To find the measure of angle G in triangle FGH, we can use the fact that the sum of angles in a triangle is always 180 degrees.

First, we can find the measure of angle H using the fact that the sum of angles in a triangle is 180 degrees:

H = 180 - F - G

H = 180 - 72 - G

H = 108 - G

Next, we can use the Law of Cosines to find the length of side FG:

FG^2 = GH^2 + FH^2 - 2(GH)(FH)cos(F)

FG^2 = 8^2 + 13^2 - 2(8)(13)cos(72)

FG^2 = 169.21

FG ≈ 13.01 ft

Finally, we can use the Law of Cosines again to find the measure of angle G:

cos(G) = (FG^2 + GH^2 - FH^2) / (2(FG)(GH))

cos(G) = (169.21 + 64 - 169) / (2(8)(13))

cos(G) = 0.7686

G ≈ 40.6 degrees

Therefore, the measure of angle G in triangle FGH is approximately 40.6 degrees.

Find the slope (rise over run) and the y intercept for each function.

Answer: The total number of tickets sold (student and adult) cannot exceed 110, so we can write the first inequality as:

r + y ≤ 110

The minimum amount of money needed from ticket sales is $720, so we can write the second inequality as:

4r + 9y ≥ 720

To graph the system of inequalities, we can start by plotting the two lines corresponding to r + y = 110 and 4r + 9y = 720. The solution to the system of inequalities is the area on the graph that is shared by both of the inequalities (i.e., the area above the line 4r + 9y = 720 and below the line r + y = 110).

One possible solution for the number of student tickets (r) and adult tickets (y) is (30, 80). This means that 30 student tickets and 80 adult tickets can be sold to meet the conditions and raise at least $720.

A prime factor is any semi natural integer that is able to divided only by itself and by 1. Actually, a few of the initial number theory are 2, 3, 5, 7, 11, and so forth. a sum that has multiplied to yield a new sum.

Answer:

  the required equation is x² -10x +18 = 0

Step-by-step explanation:

Given side x and diagonal 8 cm of a rectangle with perimeter 20 cm, you want to show that the value of x satisfies an equation of the form ...

  x² +ax +b = 0 . . . . . where a and b are integers.

The perimeter is the sum of the side lengths. It can be expressed by the formula ...

  P = 2(L +W)

Solving for W gives ...

  W = P/2 -L

For the given rectangle, the width is ...

  W = 20/2 -x = 10 -x

The length of the diagonal is related to the length and width of the rectangle by the Pythagorean theorem.

  c² = a² +b²

  8² = x² +(10 -x)² = 2x² -20x +100

  32 = x² -10x +50 . . . . . . . . divide by 2

  x² -10x +18 = 0 . . . . . . . . . . subtract 32

This shows that x must satisfy a quadratic of the form x² +ax +b = 0, where a=-10, and b=18, both integers.

The percentage Tallulah have to put down in order to pay for the car is given by the equation A = 15 %

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Let the percentage Tallulah have to put down in order to pay be A

Now , the equation will be

The price of the car = $ 18,500

The amount of money Tallulah can get from the bank = $ 15,725

So , the remaining amount = price of the car - amount of money Tallulah can get from the bank

Substituting the values in the equation , we get

The remaining amount = 18,500 - 15,725

The remaining amount = $ 2,775

Now , $ 2,775 = A % of price of the car

So , 2,775 = ( A/100 ) x 18,500

On simplifying the equation , we get

Divide by 18,500 on both sides of the equation , we get

A/100 = 0.15

Multiply by 100 on both sides of the equation , we get

A = 15 %

Hence , the percentage is 15 %

because 0.25 = 1/4.

so, it is actually

82.5 + 8×(1/4)x = 338.5

which is then simplified

82.5 + (8/4)x = 338.5

82.5 + 2x = 338.5

Step-by-step explanation:

[tex]\displaystyle\\8(0.25x)=8(\frac{25}{10}x)=\frac{8*25}{100} x=\frac{200}{100}x=2x[/tex]

Thus, 82.5+8(0.25x)=338.5  ≡  82.5+2x=338.5

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(1) = 2

f(2) = 1

f(n) = f(n - 1) + f(n - 2)

Now,

For n = 3,

f(3) = f(3 - 1) + f(3 - 2) = f(2) + f(1) = 1 + 2 = 3

f(4) = f(4 - 1) + f(4 - 2) = f(3) + f(2) = 3 + 1 = 4

f(5) = f(5 - 1) + f(5 - 2) = f(4) + f(3) = 4 + 3 = 7

We see that,

The next sequence is the addition of the previous two sequences.

Answer: The first term of the sequence is 2, and the second is 1. The function adds the previous two terms to get the next term.

To get the first six terms of the sequence, start by finding the third term by substituting the values of the first two terms in the function:

f(3) = f(2) + f(1) = 1 + 2 = 3.

In the same way, find the remaining three terms and get the sequence as (2, 1, 3, 4, 7, 11, . . .).

To find the 12th term of the sequence, continue using the rule to find all terms until the 12th. So, the sequence is (2, 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199, . . .).

A calibration curve is a graphical representation of the relationship between the output of a measuring instrument and the actual values of the quantity being measured.

What is the calibration curve?

A calibration curve is typically created by measuring a set of known values of the quantity being measured, and plotting the measured values against the actual values. The curve is used to make adjustments to the measurements obtained with the instrument, so that they more accurately reflect the actual values of the quantity being measured.

A calibration curve can be described as a plot of the relationship between the output of a measuring instrument and the actual values of the quantity being measured. The curve is typically linear, and the slope of the curve represents the sensitivity of the instrument. The y-intercept of the curve represents the offset or bias of the instrument, and any deviations from a straight line represent non-linearity in the measurement.

Answer: 44%

Step-by-step explanation:

100 - 49 - 7 = 44 people who preferred Soda B

44 of a 100 = 44%

Answer: 44%

Step-by-step explanation:

Since we have 100 people, each person is one percent.

49 people preferred A, so we can subtract 49 from 100.

100 - 49 = 51

7 people didn't have an opinion, so we can subtract 7 from 51.

51 - 7 = 44

That means that 44 people preferred B, which is 44%

Answer: 6x=90

Step-by-step explanation:

We know that one angle in a right triangle is 90 degrees and the sum of all the angles is 180, so we can start by subtracting 90 from 180. We are left with 90 and now we have angle ratios which represent fractional quantities. We know that one of these quantities is 5 and the other is 1. Their sum is 6 and equals 90. So the proportion would be 6x = 90. The larger angle is 75 degrees and the smaller one is 15.

Range = 7. IQR = 4.5. Variance: 8.67, Std Dev: 2.96 when researcher organized diet groups on weight loss weighed five clients after several weeks on the program.

The range of the weight-loss scores can be calculated by subtracting the smallest value from the largest value. In this case, the range would be

13 - 6 = 7.

The inter-quartile range (IQR) is calculated as the difference between the 75th percentile and the 25th percentile of the data.

IQR: 11.25 - 6.75 = 4.5

To calculate the variance, first find the mean weight-loss score by summing all the scores and dividing by the number of clients: (13 + 12 + 6 + 9 + 9 + 10) / 6 = 9.17. Next, subtract the mean from each score and square the result for each client:

[tex](13 - 9.17)^2 = 3.69\\(12 - 9.17)^2 = 1.69\\(6 - 9.17)^2 = 16.0\\(9 - 9.17)^2 = 0.02\\(9 - 9.17)^2 = 0.02\\(10 - 9.17)^2 = 0.69[/tex]

Next, sum the squared deviations and divide by the number of clients minus one (n-1):

(3.69 + 1.69 + 16.0 + 0.02 + 0.02 + 0.69) / (6-1) = 4.83

The variance is 4.83 and the standard deviation is the square root of the variance: [tex]\sqrt{(4.83)} = 2.19.[/tex]

The approximate area between the x-axis and the function, f(x) = x² + 3, obtained by finding the sum of the of the four rectangles is Area ≈ 9.75

The area between the x-axis and the graph under a function can be referred to as the area under a curve of the function, which can be found using definite integrals.

The area between the x-axis and the function f(x) = x² + 3 over the interval [0, 2], can be found by finding the area of the rectangular bars, A, in the figure as follows;

The values at the endpoints of the rectangles are; 0.5, 1, 1.5, and 2

Therefore;

f(0.5) = 0.5² + 3 = 3.25

f(1) = 1² + 3 = 4

f(1.5) = 1.5² + 3 = 5.25

f(2) = 2² + 3 = 7

Therefore; A = 0.5 × f(0.5) + 0.5 × f(1) + 0.5 × f(1.5) + 0.5 × f(2)

Plugging in the values of the function, we get;

Area ≈ 0.5 × 3.25 + 0.5 × 4 + 0.5  × 5.25 + 0.5 × 7 = 9.75
