Answer:
$97,958.42
Step-by-step explanation:
To solve this problem we can use the compound interest formula which is shown below:
[tex]A=P(1+r )^{t}[/tex]
P = initial balance
r = interest rate
t = time
First change 6.5% to its decimal form:
6.5% -> [tex]\frac{6.5}{100}[/tex] -> 0.065
Next plug in the values:
[tex]A=49,000(1+.065)^{11}[/tex]

Answer:
The average (mean) of the test scores is
A. 76
To find the average (mean) of test scores, add them up and divide by the total number of scores. The average of these test scores is 76.
Explanation:To find the average (mean) of the test scores, you need to add up all the scores and then divide by the total number of scores. In this case, you have 5 test scores: 83, 92, 47, 78, and 80. Adding them all up, you get 83 + 92 + 47 + 78 + 80 = 380. Then, divide the sum by 5 (the total number of scores): 380 / 5 = 76. Therefore, the average of these test scores is 76.

A man has 12 coins in his pocket all of which are dimes and quarters if the total value of his change is 225 cents how many dimes and how many quarters does he have
Answer:
Quarters = 7
Dimes = 5
Step-by-step explanation:
Let d = dimes and q = quarters:
d+q = 12
10d+25q = 225
Solve for d:
d = 12-q
Substitute it into the second equation:
120+15q = 225
Subtract 120 from both sides:
15q = 105
Divide by 15 in both sides
q = 7
By setting up a system of linear equations based on the given conditions, we find that the solution involves having 9 dimes and 3 quarters. These numbers satisfy the conditions that there are 12 coins in total which combine to be worth 225 cents.
Explanation:This question is about solving a system of linear equations. Let's assign variable 'd' to the quantity of dimes and 'q' to quarters. We know from the problem that:
d + q = 12, which represents the total number of coins;10d + 25q = 225, with dimes worth 10 cents each, and quarters worth 25 cents each, their total value must be 225 cents.To solve for 'd' and 'q', we can use substitution or elimination method. In this case, let's isolate 'd' in the first equation: d = 12 - q. Then substitute 'd' into second equation: 10(12 - q) + 25q = 225. After simplifying, you will find q = 3. Subtituting q = 3 back into the first equation, we find d = 9. Thus, the man has 9 dimes and 3 quarters.

Kwan made a sculpture in the shape of a polyhedron. It only has one base that is a triangle. What three-dimensional figure is her sculpture?
Answer:
Triangular pyramid
Final answer:
Kwan's sculpture with a triangular base is a pyramid, specifically called a triangular pyramid or tetrahedron in geometry.
Explanation:
If Kwan made a sculpture in the shape of a polyhedron with only one base that is a triangle, her sculpture is a pyramid. In geometry, a pyramid is defined as a polyhedron that has a polygonal base and triangular faces that converge at a single point, called the apex. Given that Kwan's sculpture has a triangular base, her sculpture would specifically be called a triangular pyramid or tetrahedron.

Tickets to a local movie theater were sold at $6.00 for adults and $4.50 for students. There were 240 tickets sold for a total of $1155.00. Solve by elimination to find the number of adult tickets sold and the number of student tickets sold
Final answer:
To solve for the number of adult and student tickets sold, the system of equations was created from the given information and solved using the elimination method. The movie theater sold 50 adult tickets and 190 student tickets.
Explanation:
We have two equations based on the information provided about adult and student tickets sold at Family Flicks:
Adult tickets (A) at $6.00 each plus student tickets (S) at $4.50 each, total $1155.00.Let's use elimination to solve this system of equations. To do this, we must eliminate one variable. We can multiply the second equation by -4.5 to align the student ticket coefficient with the first equation:
-4.5A - 4.5S = -1080We then add this equation to the first equation:
6A + 4.5S = 1155-4.5A - 4.5S = -1080(6A - 4.5A) + (4.5S - 4.5S) = 1155 - 10801.5A = 75A = 75 / 1.5A = 50Now that we know there are 50 adult tickets sold, we can find the number of student tickets sold by substituting A into the second original equation:
A + S = 24050 + S = 240S = 240 - 50S = 190The theater sold 50 adult tickets and 190 student tickets.

Jason grew from 36 inches to 40 inches in 1 year. By percent did his growth increase? Round your answer off to the nearest tenths
The percentage increase in Jason's height is 11.1%.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.
To find the percentage increase in Jason's height, we can use the following formula:
percent increase = (final value - initial value) / initial value x 100%
In this case, the initial value is 36 inches (Jason's height at the beginning of the year) and the final value is 40 inches (Jason's height at the end of the year). Plugging these values into the formula, we get:
percent increase = (40 - 36) / 36 x 100% = 4 / 36 x 100% = 11.11%
Rounded off to the nearest tenths, the percentage increase in Jason's height is 11.1%.

Outside temperature over a day can be modelled as a sinusoidal function. Suppose you know the high temperature of 64 degrees occurs at 4 PM and the average temperature for the day is 50 degrees. Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t.
The equation for the temperature D as a function of time t in hours is given by D = 50 + 14 sin[2π/24 (t - 16)]. This equation uses a sinusoidal function to describe the fluctuation of temperature around the average of 50 degrees with an amplitude of 14 degrees.
Explanation:To model the temperature D at a given time, we use a sinusoidal function based on the high and average temperatures. We know the high temperature of 64 degrees occurs at 4 PM (which is 16 hours after midnight), and the average temperature for the day is 50 degrees. This means the amplitude of the function (or the variation above and below the average) is 14 degrees (which is 64-50).
The sinusoidal function can, therefore, be written as follows: D = 50 + 14 sin[2π/24 (t - 16)]. This function describes how, starting from the average temperature of 50 degrees, the temperature fluctuates by 14 degrees in a sinusoidal manner.

There are 4 red, 6 green, and 5 yellow pencils in a jar. Once a pencil is selected, it is not replaced. Find each probability.
This question deals with calculating probabilities of selecting specific colors of pencils from a jar without replacement. First, find the probability of each of the events separately, and then find their joint probability if events are happening successively by multiplying the individual probabilities.
Explanation:The subject of this question is probability, and it belongs to the field of Mathematics. You're asked to calculate the probability of selecting certain colors of pencils from a jar. The jar contains 4 red, 6 green, and 5 yellow pencils, making a total of 15 pencils. When a pencil is selected, it is not replaced back in the jar, affecting the probabilities of the following selections.
As an example, the probability of drawing a red pencil first (P(red)) would be the total number of red pencils divided by the total number of pencils which equals 4/15. If you then wanted to select a green pencil, the total number of pencils is now 14 (broader outcome space) as a pencil has been removed and not replaced. So, the probability of drawing a green pencil after a red one (P(green|red)) would be 6/14.
To find the probability of both events happening consecutively (drawing a red pencil then a green one), you would multiply the two probabilities together i.e., P(red and green) = P(red) · P(green|red). Applying the same steps to other combinations and you will be able to calculate all the different probabilities.

Two lines meet at a point that is also the endpoint of two rays. Set up and solve the
appropriate equations to solve for the values of angles x and y.
Answer:
Angle x=19°
Angle Y=53°
I might be wrong though.
Step-by-step explanation:
Since a right angle is 90° and a straight line is 180°,the other side(71+x)=90.Therefore,90-71=19,which is angle x.
There is another straight line,since angle x is 19°.All you have to do is subtract 71+37+19 from 180 to get Angle Y.The answer is 53°.
Angle X=90-71=19
Angle Y=180-37-71-19=53.
