Tallulah wants to buy a car for \$18,500$18,500, but can only get a loan from the bank for \$15,725$15,725. What percentage does Tallulah have to put down in order to pay for the car?
The percentage Tallulah have to put down in order to pay for the car is given by the equation A = 15 %
What is Percentage?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 %

In triangle FGH, g=8ft, h=13ft, and measure of angle F=72 degree. Find measure of angle G
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.
Explain why the equation 82.5 + 8(0.25x)= 338.5 is equivalent to the equation 82.5 + 2x = 338.5
Step-by-step explanation:
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

q1 and q2 are 24m apart. if q2 is 49 times q1, where between the two charges would the net electric field be equal to 0
The point where the net electric field is equal to zero is located approximately 0.48936m away from q1 and 24m - 0.48936m = 23.51064m away from q2.
Describe charge?Charge is a fundamental property of matter that describes its electrical state. It is a scalar quantity that can be either positive, negative, or neutral, and is measured in Coulombs (C). The concept of charge is used to explain many of the phenomena that occur in electricity and magnetism, such as electric fields, currents, and voltages. Positive and negative charges are thought to be due to the presence or absence of electrons, which are the smallest negatively charged particles in matter. Neutral objects have an equal number of positive and negative charges, resulting in a net charge of zero. The interaction of charges with each other results in many of the electrical and magnetic phenomena observed in the world around us.
The net electric field at a point is equal to zero if the electric field due to one charge is exactly canceled by the electric field due to the other charge.
Since q2 is 49 times greater than q1, the electric field due to q2 will be 49 times greater than the electric field due to q1 at any given point. In order to cancel the electric field due to q1, we need to place q2 at a point that is 49 times closer to q1 than the original separation of 24m.
Let's call the new separation between the charges x. Then, x = 24m / 49, which is approximately equal to 0.48936m.
So, the point where the net electric field is equal to zero is located approximately 0.48936m away from q1 and 24m - 0.48936m = 23.51064m away from q2.

The drama club is selling tickets to their play to raise money for the show's expenses.
Each student ticket sells for $4 and each adult ticket sells for $9. The auditorium can
hold no more than 110 people. The drama club must make a minimum of $720 from
ticket sales to cover the show's costs. If r represents the number of student tickets
sold and y represents the number of adult tickets sold, write and solve a system of , a
inequalities graphically and determine one possible solution.
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 researcher interested in the effectiveness of organized diet groups on weight loss weighed five clients after several weeks on the program. The weight-loss scores (in pounds) were as follows: 13 12 6 9 9 10 Calculate the (a) range, (b) inter-quartile range, and (c) variance and standard deviation for these weight-loss scores.
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 non-right angles of a right triangle are in the ratio 1: 5, Write an equation that could be used to find the measure of each angle.
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.
Type your response in the box. Here is a function that describes a sequence called the Lucas numbers, which is similar to the Fibonacci sequence: f(n) = f(n – 1) + f(n – 2); f(1) = 2; f(2) = 1. Describe in words the relationship between the terms created by this algebraic rule. List the first six terms of the sequence. Find the 12th term.
The first six terms of the sequence are 2, 1, 3, 4, 7, and 11.
The 12th term is 199.
What is a function?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.
So,
The sequence is:
2, 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199
i.e
12th term = 199.

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, . . .).

What is the Mode, Median, Mean and range for the following $32, $87, $67, $32, $32, $87, $77 and $25
Answer:
Mean = $54.875 ($54.88 to nearest cent because $54.875 is impossible)
Median = $32
Mode = $32
Step-by-step explanation:
Mean = all numbers added together / amount of numbers in dataset
$32 + $87 + $67 + $32 + $32 + $87 + $77 + $25 = $439
$439/8= $54.875 = $54.88 to the nearest cent.
Median =
1. Order the numbers. Here's how it's ordered: $25,$32,$32,$32,$67,$77,$87
2. Calculate the middle position with the formula [tex](n+1)/2[/tex] where n is the amount of numbers in dataset (for odd datasets) or find the two middle values (for even datasets.) In this case, it is an odd dataset, so we use the formula.
(7+1)/2 = 4
In the 4th position, the number is $32, so the median is $32.
Mode = The numbers that comes up most often.
In this case, $32 comes up 4 times, which is the most, so the mode is $32.
