https://brainly.com/question/20489969

The correct answer is the circle's circumference is approximately 25.12 millimeters.

To find the circumference of a circle, one can use the formula:

[tex]\[ C = 2\pi r \][/tex]

where [tex]$ C $[/tex] is the circumference, [tex]$ \pi $ (pi)[/tex] is a mathematical constant approximately equal to 3.14, and [tex]$ r $[/tex] is the radius of the circle.

Given that the radius [tex]$ r $[/tex] is 4 millimeters, we can substitute the values into the formula:

[tex]\[ C = 2 \times 3.14 \times 4 \text{ mm} \][/tex]

Now, we perform the multiplication:

[tex]\[ C = 2 \times 3.14 \times 4 = 25.12 \][/tex]

A trucker traveled an average of 48.6 miles each hour on a 583.2-mile trip. For how many hours did the trucker travel?

Answers

Divide 583.2 by 48.6 to get your answer, 12 hours.

Answer: The trucker traveled for 12 hours.

Step-by-step explanation:

Given : A trucker traveled an average of 48.6 miles each hour on a 583.2-mile trip.

i.e. Total distance = 583.2 miles

Average speed = 48.6 miles per hour

Using Formula , [tex]\text{Total Time}=\dfrac{\text{Total Distance}}{\text{Average speed}}[/tex]

We have

[tex]\text{Total Time}=\dfrac{583.2}{48.6}\\\\=\dfrac{5832}{486}\\\\=12\text{ hours}[/tex]

Hence, the trucker traveled for 12 hours.

The kilopascal is a unit of measure for atmospheric pressure. Suppose the atmospheric air pressure at sea level is about

9898

kilopascals. For every 1000-m increase in altitude, the pressure decreases about

11.411.4%.

What is the approximate pressure at an altitude of

40004000

m?

The pressure at an altitude of

40004000

m is about

nothing

kilopascals.

Answers

we know that

At sea level, the height is 0 and
the pressure is 98 kilopascals

At 1000 ft, the height is 1000 and
the pressure decreases about 11.41%

i(100%-11.41%)/100----> (0.8859)

therefore
1) at 1000 ft--------> the pressure is 98*(0.8859)----------> 86.82 kilopascals
2) at 2000 ft--------> the pressure is 86.82*(0.8859)-------> 76.91 kilopascals
3) at 3000 ft--------> the pressure is 76.91*(0.8859)-------> 68.14 kilopascals
4) at 4000 ft---------> the pressure is 68.14*(0.8859)-------> 60.36 kilopascals

the answer is
The pressure at an altitude of 4000 m is about 60.36 kilopascals

The volume of a cone varies jointly with the area of the base and the height. When the area of the base is 27 cm2 and the height is 6 cm, the volume is 54 cm3. Therefore, the area of the base is _____ cm2 when the height is 12 cm and the volume is 124 cm3.

Final answer:

The area of the base of a cone can be calculated by using the volume, height, and a constant derived from given values. Applying this formula to the specified conditions, the area of the base when the height is 12 cm and the volume is 124 cm3 is 31 cm2.

Explanation:

The volume V of a cone can be represented using the formula V = k * B * h, where 'V' is the volume, 'B' is the area of the base, 'h' is the height, and 'k' is a constant proportionality factor. In this case, you are given that the area of the base is 27 cm2, the height is 6 cm, and the volume is 54 cm3. From these values, you can calculate that the constant 'k' is (54/(27*6)) = 0.333. Now, given a volume of 124 cm3 and a height of 12 cm, you can rearrange the equation to solve for the area of the base 'B': B = V/(k*h) = (124/(0.333*12)) = 31 cm2. Therefore, the area of the base when the height is 12 cm and the volume is 124 cm3 is 31 cm2.

HELP PLEASE!! A warehouse holds 460 boxes. They ship out 65 boxes each week. After how many weeks will they have less than 100 boxes remaining. Write and solve an inequality that can be used to determine how many weeks it will take for the warehouse to have less than 100 boxes.

Answers

Let's first define the variables:
x = number of weeks.
y = number of boxes after x weeks.
We write the inequation that adapts to the problem
y> -65x + 460
For a number less than 100 boxes we have:
100> -65x + 460
We clear x:
65x> -100 + 460
65x> 360
x> (360/65)
x> 5.54
Answer:
it will take more than 5.54 weeks for the warehouse to have less than 100 boxes

Final answer:

To determine how many weeks it will take for the warehouse to have less than 100 boxes, we can use the inequality 460 - 65w < 100. Solving this inequality gives w > (460 - 100) / 65, meaning it will take more than 6 weeks.

Explanation:

To determine how many weeks it will take for the warehouse to have less than 100 boxes, we can use the inequality:

460 - 65w < 100

Where 'w' represents the number of weeks. To solve this inequality, we can subtract 460 from both sides and then divide by -65, remembering to reverse the inequality symbol when dividing by a negative number. This gives us:

w > (460 - 100) / 65

So, it will take more than 6 weeks for the warehouse to have less than 100 boxes remaining.
