6.7 = π(r^2)(33.5/12)
r = .874
75/(2 × .874) = 42.9 = 42 barrels
6.7 = (3.14)(r^2)(33.5/12)
r = .874
75/(2 × .874) = 42.9 = 42 barrels

Suppose that 4 friends are given a vintage arcade game that they want to share. If they decide to divide their time, and they decide that they have 26 hours of available time to play in a week, what is each person's fair share of the playing time?
Answers
Answer: 6.5
Step-by-step explanation:
26/4 = 6.5 hours
To calculate this, we simply divide the total available time by the number of people sharing the game:
26 hours / 4 people = 6.5 hours per person
Therefore, each person should get to play the arcade game for 6.5 hours per week if they want to divide their time equally.

Lisa decides that she wants to know the 98% confidence interval for a population mean despite originally setting out to find the 95% confidence interval. How will this affect the width and the margin of error of her confidence interval for a population mean? Assume that the population standard deviation is unknown and the population distribution is approximately normal.
Answers
The breadth and error margin of the confidence interval will rise when the confidence level is raised from 95% to 98%.
We are more certain that the genuine population mean falls inside the interval if the confidence level is larger. The range of feasible values for the population means will be broader since we need to widen the interval in order to reach this higher degree of confidence.
Since the margin of error equals half of the interval's breadth, it is directly proportional to the interval's width. The margin of error will therefore expand as the confidence level does as well.

(b) If the point (8, 5) is on the graph of an odd function, what other point must also be on the graph?
(x, y) =
Answers
The answers are (-8, 5) and (-8, -5)
Given that, the point (8, 5) is on the graph of an even function, we need to find the other point must also be on the graph,
A function f(x) is said to be an even function if it satisfies the following equation: f(−x) = f(x)
A function satisfying this equation has a graph that is symmetric about the y-axis.
So, if the point (8, 5) is on the graph of an even function, the (-8, 5) must also be on the graph of the function.
Also, the point (8, 5) is on the graph of an odd function,
The graph of an odd function is symmetrical about the origin. Therefore, an odd function satisfies the following condition:
-f(x) = f(-x),
Therefore,
(8, 5) = (-8, -5)
Hence, the answers are (-8, 5) and (-8, -5)

a. A train is traveling in a circular track of 53 km radius at 44 km per hour. Find in degrees the angle through which it turns in 1 minute.
Answers
Answer:
0.38 degrees.
Step-by-step explanation:
C = 2π(53) = 106π km
The train is traveling at a speed of 44 km/h, which is equivalent to (44/60) km/min since there are 60 minutes in an hour.
d = (44/60) km/min
θ = (d / C) x 360°
θ = [(44/60) / (106π)] x 360°
θ ≈ 0.38°
Therefore, the angle through which the train turns in 1 minute is approximately 0.38 degrees.
Alan is going to eat a round lollipop that has a radius of 2 inches. What is the lollipop's circumference?
Answers
The circumference of the lollipop is 12.57 inches.
Circumference is the measurement of the distance around the outer edge of a closed curve, particularly a circle. It is the total length of the curve that makes up the boundary of the circle.
The circumference of the circle is given by the formula;
Circumference = 2 × π × radius
where π (pi) is the mathematical constant approximately equal to 3.14159265359...
Given that the radius of the round lollipop is 2 inches, we can substitute this value into the formula;
Circumference = 2 × π × 2
Using the approximate value of π as 3.14159265359..., we can calculate the circumference;
Circumference = 2 × 3.141592 × 2
Circumference ≈ 12.56
Therefore, the circumference of the lollipop is approximately 12.57 inches.

Sarah is building a 10-foot-long pen for her pet rabbits. She wants to make gravel bases for two circular food containers to go inside the pen along with its width, as shown in the diagram. Let y represent the width of the pen and x represent the radii of the gravel bases and food containers. What system of inequalities can be used to determine the width of the pen, y, and the radii of the gravel bases, x?
Answers
1. The width of the pen must be greater than or equal to the sum of the diameters of the two circular food containers, which is equal to 2x + 2x = 4x:
y ≥ 4x2. The width of the pen must also be less than or equal to the length of the pen, which is 10 feet:
y ≤ 103. The radii of the gravel bases must be greater than or equal to the radii of the food containers, which is equal to x:
x ≥ x4. The radii of the gravel bases must also be less than or equal to half the width of the pen, which is equal to y/2:
x ≤ y/2SYSTEM OF INEQUALITIESSystem of inequalities that can be used to determine the width of the pen, y, and the radii of the gravel bases, x, is:
y ≥ 4xy ≤ 10x ≥ 0x ≤ y/2Answer:
Step-by-step explanation:
The sum of the diameters of the gravel bases cannot exceed the width of the pen, so 2x+2x≤y. Rewrite this to get y≥4x as the first inequality in the system.Next, to write the expression for the cost of the fencing, find the perimeter of the rectangle and multiply the perimeter by the cost per foot of fencing. The pen is a rectangle, so the perimeter is 2(10)+2(y), or 20+2y. Multiply the cost ($4.00 per foot) by the perimeter to get 4(20+2y).Now write an expression for the gravel bases for the circular food containers. Because A=πr2 and the cost of the gravel is $2.00 per square foot, multiply the cost of the material by the sum of these areas to get 2(πx2)+2(πx2).The total cost must be less than or equal to $150, so we can say that 4(20+2y)+2(πx2)+2(πx2)≤150. Finally, simplify and solve for y.80+8y+2πx2+2πx2≤15080+8y+4πx2≤1508y≤70−4πx2y≤8.75−0.5πx2So, this is the system.

The total surface area of a
rectangular prism is 1,060 cm². The
prism's base has measurements 8
centimeters and 10 centimeters.
What is the height of the prism?
Answers
Answer:
The surface area of a rectangular prism is given by the formula:
SA = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the prism, respectively. We are given that the surface area of the prism is 1,060 cm², and that the base has measurements 8 cm and 10 cm.
Substituting these values into the formula, we get:
1060 = 2(8)(10) + 2(8)h + 2(10)h
Simplifying and solving for h, we get:
1060 = 160 + 16h + 20h
1060 = 160 + 36h
900 = 36h
h = 25
Therefore, the height of the prism is 25 cm.

How to find the side of a triangle?Patricia is building a garden in her backyard that is shaped like a triangle. She has already built two sides of the garden and they have length of 6 feet and 7 feet.
She wants to find the length of the third side. The angles between the the built sides is 110 degrees.
Therefore, let's find the third sides using the included angle and the two known sides.
using cosine rules,
c² = a² + b² - 2ab cos C
c² = 6² + 7² - 2(6)(7) cos 110
c² = 36 + 49 - 84 cos 110°
c² = 85 - 84(-0.34202014332)
c² = 85 + 28.7296920394
c = √113.729
c = 10.6643799632
c = 10.7 feet
Therefore,
third side of the triangle = 10.7 feet

Answers
The probability that Mia and Lia place in 1st or 2nd is 99/2450. There are two possible scenarios in which Mia and Lia can place in 1st or 2nd: Mia places 1st and Lia places 2nd, or Mia places 2nd and Lia places 1st. The probability of the first scenario is (1/50) * (1/49) = 1/2450. The probability of the second scenario is also (1/50) * (1/49) = 1/2450. Since these two scenarios are mutually exclusive, we can add their probabilities to find the total probability: 1/2450 + 1/2450 = 2/2450. However, we must also account for the fact that there are 49 other people who could place in 3rd. So the final probability is (2/2450) * 49 = 98/2450. Adding the probability that neither Mia nor Lia place in 3rd (1/2450), we get 98/2450 + 1/2450 = 99/2450.

√(6 + 9 +12) = √27 = 3√3
√(-6 + 9 + 12) = √15 = √3√5
√(6 - 9 + 12) = √9 = 3
√(6 + 9 - 12) = √3
(1/4)(3√3)(√3√5)(3)(√3)
= (1/4)(27√3)(√5) = (27√15)/4 = 26.1
Answer:correct answer is 26.1
Step-by-step explanation:
Heron's formula states that the area (A) of a triangle with side lengths a, b, and c is given by:
A = √(s(s-a)(s-b)(s-c))
where s is the semiperimeter, which is half the perimeter of the triangle:
s = (a + b + c) / 2
In this case, the side lengths are a = 6, b = 9, and c = 12. Therefore, the semiperimeter is:
s = (6 + 9 + 12) / 2 = 27 / 2
Using Heron's formula, we can now calculate the area of the triangle:
