The relationship between the time since Captain Summers became a ship captain and his total number of hours at sea can be modeled by the equation y = 800x + 2200, where x is the time since he became a ship captain in years and y is his total number of hours at sea. How many hours at sea did Captain Summers have when he first became a ship captain?

Step-by-step explanation:

Vamsi is X years old

Vamsi = X

his brother is 3 years elder to him

Brother = X + 3

his uncle is 4 times his age

Uncle = 4X

his aunt is 5 years younger than his uncle

Aunt = Uncle - 5

what will be the age of his uncle 6 years from now

= 4X + 6

what are the ages of vamis brother, uncle and aunt?

Assume Vamis = 15 years

Brother = X + 3 = 15 +  3 = 18

Uncle = 4X = 4 * 15 = 60

Aunt = Uncle - 5 = 60 - 5 = 55

what will be the age of his uncle 6 years from now

Uncle = 4X + 6 = 60 + 6 = 66

Answer:

0.484 g

Step-by-step explanation:

N/No = (1/2)^t/t1/2

No = mass of cesium-137 originally present

N= mass of cesium-137 at time t

t1/2= half life of cesium-137

t = time taken

N/5.5=(1/2)^105/30

N/5.5=(1/2)^3.5

N/5.5= 0.088

N = 5.5 *  0.088

N= 0.484 g

Answer:

x > 25

Step-by-step explanation:

3(2x−8)>4x+26

Step 1: Simplify both sides of the inequality.

6x−24>4x+26

Step 2: Subtract 4x from both sides.

6x−24−4x>4x+26−4x

2x−24>26

Step 3: Add 24 to both sides.

2x−24+24>26+24

2x>50

Step 4: Divide both sides by 2.

2x

2

Answer:

Quadrant III

Explanation:

The positives-negatives value rule in quadrants:

Quadrant I = ( + , + )

Quadrant II = ( - , + )

Quadrant III = ( - , - )

Quadrant IV = ( + , - )

Answer:

∅ = 22.33°

Step-by-step explanation:

tan 28° = h/15

0.5317 = h/15

h = 7.98

sin ∅ = h/21

sin ∅ = 7.98/21

sin ∅ = 0.38

∅ = 22.33°

Answer:

I believe it should be 5.882%

Step-by-step explanation:

This is how i got tought to do it

85-80=5

5/85=0.05882

0.05882 times 100=5.882%

and that's your answer hope you get it right.

Answer:

Step-by-step explanation:

The general steps are ...

It is generally convenient to put the variable terms on the side of the equation having the largest (most positive) variable term. You do the rearranging by subtracting the terms you don't want. Any operation is performed on both sides of the equation.

__

1) 3x + 7 = 4x

We observe the largest x-term is on the right, and the only constant term is on the left. We can subtract the x-term 3x to eliminate it from the left side

  3x +7 -3x = 4x -3x

Combining like terms gives ...

  7 = x . . . . . this is the solution

__

2) x +2 +2x = x + 10

We observe x-terms and constants on both sides of the equation. First of all, we will combine like terms.

  3x +2 = x +10

The largest x-term is on the left, so we choose to subtract x (the x-term on the right)

  3x -x +2 = x -x +10

  2x +2 = 10

We don't want the constant on the left, so we subtract 2.

  2x +2 -2 = 10 -2

  2x = 8 . . . . . . . . . . combine like terms

Now, we divide by the coefficient of x.

  2x/2 = 8/2

  x = 4 . . . . . . the solution

__

3) x +3x = x + x + 10

  4x = 2x +10 . . . . . . . combine like terms

  2x = 10 . . . . . . . . . . . subtract 2x

  x = 5 . . . . . . . . . . . . . divide by 2

__

4) 2x +3 + 3x = x + 11

  5x +3 = x +11 . . . . . . . . combine like terms

  4x +3 = 11 . . . . . . . . . . . subtract x

  4x = 8 . . . . . . . . . . . . . . subtract 3

  x = 2 . . . . . . . . . . . . . . .divide by 4

_____

Learn to identify and combine like terms. Use addition or subtraction to eliminate terms you don't want. Use multiplication or division to eliminate coefficients you don't want. Whatever you do to one side of the equation must also be done to the other side of the equation. (In the above, we use "subtract ..." to mean "subtract ... from both sides of the equation," for example.)

Answer:

You may have gotten the opposite and adjacent mixed up.

[tex]\frac{24}{7}[/tex]

Step-by-step explanation:

An easy way to remember these trigonometric ratios is by using SOHCAHTOA, where:

SOH stands for-

[tex]Sine=\frac{Opposite}{Hypotenuse}[/tex]

CAH stands for-

[tex]Cosine=\frac{Adjacent}{Hypotenuse}[/tex]

TOA stands for-

[tex]Tangent=\frac{Opposite}{Adjacent}[/tex]

We are asked to find tan 74° given the right triangle. To find this, we must find the lengths of the opposite side and the adjacent side of the 74° angle. From looking at the triangle, we can see that the side opposite from the 74° angle is 24, and the adjacent is 7. So plugging it into the trigonometric ratio that we found using SOHCAHTOA, we find that:

[tex]tan74=\frac{24}{7}[/tex]

So the answer would be [tex]\frac{24}{7}[/tex]

Seeing as how you picked [tex]\frac{7}{24}[/tex] as your answer, it seems that you may have gotten the opposite and the adjacent mixed up or used [tex]tangent=\frac{adjacent}{opposite}[/tex] as your trigonometric ratio.

I hope you find my answer and explanation to be helpful. Happy studying.
