This is calculated by multiplying the cost of each game (25 cents) by the number of times Larry will have to play (16 times) to last 4 minutes. It will cost Larry $1.00 to last 4 minutes before he is knocked out.
Larry started playing a video game and was knocked out in 30 seconds. He then decided to play again and this time he was able to play 30 seconds longer than the previous game. He kept repeating this and was able to play 30 seconds longer each time. Since it cost him 25 cents to play each game, it will therefore cost him $1.00 to last 4 minutes before he is knocked out. This is calculated by multiplying the cost of each game (25 cents) by the number of times Larry will have to play (16 times) to last 4 minutes. Therefore, 25 cents x 16 = $1.00.

We need to use the concept of Percentile Rank. The Percentile Rank for score 71 is 33.33 and the score of Viktor is 84.
What is Percentile Rank?According to the pupils in the particular norm group, a student's performance is shown by their percentile rank. Let's try to put the percentile rank in a tidy mathematical equation now that you are clearer on what it actually is. A collection of values A = x1, x2, x3,..., xn with N values will be used in our attempt to calculate the percentile rank of the data point xm. In this scenario:
PR = L / N × 100 where:
PR stands for percentile rank and has a range of 0 to 100;
L is the quantity of values in set A that are less than or equal to the value of your data, xm; and
The entire collection of values in A has a total of N values.
Calculation:Given some of the test scores. Arrange the test Scores in ascending order.
A={58,64,66,70,71,75,77,80,84,85,87,90,93,95,96}
N=15
Now find out the values in the set which are less than or equal to 71.
L=5
Apply, PR=L/N ×100
⇒PR=5/15 × 100
PR=33.33 is the Percentile Rank of score 71.
Viktor is in 60th percentile, so find out L.
⇒60=L/15 ×100
⇒L=60×15/100
L=9.
So 84 is Viktor Score.
We need to use the concept of Percentile Rank. The Percentile Rank for score 71 is 33.33 and the score of Viktor is 84.

zaida took a square piece of paper and folded two of its sides to the diagonal, as shown, to obtain a quadrilateral. what is the size of the largest angle of the quadrilateral?
Answer:
112.5°
Step-by-step explanation:
The corner of the square that remains is a 90° angle.
The opposite corner started as a 90° angle that was folded in half into two 45° angles. Then each 45° angle was folded in half into two 22.5° angles. Then you put two 22.5° angles together to make a 45° angle.
So far we have two opposite angles measuring 90° and 45°.
The quadrilateral is a kite. The other two opposite angles are congruent.
The sum of the measures of the angles of a quadrilateral is 360°.
360° - 90° - 45° = 225°
225°/2 = 112.5°

Part A
Consider the function f(x) = x3 − 4x2 + 2. Calculate the limit of the difference quotient at x0 = 3 for f(x).
Part B
Find the equation of a line passing through the same point that f(x) passes through at x = 3 with a slope equal to the limit you found in part A.
Part C
Graph the function f(x) and the line you identified in part B. How do the graphs relate to each other? What does the slope of the line represent about the function at the given point?

Part A: Calculation of the limit at x = 3In order to find the limit of the function, we can factorize the numerator by factoring out (x-3). Limit [tex][tex](x 3)\frac{(x^3 - 27)}{ (x-3)} )[/tex]Now, factorize x³ - 27 to get the difference of cubes. The
limit equation becomes, Limit [tex](x 3) \frac{ (x-3)(x² + 3x + 9)]}{(x-3)}[/tex] Now, we can cancel out the term (x-3) from the numerator and denominator to get the limit equation as
Part B: Limit [tex](x 3) (x^2 + 3x + 9)[/tex]The limit of the function at x = 3 is the value of the function as x approaches 3. By plugging in x = 3 in the equation above, we get, Limit ([tex](x 3) (x^2 + 3x + 9) = (3)^2 + 3(3) + 9[/tex] = 27Part B: Equation of line through f(3) with slope = 27
The slope of the line is 27, and it passes through the point (3, f(3)). The equation of the line can be found using the point-slope form. [tex]y - f(3) = 27(x - 3)[/tex]
Part C: Simplifying the equation, we get,[tex]y = 27x - 78[/tex] Part C: Graphical representation of the line and the function
The graph of the function f(x) is a parabola opening upward with a vertex at (3, 0). The slope of the line is positive, which means the line will have a positive y-intercept.
The line will intersect the y-axis at (0, -78).Both the graph of the function and the line pass through the point (3, 0). The line is tangent to the graph of the function at that point.
The slope of the line represents the instantaneous rate of change of the function at the point (3, 0). It is the same as the limit we calculated in Part A.

Mary deposits $260.00 into a new savings account.
The account earns 2.5% simple interest per year. No
money is added or removed from the account for
5 years. What is the total amount of money in her
savings account at the end of the 5 years?
A) $292.50
C) $65.00
D) $325.00
B) $32.50
Answer:
A
Step-by-step explanation:
To solve this problem, we need to first find out how much interest the account earns each year. If the account earns 2.5% simple interest per year, and it starts with an initial balance of $260, then the interest earned each year is 0.025 * $260 = $6.50.
Over 5 years, the account will earn a total of 5 * $6.50 = $<<5*6.5=32.50>>32.50 in interest.
To find the total amount of money in the account at the end of the 5 years, we need to add the interest earned to the initial balance of the account. The total amount of money in the account will be $260 + $32.50 = $<<260+32.5=292.50>>292.50.
Therefore, the total amount of money in the account at the end of the 5 years is $292.50.
Answer:
A) $292.50
Step-by-step explanation:
Simple Interest Formula
A = P(1 + rt)
where:
A = Final amountP = Principal amountr = Interest rate (in decimal form)t = Time (in years)Given:
P = $260.00r = 2.5% = 0.025t = 5 yearsSubstitute the given values into the formula and solve for A:
⇒ A = 260(1 + 0.025 · 5)
⇒ A = 260(1 + 0.125)
⇒ A = 260(1.125)
⇒ A = 292.50
Therefore, the total amount of money in her savings account at the end of 5 years is $292.50.

A basketball team had a mean score of 66 points per game. The total number of points they scored is 924. How many games have they played?
Answer:
the team played a total of 14 games
Step-by-step explanation:
To find the number of games the team played, you can divide the total number of points they scored by the mean number of points they scored per game. In this case, you would divide 924 by 66 to get:
[tex]924 / 66 = < < 924/66=14 > > 14 games[/tex]
So, the team played a total of 14 games.
A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,200 ft Determine the flag's width and length if the length is 480 ft greater than the width.
The flag's width is ft. Its length is ft.
4
Answer:
the width of the flag is 310 ft and the length is 790 ft.
Step-by-step explanation:
Let "w" be the width of the flag and "l" be the length of the flag. We can set up the following equation to represent the problem:
2w + 2l = 2200
We know that the length of the flag is 480 ft greater than the width, so we can set up the following equation to represent this relationship:
l = w + 480
We can substitute the second equation into the first equation to solve for the width of the flag:
2w + 2(w + 480) = 2200
This simplifies to:
4w + 960 = 2200
Subtracting 960 from both sides gives us:
4w = 1240
Dividing both sides by 4 gives us:
w = 310
So the width of the flag is 310 ft.
We can use this value to find the length of the flag by substituting it into the equation l = w + 480:
l = 310 + 480
This simplifies to:
l = 790
So the length of the flag is 790 ft.
Therefore, the width of the flag is 310 ft and the length is 790 ft.

how many one-to-one functions are there from a set containing 5 elements to a set containing 6 elements?
There are 5x6=30 one-to-one functions from a set containing 5 elements to a set containing 6 elements.
A one-to-one (or injective) function is a type of mathematical function that maps each element of one set to one, and only one, element of another set. In other words, a one-to-one function is a function that has a unique output for each input. To calculate the number of one-to-one functions from a set containing 5 elements to a set containing 6 elements, we can use the formula f(x)=y, where x is the number of elements in the original set and y is the number of elements in the target set. In this case, x = 5 and y = 6, so f(x) = 6. Since each element in the original set must be mapped to a unique element in the target set, the total number of one-to-one functions is equal to the product of x and y, or 5 x 6 = 30.

What was the total percent
discount Sam got?
Answer:
1/ Total percent of discount is 40%
2/ The original price is $520.70
Step-by-step explanation:
1/ We add a 25% discount on every TV store, a 10% discount on purchases, 5% discount for paying cash, so the total is a 40% discount.
2/ Now, let's find the original price
100% - 40% = 60%
We know that the 60% he has to pay is $371.93, so we have to find the 40% discount.
40% = 0.4
Take 371.93 times 0.4 = $148.77
Then we add both numbers together
148.77 + 371.93 = $520.70
