Final answer:
The system of inequalities representing this situation is:
1500X + 1800Y ≤ 150,000.
X + Y ≤ 150.
X ≥ 0 and Y ≥ 0.
Explanation:
Let's define X as the number of air carrier loads and Y as the number of land carrier loads. Given that the mail distribution center processes up to 150,000 pieces of mail each day and the loading equipment can handle a maximum of 150 loads per day, we can write the following system of inequalities:
The total mail processed by both air and land carriers cannot exceed 150,000 pieces:
1500X + 1800Y ≤ 150,000.
The total number of loads carried by both air and land carriers cannot exceed 150 loads:
X + Y ≤ 150.
Furthermore, since there cannot be a negative number of loads, both X and Y have to be non-negative:
X ≥ 0 and Y ≥ 0.
These inequalities model the constraints for the mail distribution center's operations.

Drag the expression that is the most reasonable measurement for each object.
Answer:
A. Length of a Tour Bus ↔ #2. 1.1 × 10¹ meters
B. Width of an apple ↔ #3. 4 × 10⁰ centimeters
C. Distance from Earth to a Satellite ↔ #6. 8 × 10² kilometers
D. Thickness of a human hair ↔ #5. 9 × 10¹ micrometers
Step-by-step explanation:
The length of a tour bus should be measured in meters. It sure is way less than 1 kilometer and way more than a few centimeters. It could be about some meters, more than 5 meters, may be between 10 meters and 15 meters.
The measurement in the box # 2. is 1.1 × 10¹ meters, which is equivalent to 1.1 × 10 meters = 11 meters. Thus, this is a reasonable length.
B. Width of an apple.
The most appropriate unit to measure the width of an apple should be centimeter. It certainly is shorter than 1 meter and bigger than 1 mm.
The width of an apple could be, more or less, around 8 centimeters. The only measurement in the boxes that is in that order is that in the box #3., 4 × 10⁰ centimeters, because 10⁰ = 1, so 4 × 10⁰ = 4 × 1 = 4 centimeters.
C. Distance from Earth to a Satellite
The distance from Earth to a satellite should be measured in kilometers.
You can find in the internet that the distances of the satellites are between 700 kilometers and 36,000 kilometers.
The number in the box #1 is too big, in the order of ten trillions of kilometers, because one trillion is 10¹²; thus that is nonseasonal (too big).
The number in the box #6 is 8 × 10² kilometers, which is equal to 8 × 100 = 800 kilometers.
Thus, 8 × 10² kilometers (box #6) is the most reasonable measurement for the distance from Earth to a Satellite
D. Thickness of a human hair
Of course, kilometers, meters, centimeters and even millimeters are units too big to measure the thickness of a human hair.
One micrometer is 10⁻⁶ meters or 10⁻³ millimeters.
In the internet you can find that diameter of the human hair is in the range from 17 micrometers to 181 micrometers.
The measurement in the box #5. is 9 × 10¹ micrometers, which is equivalent to 9 × 10 = 90 micrometers.
Thus, 9 × 10¹ micrometers is the most reasonable measurement for the thickness of a human hair.
A. Length of a Tour Bus ↔ 2. 1.1 × 10¹ meters
B. Width of an apple ↔ 3. 4 × 10⁰ centimeters
C. Distance from Earth to a Satellite ↔ 6. 8 × 10² kilometers
D. Thickness of a human hair ↔ 5. 9 × 10¹ micrometers
What is Satellite?
A satellite is a moon, planet or machine that orbits a planet or star. For example, Earth is a satellite because it orbits the sun. Likewise, the moon is a satellite because it orbits Earth.

A certain triangle has two 45 angles. What type of triangle is it?
A. Acute scalene
B. Right scalene
c. Right isosceles
D. Acute isosceles
Answer:
C. Right isosceles
Step-by-step explanation:
In Acute scalene triangle, all angles are acute ( less than 90 degrees ) and different,
In Right scalene triangle, two angles are acute and different, while, the third angle is of 90°.
In Right isosceles triangle, two angles are acute and equal, while, the third angle is of 90°.
In Acute isosceles, all angles are acute in which any two angles are equal.
Now, given,
The two angle of the triangles are 45° and 45°,
Let x be the third angle,
⇒ x + 45° + 45° = 180°
⇒ x + 90° = 180°
⇒ x = 90°
Hence, the angles of given triangle are 45°, 45° and 90°,
By the above definitions,
It is clear that, given triangle is right isosceles.

The depreciating value of a semi-truck can be modeled by y = Ao(0.87)x, where y is the remaining value of the semi, x is the time in years, and it depreciates at 13% per year. What is the value of the truck initially, Ao, and how would the graph change if the initial value was only $67,000?
Answer: 1) The value of truck initially would be $87000.
2) at t = 0 , y-axis would be cut at $67000.
Step-by-step explanation:
Since we have given that
[tex]y=A_0(0.87)^x[/tex]
Here, A₀ is the initial value.
Rate of depreciation = 13%
Number of years = x
So, The value of truck initially would be $87000.
As shown in the given figure.
If the the initial value of truck = $67000
Rate will be same but the y-intercept will change.
As change in initial value does not affect the rate but the y - intercept.
Then at t = 0 , y-axis would be cut at $67000.

The volume of a sphere with radius r is 4 3 πr 3 . what is the volume of a sphere with radius 5
Final answer:
To find the volume of a sphere with a radius of 5, plug the value into the formula V = (4/3)πr³. The result is approximately 523.6 cm³.
Explanation:
The question asks for the volume of a sphere with a given radius. The formula to calculate the volume of a sphere is V = (4/3)πr³, where V is the volume and r is the radius of the sphere.
To find the volume of a sphere with radius 5, we substitute r with 5 in the formula:
V = (4/3)π(5)³
V = (4/3)π(125)
V = (4/3)π(125) = 500/3π cm³
The volume of a sphere with radius 5 is therefore 500/3π cubic centimeters, which is approximately 523.6 cm³ when rounded to one decimal place.
Rewrite the equation 8x+6x^2-7=x^2
in standard form and identify a, b, and c.
To rewrite the equation 8x + 6x^2 - 7 = x^2 in standard form, subtract x^2 from both sides and combine like terms. The standard form of the equation is 5x^2 + 8x - 7 = 0. The values of a, b, and c are 5, 8, and -7 respectively.
Explanation:The given equation is 8x + 6x^2 - 7 = x^2.
To rewrite it in standard form, we need to collect like terms. Subtracting x^2 from both sides, we get: 6x^2 + 8x - x^2 - 7 = 0.
Combining like terms, the standard form of the equation is 5x^2 + 8x - 7 = 0.
Here, a = 5, b = 8, and c = -7.

A carpenter is building a rectangular bookcase with diagonal braces across the back, as shown. The carpenter knows that angle ADC is a right angle and that angle BDC is 32° greater than mangle ADB. Solve an equation to find angle BDC and angle ADB.
Answer:
m∠ADB = 29° and m∠BDC = 61°
Step-by-step explanation:
It is given that m∠ADC = 90°
Since m∠ADB + m∠BDC = 90° [∠ADB and ∠BDC are complimentary]
Since ∠BDC = ∠ADB + 32°
So, m∠ADB + m∠ADB + 32° = 90°
2(m∠ADB) + 32° = 90°
2(m∠ADB) = 90 - 32
2(m∠ADB) = 58°
m∠ADB = 29°
Since m∠ADB + m∠BDC = 90°
So, m∠BDC + 29° = 90°
m∠BDC = 90 - 29
= 61°
Therefore, m∠ADB = 29° and m∠BDC = 61°
m∠ADB = 29° and m∠BDC = 61°
Solving this will just be based on some basic angle theorems in a triangle.
We are given; m∠ADB = 29° and m∠BDC = 61° We are told that m∠ADC is a right angle. This means that; m∠ADC = 90°Now, since m∠ADC = 90°, it means that;m∠ADB + m∠BDC = 90° (because m∠ADB and m∠BDC are complimentary angles due to the fact that angle at point D is 90°)
We are also told that;m∠BDC is 32° greater than angle m∠ADB
This means that we can write as;
m∠BDC = m∠ADB + 32°
From earlier, we saw that;m∠ADB + m∠BDC = 90°
Thus, putting m∠ADB + 32° for m∠BDC, we will have;m∠ADB + m∠ADB + 32° = 90°
2(m∠ADB) + 32° = 90°
Subtract 32° from both sides to get;
2(m∠ADB) = 90° - 32°
2(m∠ADB) = 58°
m∠ADB = 58°/2
m∠ADB = 29°
Puttting 29° for m∠ADB into; m∠ADB + m∠BDC = 90° gives us;29° + m∠BDC= 90°
Subtract 29° from both sides to get;
m∠BDC = 90° - 29°
m∠BDC = 61°
In conclusion, m∠ADB = 29° and m∠BDC = 61°Read more at; brainly.com/question/4687866

Answer: D Opposite sides of a parallelogram are congruent.
Step-by-step explanation:
The correct answer is the Opposite sides of a parallelogram are congruent.
What is a parallelogram?A parallelogram is a quadrilateral having four sides and the two opposite sides are equal and parallel to each other.
Consider a parallelogram with diagonals that are congruent and perpendicular.
In triangles Δ AOB and Δ AOD,
OA = OA (common)
OB = OD (Since the diagonals of a parallelogram bisect each other)
∠ AOB = ∠ AOD = 90° (diagonals are perpendicular)
Therefore, Δ AOB ≅ Δ AOD (By SAS postulate)
Since, corresponding parts of congruent triangles are equal,
AB = AD
