Answer: 27,600

Step-by-step explanation:

Ok, there could be two answers to this question. If the question is asking how much he would make if it was .15% more, the total would be 27,600/a year

However, if it's asking .15% of 24,000, your answer would be 3,600 ( as in the extra he would be making)

To find the answer, you would have to multiply 24,000*.15 (your starting value times how much you would like to multiply it by)

Find the work W done by a force of 3 pounds acting in the direction 60° to the horizontal in moving an object 4ft (0,0) to (4,0)

Answers

Answer:

[tex]\frac{3}{2}i + \frac{3\sqrt{3} }{2}[/tex]j

Step-by-step explanation:

The work done by the force in moving the object is 10 ft-lb.

What is force?

Force is an influence or interaction that can change the motion or shape of an object with mass.

It can be described as a push or a pull that has both magnitude and direction.

Force is equal to the product of the mass of the object and its acceleration.

Given,

F = 3 p

d = 4 ft

The work formula:  

W = F x d

W = 4 p x cos 60° x 5 ft

= 10 ft lb.

Hence, the work done by the force in moving the object is 10 ft-lb.

Answer:

1. VW = 22

2. x = 87

Step-by-step explanation:

Question 1:

SU = 11 (given)

SU = ½(VW) => midsegment theorem

11 = ½(VW) => Substitution

Multiply both sides by 2

2*11 = VW

VW = 22

Question 2:

UV = x + 13

RT = x - 37

RT = ½(UV) => Midsegment Theorem

x - 37 = ½(x + 13) => Substitution

Multiply both sides by 2

2(x - 37) = x + 13

2x - 74 = x + 13

2x - 74 + 74 = x + 13 + 74

2x = x + 87

2x - x = x + 87 - x

x = 87

Step-by-step explanation:

The length of the altitude of the equilateral triangle is a√3/4 units.

What is a triangle?A triangle is a two - dimensional figure with three sides and three angles.The sum of the angles of the triangle is equal to 180 degrees.∠A + ∠B + ∠C = 180°

Given is to find the length of the altitude of the equilateral triangle.

An equilateral triangle is a triangle whose all sides are equal. All the angles of a given equilateral triangle are 60 degrees.

The length of the altitude of the equilateral triangle can be found out using the Pythagoras theorem.

Draw a median from one vertex on the opposite side to that vertex and apply Pythagoras theorem to one of the right triangle.

We can find the length of the altitude to be -

L = a√3/4

Therefore, the length of the altitude of the equilateral triangle is a√3/4 units.

The ideal output of a particular oil-rig in the Mexican Gulf is at least 2000 barrels per day. If the output is lesser than that, the foreman raises an red flag at the end of the day.

Could Joe conclude that the oil-rig is operating at a non-ideal condition most of the time

Answers

Answer:

Mexican Gulf Output of a Oil-Rig

Based on 57% red flag days, Joe, the retired statistician, who watches from the shore for the red flag every day, cannot conclude that the oil-rig is operating at a non-ideal condition most of the time, but more of the time.

Step-by-step explanation:

Ideal output of a particular oil-rig, at least = 2,000 barrels per day

When output is lesser than 2,000, a red flag is raised by the foreman

Number of days counted = 28

Number of days when red flag was raised = 16

Proportion of days when the red flag was raised = 16/28

= 0.57

Answers

Answer:

  40.5 square inches

Step-by-step explanation:

The figure appears to be a trapezoid with bases 15 inches and 12 inches, and a height of 3 inches. The formula for the area of a trapezoid is useful in this case:

  A = 1/2(b1 +b2)h

  A = (1/2)(15 in +12 in)(3 in) = (1/2)(27 in)(3 in) = 40.5 in²

The area of the composite figure is 40.5 square inches.

__

Additional comment

You get the same answer if you divide the figure into a rectangle and a triangle. The rectangle is 3 in high by 12 in long, so has an area of ...

  A = bh = (12 in)(3 h) = 36 in²

The triangle has a base of (15 -12) = 3 in, and a height of 3 in. It has an area of ...

  A = 1/2bh = 1/2(3 in)(3 in) = 4.5 in²

Then the total area is the sum of the rectangle and triangle areas:

  figure area = 36 in² +4.5 in² = 40.5 in²

Sully is having a party and wants to fill his swimming pool. If he only uses his hose, it takes 3 hours more than if he only uses his neighbor's hose. If he uses both hoses together, the pool fills in 5 hours. How long does it take for each hose to fill the pool (in hr)?

Answers

Answer:

It takes the neighor's hose 3 hours to fill the pool and it takes Sully's hose 6 hours to fill the pool if each filled alone.

Step-by-step explanation:

This is a work problem, and the way these are done is to figure the amount that each can do based on how much can get done in a single hour.  

First thing, in order to have only one variable, we have to put one hose in terms of the other hose.  

We know that it takes the neighbor's hose a certain amount of time (there's our unknown) to fill the pool and that it takes Sully's hose that same time plus 3 hours.

neighbor's hose can get the job done in x time

Sully's hose can get the job done in x + 3 time

Now we will figure out how much each can do in a single hour.

If the neighbor's hose takes x hours to fill the pool, then it can get

of the pool filled in 1 hour.

If Sully's hose takes x + 3 hours to fill the pool, then it can get

of the pool filled in 1 hour.

The sum of these takes 2 hours total and 1/2 of the pool gets filled in 1 hour.

Our equation then is:

This equation states in words:

"the amount of the pool that the neighbor's hose can fill in an hour plus the amount of the pool that Sully's hose can fill in an hour will fill half the pool".

Solving for x will give us that time.

Begin to solve this by finding the LCM of those denominators and getting rid of the fractions by reducing.  The LCM will be 2x(x + 3).  Multiplying each term by that LCD looks like this:

In the first term the x's cancel out, in the second term the (x + 3) cancels out, and in the last term the 2's cancel out leaving us with:

and simplifying gives us:

This is a quadratic that will have to be factored to solve for those values of x.  Combine like terms and get everything on one side to get:

Factor this however you find easiest to get the values:

x = 3 hours and x = -2 hours

We all know that the 2 things in math that will never EVER be negative are times and distances/measures, so we can disregard the -2 and say that

x = 3 hours.  

To answer our question, then;

It takes the neighbor's hose 3 hours to fill the pool; it takes Sully's hose 3+3 hours = 6 hours to fill the pool.

Step-by-step explanation:

Given

[tex]\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {14} & {13} & {12} & {11} & {10} \ \\ A & { } & { } & { } & { } & {50}\ \end{array}[/tex]

Required

Complete the table of Areas

Using the complete column:

Where x = 5, y = 10 and A = 50,

We can deduce that, the area is calculated as:

[tex]A = 5 * 10 = 50[/tex]

i.e.

[tex]A = x * y[/tex]

So, for other values of x and y, the area is calculated as thus:

[tex]x = 1; y = 14[/tex]

[tex]A = 1 * 14 = 14[/tex]

[tex]x = 2; y = 13[/tex]

[tex]A = 2 * 13 = 26[/tex]

[tex]x = 3; y=12[/tex]

[tex]A = 3 * 12 = 36[/tex]

[tex]x =4;y =11[/tex]

[tex]A = 4 * 11 = 44[/tex]

So, the complete table is:

[tex]\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {14} & {13} & {12} & {11} & {10} \ \\ A & {14} & {26} & {36} & {44} & {50}\ \end{array}[/tex]
