Step-by-step explanation:

Using vector concepts, it is found that:

The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.

Given a magnitude M and angle [tex]\theta[/tex], then a vector V can be represented as follows in component notation:

[tex]V = (M\cos{\theta}, M\sin{\theta})[/tex]

In this problem, the magnitude and the angle are given, respectively, by:

[tex]M = 12, \theta = 143^\circ[/tex]

Hence:

V = [12cos(143º), 12sin(143º)] = (-9.58, 7,22).

Which means a displacement of 9.58 miles to the west(negative x = west) and 7.22 miles to the north(positive y = north).

The component form is of approximately (-9.58, 7,22). It means that the ship is about 9.58 miles to the west and about 7.22 miles to the north of where the ship left the port.

Using proportions, it is found that one mechanic could assemble 5 bicycles in 8 hours, and it would take 40 hours to assemble 25 bicycles.

The equation is: b = 0.625t.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, two mechanics can assemble 10 bicycles in 8 hours. How many bicycles could one mechanic assemble in 8 hours? Hence the rule of three is given by:

2 mechanics - 10 bicycles.

1 mechanic - x bicycle.

Applying cross multiplication:

2x = 10 -> x = 5 bicycles in 8 hours.

Hence the equation for the number of bicycles in t hours of a single mechanic is given by:

b = 5/8t = 0.625t.

For 25 bicycles, we have that:

25 = 0.625t.

t = 25/0.625.

t = 40 hours.

Answer:  59.690260418206

The result is approximate. Round that value however you need to.

===========================================================

Explanation:

For a circle with radius r = 142.5, the full distance around the edge (aka perimeter aka circumference) is found by using the formula below.

C = 2*pi*r

C = 2*pi*142.5

C = 895.353906273091

That value is approximate. I used my calculator's stored value of pi to get the most accuracy possible.

That value of roughly 895 represents the distance around a full circle of that radius, but we only want a 24 degree pizza slice.

In other words, we want 24/360 = 1/15 of the full perimeter

(1/15)*895.353906273091 = 59.690260418206

Answer:

59.69 units

Step-by-step explanation:

TOTAL circumference of this circle = pi * d = pi * 2r = 895.354

  now you  want 24 degrees of the entire 360 degrees

       24/ 360   *    895.354 = 59.69 units

The angle OBC is 90 degrees, the equation is 18r = 144, r = 8 feet, and the length of the AB is 16 feet which is the length of the red sail in the logo.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have the figure shown in the picture with dimensions.

a) As we can see, the AOB is the diameter of the circle which is perpendicular to the CBD

So the angle ∠OBC will be a right angle.

∠OBC = 90 degree.

b) Length OE is the radius of the circle.

Let's suppose OE = r

Then in a right angle triangle OBC where ∠OBC = 90 degrees.

Applying Pythagoras theorem:

OC² = CB² + OB²

(CE + OE)² = CB² + OB²

CE = 9 ft, OE = r, CB = 15 feet, and OB = r (radius of the circle)

(9 + r)² = 15² + r²

81 + 18r + r² = 15² + r²

18r = 144

r = 8 feet

OE = r = 8 feet

c)

As the angle ∠OBC = 90 degrees, that's why the triangle OBC becomes a right angle triangle and OB⊥CB.

d)

In the circle, there is a red triangle, we can find one of the lengths of the triangle which is AB.

AB is the diameter of the circle

r = 8

Diameter AB = double the radius = 2(8) = 16 feet

AB = 16 feet

Thus, the angle OBC is 90 degrees, the equation is 18r = 144, r = 8 feet, and the length of the AB is 16 feet which is the length of the red sail in the logo.

The solution to this system of equations is: The solution (25, 20) tells the contractor the number of hours on a job where the hourly rate is the same for both billing options. (Option C).

It means that if the number of hours worked is above 20, then it is more profitable to utilize the $20/hour rate.

Recall that the contractor has two options for billing a completed job. They are:

Let us fix x hours to be required for completing the project:

Note that:
The total amount recievable per contract is $500 while working on a retail basis, it will cost $25x.

Stating this mathematically, e have

25x < 500 when x < 20.

This mean that

25x < 500 when x < 20.

Then we find that by I contract he would get 500 $ but by II choice he would get 25x dollars

We find that

25x<500 if x<20

This suggests that a $500 flat rate is preferable if the number of hours done is fewer than 20.

Hence the correct answer is Option C.
