Answer and Step-by-step explanation:

Trigonometric Function (These only work for right triangles):

SOH-CAH-TOA

S = Sine = sin

C = Cosine = cos

T = Tangent = tan

O = Opposite (side)

H = Hypotenuse (side)

A = Adjacent (side)

SOH = sin(angle) = [tex]\frac{opposite}{hypotenuse}[/tex]

CAH = cos(angle) = [tex]\frac{adjacent}{hypotenuse}[/tex]

TOA = tan(angle) = [tex]\frac{opposite}{adjacent}[/tex]

1. sinQ (Q is the angle) = [tex]\frac{14}{50} = \frac{7}{25} = 0.28[/tex]

Use Pythagorean Theorem to find side PQ.  [tex]14^{2} + PQ^{2}= 50^{2} \\PQ^{2} = 2304\\PQ = 48[/tex]

2. cosQ = [tex]\frac{48}{50} = \frac{24}{25} = 0.96[/tex]

3. tanQ = [tex]\frac{14}{48} = \frac{7}{24} = 0.29[/tex]

Deb is searching online for airline tickets. Two weeks ago, the cost to fly from Hartford to Boston was
$210. Now the cost is $335. What is the percent increase? What would be the percent increase if the
airline charges an additional $50 baggage fee with the new ticket price?
The percent increase of the airline ticket is %.
(Round to the nearest percent as needed.)

Answers

Answer:

Percent increase = 60%

Percent increase with baggage = 83%

Step-by-step explanation:

Given that:

Old price of the ticket = $210

New price of the ticket = $335

Increase amount =335-210 = $125

Percent increase = [tex]\frac{Inrease\ amount}{Old\ price}*100[/tex]

Percent increase = [tex]\frac{125}{210}*100 = 0.595*100[/tex]

Percent increase = 59.52% = 60%

Additional charges = $125+$50 = $175

Percent increase = [tex]\frac{175}{210}*100[/tex]

Percent increase = 83%

Hence,

Percent increase = 60%

Percent increase with baggage = 83%

Clay at each work station =  [tex]\dfrac1{32}[/tex] pound

Total work stations = (Total clay ) ÷ (Clay at each work station )

a 20% sugar syrup is mixed with 10% sugar syrup.The result is 600 g of 12% sugar syrup. How many grams of each syrup are in the mixture.

Answers

Answer:

120 grams of 20% sugar and 480 grams of 10% sugar

Step-by-step explanation:

The reason that the answer is what it is is because the total of the sugar syrup must be 600 grams. It is 12% which means that its 1/5 20% and 4/5 10% and if you divide 600 by 5 you get 120 therefore 120 grams of 20% sugar is correct and for the rest just subtract 120 from 600 the get the answer.

There are 120 g of 20% sugar syrup and 480 grams of 10% of sugar syrup.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

A 20% sugar syrup is mixed with 10% sugar syrup.

And, The result is 600 g of 12% sugar syrup.

Now,

It is 12% which means that its 1/5 of 20%.

Hence, Amount of sugar grams = 600 / 5

                                                  = 120 grams

And,  It is 12% which means that its 4/5 of 10%.

Hence, Amount of sugar grams = 600 / (4/5)

                                                  = 480 grams

-5(n-1)=7(n+3)
Solve for the missing variable please help!

Answers

Answer:

n = - [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

Given

- 5(n - 1) = 7(n + 3) ← distribute parenthesis on both sides

- 5n + 5 = 7n + 21 ( subtract 7n from both sides )

- 12n + 5 = 21 ( subtract 5 from both sides )

- 12n = 16 ( divide both sides by - 12 )

n = [tex]\frac{16}{-12}[/tex] = - [tex]\frac{4}{3}[/tex]

Answer:

Step-by-step explanation:

To solve this you have to use the distributive property.

So first you would distribute the -5 to n and -1.

So the new equation will be -5n + 1 = 7 (n + 3)

Next, distribute the 7 to n and 3.

The new equation will be -5n + 1 = 7n + 21

Next you simplify by adding 5n to both sides which will give you 1 = 12n + 21

Then you subtract 21 from both sides and get -20 = 12n

So then you divide both sides by 12 to get n by itself and you are left with  -5/3 = n

Solve the system of linear equations. Y=-1/6x+5 and x+6y=30 Can you explain the steps?

Answers

Answer:

Infinitely many solutions

Step-by-step explanation:

y = -1/6x + 5

x + 6y = 30

We can solve this system by using substitution or elimination. Since we are given an isolated y-value, I'll be using the substitution method.

Substitute y = -1/6x + 5 into the second equation for y.

x + 6(-1/6x + 5) = 30

Distribute 6 inside the parentheses.

x - x + 30 = 30

Combine like terms.

30 = 30

Since this is a true statement, we can conclude that this system has a solution of all real numbers, or infinitely many solutions.

We can also see that these equations are indeed equivalent by multiplying the top equation by 6.

6 * (y = -1/6x + 5) → 6y = -x + 30

Adding x to both sides and rearranging terms gives us x + 6y = 30, which is the same as the second equation.

What type of philosopher was Plato?realisticidealisticindividualisticpessimistic Read the passages:Passage A Minerals, water, air, organic matter, and organisms make up the material we call soil. This material covers the Earth's surface and supports life. Without soil, plants would not grow, and animals would not survive.Even though speaking about soil seems simple enough, it is actually very complex. That is because soil comes in many different forms which are made of layers, called horizons. When you look at the horizons together, you get a soil profile. Each horizon has its own set of characteristics. Some soil characteristics are the amount of sand, the type of minerals, and the amount of decomposing leaves found in the soil. All of these characteristics will help determine what kind of plant life the soil can support.Passage B Healthy plants are plants that are able to take sunlight, water, and nutrients and turn them into food. Their roots absorb two of these ingredients from the soil around them. The ideal soil for growing is one that contains the right amount of water without being too wet. It also contains many nutrients.How do nutrients make it into the soil? The answer is actually quite complex. Nutrient-rich soil contains organic matter, which is broken-down plant and animal matter. As the plant and animal matter decays, or decomposes, it releases nutrients into the soil. Then, it is absorbed by living plants and turned into food. Therefore, the richer the nutrients in the soil, the healthier the plant.Based on the information in Passages A and B, how do the nutrients in the soil determine what kind of plant it can support? In order to get nutrients into the soil, plants and animals decompose, which means they are broken down and absorbed as food. Plants absorb the nutrients they need from the soil to make food, so the type of nutrients in the soil need to match the type of nutrients needed by the plant. Soil horizons share their nutrients so that plants and animals have enough food to survive, especially during the summer season. The minerals, water, and organic matter in the soil keep plants from growing large, so plants need to choose a spot that doesn't have any of those things. when did the black death begin Choose the graph of this equation. y = 2.5xBRAINLIST IF RIGHT!!!!
