A ship must have 1 lifeboat for every 12 passengers, plus one lifeboat for
the crew and one backup lifeboat. Which equation shows the
relationship between the number of passengers, p, and the number of
lifeboats needed, I?
Select one
1) I= 2 + 1/2
2) I= 2p + 10
3) I= 12p
4)I=2+ p/12
===========================================
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.

Answer:
41.13
Step-by-step explanation:
The figure is basically 8+8+circumference of a circle with 8 diameter. The circumference is 2pi(4) which is 50.27, and you add 16 to that. This gives you the answer 41.13
Thanks to garden555 for pointing out my mistake.
Answer:
60m / 41.12 m
Step-by-step explanation:
side of square is 8m
hence, radius of the semicircle is 1/2 of 8
= 4m.
2semicircles = 1 circle.
perimeter of a circle = 2πr
Taking value of π as 22/7,
= 2 x 22/7 x 4
= 176/4
= 44m
OR
Taking value of π as 3.14,
= 2 x 3.14 x 4
= 25.12m
hence, perimeter of figure is,
44 + 8 + 8 = 60m
OR
25.12 + 8 + 8 = 41.12 m
The weight of a baby dog on day one is 5 kilograms. Every day, the dog grows an additional 0.1 kilograms. How heavy the dog is after 10 days?
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The weight of the dog after 10 days is 5.9 kg.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Weight of the baby on day one = 5 kg
This can be written as,
1 day = 5 kg
The dog grows 0.1 kg each day.
This means,
On the 2nd day, we get,
2 days = 5 + 0.1
2 days = 5.1 kg
The expression for the weight of the dog on n days can be written as,
n days = 5 + (n -1) x 0.1 _____(1)
Now,
After 10 days we get,
n = 10
From (1) we get,
10 days = 5 + (10 - 1) x 0.1
10 days = 5 + 9 x 0.1
10 days = 5 + 0.9
10 days = 5.9 kg
Thus,
The weight of the dog after 10 days is 5.9 kg.

Answer:
x = 12
Step-by-step explanation:
18:24 (comparing the same sides for the similar shapes; 18 and 24) when simplified down is equal to 3:4.
Using this 3:4 scale factor we can find the missing side x.
Solving for x :
[tex]\frac{3}{4}[/tex] × 16 = 12
x = 12
OR: Set up a proportion:
[tex]\frac{24}{16}[/tex] × [tex]\frac{18}{x}[/tex]
cross-multiply
16 × 18 = 288
24 × x = 24x
288 = 24x
x = 12
