Elevators have safety limits for how much weight they can lift. The elevator at the Terrace Hotel can hold up to 2,100 pounds. write an equation or inequality that represents the allowable weight on the elevator at the Terrace Hotel. Graph the solution to the equation or inequality you wrote on the number line. Explain your answer.

Answers

To represent this answer you need to find out what possible numbers of pounds would make this true. In this case, the elevator can hold any number of pounds up to and including 2100 pounds. Attached is a picture of the solutions to your any quality and the actual inequality that represents all of the possible solutions. The idea behind the number line is to show all numbers that are less than or equal to 2100 pounds. The arrow points to the left because numbers to the left are less than The numbers to the right, and we fill in the circle because it includes 2100 as a possible solution.

If the elevator can hold up to 2,100 pounds, that means 2,100 is the maximum. So we have an inequality, not an equation because the elevator can also hold less than 2,100 pounds. Our inequality would represent "less than or equal to".

To write this out, we start with a variable, let's say "w" for "weight".

w

Then, we add our inequality symbol "less than or equal to".

w [tex] \leq [/tex]

Last, we insert our weight limit which is 2,100 pounds.

w [tex] \leq [/tex] 2,100

That represents the inequality for his specific problem. To graph this on a number line, we simply use the symbol that matches "less than or equal to", which is a closed circle. And since we are talking about the weight being LESS THAN, our arrow is going to the left. Attached is an image of how to graph this on a number line.

A model car has a windshield with dimensions 1/18 the size of a real car windshield. The rectangular windshield of the real car has an area of about 2318 sq in, with a width of 61 in. What are the side lengths of the model car's windshield? Round to the nearest hundredth?

Answers

Width of the model car's windshield is around 3.39 inches and the length is approximately 17.45 inches.

The area of the real car windshield is 2318 sq in, with a width of 61 in. The scale of the model car's windshield is 1/18 of the real car windshield.

To find the dimensions of the model car's windshield, first, calculate the area of the model windshield by dividing the real area by the square of the scale factor. Then, find the width and length of the model windshield by using the square root of the calculated area.

In this case, the width of the model car's windshield is around 3.39 inches and the length is approximately 17.45 inches.

Answer:

2.11 inches

Step-by-step explanation:

You want the side length of the windshield of a 1/18 scale model of a car with a 2318 in² windshield that has a width of 61 inches.

Length

The side length of the actual windshield is found from ...

A = LW

L = A/W = (2318 in²)/(61 in) = 38 in

The length of the model windshield is 1/18 of this:

(38 in) × 1/18 = 2 1/9 in ≈ 2.11 in

The side lengths of the model car's windshield are 2.11 inches.

What is the volume of a rectangular prism with side lengths14.7 m, 23.4 m, and 3.2 m?

Answers

think it may be 1100.736 because you would multiply the three numbers

A rectangular prism is a three-dimensional figure; therefore, the units of measure will be cubed when we find our answer. A rectangular prism also has three dimensions that are required to find the volume: Length, Width, and Height. These dimensions must all be multiplied by each other to find the volume. The values for these do not need to be specific; they can be interchanged at any moment. That being said, let's plug in these values for our variables.

Volume = Length x Width x Height; substitute values.
Volume = 14.7 x 23.4 x 3.2; multiply 14.7 by 23.4 first. This allows our units to be squared (units^2).
Volume = 343.98 x 3.2; multiply these two dimensions. This determines our units to be cubed- and furthermore- our volume.
Volume = 1100.736; remember to apply your proper units.

Your answer for this problem is 1100.736 m^3.

A farmer has 300 ft of fencing with which to enclose a rectangular pen next to a barn. The barn itself will be used as one of the sides of the enclosed area.

What is the maximum area that can be enclosed by the fencing?

_______ft^2

Answers

This question can be answered in a number of ways depending on your level of mathematical sophistication (using calculus, graphing a parabola, and guess/check). I'll talk through all three in the order above.

They all start the same way: Let's call the length of the rectangle b and the width a. The perimeter of the rectangle (the distance all the way around -- that is, the length of the "fence") is 2a + 2b. Since the barn is used as one of the sides (let's say b) we can subtract b ... we don't need fencing for this side. That makes the perimeter 2a + b. Since we have 300 feet of fencing we set these equal: 2a + b = 300.

We can solve for b above by subtracting 2a from both sides of the equation so we get: b = 300 - 2a.

We are asked to maximize the area. The area of a rectangle is length times width. In this case, (a)(b) and since we just found an expression for b, we can substitute this to obtain: Area = [tex](a)(300-2a)=300a-2 a^{2} [/tex]. This is a parabola when graphed and we are asked to find where it's highest point occurs because this is where the area is greatest.

METHOD 1: Using Calculus
We are looking for the highest point of the equation [tex]Area = [tex](a)(300-2a)=300a-2 a^{2}[/tex]. Let's call the function R(a) since it is in terms of a. To find the maximum we take the first derivative, set it equal to zero and solve for a. As this is a parabola (with the leading coefficient being negative) it is concave down and the point we find will be the only maximum.

First we find the derivative of the function.
[tex]R(a)=(a)(300-2a)=300a-2 a^{2} [tex]

Next set it equal to 0 and solve for a.
R^{'}(a)=300-4a 0=300-4a -300=-4a 75 = a[/tex] [/tex]
This means that the maximum value (the largest area) occurs when a = 75.
At a = 75 the area is given by
What is the largest area? Let's us substitute 75 for a in the equation of the area. This gives: [tex]Area=a(300-2a)=(75)(300-(2)(75))=(75)(150)=11250[/tex] square feet.

METHOD 2: Graphing
We know that the area is given by. Area = [tex](a)(300-2a)=300a-2 a^{2} [/tex]. To make this more familiar let's use y for the area and x for the width (a). That means we have the equation: [tex](a)(300-2a)=300a-2 a^{2} [/tex].

This is a quadratic equation (the highest exponent of x is 2) and so the equation of a parabola (like the letter U or an upside down U). Since the leading coefficient is negative (-2) we know it opens downward (called concave down -- think of a frown). We are looking for the x-coordinate of the highest point called the vertex. We can find this by remembering that the x-coordinate of the vertex is given by [tex]x= \frac{-b}{2a} [/tex] where a is the leading coefficient the coefficient of the term with the x squared (here = -2) and a is the coefficient of the linear term (the one with x...here 300). That makes the x-coordinate of the vertex [tex]x= \frac{-300}{2(-2)}= \frac{-300}{-4}=75 [/tex].

The y-coordinate of the vertex is found by substituting 75 for x in the equation for the area. [tex]y=300x-2 x^{2} y=300(75)-2(75)^{2} [/tex]
[tex]y=22500- 2(5625) y=22500- 11250 y=11250[/tex]

Since we let x be the width of the rectangle. We know that the width is 75. The area of the rectangle we called y. So the maximum area is 11250 square feet which occurs when the width of the rectangle is 75.

You could have gotten to this point by generating a list of points for the parabola and graphing it carefully on graph paper (though it might not have been exact depending on how you scale your axis).

METHOD 3: Guess and Check
The area of the rectangle is given by Area = [tex](a)(300-2a)=300a-2 a^{2} [/tex]. Here you guess values for a, plug them into the formula to get the area and keep doing this until you are comfortable you have found the largest area. Not the best method but if it's a test and you forget everything else, it might get you close to an answer or even get you the exact answer (depending on how well you guess). It might take a while so I'd do this question last if this were a test.

Two friends work at different companies, P and S. Both companies use the number of hours that an employee works to calculate that employee’s vacation hours. In Company P if you work 10 hours you get 0.4 vacation hours, while in Company S if you work 100 hours you get 7 vacation hours. What is the difference in each friend’s vacation hours if both work 2,080 hours?

Answers

Answer:

62.4 hours

Step-by-step explanation:

For P:

Number of hours off on 10 hours of working=0.4

Number of hours on 2080 hours of working=2080/10*0.4

=83.2 hours

For S:

Number of hours off on 100 hours of working=7

Number of hours on 2080 hours of working=2080/100*7

=145.6 hours

The difference between the vacation hours of P and S is of 62.4 hours. S will get more hours of vacation.

the difference in vacation hours between the two friends is 62.4 vacation hours.

For company P:

We know that 10 working hours give 0.4 vacation hours. So, to find vacation hours for 2080 hours, we can set up the following proportion:

[tex]\frac{10}{0.4} = \frac{2080}{vacation\ hours\ of 2080\ working\ hours}[/tex]

Solving this we get:

[tex]vacation\ hours\ of\ 2080\ working\ hours = \frac{0.4 \times 2080}{10} = 0.04 \times 2080 = 83.2\ days[/tex]

Now for company S:

We know that 100 working hours give 7 vacation hours. So, to find vacation hours for 2080 hours, we can set up the following proportion:

[tex]\frac{100}{7} = \frac{2080}{vacation\ hours\ of 2080\ working\ hours}[/tex]

Solving this we get:

[tex]vacation\ hours\ of\ 2080\ working\ hours = \frac{7 \times 2080}{100} = 0.07 \times 2080 = 145.6\ days[/tex]

Finally, find the difference in vacation hours:

[tex]Difference = 145.6 - 83.2 = 62.4\ vacation\ hours[/tex]

Therefore, the difference in vacation hours between the two friends is 62.4 vacation hours.

Heather was asked to graph 2x + 4y = 12 by using slope and y-intercept. Her graph is shown. Which choice supports the graph that she has drawn. A) The slope is positive 1 2 and the y-intercept is (0,3). B) The slope is negative 1 2 and the y-intercept is (0, 3). C) The slope is positive 1 2 and the y-intercept is (0, -3). D) The slope is negative 1 2 and the y-intercept is (0, -3).

Answers

Answer:

B) The slope is negative 1/2 and the y-intercept is (0, 3).

Step-by-step explanation:

First we rewrite the equation so we can easily find the slope and y-intercept. We do this by isolating the y-term:

2x+4y = 12

We want to subtract 2x from each side:

2x+4y-2x = 12-2x

4y = 12-2x

4y = -2x+12

Now we divide both sides by 4 (everything on both sides gets divided!):

4y/4 = -2x/4 + 12/4

y = -2/4x + 3

y = -1/2x + 3

The slope is -1/2 and the y-intercept is 3 (the point (0, 3)).

Her graph shows the y-intercept at (0, 3); this part is correct.

The graph also shows we go down one and over two between points; this is a slope of -1/2, which is correct.

A soup recipe calls for 23/4 quarts of broth. An open can of broth contains 1/2 quart of broth. How much more broth do you need to make the soup?

Answers

Hey there!

For the beginning of the problem, I believe you meant to type "2 3/4" instead of "23/4". But to solve this, you can subtract the numbers 2 3/4 and 1/2 . . .

3/4 - 1/2 . . .

3/4 = 3/4

1/2 = 2/4

3 - 2 = 1

The denominator stays the same, so that leads you to the fraction 1/4 . . .

2 + 1/4 = 2 1/4.

2 3/4 - 1/2 = 2 1/4

You need 2 1/4 quarts of more broth to make the soup.

Hope this helps you.

The price of a car has been reduced from $19,500 to $16,965. What is the percentage change of the price of the car?

Answers

Hello!

Because the price has been reduced, this is a percent decrease.

To calculate the percentage decrease, we must use a certain formula. The formula is:

[(Old Value - New Value) / Old Value * 100]

Substitute:

[( 19,500 - 16,965) 19,500 * 100] = 13

FINAL ANSWER:

The percent decrease is 13%.

Final answer:

The percentage change in the price of the car is a reduction of approximately 13%, calculated by taking the difference between the original and reduced prices, and then dividing by the original price and multiplying by 100.

Explanation:

To calculate the percentage change in the price of the car, you first find the difference in price and then divide it by the original price. Initially, the car was priced at $19,500 and then reduced to $16,965.

To find the difference, subtract the new price from the old price.

$19,500 - $16,965 = $2,535

Now, divide the difference by the original price and multiply by 100 to get the percentage.

($2,535 ÷ $19,500) × 100 = 13% (approximately)

The percentage change in the price of the car is a reduction of approximately 13%.
