Answer:

B is the answer

Step-by-step explanation:

The distance from boat A to the port is approximately 5.196 miles.

Let's let point P represent the port.

Here A represent boat A and B represent boat B.

It is also given distance between A and B as 12 miles.

Next, we are finding the angles which boat A and boat B make with the line connecting them.

Let's call this line AB.

We can find these angles by subtracting the given bearings from 180 degrees.

For boat A, the angle it makes with AB is 180° - 60° = 120°

For boat B, the angle it makes with AB is 180° - 35° = 145°

Now we can use trigonometry to find the distance from boat A to the port. Let's call this distance x.

We can use the law of sines, which states

sin A / a = sin B / b = sin C / c

where A, B, and C are angles of a triangle and a, b, and c are the side lengths opposite those angles.

In our case, we can use the angle at boat A (which is 60 degrees) and the angle at the port (which is 120 degrees) along with the side opposite the angle at boat A (which is x) and the side opposite the angle at the port (which is 12-x), sin 60° / x = sin 120° / (12 - x)

We are Simplifying,

√3 / x = √3 / (12 - x)

Multiplying both sides by x(12-x),

12√3 - 3x√3 = x√3

Simplifying further,

12√3 = 4x√3

Dividing both sides by 4√3,

x = 3√3

Therefore, the distance from boat A to the port is approximately 5.196 miles.

Answer:

4) 0.4

Step-by-step explanation:

Divide 4 with 9 and you get 0.444444444444444... basically 4 forever

Answer:

add the 11 to both sides to cancel it out.

Step-by-step explanation:

so basically

5x - 11 + 11 = 42 +11

5x = 53

The required first step of solving the given expression is to add 11 on both sides.

Given that,
The first step for the solution of the given expression 5x - 11 = 42 is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
5x - 11 = 42
Add 11 on both sides to reduce the equation as
5x = 53

Thus, the required first step of solving the given expression is to add 11 on both sides.

What does a mathematical expression mean?

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation.

                        This mathematical operation may be addition, subtraction, multiplication, or division.

Given expression is 20x + 12 = 4(_+_). The value of the missing terms will be calculated as,

   2( 6 + x)

  = 12 + 2x

12+2x =  2( 6 + x)

Therefore, the complete expression will be written as 12+2x =  2( 6 + x).

The key here is to have the scores in the same form, let us say decimals for ease of comparison

Jenna: 85% = 85/100 = 0.85

Linda’s= 32/40 = 80% = 0.8

Karl = 7/8 = 0.875

Julie = 0.83

Answer:

P(x=25)=P(z=2)=0.9972 or 99.72%

Step-by-step explanation:

Mean = 18 pounds

Standard Deviation = 3.5 pounds

x= 25

We need to find P(x=25)

First, we need to find z-score using formula: [tex]z-score=\frac{x-\mu}{\sigma}[/tex]

Finding z-score when x=25

[tex]z-score=\frac{x-\mu}{\sigma}\\z-score=\frac{25-18}{3.5}\\z-score=2[/tex]

So, we need to find P(z=2)=P(x=25)

Looking at z-score table we can find P(z=2)

P(z=2)=0.9972 or 99.72%

So, P(z=2)=0.9972 or 99.72%

Answer:

[tex]r\leq 10.8[/tex]

OR

[tex]r\leq 10[/tex]

Step-by-step explanation:

Given that:

Amount of water in the aquarium = 9 gallons

Weight of water in the aquarium = 85 pounds

Total weight that aquarium can hold = 112 pounds

Weight of each rock = 2.5 pounds

To find:

The inequality to find the number of rocks, [tex]r[/tex] that can put in her tank.

Solution:

First of all, let us find more weight that the aquarium can hold after putting the water in the aquarium.

Additional weight that can be put in the aquarium = Total weight - Weight of water = 112 - 85 = 27 pounds

This 27 pounds can be of rocks.

Let the number of rocks that can be put in the aquarium = [tex]r[/tex]

Total weight of [tex]r[/tex] number of rocks = Weight of one rock multiplied by [tex]r[/tex]=2.5[tex]r[/tex]

Now, this weight of rocks must be lesser than or equal to 27 pounds.

Therefore, the in equality is:

[tex]2.5r\leq =27\\\Rightarrow r \leq 10.8\\OR\\\Rightarrow r \leq 10[/tex]
