Answers

Answer 1

Answer:

The answer to your question is:

a) ∠FGH = 34°

b) ∠HGI = 34°

c) ∠FGI = 68°

Step-by-step explanation:

We know that GH bisects ∠FGI

a) Find ∠FGH

∠ FGH = 5x - 6

∠ HGI = 6x -14

                      ∠ FGH = ∠ HGI

                     5x - 6   =  6x - 14

                    5x - 6x = -14 + 6

                          -1x = - 8

                            x = 8

∠ FGH = 5(8) - 6

            = 40 - 6

            = 34°          

b) m∠HGI = 6(8) -14

                = 48 - 14

                =  34°          

c) m∠FHI =  ∠ FGH + ∠ HGI

                = 34 + 34

               = 68°

Vector A⃗ has magnitude 5.00 and is at an angle of 36.9∘ south of east. Vector B⃗ has magnitude 6.40 and is at an angle of 20.0∘ west of north. Choose the positive x-direction to the east and the positive y-direction to the north. Find the components of A⃗ .

Answers

Final answer:

The x-component of vector A is 4.00 units east, and the y-component of vector A is -3.00 units south, calculated using the cosine and sine functions respectively.

Explanation:

The student has asked for the components of vector A which has a magnitude of 5.00 units and is at an angle of 36.9° south of east. To find the components of a vector, we use trigonometric functions. The component along the x-axis (east-west direction) is found using the cosine function, and the component along the y-axis (north-south direction) is found using the sine function. Since the angle is south of east, the x-component will be positive and the y-component will be negative in our coordinate system.

The x-component of vector A (Ax) is calculated as:

Ax = A * cos(θ) = 5.00 * cos(36.9°) = 5.00 * 0.800 = 4.00 units

The y-component of vector A (Ay) is calculated as:

Ay = A * sin(θ) = 5.00 * sin(36.9°) = 5.00 * 0.600 = 3.00 units

Therefore, the components of vector A are 4.00 units east and -3.00 units south.

Eight hundred tickets were sold for a movie production and the receipts for the performance wear $8600. The tickets for adults and students sold for $12.50 and $7.50, respectively. How many of each ticket were sold?

Answers

Answer:

280 student tickets520 adult tickets

Step-by-step explanation:

You may recognize that you are given two relationships between two unknowns. You can write equations for that.

You are asked for numbers of adult tickets and of student tickets. It often works well to let the values you're asked for be represented by variables. We can choose "a" for the number of adult tickets, and "s" for the number of student tickets. Then the problem statement tells us the relationships ...

  a + s = 800 . . . . . . 800 tickets were sold

  12.50a + 7.50s = 8600 . . . . . . . revenue from sales was 8600

(You are supposed to know that the revenue from selling "a" adult tickets is found by multiplying the ticket price by the number of tickets: 12.50a.)

___

You can solve these two equations any number of ways. One way is to do it by elimination. We can multiply the first equation by 12.50 and subtract the second equation:

  12.50(a +s) -(12.50a +7.50s) = 12.50(800) -(8600)

  5s = 1400 . . . . simplify. (The "a" variable has been eliminated.)

  s = 280 . . . . . . divide by 5

Then the number of adult tickets can be found from the first equation:

  a + 280 = 800

  a = 520

280 student tickets and 520 adult tickets were sold.

520 adult tickets and 280 student tickets were sold.

To solve this problem, we need to set up a system of two linear equations using the given information and then solve for the number of adult and student tickets sold.

Let x be the number of adult tickets sold, and y be the number of student tickets sold.

Given information:

- Total number of tickets sold: [tex]x + y = 800[/tex]

- Total receipts: [tex]12.50x + 7.50y = 8600[/tex]

We have a system of two equations with two unknowns:

[tex]x + y = 800[/tex]

[tex]12.50x + 7.50y = 8600[/tex]

We can solve this system using the substitution method or the elimination method.

Using the substitution method:

From the first equation, [tex]y = 800 - x[/tex]

Substituting this into the second equation:

[tex]12.50x + 7.50(800 - x) = 8600[/tex]

[tex]12.50x + 6000 - 7.50x = 8600[/tex]

[tex]5x = 2600[/tex]

[tex]x = 520[/tex]

Substituting [tex]x = 520[/tex] into the first equation:

[tex]y = 800 - 520 = 280[/tex]

Therefore, 520 adult tickets and 280 student tickets were sold.

By setting up a system of linear equations based on the given information and solving them using algebraic methods, we can find the number of adult and student tickets sold that satisfy the conditions of the total number of tickets and the total receipts.

Consider this bag of marbles. What is the probability of drawing a green marble versus the ODDs of drawing a green marble? What is the difference in these two things? Make sure you show work, answer all questions, and write in complete sentences.

Answers

Answer:

Probability: 50%

odds: 5:5

Step-by-step explanation:

Answer:

The probability is 50% that ball will be green.

Odds 5:5

Numbers of ways to draw a green marbles: number of ways to draw another marbles.

Step-by-step explanation:

Consider the provided bag of marble.

The bag contains 5 green marble, 3 blue marbles and 2 red marbles.

The total number of marbles are: 5+3+2=10

The probability of getting a green marble is: 5/10=0.5

That means the probability is 50% that ball will be green.

Drawing green marbles means we want marble should be green and ODDs of drawing a green marble means the marble is not green.

There are 5 green marbles, so there are 5 outcomes that we want (out of 10 outcomes total)

There are 10-5 = 5 outcomes that we don't want a green marble.

Number of outcomes we want is 5

Number of outcomes we don't want is 5

Odds in favor = (wanted outcomes):(unwanted outcomes)

Odds in favor = 5:5

Numbers of ways to draw a green marbles: number of ways to draw another marbles.

By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).

Answers

Answer:

23

Step-by-step explanation:

or 2.8 but try 23 frist

The percentage of increase of total number of students on the honor roll is obtained as 22.97%.

What is percentage?

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

And to convert a fraction or a decimal into percentage, they are multiplied by 100.

The number of boys and girls on the honor code last year is given as 132 and 90.

Then, the total number is 132 + 90 = 222.

When, the number of boys increased by 25%, it can be obtained as,

⇒ 132 + 25% × 132 = 165

And, the number of girls increased by 20% can be obtained as,

⇒ 90 + 20% × 90 = 108

Now, the total number of students is 165 + 108 = 273.

The percent increase can be obtained as follows,

Change in the total number ÷ Initial number × 100

⇒ (273 - 222) ÷ 222 × 100 = 22.97%

Hence, the percent value of the increase in the number is 22.97%.

The functions are inverses; f(g(x)) = x ⇒ answer D

[tex]h^{-1}(x)=\sqrt{\frac{x+1}{3}}[/tex] ⇒ answer D

Step-by-step explanation:

* Lets explain how to find the inverse of a function

- Let f(x) = y

- Exchange x and y

- Solve to find the new y

- The new y = [tex]f^{-1}(x)[/tex]

* Lets use these steps to solve the problems

∵ [tex]f(x)=\sqrt{x-3}[/tex]

∵ f(x) = y

∴ [tex]y=\sqrt{x-3}[/tex]

- Exchange x and y

∴ [tex]x=\sqrt{y-3}[/tex]

- Square the two sides

∴ x² = y - 3

- Add 3 to both sides

∴ x² + 3 = y

- Change y by [tex]f^{-1}(x)[/tex]

∴ [tex]f^{-1}(x)=x^{2}+3[/tex]

∵ g(x) = x² + 3

∴ [tex]f^{-1}(x)=g(x)[/tex]

The functions are inverses to each other

* Now lets find f(g(x))

- To find f(g(x)) substitute x in f(x) by g(x)

∵ [tex]f(x)=\sqrt{x-3}[/tex]

∵ g(x) = x² + 3

∴ [tex]f(g(x))=\sqrt{(x^{2}+3)-3}=\sqrt{x^{2}+3-3}=\sqrt{x^{2}}=x[/tex]

f(g(x)) = x

The functions are inverses; f(g(x)) = x

* Lets find the inverse of h(x)

∵ h(x) = 3x² - 1 where x ≥ 0

- Let h(x) = y

∴ y = 3x² - 1

- Exchange x and y

∴ x = 3y² - 1

- Add 1 to both sides

∴ x + 1 = 3y²

- Divide both sides by 3

∴ [tex]\frac{x + 1}{3}=y^{2}[/tex]

- Take √ for both sides

∴ ± [tex]\sqrt{\frac{x+1}{3}}=y[/tex]

∵ x ≥ 0

∴ We will chose the positive value of the square root

∴ [tex]\sqrt{\frac{x+1}{3}}=y[/tex]

- replace y by [tex]h^{-1}(x)[/tex]

∴ [tex]h^{-1}(x)=\sqrt{\frac{x+1}{3}}[/tex]

in 1998:

Ks₂ - Js₂ = 2440$

now, we know that  Ks₂ = (1 +p)*Ks₁ and   Js₂ = (1+p)*Js₁

so we can write the second equation as:

p*(Ks₁ - Js₁ ) = 2440$

replacing the parentesis with the first equiation

(1+p)*(2000$) = 2440$

(1+p)= 2440/2000 = 1.22

so p = 0.22, or a 22%

So we can talk about the diagram, let's name a couple of points. The base of the tree is point T, and the top of the tree is point H. We want to find the length of TH given the length AB and the angles HAT and ABT.

The tangent function is useful here. By its definition, we know that ...

  TA/BA = tan(∠ABT)

and

  TH/TA = tan(∠HAT)

Then we can solve for TH by substituting for TA. From the first equation, ...

  TA = BA·tan(∠ABT)

From the second equation, ...

  TH = TA·tan(∠HAT) = (BA·tan(∠ABT))·tan(∠HAT)

Filling in the values, we get ...

There are 2 mixtures of light purple paint.
Mixture A is made with 5 cups of purple paint and 2 cups of white paint.
- Mixture B is made with 15 cups of purple paint and 8 cups of white paint.
Which mixture is a lighter shade of purple? Explain your reasoning.​

Answers

Answer:

mixture a because there's not so much purple.the more purple the darker it is

Answer:

The mixture B is a lighter shade of purple.

Step-by-step explanation:

In order to answer the question, we first need to calculate the proportion of purple in both mixtures. The mixture that has the lowest proportion of purple will be the lighter one.

For mixture A :

5 cups of purple

2 cups of white paint

⇒ Mixture A is made with 5 + 2 = 7 cups of paint in which 5 are cups of purple. Therefore, we can calculate the proportion of purple as :

[tex]\frac{5CupsOfPurple}{7CupsInTheMixture}=\frac{5}{7}=0.7143[/tex]

This means that approximately 71.43% of the mixture A is made of purple paint.

For mixture B :

15 cups of purple paint

8 cups of white paint

⇒ Mixture B is made with 15 + 8 = 23 cups of paint in which 15 are cups of purple. Therefore, we can calculate the proportion of purple as :

[tex]\frac{15CupsOfPurple}{23CupsInTheMixture}=\frac{15}{23}=0.6522[/tex]

This means that approximately 65.22% of the mixture B is made of purple paint.

If we compare the proportions :

[tex]0.7143>0.6522[/tex] ⇒ [tex]Proportion_{A}>Proportion_{B}[/tex]

We conclude that the mixture B is a lighter shade of purple because it has the lowest proportion of purple (we can also think that mixture B has the highest proportion of white)

Find the diagonal MN of the prism MEZAFUN

Answers

Answer:

MN = sqrt(34)

Step-by-step explanation:

First, draw the segment FN. The diagonal, MN, of the prism is the hypotenuse of triangle NFM. Triangle NFM is a right triangle with legs FN and FM and hypotenuse MN.

Leg FM of triangle NFM has length 4 cm.

We need to find the length of leg FN.

Look at the base of the prism which is square UNAF. FN is a diagonal of that square. Now think of right triangle FUN with legs UN and UF, each of length 3 cm. We can find FN with the Pythagorean theorem.

(UF)^2 + (UN)^2 = (FN)^2

3^2 + 3^2 = (FN)^2

(FN)^2 = 18

FN = sqrt(18)

Now we know FN. We use FN and FM as legs and find MN, the hypotenuse of triangle NFM.

(FN)^2 + (FM)^2 = (MN)^2

18 + 4^2 = (MN)^2

18 + 16 = (MN)^2

(MN)^2 = 34

MN = sqrt(34)

Fill in the table so it represents a linear function.

Answers

Answer:

-1, 2, 5, 8, 11

Step-by-step explanation:

There is an easy and fast way to solve this. A linear function means that the steps on y and x are constant.

On the x axis you are walking 5 steps each column, so you start from 5, plus 5 steps is 10, plus 5 steps is 15, plus 5 steps is 20, plus 5 steps is 25.

Now you have to do the same for the y axis, but you have to use your brain.

You start from -1, and you have to reach 11, using the same number of steps for each column, just like before the necessarily with the same number.

You start from -1, plus 3 steps is 2, plus 3 steps is 5, plus 3 steps is 8, plus 3 steps is 11. Done.

You can use maths also, but it will take time.

You need to find that function. A linear function can be written as:

[tex]y = mx + q[/tex]

You have two points of the line, (5, -1) and (25, 11), but you need to find the y coordinate of other three points.

Let's find the line by substituting those points in the general function of the line:

[tex] - 1 = 5m + q \\ 11 = 25m + q[/tex]

This is a system of two equations with two variables, m and q. You can solve it. From the first equation you have that:

[tex]q = - 1 - 5m[/tex]

Put this in the second equation to know the value of m:

[tex]11 = 25m + ( - 1 - 5m)[/tex]

[tex]11 = 25m - 1 - 5m \\ 20m = 12 \\ m = \frac{12}{20} = \frac{3}{5} [/tex]

Now you can use this in the first equation to know the value of q:

[tex]q = - 1 - 5( \frac{3}{5} ) \\ q = - 1 - 3 \\ q = - 4[/tex]

So your line is:

[tex]y = \frac{3}{5} x - 4[/tex]

If you want to know the y coordinates that you are missing, you just need to put the corresponding x coordinate in this function and you will find the same results as before.

Final answer:

To fill in a table for a linear function, you need to understand the relationship between x and y in a linear function (y = mx + b), calculate y values for given x values using this relationship, and arrange these pairs in the table.

Explanation:

To fill in a table that represents a linear function, we need to understand that in a linear function, the change in the output (y) is constant for every unit change in the input (x). The relationship between x and y can be written as y = mx + b, where m is the slope and b is the y-intercept.

Here's a simple example. For a linear function y = 2x + 1, if your x values are 1, 2, and 3, the y values would be y(1) = 2*1+1 = 3, y(2) = 2*2+1 = 5, y(3) = 2*3+1 = 7. So the table would look like:

Jack has 63 pennies, dimes, and quarters worth $6.30. If the number of dimes is three less than the number of quarters, how many of each coin does he have? Three variable application

Answers

Answer:

18 quarters

30 pennies

15 dimes

Step-by-step explanation:

Let number of quarters be q, number of pennies be p, number of dimes be d

The value of pennies is 0.01, the value of quarters is 0.25 and value of dimes is 0.10.

Jack has 63 pennies, dimes, and quarters worth $6.30:

We can write:

p + q + d = 63

0.01p + 0.25q + 0.10d = 6.30

Also, the number of dimes is three less than the number of quarters:

We can write:

d = q - 3

Now we have written 3 equations. Replacing 3rd equation in 1st gives us:

p + q + (q-3) = 63

p + 2q -3 = 63

p + 2q = 66

Solving for p:

p = 66 - 2q

Now we can use this and the 3rd equation and replace p and d with q:

0.01p + 0.25q + 0.10d = 6.30

0.01(66-2q) + 0.25q + 0.10(q-3) = 6.30

Solving for q, gives us:

[tex]0.01(66-2q) + 0.25q + 0.10(q-3) = 6.30\\0.66-0.02q+0.25q+0.10q-0.3=6.30\\0.36+0.33q=6.30\\0.33q=5.94\\q=18[/tex]

There are 18 quarters

Since, p = 66 - 2q, there are:

p = 66 - 2 (18) = 30 pennies

Also,

d = q - 3, so d = 18 - 3 = 15 dimes

Hence, there are:

18 quarters

30 pennies

15 dimes

The answer to your question is: 4.2 x 10⁻²

Step-by-step explanation:

Information: (3 x 10⁶) x (1.4 x 10⁻⁸)

                    3 x 1.4 = 4.2                                   we just multiply the integers

                   10⁶ + 10⁻⁸ = -2                                then we add 6 and -8

                   4.2 x 10⁻²                                   now join the results and -2 will be a power of ten.

which equation is the equation of the line, in point-slope form, that has a slope of 1.9 and passes through the point (4.5, -1.4) ?

Answers

Answer:

y+1.4=1.9 (x-4.5)

Step-by-step explanation:

The slope is the number in front of the brackets, which must be positive 1.9. This eliminates the last option. It is y+1.4 because the formula is y-y1=m (x-x1)

So once you substitute values

y--4.5=1.9 (x-4.5)

y+4.5=1.9 (x-4.5)

An equation of the line in point-slope form is: B. y + 1.4 = 1.9(x - 4.5)

How to determine an equation of this line?

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

x and y represent the data points.m represent the slope.

At data point (4.5, -1.4) and a slope of 1.9, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - (-1.4) = 1.9(x - 4.5)  

y + 1.4 = 1.9(x - 4.5)

Help PLease. A vector is defined as having magnitude of 15 m and a direction of East. Multiply this vector by the scalar value of –6. What is the resultant vector’s magnitude and direction?




What are the components of a vector C→ if its magnitude is 8.9 m/s and it makes an angle of –40° with the +x-axis?

Answers

Answer:

90 m West(6.82, -5.72) m/s

Step-by-step explanation:

1. The magnitude of the multiplier is 6, so the magnitude of the new vector is 6×(15 m) = 90 m. The sign on the multiplier is negative, so the new vector will be in the opposite direction of East. It will be 90 m West.

__

2. The components can be found from ...

  (8.9 m/s)(cos(-40°), sin(-40°)) ≈ (6.82, -5.72) m/s

A class of fourth graders takes a diagnostic reading test and the scores are reported by reading level. The 5-number summaries for the 14 boys and 11 girls are shown:

Boys: 2.0, 3.9, 4.3, 4.9, 6.0
Girls: 2.8, 3.8, 4.5, 5.2, 5.9

Which group generally did better on the test?

Answers

Answer:

The girls had a higher average in the reading test than the boys.

Step-by-step explanation:

To find the solution, you need to find the mean (average) of the group of boys and group of girls each. The mean of numbers can be found by dividing the sum of all numbers by the amount of numbers there are.

Lets start by finding the mean of the boys group. Find the sum of all numbers:

[tex]2.0 + 3.9 + 4.3 + 4.9 + 6.0 = 21.1[/tex]

Now divide the sum by how many numbers, or in this case, how many boys did the test:

[tex]21.1 \div 5 = 4.22[/tex]

The mean, average, of the tests conducted by the group of boys is 4.22.

Repeat the same for the girls group:

[tex]2.8 + 3.8 + 4.5 + 5.2 + 5.9 = 22.2 \\ 22.2 \div 5 = 4.44[/tex]

The mean, average, of the tests conducted by the group of girls is 4.44.

Compared to 4.22, 4.44 is bigger than 4.22.

A storm dumps 1.0 cm of rain on a city 6 km wide and 8 km long in a 2-h period. How many metric tons (1 metric ton = 103 kg) of water fell on the city? (1 cm3 of water has a mass of 1 g = 10−3 kg.) How many gallons of water was this?

Answers

Answer:

4660194 metric ton

126802560 gallon

Step-by-step explanation:

1 cm = 0.01 m

6 km = 6000 m

8 km = 8000 m

Volume = 0.01 m x 6000 m x 8000 m =  480000 m³

480000 m³ = 480000000 kg of water (density of water = 1000kg/m³)

103 kg = 1 metric ton

480000000 kg = 480000000 / 103 = 4660194 metric ton

1 m³ = 264.17 gallon

480000 m³ = 480000 x 264.172 = 126802560 gallon

Final answer:

A total of 480,000 metric tons of water fell on the city, which is equivalent to approximately 126,802,560 gallons of water.

Explanation:

To calculate the amount of water in metric tons that fell on the city, we need to first determine the volume of the rainfall which can be calculated by taking the product of the rainfall's depth (1.0 cm), and the area of the city (6 km x 8 km).

Firstly, convert all dimensions into the same unit. Let's use meters: 1.0 cm = 0.01 m, 6 km = 6000 m, 8 km = 8000 m. Therefore, the volume equals 0.01 m x 6000 m x 8000 m = 480,000 m³.

The mass of the water is then found by multiplying the volume by the density of water. Given that the density of water is 1 g/cm³ (or 1000 kg/m³, which is more useful here, as mass needs to be in kg), this calculation gives us a mass of 480,000,000 kg = 480,000 metric tons.

To convert this to gallons, we use the fact that 1 m³ = 264.172 gallons. Therefore, 480,000 m³ = 480,000 x 264.172 = 126,802,560 gallons.
