Answer:
30) x=124
31) x=72
Step-by-step explanation:
30 Explanation: The shape has a total of 720 degrees since it is a hexagon. There are two right angles you can subtract 180 from the 720 which leaves you with 540. You know with the rest of the information can combine the remaining angles and make the equation 4x+44=540. You then get x=124.
31 Explanation: here is a total of 540 degrees in the shape. Since the angles are all congruent you 540/5=108. Since you need x you need to do x+108=180. This means x=72.

use the scatter plot and the trend line to show answer a-c. Write an equation for the trend line. predict the value of y when x =21 Predict the value of x when y = 150
Answers
Answer:
See Explanation
Step-by-step explanation:
This question is incomplete, as the required scatter plot is not included in the question. I will answer your question with the attached plot.
Solving (a): The equation
Pick any \(two\) \(points\)on the \(trend\) line
\((x_1,y_1) = (30,40)\)
\((x_2,y_2) = (80,70)\)
\(y = 0.6x + 22\)
Calculate the slope (m)
\(m = \frac{y_2 - y_1}{x_2 -x_1}\)
\(m = \frac{70 - 40}{80-30}\)
\(m = \frac{30}{50}\)
\(m = 0.6\)
The equation is then calculated as:
\(y = m(x - x_1) + y_1\)
This gives:
\(y = 0.6(x - 30) + 40\)
\(y = 0.6x - 18 + 40\)
\(y = 0.6x + 22\)
Solving (b): y, when \(x = 21\)
\(y = 0.6x + 22\)
Substitute \(x = 21\)
\(y = 0.6 * 21 + 22\)
\(y = 12.6 + 22\)
\(y = 34.6\)
Solving (c): x when \(y=150\)
\(y = 0.6x + 22\)
Substitute \(y=150\)
\(150 = 0.6x + 22\)
Collect like terms
\(0.6x = 150 -22\)
\(0.6x = 128\)
Solve for x
\(x = \frac{128}{0.6}\)
\(x = 213.3\)

What is the value -134+53
Answers
Answer:
To find -134 + 53, add the ones place (4+3=7) and the tens place (5+3=8), giving you -81.
Answer: -81.
Answer:
-81
Step-by-step explanation:
You subtract the absolute values and take the sign of the larger absolute value.
Absolute value is the distance from zero. This will be a positive number
134 - 53 = 81
The sign will be negative because the sign of the higher absolute value number is negative. 134 has a larger absolute value than 53 and it is negative, so our answer is negative.

What is the minimum value of the function over the interval -5 < x < 5? h(x) = log[(x – 5)2 + 3]
Answers
The minimum value of the function h(x) = log[(x - 5)² + 3] over the interval -5 < x < 5 is approximately log[3.000001].
The minimum value of the function h(x) = log[(x - 5)² + 3] over the interval -5 < x < 5 can be found through the following.
Recognize that the logarithm function is increasing.
Minimize the argument of the logarithm, i.e., (x - 5)² + 3.
Observe that (x - 5)² is always non-negative since it is a square of a real number.
The minimum value of (x - 5)² occurs when x = 5 (in this case, (x - 5)² = 0).
However, x cannot be equal to 5 because the interval is -5 < x < 5.
Since the interval is open, find the minimum value for (x - 5)² in this interval, which occurs when x is as close to 5 as possible within the given interval. This would be x = 4.999.
Substitute this value of x into the function:
h(x) = log[(4.999 - 5)² + 3] = log[0.001² + 3] ≈ log[3.000001].
Hence, the minimum value of the function h(x) = log[(x - 5)² + 3] over the interval -5 < x < 5 is approximately log[3.000001].

if n(0) = 30 and λ = 1.20, what is the population size for year one?
Answers
Therefore, the population size for year one is approximately 75.199.
Assuming that this is a question about exponential growth, we can use the formula:
n(t) = n(0) * e^(λt)
where n(0) is the initial population size, λ is the growth rate, t is the time in years, and e is the base of the natural logarithm.
For year one, t = 1, so we have:
n(1) = 30 * e^(1.20*1) = 30 * e^1.20

Answers
The maximum value of P is ______________ at the point (x, y) = (______________).
What is the maximum value of P and its corresponding point (x, y)?
To solve the linear programming problem using the method of corners, we need to examine the feasible region defined by the given constraints and identify the corner points. The objective is to maximize the objective function P = 5x - 6y.
The given constraints are:
1. x + 3y ≤ 15
2. 5x + y ≤ 19
3. x ≥ 0
4. y ≥ 0
We plot the feasible region by graphing the boundary lines defined by each constraint and shading the region that satisfies all the constraints.
Next, we evaluate the objective function at each corner point of the feasible region. The corner points are the vertices of the shaded region.
By substituting the coordinates of each corner point into the objective function P = 5x - 6y, we calculate the corresponding P-values.
The maximum value of P is the highest P-value obtained among all the corner points. Its corresponding point (x, y) represents the coordinates at which the maximum value occurs.
To provide the specific values for the maximum value of P and its corresponding point (x, y), the calculations need to be performed based on the corner points of the feasible region.

Answers
Answer: 40 Percent
Step-by-step explanation:
105.6 Inches / 12 inches per feet = 8.8 Feet
8.8/22 annual = .4
.4 x 100 = 40 Percent
The percentage of its average annual snowfall has fallen in Redfield so far is 40 percent.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, Redfield receives an annual average snowfall of 22 feet.
We know that, 1 foot = 12 inches
Now, 22 feet = 22×12
= 264
This year Redfield has received 105.6 inches of snow.
Here, percentage = 105.6/264 ×100
= 0.4×100
= 40%

An inflatable ball can be modeled as a hollow sphere. Miguel
measures the outer diameter of the ball to be 50 cm. If the
material that makes up the ball has a thickness of 1.25 cm, find
the total volume of material that makes up the ball. Round your
answer to the nearest hundredth if necessary. (Note: diagram is
not drawn to scale.)
Answers
we can find the total volume of material that makes up the ball by subtracting the volume of the hollow space from the volume of the sphere:
V = 20,834 cm^3 - 19,848.44 cm^3
= 985.56 cm^3
what is volume?Volume is a measure of the amount of space occupied by an object or a substance. It is typically measured in units such as cubic meters (m^3), cubic centimeters (cm^3), or cubic feet (ft^3).
What is diameter?Diameter is a measure of the distance across the widest part of a circular object, such as a circle or a sphere. It is equal to twice the radius of the object and is typically measured in units such as millimeters (mm), centimeters (cm), or inches (in). It is a linear measurement.
To find the total volume of material that makes up the ball, we need to find the volume of the sphere and then subtract the volume of the hollow space in the center.
We can begin by calculating the volume of the sphere using the formula for the volume of a sphere:
V = (4/3) * pi * r^3
Where V is the volume, pi is approximately 3.14, and r is the radius of the sphere.
The outer diameter of the ball is 50 cm, so the radius of the sphere is (50/2) = 25 cm.
Substituting these values into the formula, we get:
V = (4/3) * 3.14 * (25 cm)^3
= (4/3) * 3.14 * 15,625 cm^3
= 20,834 cm^3
Next, we need to find the volume of the hollow space in the center of the ball, which is the same as the volume of a smaller sphere with a radius of (25 cm - 1.25 cm) = 23.75 cm.
So the volume of the hollow space is :
V = (4/3) * pi * (23.75 cm)^3
= (4/3) * 3.14 * (23.75 cm)^3
= 19,848.44 cm^3
Finally, we can find the total volume of material that makes up the ball by subtracting the volume of the hollow space from the volume of the sphere:
V = 20,834 cm^3 - 19,848.44 cm^3
= 985.56 cm^3

calculate the molecular weight of a gas with a density of 1.524 g/l at stp.
Answers
To calculate the molecular weight of a gas with a density of 1.524 g/l at STP, we can use the ideal gas law: PV = nRT. At STP, the pressure (P) is 1 atm, the volume (V) is 22.4 L/mol, and the temperature (T) is 273 K. The molecular weight of the gas with a density of 1.524 g/L at STP is approximately 32.0 g/mol.
Rearranging the equation, we get n = PV/RT.
Next, we can calculate the number of moles (n) of the gas using the given density of 1.524 g/l. We know that 1 mole of any gas at STP occupies 22.4 L, so the density can be converted to mass by multiplying by the molar mass (M) and dividing by the volume: density = (M*n)/V. Rearranging the equation, we get M = (density * V) / n.
Substituting the given values, we get n = (1 atm * 22.4 L/mol) / (0.0821 L*atm/mol*K * 273 K) = 1 mol. Then, M = (1.524 g/L * 22.4 L/mol) / 1 mol = 34.10 g/mol. Therefore, the molecular weight of the gas is 34.10 g/mol.
To calculate the molecular weight of a gas with a density of 1.524 g/L at STP, you can follow these steps:
1. Recall the ideal gas equation: PV = nRT
2. At STP (Standard Temperature and Pressure), the temperature (T) is 273.15 K and the pressure (P) is 1 atm (101.325 kPa).
3. Convert the density (given as 1.524 g/L) to mass per volume (m/V) by dividing it by the molar volume at STP (22.4 L/mol). This will give you the number of moles (n) per volume (V):
n/V = (1.524 g/L) / (22.4 L/mol)
4. Calculate the molar mass (M) of the gas using the rearranged ideal gas equation, where R is the gas constant (8.314 J/mol K):
M = (n/V) * (RT/P)
5. Substitute the values and solve for M:
M = (1.524 g/L / 22.4 L/mol) * ((8.314 J/mol K * 273.15 K) / 101325 Pa)
6. Calculate the molecular weight of the gas:
M ≈ 32.0 g/mol
Therefore, the molecular weight of the gas with a density of 1.524 g/L at STP is approximately 32.0 g/mol.
