1/6 of a ship's crew are engineers, 1/4 are stewards and the rest are soldiers. if there are 48 crew members in all, how many sailors are on the board of the ship?

Answers

Answer 1

Answer: $1/6 + 1/4 \n = 2/12+ 3/12 \n = 5/12 \n \n 1-5/12 \n = 12/12 -5/12 \n =7/12$

$7/12*48=28$

The answer is 28.

Answer 2

Answer: $(1)/(4) + (1)/(6) = (6+4)/(24)= (10)/(24) = (5)/(12) \n \n 1- (5)/(12)= (7)/(12) \n \n 48* (7)/(12) =28$

plz answer all of above

Answers

difference means subtraction so
decreased means subtraction
more than means addition

1. 42-19 = 23

2. 2100-77 = 2023

3. 330+20 = 350

I'm so confused can someone help me with number 4

Answers

Ok so first with a you have
a=2 b=5 c=7
and the problems are 2a+10 and 2b+c
Well to do this we are going to right 2a+10 as 2*a+10
So now lets replace a.
and since a=2 we have 2*2+10
2*2=4+10=14
So A is 14
and now for be we have 2b+c
Lets re-write it as 2*b+c
and now replace
2*5+7
2*5=10+7=17
b is 17.
Now with the next (4)
For a it is x=7
Subtract 3x from both sides.
Subtract 5 from both sides.
x=7
and for B
x=3
Subtract 3x from both sides.
Add 10 to both sides.
Divide both sides by 4.
x=3
Hope this helps!

Lara tossed a fair coin 3 times. What is the probability of getting heads in the first two trials?1 over 8

2 over 8

3 over 8

4 over 8

I tried 4/8 and I had gotten it wrong!

The probability of getting heads in the first two trials is 2/8.

What is the probability of getting heads in the first two trials?

Probability calculates the chances that an event would happen. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

Probability of getting heads = heads , heads, tails, tails

This is a 25% probability which is equivalent to 2/8.

4/8 is equal to 1/2. While this is true of one coin toss, it is not a 50% chance if you toss the coin twice. In tossing the coin twice you have the options of: heads, tails, heads, tails (One head and one tail per coin). Since there are four options, it is a 25% chance you will get heads twice in a row. 25% equals 1/4 which equals 2/8.

What is the volume of this equation?A four- sided pyramid with base edge of 5 ft and h = 4 ft

Answers

Answer:

Volume ≈ 33.33 cubic feet

Step-by-step explanation:

The question is:

Find the volume of a right square pyramid with base square edges measuring 5 feet each and a height of the pyramid be 4 feet.

So, the base is a square with side length 5 feet.

And the height of the pyramid is 4 feet.

The volume of a pyramid is given by the formula:

$V=(a^2 h)/(3)$

Where

a is the square base side length (given as 5)

h is the height of the pyramid (given as 4)

Now we substitute and find the value:

$V=(a^2 h)/(3)\nV=((5)^2 (4))/(3)\nV=33.33$

The volume is around 33.33 cubic feet

Answers

Answer:

Step-by-step explanation:

the answer would be C, or y = 0.125x + 625 because in the problem, it says that the store would require an upfront payment of $25 PLUS $50 a month, then 12.5% interest at the end of the year, then it asks what the equation would be after 12 months. SO we know that is a year (since there are 12 months in a year) so we would multiply that by number by the $50 we would have to pay a month which would look like this: 12 months x $50 a month = $600. then, we would add the initial $25 dollars, which would give us a total of $625 which we'd add to the equation. next, if we look at 12.5% and then at our answer choices, we can see that they converted the percent to a decimal. 12.5% is equivalent to 0.125, therefore our final answer is C!

i hope this helps :D
