Answer:
A
Step-by-step explanation:
15 red balls = 15r
50 yellow balls = 50y
Add them together: 15r + 50y
Greater than symbol is >
Since the sum of 15 red and 50 yellow is greater than 400, the resulting equation must be 15r + 50y > 400
(if you're still stuck, consider the greater than symbol as an alligator with the numbers on either side representing a number of fish. The alligator always wants to eat the larger number of fish, so whatever number the mouth is open toward is the larger number)

Bottom letter is F
Answer:
1. \(x \approx 229.8\)
2. \(x \approx 2.6\)
Step-by-step explanation:
1. We can use the following trigonometric ratio since we are given the adjacent side and need to find the hypotenuse from the angle:
\(cos(x) = \frac{adjacent}{hypotenuse}\\cos(72) = \frac{71}{x}\\x = \frac{71}{cos(72)}\\x \approx 229.8\)
2. We can use the following trigonometric ratio since we are given the adjacent side and need to find the opposite from the angle:
\(tan(x) = \frac{opposite}{adjacent}\\tan(43) = \frac{x}{2.8}\\x = tan(43) \times 2.8\\x \approx 2.6\)

What is law of sine?The law of sine is the nothing but the relationship between the sides of the triangle to the angle of the triangle (oblique triangle).
It can be given as,
\(\dfrac{\sin A}{a} =\dfrac{\sin B}{b} =\dfrac{\sin C}{c}\)
Here \(A,B,C\) are the angle of the triangle and \(a,b,c\) are the sides of that triangle.
Given information-
The triangle for the given problem is attached below.
In the triangle the base of the triangle is 2.6 units long.
The sine law for the given triangle can be written as,
\(\dfrac{\sin X}{x} =\dfrac{\sin Y}{y} =\dfrac{\sin Z}{z}\)
As the value of \(y\) side is known and the value of \(z\) has to be find. Thus use
\(\dfrac{\sin Y}{y} =\dfrac{\sin Z}{z}\)
Put the values,
\(\dfrac{\sin 51}{2.6} =\dfrac{\sin 76}{z}\)
Solve it for the \(z\),
\(z=\dfrac{\sin 76\times 2.6}{\sin 51}\\z=3.2462\)
Hence the value of the \(z\) is 3.2 (rounded to the nearest tenth). The option 2 is the correct option.

Find the sum of the interior angles of a polygon that has 9 sides?
Answer: (9 - 2) ⋅ 180 ° = 7 ⋅ 180 ° = 126 0 °
Step-by-step explanation:
A braced cut, 5 m wide and 7.5 m deep is
proposed in a cohesionless soil deposit having
effective cohesion C* = 0 and effective friction
angle ¢' = 36°. The first row of struts is to be
installed at a depth of 0.5 m below ground surface
and spacing between the struts should be 1.5 m.
If the horizontal spacing of struts is 3m and unit
weight of the deposit is 20 kN/m3, the maximum
strut load will be _____
The maximum strut load is 70.87 kN. The maximum strut load can be calculated using the following equation: Maximum strut load = 2 * unit weight * gravity * depth * sin(friction angle) * cos(friction angle)
In this case, the unit weight is 20 kN/m3, the gravity is 9.81 m/s^2, the depth is 7.5 m, and the friction angle is 36°. Plugging these values into the equation, we get the following:
Maximum strut load = 2 * 20 * 9.81 * 7.5 * sin(36°) * cos(36°) = 70.87 kN
Therefore, the maximum strut load is 70.87 kN.
The maximum strut load occurs at the first row of struts, which is installed at a depth of 0.5 m below ground surface. The strut load decreases with depth, and the maximum strut load is reached at the first row of struts.
The strut load is caused by the weight of the soil above the struts. The soil above the struts exerts a lateral force, which is resisted by the struts. The maximum strut load occurs when the lateral force is at its maximum.
The maximum strut load is an important design consideration for braced cuts. The strut load must be able to be safely carried by the struts. If the strut load is too high, the struts may buckle or fail.

The volume of the given combined solids is 675 cm³.
The given combined solid is made up of two solids. A rectangular solid and a triangular prism. The dimensions of the rectangular solid are length, width, and height 15 cm, 6 cm, and 5 cm, respectively, while the triangular prism has a height of 6 cm and a base of 5 cm.
The rectangular solid is placed on the triangular prism such that the rectangular solid's width coincides with the base of the prism's triangle.Find the volume of the given combined solids.
Since the rectangular solid is on top of the triangular prism, we will compute the two volumes separately and then add them together to obtain the combined volume.
Volume of rectangular solid = l × w × h= 15 cm × 6 cm × 5 cm= 450 cm³
Volume of triangular prism= 1/2 × base × height × length= 1/2 × 5 cm × 6 cm × 15 cm= 225 cm³
To get the combined volume, we add the two volumes together:Combined volume= 450 cm³ + 225 cm³= 675

f = 2xy3 i 4x2 y2 j c: the boundary of the "triangular" region in the first quadrant enclosed by the x-axis, the line x = 1, and the curve y = x3
The boundary of the "triangular" region in the first quadrant enclosed by the x-axis, the line x = 1, and the curve y = x^3 is given by the line segment from (0, 0) to (1, 1) and the curve y = x^3 in the interval [0, 1].
To find the boundary of the triangular region, we need to identify the points where the x-axis, the line x = 1, and the curve y = x^3 intersect in the first quadrant.
The x-axis: The x-axis is the line y = 0. Therefore, the point of intersection with the x-axis is (x, y) = (x, 0).
The line x = 1: This is a vertical line passing through x = 1. Therefore, the point of intersection with the line x = 1 is (x, y) = (1, y).
The curve y = x^3: This is a curve in the first quadrant defined by y = x^3. To find the intersection points with this curve, we equate y = x^3 and solve for x. This gives us x = y^(1/3).
Now, let's analyze the boundary of the triangular region in the first quadrant:
a) Starting point: (0, 0) - The boundary begins at the origin (0, 0).
b) Line segment: From (0, 0) to (1, 0) - This segment lies along the x-axis.
c) Curve segment: From (1, 0) to (1, 1) - This segment lies on the curve y = x^3 and corresponds to x = 1.
d) Final point: (1, 1) - The boundary ends at the point (1, 1).
In conclusion, the boundary of the "triangular" region in the first quadrant enclosed by the x-axis, the line x = 1, and the curve y = x^3 consists of the line segment from (0, 0) to (1, 0) along the x-axis, and the curve segment from (1, 0) to (1, 1) on the curve y = x^3.

The difference of two numbers is 4. Their sum is 22. Find the numbers
Answer:
let the two numbers = x and y
according to the statement : x-y=4
x+y=22
by elimination method: 2x=26
x=13
so... y = 13-4=9
Answer:
The two numbers (x and y) are 13 and 9 respectively. 13 minus 9 is 4 and 13 plus 9 is 22.
Step-by-step explanation:
Let the two numbers be x and y.
The difference between x and y (x - y) = 4. (eqn 1)
Their sum (x + y) = 22. (eqn 2)
From eqn 1, we can get that x = 4 + y
Substituting x as (4 + y) in eqn 2 gives the following:
(4+y) + y = 22
4 + 2y = 22
and 2y = 22 - 4
2y = 18
dividing both sides by 2 gives y = 9.
Substituting y as 9 in eqn 1 gives
x - 9 = 4
x = 4 + 9
x = 13

Answer:
y = \(\frac{1}{2}\) x - 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (6, 1 ) and (x₂, y₂ ) = (- 6, - 5 )
m = \(\frac{-5-1}{-6-6}\) = \(\frac{-6}{-12}\) = \(\frac{1}{2}\) , then
y = \(\frac{1}{2}\) x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation

The test score is 91.5.
z-score:
A z-score is the number of standard deviations from the mean value of the reference population.
Here we have to find the test score.
Mean(μ) = 90
Standard deviation(б) = 15
z-score = 0.1
Formula for z-score:
z = X - μ / б

The concept of perceptual selectivity leads listeners to mold messages to fit their own conceptual frameworks. In other words, individuals often tend to hear only what they want to hear and ignore the rest. They're more likely to accept messages that are consistent with their current beliefs or values while rejecting messages that conflict with them.
Therefore, in order to communicate effectively, it's essential to understand the recipient's perceptual filter and tailor the message accordingly. Decision making in complex business situations is rarely clear-cut and often involves choosing from a range of options that are not necessarily obvious. Therefore, decision makers must use their knowledge, experience, intuition, and judgment to analyze the situation and select the best possible solution.
Decision making is also influenced by external factors such as time pressure, availability of resources, and the organization's culture. Memos are a common form of written communication in the business world. They're usually brief, informative, and intended to convey important information to employees or colleagues. Memos are used to communicate a wide range of information, such as policy changes, meeting announcements, project updates, and so on. They're also used to provide feedback, ask questions, or request information from others. Since memos are an internal communication tool, they're generally written in a more informal tone than other types of business communication such as letters or reports.

For a field trip 27 students rode in cars and the rest filled three buses. How many students were in each bus if 147 students were on the trip?
Answer:
40 students per bus
Step-by-step explanation:
147 (Og #)-27(Number riding cars, irrelevant)=120
120/3 (# of buses)= 40 students per bus
Answer:
40 students
Step-by-step explanation:
First, let’s find how many students rode the buses.
There was a total of 147 students on the trip, and 27 rode in cars. The rest rode in buses.
The difference between 147 and 27 will be how many took buses.
Subtract 27 from 147
147-27=120
120 students rode the buses. There were 3 buses, and the students were evenly divided between each bus. Divide 120 by 3.
120/3=40
Therefore, 40 students were on each bus.
A triangle has two sides of length 1 and 4. What is the largest possible whole-number length
for the third side?
Using the triangle inequality theorem, the largest possible whole-number length for the third side is 4.
How to Apply the Triangle Inequality Theorem to Find the Length of the Third Side of a Triangle?The third side of a triangle must be shorter than the sum of the other two sides and longer than the difference between the other two sides.
So, for a triangle with sides of length 1, 4, and x (where x is the length of the third side), we have:
1 + 4 > x
4 + x > 1
1 + x > 4
Simplifying these inequalities, we get:
5 > x
x > 3
x > -3 (this inequality is always true)
The largest possible whole-number length for the third side is 4, since it is the largest integer that satisfies the above inequalities.
