Explanation:
p = number of passengers
L = number of lifeboats
Since we're grouping the passengers in groups of 12, this strongly implies we'll be dividing two values. Specifically we have p divided by 12 to represent the number of boats we will need just for the passengers.
For example, let's say p = 36. This means we have 36 passengers. That would mean we need p/12 = 36/12 = 3 boats for those 36 passengers. This excludes the crew and backup boat. Adding those two extra boats leads to the expression 2 + p/12 which is the total number of lifeboats needed.
In the event that p is not a multiple of 12, this leads to p/12 not being a whole number. We could have say p = 50 passengers which means p/12 = 50/12 = 4.167 approximately. We will not round this to 4 because then we'll have passengers without a lifeboat.
We must round 4.167 up to the nearest whole number to get 5. The first four boats take care of 4*12 = 48 passengers, while that 5th boat handles the remaining 50-48 = 2 people. Since 2 people in a boat seems like a really low count, the crew could likely spread the people out such that say 10 people would be in each boat (since 50/10 = 5).
So in short, the result of p/12 is rounded up to the nearest whole number.
help a girl out What is the slope of a line that would be perpendicular to line k?
Answer:
( -2 , -2 ) or ( 2 , 4 )
Step-by-step explanation:
Answer:
4-1/2-0 = 3/2
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today. What is the percentage increase of
amount of peas picked by Rim
Given:
Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.
To find:
The percentage increase of amount of pears picked by Kim.
Solution:
We know that,
[tex]\%\text{ increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]
[tex]\%\text{ increase}=\dfrac{287-250}{250}\times 100[/tex]
[tex]\%\text{ increase}=\dfrac{37}{25}\times 10[/tex]
[tex]\%\text{ increase}=\dfrac{370}{25}[/tex]
[tex]\%\text{ increase}=14.8[/tex]
Therefore, the percentage increase of amount of pears picked by Kim is 14.8%.

Work out the volume of this sphere.
Give your answer to 1 decimal place.
Spheres
Vol = ener
7 cm
Answer:
Volume of the sphere ( V ) = 1436.02 cm³
Step-by-step explanation:
Explanation:-
Given that the radius of the sphere r = 7 cm
Volume of the sphere
[tex]V = \frac{4}{3} \pi r^{3}[/tex]
[tex]V = \frac{4}{3} \pi (7)^{3}[/tex]
[tex]V = \frac{4}{3} X3.14 X (7)^{3} = 1436.02[/tex]
V = 1436.02 cm³
Volume of the sphere
V = 1436.02 cm³
Answer:1436.8
Step-by-step explanation:
4/3πr^3
Substitute the 7 with the ”r”
4/3xπx7^3
=1436.8 (to 1 decimal place)

Answer:
x = 1/2
b = 12
Step-by-step explanation:
In order to solve for x you have to divide by x
2 = 4x divide by x
2/4 = x
simplify and you get 1/2
same thing goes for b. You need to leave b by itself. so subtract 24 from both sides and you get -12. divide both sides by -b and a negative divided by a negative turns into a positive b by it self holds a value of 1
Answer:
the answer to question 5 is 0.5 and to question 6 it is 36
Step-by-step explanation:
becuase for number five u have to cancel out the 4 to have the variable by itself sonu divide it and u get 0.5 and for number 6 you do the same but add 24 to 24 ti cancel it out and then when you add 24 to 12 its 36 becuase what you do to one side u have to do to both . hope I helped :)

Answer:
30 m²
Step-by-step explanation:
The figure can be divided into two parts.
The top rectangular part with its width as : w= 2m and length, l= 9 m
The area , A = l * w = 2*9 = 18 m²
The bottom rectangular part has its width as : w= 2m and length , l = 6 m
The area , A = l*w = 2*6 = 12 m²
Total area is given as :
18 + 12 = 30 m²

Graph the line that passes through the points (-9,5) and (-9,-5) and
determine the equation of the line.
Answer:
x=-9
Step-by-step explanation:
M(slope)=y2-y1/x2-x1
m=-5-5/-9+9
m= -10/0
This means the slope is undefined. Whenever the slope is undefined, the line is vertical and is passing through the x-axis and parallel to the y-axis. Take the given coordinate (-9,5) and all you do is put x= -9. That's the equation of the line.

Find the slope of the following graphs.
A. 2/3
B. 3/2
C. 3
D. - 2/3
Answer:
Answer is A
Step-by-step explanation:
The slope of the shown line passing through points (3,2) and (0,0) is 2/3. The answer is option A.
Given the points (3,2) and (0,0), we can calculate the change in y and change in x as follows:
Change in y = 2 - 0 = 2
Change in x = 3 - 0 = 3
Now, we can substitute these values into the slope formula:
Slope = (change in y)/(change in x) = 2/3
Here, the line has a positive slope, indicating that as x increases by 1, y increases by 2/3.
This means that the line is ascending from left to right, sloping upwards.
Therefore, the slope of the line passing through points (3,2) and (0,0) is 2/3.
Hence, the answer is option A.

What is the slope of a line parallel to the line whose equation is x+2y=10
Answer: slope =
-1/2
Step-by-step explanation:
Since they are parallel, they will never intersect. The only way this is possible is if they have the same slope. All you had to do was get y by itself and find the number next to the x. Subtract the ten and the 2y and pass them to their opposite sides that way it will be x-10= -2y. After that, divide the -2 by everything on the x side. The final equation is -1/2x -10= y.
Twice the difference of 1 and a number.
