events
How to determine the probability?The given parameters are:
Mean = 0.9
Standard deviation = 0.2
Calculate the z-score at x = 0.92 using
[tex]z = \frac{x - \mu}{\sigma}[/tex]
This gives
z = (0.92 - 0.9)/0.02
Evaluate the numerator; subtract 0.9 from 0.92
z = 0.02/0.02
Divide 0.02 by 0.02. This gives
z = 1
The probability is then represented as:
P(x > 0.92) = P(z > 1)
Next, we look up the value of the z table of probabilities
From the z table of probabilities, we have:
P(x > 0.92) = 0.841
Hence, the probability that the diameter of the electric cable that is normally distributed will exceed 0.92 inch is 0.841

The exact values of sec θ, tan θ and sin θ are 6.4/4, 5/4 and 5/ 6.4 respectively.
How to determine the trigonometric ratiosFrom the figure, we have the values of the sides to be;
opposite side = 5Adjacent side = 4Let's use Pythagorean theorem to find the hypotenuse(x)
Hypotebuse square = opposite side square + adjacent side square
Substitute the values deduced from the figures given
x² = 5² + 4²
x² = 25 + 16
x² = 41
x = [tex]\sqrt{41}[/tex]
x = 6. 4
sin θ = opposite/hypotenuse
Substitute the values
sin θ = 5/ 6. 4
tan θ = opposite/ adjacent
Substitute the values
tan θ = 5/ 4
sec θ = hypotenuse/ adjacent
substitute the values
sec θ = 6. 4/ 4
Thus, the exact values of sec θ, tan θ and sin θ are 6.4/4, 5/4 and 5/ 6.4 respectively.

Angle L: 70°
The trigonometric ratio used to solve for NM is the tangent ratio.
NM = 57.7 [nearest tenth]
How to Apply the Trigonometric Ratios?Using the triangle sum theorem, find angle L.
Angle L = 180 - 90 - 20 = 70°
Using the tangent ratio, we can use ∠M and LN to solve for NM
Tan 20 = 21/NM [tan ∅ = opposite/adjacent]
NM = 21/tan 20
NM = 57.7 [nearest tenth]
