Answers
Answer: The triangle is obtuse!
Step-by-step explanation:
The triangle is obtuse, because 86^2 is greater than the sum of the squares of the other two sides (44^2 + 73^2). This can be seen by using the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the two sides is equal to the square of the hypotenuse. Since the sum of the squares of the two sides is less than the square of the hypotenuse, we can conclude that this triangle is obtuse.

Mary Lou Mason purchased baby bottles for $4.56, baby formula for $12.45, and a pacifier for $2.13. For all purchases she must pay the state sales tax of 6.5 percent and the county tax of 1.5 percent. What is the tax on her purchases? Show all of your work.
Answers
Mary Lou Mason's total taxes on her purchase would be $1.37.
What are taxes?Taxes are mandatory payments to the government that are used to fund public services such as infrastructure, education, and health care. Taxes can be direct, such as income taxes, or indirect, such as sales taxes.
Mary Lou Mason's total purchase was $19.14.
To calculate the total taxes for her purchase, we can use the following formula:
Tax = (State Sales Tax %) x (Total Purchase) + (County Tax %) x (Total Purchase)
Therefore, the total taxes for Mary Lou Mason's purchase would be:
Tax = (6.5%) x ($19.14) + (1.5%) x ($19.14)
Tax = (0.065 x 19.14) + (0.015 x 19.14)
Tax = 1.24 + 0.13
Tax = $1.37
Mary Lou Mason's total taxes on her purchase would be $1.37.

Answer:
Step-by-step explanation:
considering A). hemisphere diameter = 48 yd
volume of hemisphere = (2/3)*pi*(r)^3
the radius of hemisphere = diameter/2 = 48/2 = 24 yd
hence, the volume of hemisphere = (2/3)*pi*(24)^3 yd^3
taking pi = 3.14
volume = 28938.24 yd^3 approximately volume = 28940 yd^3
considering B). Circumference of a great circle = 26 m
circumference of sphere = 2*pi*r
therefore r = 4.14 m
volume of sphere = (4/3)*pi*(r)^3
volume of sphere = 297.077 m^3
Answer:
24. A. 28952.9 yd²
B. 297.2 m³
Step-by-step explanation:
24.
A.
diameter=48 yd
radius (r)=diameter/2=48/2=24yd
We have
Volume of Hemisphere= ⅔*πr³=⅔*π*r³
Substituting value
Volume of Hemisphere=⅔*π*24³=28952.9 yd³
B.
Circumference of great circle=2πr=26m
2πr=26
r=26/(2π)
r=4.14
Now
Volume of sphere = 4/3*πr³
Volume of sphere=4/3*π*4.14³=297.2 m³

The cake is shaped as a cylinder of radius 9 inches and height of 4 inches
The rule of the volume of the cylinder is
\(V=\pi r^2h\)r is the radius
h is the height
Since the diameter is 9, then
r = 9/2 = 4.5
Since the height is 4
h = 4
Substitute them in the rule
\(\begin{gathered} V=\pi(4.5^2)(4) \\ \\ V=\pi(20.25)(4) \\ \\ V=254.469\text{ in}^3 \end{gathered}\)The volume of the cake is 254.469 cubic inches
A) The answer is 254.469 in.^3
Since the length of the arc is 3 inches, then the volume of each part is
\(\begin{gathered} V=\frac{3}{\pi(9)}\times254.469 \\ \\ V=26.99999 \\ \\ V\approx27\text{ in}^3 \end{gathered}\)B) The answer is 27 in^3 the 2nd choice
C)
We will divide the volume of one piece by the volume of the cake to find the probability of one piece

The maximum revenue possible in this situation is 15625/A dollars, where A is the coefficient in the quadratic equation.
To find the maximum revenue possible in this situation, we can use the concept of vertex or the vertex form of a quadratic equation.
The revenue equation is given by R = -Ax^2 + 250x, where A is a constant coefficient.
The maximum revenue occurs at the vertex of the parabolic curve represented by the equation. The x-coordinate of the vertex can be found using the formula x = -b / (2a), where a and b are the coefficients of the quadratic equation.
In this case, a = -A and b = 250. Plugging in these values, we get:
x = -250 / (2 * (-A))
= 125 / A
To find the maximum revenue, we substitute this value of x into the revenue equation:
R = -A * (125 / A)^2 + 250 * (125 / A)
= -A * (15625 / A^2) + (31250 / A)
= -15625 / A + 31250 / A
= 15625 / A
The maximum revenue is given by 15625 / A. The value of A is not specified in the question, so we cannot determine the exact maximum revenue without knowing the value of A. However, we can say that the maximum revenue increases as A decreases.

You want to know about the dining habits of college students in the US. Since you do not have resources to survey all college students in the nation, you take a random sample of 1501. You learn that, on average, they eat out 4 times per week. Also, these sample data are generally distributed about the average of 4 times, by 1.5 times per week. 1. What is the average times per week that college students across the nation eat out
Answers
Answer:
the average times per week that college students across the nation eat out lies within these 95% confidence interval
\( 3.938 < \mu < 4.062 \)
Step-by-step explanation:
From the question we are told that
The sample size is n = 1501
The sample mean is \(\= x = 4\)
The standard deviation is \(\sigma = 1.5\)
From the question we are told the confidence level is 95% , hence the level of significance is
\(\alpha = (100 - 95 ) \%\)
=> \(\alpha = 0.05\)
Generally from the normal distribution table the critical value of \(\frac{\alpha }{2}\) is
\(Z_{\frac{\alpha }{2} } = 1.96\)
Generally the margin of error is mathematically represented as
\(E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }\)
=> \(E = 1.96 * \frac{1.5 }{\sqrt{1501} }\)
=> \(E = 0.06196 \)
Generally the estimate for average times per week that college students across the nation eat out at a 95% confidence is mathematically represented as
\(\= x -E < \mu < \=x +E\)
\(4 -0.06196 < \mu < 4 + 0.06196\)
=> \( 3.938 < \mu < 4.062 \)
Hence the true average times per week that college students across the nation eat out lies within this interval

What is the solution to the system of equations?
7z+3y=-11
2z+ 5y = 1
Answers
Answer:
y=1 , z=-2
Step-by-step explanation:
I will use the method of elimination :
Multiply the top equation by 5 to make equation 3 :
35z + 15y = -55
Multiply bottom equation by 3 to make equation 4:
6z + 15y = 3
Subtract equation 3 from equation 4 to eliminate the y :
-29z = 58
Divide both sides by -29 to solve for z :
z = 58 ÷ -29
z = -2
Substitute this value into either equation 1 or 2 to solve for y :
I chose equation 2 :
2(-2) + 5y = 1
-4 + 5y = 1
Add 4 to both sides :
5y = 5
Divide both sides by 5 :
y = 1

HELP PLEASEE!! The aquarium has 6 fewer yellow fish than green fish. 40% of the fish are yellow. How many green fish are in the aquarium? Show your work. Show all steps please.
Answers
Green fish: x
Yellow fish: x - 6
So, the total number of fish = x + (x - 6) = 2x - 6
40% of the fish are yellow, so:
0.4 (2x - 6) = x - 6
0.8x - 2.4 = x - 6
- 0.2x = - 3.6
x = 18
Thus, green fish = 18
The graph shows the relationship between time and the number of soda bottles a machine can make. Use the points (5,100) and (7,140) to find the number of soda bottles the machine can make each minute.
Answers
Based on the graph which shows the relationship between time and the number of soda bottles a machine can make, this machine can make 20 soda bottles each minute.
How to calculate the number of soda bottles?In Geometry, the rate of change of any straight line simply refers to the slope and it can be calculated by using this mathematical equation (expression);
Rate of change (slope), m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Rate of change (slope), m = (y₂ - y₁)/(x₂ - x₁)
From the information provided in the graph above, we can logically deduce the following data points located on the line:
Points on the x-coordinate = (5, 7).Points on the y-coordinate = (100, 140).Substituting the given data points into the rate of change formula, we have the following;
Rate of change (slope), m = (y₂ - y₁)/(x₂ - x₁)
Rate of change (slope), m = (140 - 100)/(7 - 5)
Rate of change (slope), m = 40/2
Rate of change (slope), m = 20.

The experimental probability that the next train to pull into Lakeside Station will be full is 7/10.
The experimental probability of the next train to pull into Lakeside Station being full can be calculated by dividing the number of times a full train occurred by the total number of trains observed.
Given that out of the last 20 trains, 14 were full, we can express the experimental probability as a fraction:
P(full) = Number of full trains / Total number of trains observed
P(full) = 14 / 20
