the captain the chief mate the chief engineer walk around the deck of the ship it takes 4 minutes to the captain to circle the deck of the ship chief mate takes 5 minutes chief engineer takes 6 minutes how many minutes will they meet again at starting point
Answer:
60 minutes
Step-by-step explanation:
Step 1
We Find and list multiples of each number of minutes that each person walked around the deck until the first common multiple is found. This is the lowest common multiple.
Multiples of 4:
4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68
Multiples of 5:
5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70
Multiples of 6:
6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72
Therefore,
LCM(4, 5, 6) = 60
They would meet again at starting point after 60 minutes

It is estimated that 26% of the population of Gingerland have red hair. If 10 residents are chosen at random, what is the probability that... (assume each person is independent)
a) exactly 4 of them have red hair?
b) less than 5 of them have red hair?
c) at least one of them has red hair?
d) What is the expected (mean) number of people you will find with red hair in this group of 10?
Answer:
The answer for me would be a) exactly 4 of them have red hair
Step-by-step explanation:
being that there is 26 percent of people in Gingerland that gave red hair I cam assume that that is a lot of people being that Gingelrand is like a city/town so exactly 4 of them is what I assume is the amswer

HELP ME PLEASEEEEEEEEEEEE
Answer:
m<1 = 54
m<3 = 54
m<4 = 126
Step-by-step explanation:
<1: <2 and <1 are supplementary angles.
<3: <2 and <3 are supplementary angles. <1 and <3 are vertical angles.
<4: <2 and <4 are vertical angles.
Supplementary angles equal to 180 degrees.
Vertical angles are equivalent.
Let's solve for <1.
<2 + <1 = 180 --> Due to supplementary angles
126 + <1 = 180 --> Substitution
126 + <1 - 126 = 180 - 126 --> Subtracted 126 on both sides
<1 = 54 --> Simplified
Let's solve for <3.
<3 = <1 --> Due to vertical angles
<3 = 54 --> Substitution
Let's solve for <4.
<4 = <2 --> Due to vertical angles
<4 = 126 --> Substitution
Therefore, m<1 = 54, m<3 = 54, and m<4 = 126
Hope this helped! <3
Answer:
1 is 54 degrees
3 is also 54 degrees
4 is 126 degrees

What is the slope of the line?
Answer:
0
Step-by-step explanation:
The slope formula is (change in y)/(change in x)
since the numerator (change in y) is 0, the slope will be 0
Find the value of a.
Answer: 14
Step-by-step explanation: The perimeter is all of the side added together. When finding the perimeter of a rectangle the opposing sides have the same value. So the equation would be 2(12) + 2(a) = 52. 12 x 2 is 24. 52- 24 is 28 and youre left with 28 = 2(a). You divide each side by 2 and get 14 = a
the spinner below is spun then the a month of the year is randomly selected. Find each probability

Sorry if am wrong.
Answer:
Step-by-step explanation:
P (blue) fraction = 2/8 decimal=.25 percent=25%
P(purple) fraction=0/8 decimal=0 percent =0%
P(not green) fraction=5/8 decimal=.625 percent= 62.5%
P(not brown) fraction=8/8 decimal=1 percent =100%
2)Refer to the table on air travel selected airports. Suppose a flight that arrived at El Centro is selected at random. What is the probability that the flight did not arrive on time? write your answer as a fraction, decimal and percent.
80% on time so 20% are not on time
20/100 ÷ 20 =1/5
20%, .2, 1/5

I really need help for this question, I would appreciate any help thank you.
Answer:
Step-by-step explanation: so a straight line always equals to 180 where 41 is its a straight line so we know the total should be 180 degrees so to find x you need to subtract 180 minus 41 which equals 139 which is your answer im not super sure but trust your gut im trusting mines with this one so i hope this helps
Please help I don’t understand
Answer:
1/2
Step-by-step explanation:
y = mx + b
the "m" is the slope
and the b is the y-intercept
as you can see from the equation y = 1/2x + 3
the 1/2 substituted the m which is the slope
so the slope of the line is 1.2
