Answers

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]

Ms. Agokeng is making a trip to Pennsylvania that is more than 250 miles. She has already driven 45 miles and is continuing her drive at 70 miles per hour. Which of the following inequalities represents the amount of time she has left in the car?​

Answer:

The correct answer is A.) 45 + 70x < 250.

y = mx + b

She started at 45 miles (+ 45).

She has to go at least 250 miles (< 250).

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

because angle 5 is found on the same line as 45 degrees (don't remember what that's called), we can subtract from 180 to find

angle 5 = 135

angle 5 and 5x+35 are alternate interior angles, so they have the same value

-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

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%

Use VSEPR to predict the electron-pair geometry of N2.

A)

linear

B)

trigonal planar

C)

tetrahedral

D)

trigonal bipyramidal

Answers

Answer:

tetrahedral

Step-by-step explanation:

According to the valence shell electron pair repulsion theory (VSEPR) the shape of a molecule is dependent on the number of electron pairs on the valence shell of the central atom in the molecule.

The predicted electron pair geometry may sometimes differ from the molecular geometry due to the presence of lone pairs and multiple bonds.

If we consider each nitrogen atom in N2 independently, we will notice that each nitrogen atom has four regions of electron density. Hence the electron pair geometry is tetrahedral.

A bag with 6 marbles has 2 blue marbles, 1 red marble, and 3 yellow marbles. A marble is chosen from the bag at random. What is the probability that it is blue?
Write your answer as a fraction in simplest form.

Answers

Answer:

1/2

Step-by-step explanation:

We know the total amount of marbles in the bag, 6. Now, we need to make a fraction, there are 3 blue marbles, so our fraction is 3/6. This can be simplified to 1/2.

The required probability of the blue marble in the bag is 1 / 3.

Given that,
A bag with 6 marbles has 2 blue marbles, 1 red marble, and 3 yellow marbles. A marble is chosen from the bag at random, what is the probability that it is blue is to be determined.

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.

here,
Total number of marble in the bag = 6
Total number of blue marble in the bag = 2
Probability of the blue marble in the bag = 2 / 6 = 1 / 3

Thus, the required probability of the blue marble in the bag is 1 / 3.
