Jessie Is Building A Cabinet Door, Which Is Pictured Below. The Center Of The Cabinet Door Is 12 Inches

Answers

Answer 1

Answer:

[tex]x^2+14x-51=0[/tex]

Step-by-step explanation:

Since the entire cabinet door is a rectangle, its area is given by:

[tex]A=w\ell[/tex]

The center of the cabinet door measures 12 inches by 16 inches.

And the border of the cabinet door has a width of x inches.

Therefore, the total width of the cabinet door will be (12 + 2x).

Likewise, the total length of the cabinet door will be (16 + 2x).

Thus, the area of the entire cabinet door will be:

[tex]A=(2x+12)(2x+16)[/tex]

We are given that this entire area is 396 square inches. Thus:

[tex]396=(2x+12)(2x+16)[/tex]

Simplify. We can factor out a two from both of the factors on the right-hand side:

[tex]396=2(x+6)(2)(x+8)[/tex]

So:

[tex]396=4(x+6)(x+8)[/tex]

Dividing both sides by four yields:

[tex]99=(x+6)(x+8)[/tex]

Distribute the right-hand side:

[tex]x^2+14x+48=99[/tex]

Therefore, our equation in standard form is:

[tex]x^2+14x-51=0[/tex]

Edit:

We want to find the width of the board. So, we simply have to solve for x. We previously obtained:

[tex]x^2+14x-51=0[/tex]

We can factor:

[tex](x+17)(x-3)=0[/tex]

By the Zero Product Property:

[tex]x+17=0\text{ or } x-3=0[/tex]

Solve for both cases:

[tex]x=-17\text{ or } x=3[/tex]

Length/width cannot be negative. So, we can reject the first solution.

Thus, our only solution is:

[tex]x=3[/tex]

The width of the border of the cabinet door is 3 inches.

This means that the total length of the cabinet is 16 + 2(3) = 22 inches, and the total width of the cabinet is 12 + 2(3) = 18 inches.

Mr Paul has 4 bars of chocolate. He distributes 1/3
of each bar to 4 children.
a) Write the fraction of chocolate distributed.
b) Write the fraction of cholates left with Mr. Paul

Answers

a) The fraction of chocolate distributed is given as follows: 4/3.

b) The fraction of chocolates left with Paul is given as follows: 8/3.

How to obtain the fractions?

The fractions are obtained applying the proportions used in the context of this problem.

He distributes 1/3 of each bar to 4 children, hence the total number of bars distributed is given as follows:

4 x 1/3 = 4/3.

(multiplication of fractions, multiply the numerators and the denominators, keeping the quotient).

The total number of bars that Paul had initially is given as follows:

4 bars.

Then the fraction of chocolate remaining with Paul is given by the subtraction of the total amount of bars by the amount given to the children, as follows:

4 - 4/3 = 12/3 - 4/3 = 8/3 bars.

Answers

The value of the expression 8x² + 6x - 8 below when x=2 is 36.

The value of the expression when x = 2

The expression can be evaluated by following the steps below:

8x² + 6x - 8 in x = 2 means that the variable x will be replaced by the given number which is 2.

8*2² + 6*2 - 8

8*4 + 12 - 8

32 + 16 - 8 = 36

This therefore means that when x= 2 in 8x² + 6x - 8 , the value gotten will be 36.

a. Do the sample data provide convincing evidence that the majority of women age 22 to 35 who work full-time would be willing to give up some personal time for more money? Test the relevant hypotheses using α = .01.
b. Would it be reasonable to generalize the conclusion from Part (a) to all working women? Explain why or why not.

Answers

Answer:

Yes, there is convincing evidence that the majority of women age 22 to 35 who work full-time would be willing to give up some personal time for more money.

No ;

Step-by-step explanation:

n = 1000

x = 545

Phat = x / n = 545/1000 = 0.545

H0: p ≤ 0.5

H1: μ > 0.5

The test statistic :

(phat - p0) ÷ √(p(1 - P0) / n)

Test statistic :

(0.545 - 0.5) ÷ √(0.5(0.5) / 1000)

0.045 / 0.0158113

Test statistic = 2.846

α = 0.01

Decison :

Reject H0 ; if Pvalue < α

Using the Pvalue from Test statistic (Z) calculator :

Pvalue = 0.002214

With Pvalue < α ; We reject H0 and conclude that there is convincing evidence that the majority of women age 22 to 35 who work full-time would be willing to give up some personal time for more money.

Or, we might think of people in boats who litter the waters with their trash. After all, how many times in the news do we hear about ships that leak dangerous chemicals into the water? What we may not realize, though, is that there is another danger that is just as harmful to ocean life as any chemical or other dangerous material: ocean noise.Many of us think of the oceans as silent places. On the contrary, they are filled with a variety of sounds. On any given day, one might hear the calls of dolphins as they swim through the waters. Whales use sounds to keep track of each other. Sea lions talk to each other to find food. Even the tiniest of shrimp make a snapping sound. There are also sounds caused by wind or rain upon the waters. Sound also plays an important role in the daily life of various ocean animals, many of which depend upon their sharp sound detection skills to survive. With increased activities by people on many of the oceans waters, the noise has increased so much that it is beginning to cause damage to the oceans as well as to the animals that live in them.Ocean noise is the term used to describe the human-made noise occurring at increasing rates in the ocean. The noise comes from many different sources: large ships, small boats with motors, and jet skis, among others. There are also underwater exploration activities such as mining, as well as radar activities of ships. One of the most harmful types of ocean noise occurs with offshore oil drilling and seismic oil explorations. Air guns are instruments that are used to determine the location of oil and natural gas beneath the sea floor. They make a sound that can damage the hearing of ocean animals.We know that sound travels faster in water than it does in air. This means that sounds in the oceans can travel for many, many miles in a short period of time. Unfortunately, sounds made by people are much louder than sounds made by ocean animals.What this means is that sounds caused by noisy engines or radar equipment used by ships can upset the everyday activities of the creatures that live in the ocean. For instance, humpback whales use songs to talk to each other. Scientists have discovered that the whales system of talking can be disturbed by loud noises. This makes it harder for the whales to find each other. The stranding of whales and dolphins has been found to increase immediately after naval sonar maneuvers. Sea lions are another type of animal that depends on sounds to communicate with other sea lions. Ocean noise can make it difficult for them to find food. Ocean noise can disturb migration routes of whales and other animals that travel to different places.However, scientists and other researchers are working hard to find a solution to this threat to marine life. Since 2003, the use of low-frequency active (LFA) sonar equipment by the United States Navy has been tightly limited because its effects have been shown to cause harm to many ocean animals. NOAA (National Oceanic and Atmospheric Administration) has released a plan to reduce ocean noise that will work better than past attempts to reduce the noise.Other people are helping as well. Some fishing companies use special equipment that makes a pinging sound to keep certain kinds of ocean life from getting caught in its fishing nets. The National Park Service completed a study that tracked tour cruise ships and made an effort to reduce the number of tours. They also tried to increase the quiet time for humpback whales by scheduling tours farther apart.Local conservation groups are also asking people to be more careful about using jet skis, motorboats, and other equipment that might disturb areas where ocean life is particularly fragile. Also, closer attention is being paid to where ships are traveling to make sure that, whenever possible, they stay away from waters where large numbers of ocean animals live.With the increase in ocean noise, measures must be taken to control or, at the very least, curb its growth.What argument does the author make in "Ocean Noise"?The ocean noise created by marine life is more detrimental than noise created by humans.Oil spills are still much more dangerous than ocean noise.Ocean noise has increased slightly. but it is not affecting marine life.Human activity has greatly increased ocean noise to the detriment of marine life. 25, 22, 21, 23, 24 find the mean What measure do we use to determine the amount of potential energy in a battery?
