The answer is D. ∠FVI and ∠GVE. An obtuse angle must be wider than 90° (like the corners of a square or rectangle) and less than 180° (literally a straight line).

An obtuse angle in Mathematics is an angle that is greater than 90 degrees but less than 180 degrees. To identify obtuse angles in a figure, you measure the angles with a protractor. An example of an obtuse angle is one that measures 95 degrees.

In the field of Mathematics, specifically geometry, an obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees. To determine which angles in your figure are obtuse, you would need to measure them. You typically do this with a protractor. If the angle measures more than 90 degrees, it is obtuse. For example, if an angle measures 95 degrees, it is considered obtuse. However, providing specifics without an actual figure to reference is difficult.

Answer:

1  x=-2.5  y = -5.5

2.  x=5  y=1

Step-by-step explanation:

1) What is the solution of the given system?

5x-y=-7

3x-y=-2

Multiply the second equation by -1

-1*(3x-y)=-1(-2)

-3x +y = 2

Now add the first equation to the modified second equation

5x-y=-7

-3x +y = 2

------------------

2x = -5

Divide each side by 2

2x/2 = -5/2

x = -2.5

Now we need to find y

-3x+y =2

-3(-2.5) +y =2

7.5 +y =2

Subtract 7.5 from each side

7.5 -7.5 +y =2-7.5

y = -5.5

2) what is the solution of the given system?

5x+7y=32

8x+6y=46

Divide the second equation by 2

8x/2+6y/2=46/2

4x+3y =23

Multiply the first equation by 4

4 (5x+7y)=32*4

20x+28y = 128

Now multiply the modified 2nd equation by -5

-5(4x+3y )=-5(23 )

-20x -15y = -115

Lets add the new equations together to eliminate x

20x+28y = 128

-20x -15y = -115

---------------------

      13y = 13

Divide each side by 13

13y/13 =13/13

y=1

Now substitute back in to find x

5x+7y=32

5x +7(1) =32

5x +7 =32

Subtract 7 from each side

5x+7-7 =32-7

5x =25

Divide by 5

5x/5 =25/5

x=5

Answer: 180, 185, & 190

Step-by-step explanation:

1st #: 5x

2nd #: 5(x + 1)

3rd #: 5(x + 2)

1st # + 2nd # + 3rd # = sum

5x + 5(x + 1) + 5(x + 2) = 555

Answer: $31.99

Step-by-step explanation:

So, it is originally $39.99, so first we convert 20% to a decimal, which is 0.2.

Then we do 39.99 * 0.2 to find how much money was taken off.

39.99 * 0.2 = 7.998, or $8

Now, we do the original dollar amount, $39.99, minus the discount, $8, which equals $31.99.

Answer:

8(5x + 3y -7)

Step-by-step explanation:

A common number in 40x+24y-56 is 8.

40x / 8 = 5x

24y / 8 = 3y

-56 / 8 = -7

We finally get 8 (5x + 3y -7)

Hope this helps!

-sruthi123

Answer:

8 (5x +3y -7)

Step-by-step explanation:

40x+24y-56

40x = 8*5*x = 2*2*2 *5*x

24y = 3*8*y = 3*2*2*2*y

56 = 7*8 = 7 * 2*2*2

As we can see, each of these terms has a greatest common factor of 8, so we can factor it out

8 (5x +3y -7)

Answer:

Numbers are divisible by 9 if the sum of all the individual digits is evenly divisible by 9

Step-by-step explanation:

5+3+6+4 = 18

18 is divisible by 9 so therefore, those numbers are monomials of the number 9.

Monomials that are divisible by 9 are those whose numeric coefficient is divisible by 9. For example, the monomial 27x or 81y^2 are both divisible by 9 because their numeric coefficients (27 and 81, respectively) are divisible by 9.

In mathematics, a monomial is an algebraic expression consisting of one term. Monomials that are divisible by 9 are those whose numeric coefficient is divisible by 9. For example, if you have a monomial like 27x, you can check if it's divisible by 9 by dividing the numeric coefficient (27) by 9. Since 27 divided by 9 is equal to 3, you can conclude that 27x is divisible by 9. Another example would be 81y^2 where the numeric coefficient is 81. Because 81 divided by 9 equal to 9, 81y^2 is also divisible by 9. So any monomial with a numeric coefficient that is a multiple of 9 is divisible by 9.

(a) Company D has the least variability because it has the smallest range.

(b) Company A has the highest salaries, on average, because it has the largest mean salary.

(a) The company with the least variability in salaries is Company A, with a coefficient of variation of approximately 234.62.

(b) The company with the highest average salary is Company A, with a mean salary of $26,000.

(a) Variability of Salaries:

Variability in this context refers to how spread out the salaries are within each company.

Company A has a mean salary of $26,000 and a range of $61,000. Company B has a mean salary of $23,000 and a range of $66,000. Company C has a mean salary of $24,000 and a range of $69,000. Company D has a mean salary of $25,000 and a range of $60,000.

Calculating the coefficient of variation (CV) for each company will provide a clearer picture of the relative variability. The CV is obtained by dividing the standard deviation by the mean and multiplying by 100. Since the standard deviation is not given directly, we can infer that the coefficient of variation will be highest for the company with the largest range.

The CV for each company is as follows:

CV for Company A = (Range of Salaries / Mean Salary) * 100 = (61000 / 26000) * 100 ≈ 234.62

CV for Company B = (66000 / 23000) * 100 ≈ 286.96

CV for Company C = (69000 / 24000) * 100 ≈ 287.50

CV for Company D = (60000 / 25000) * 100 = 240.00

(b) Highest Average Salaries:

To identify the company with the highest average salary, we compare the mean salaries of each company.

Company A: Mean Salary = $26,000

Company B: Mean Salary = $23,000

Company C: Mean Salary = $24,000

Company D: Mean Salary = $25,000

Answer:

The range of the number of people that are satisfied is option A. 46,968 to 51,912 customers.

Step-by-step explanation:

Hi, to solve this problem you need to calculate the total number of customers that are pleased with the service, based on the 150 people sample.

so:

(72,000 x 103 )÷150 = 49,440

The next step is to calculate the 5% margin of error of that result.

49,440 x 0.05= 2,472

Finally, to obtain the range you need to add and subtract the margin to the total number of customers that are pleased with the service.

49,440-2,472= 46,968

49,440 + 2,472=51,912

So, the range of the number of people that are satisfied is option A. 46,968 to 51,912 customers.

Step-by-step explanation:

Step 1: The y-intercept is on the y-axis line. The y-intercept in this graph is -2.

Step 2: To find the slope. The line is going downwards so that helps us know that the slope is going to be negative. You want to get the bottom point to the top. So move upwards 1 time and move 4 times to the left.

Step 3: Now just put everything together.

Answer:

B. y = 4 +  6x

Step-by-step explanation:

We know that the rate of change of a straight line is equal to the slope of the line.

Now, the general form of a straight line is y = mx + b, where m is the slope and b is the y-intercept.

Also, the slope of a line joined by [tex]( x_{1},y_{1} )[/tex] and [tex]( x_{2},y_{2} )[/tex] is given by [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex].

So, using these, we will find the slopes of the lines given in the options.

A. Here, we are given two points (3,3) and (4,6). Then, the slope is given by,

[tex]m_{1}=\frac{6-3}{4-3}[/tex] i.e. [tex]m_{1}=3[/tex].

B. We have the equation of line y = 4 + 6x. On comparing it with the general form, we get that the slope is 6 i.e. [tex]m_{2}=6[/tex].

C. We are given the standard form of a line. First, we convert it into the slope-intercept form ( or the general form ).

i.e. 12x + 6y = 18 → 2x + y = 3 → y = -2x + 3

Now, on comparing this equation with the general form of a line, we get that the slope is -2. i.e. [tex]m_{3}=-2[/tex].

D. Here, we are given a linear function passing through (1,-1) and (0,4). Then the slope is given by,

[tex]m_{1}=\frac{4+1}{0-1}[/tex] i.e. [tex]m_{4}=-5[/tex].

Hence, we obtain that the function y=4+6x has the greatest slope or the greatest rate of change i.e. [tex]m_{2}=6[/tex].

To model the population increase, use the formula P = P0 * (1 + r)^t, where P is the final population, P0 is the initial population, r is the annual growth rate, and t is the number of years. The population after 15 years can be found by substituting t = 15 into the function.

To model the population increase, we can use the formula for exponential growth.

The formula is P = P0 * (1 + r)^t, where P is the final population, P0 is the initial population, r is the annual growth rate (as a decimal), and t is the number of years.

In this case, the initial population is 1,500 and the annual growth rate is 15%. So the exponential function to model the population increase is P = 1500 * (1 + 0.15)^t.

To find the population after 15 years, we can substitute t = 15 into the function. P = 1500 * (1 + 0.15)^15

Answer:

The helicopter still needs to fly up sec 17.0886 at maximum speed.

Step-by-step explanation:

To find out how many times greater 6 x 10^-5 is than 5 x 10^-9, you divide the first number by the second number. The result, in standard form, is 12,000,000 or 1.2 x 10^7. Thus, 6 x 10^-5 is 12,000,000 times greater than 5 x 10^-9.

The question is asking us to determine how many times greater 6 x 10^-5 is than 5 x 10^-9. To do this, we need to divide the first number (6 x 10^-5) by the second number (5 x 10^-9).

First, let's express these numbers in standard form. 6 x 10^-5 equals 0.00006 and 5 x 10^-9 equals 0.000000005.

Simply divide 0.00006 by 0.000000005. The result is 12,000,000 or 1.2 x 10^7.

Therefore, 6 x 10^-5 is 12,000,000 times greater than 5 x 10^-9 or 1.2 x 10^7 times greater.
