We round up to the nearest whole number because we are unable to have half a player. As a result, the softball team is allowed to send 7 players to the competition.
What are an example and an equation?The equal sign joins two expressions to create a mathematical formula called an equation. An illustration formula could be 3x - 5 = 16. By resolving this equation, we find that the value of the variable x is 7.
To begin, let's define a few variables:
x: The softball team's total roster size
y: the sum of the players' meal expenses
We can construct the equation shown below:
$1353 - $943.50 - $31.50x = y
Simplifying this equation, we get:
$409.50 - $31.50x = y
we can set up another equation:
y = $31.50x
Now we can substitute the second equation into the first equation to eliminate y:
$409.50 - $31.50x = $31.50x
Simplifying this equation, we get:
$409.50 = $63x
Dividing both sides by 63, we get:
x = 6.5

The current temperature is 48\deg F. It is expected to drop 1.5\deg F each hour. Which equation can be used to find in how many hours, h, the temperature will be 36\deg F?
Answer:
Let's start by defining some variables to represent the given information:
T0 = 48°F (the current temperature)
deltaT = -1.5°F/hour (the rate of change in temperature)
T = 36°F (the target temperature)
We want to find how many hours it will take for the temperature to drop from 48°F to 36°F, so let's call that time h. We can use the formula for the linear relationship between temperature and time:
T = T0 + deltaT * h
We want to solve for h when T = 36°F, so we can substitute the given values and solve for h:
36 = 48 + (-1.5) * h
-12 = -1.5h
h = 8
Therefore, it will take 8 hours for the temperature to drop from 48°F to 36°F, assuming the temperature continues to decrease at a rate of 1.5°F per hour.

How do u change this from vertex form y=2(x-2)^2+5 to standard form?
The standard form for the quadratic equation written in vertex form y = 2(x - 2)² + 5 is y = 2x² - 8x + 13.
What is a quadratic function?
A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.
To change the equation y = 2(x - 2)² + 5 from vertex form to standard form, we need to expand the squared term and simplify the expression.
Here are the steps -
Start with the vertex form: y = 2(x - 2)² + 5.
Expand the squared term using the formula (a - b)² = a² - 2ab + b².
In this case, a = x and b = 2, so we have -
y = 2(x - 2)(x - 2) + 5
y = 2(x² - 4x + 4) + 5
Multiply the coefficient 2 by each term inside the parentheses -
y = 2x² - 8x + 8 + 5
Combine the constant terms -
y = 2x² - 8x + 13
This is the standard form of the quadratic equation.
In standard form, the quadratic equation is written as y = ax² + bx + c, where a, b, and c are constants.
In this case, a = 2, b = -8, and c = 13.
Therefore, the standard form is y = 2x² - 8x + 13.

Qe. For the following arithmetic serles, find: a_(1),d,a_(n),n 1a.27,31,35,dots, 783,a_(1)= d= a_(n)= n^(2)
For the given arithmetic series, a_(1) = 27, d = 4, a_(n) = 783, n = 190, and n^(2) = 36100.
The given arithmetic series is 27, 31, 35,..., 783.
To find the first term, a_(1), we can simply look at the first term in the series. Therefore, a_(1) = 27.
To find the common difference, d, we can subtract the first term from the second term, or the second term from the third term. Therefore, d = 31 - 27 = 4.
To find the nth term, a_(n), we can use the formula a_(n) = a_(1) + (n - 1)d. We know that a_(1) = 27, d = 4, and a_(n) = 783, so we can plug these values into the formula and solve for n:
783 = 27 + (n - 1)(4)
756 = (n - 1)(4)
189 = n - 1
n = 190
Therefore, the nth term is 190.
To find the value of n^(2), we can simply square the value of n:
n^(2) = 190^(2) = 36100

How many numbers cansisting of 3 digits can be made from 1,2,3,4,5, and 6 if letter A repitition is allowed, letfer B repitition is not allowed.
Answer:
If repetition of letter A is allowed and letter B cannot be repeated, then there are two cases to consider when constructing a 3-digit number:
Case 1: The first digit is letter A. In this case, there are 6 options for the first digit (since any of the 6 digits can be used), and there are 5 options for each of the remaining digits (since letter B cannot be repeated). Therefore, the total number of 3-digit numbers that can be formed in this case is:
6 x 5 x 5 = 150
Case 2: The first digit is not letter A. In this case, there are 5 options for the first digit (since letter A cannot be repeated), and there are 5 options for each of the remaining digits (since letter B cannot be repeated). Therefore, the total number of 3-digit numbers that can be formed in this case is:
5 x 5 x 4 = 100
To get the total number of 3-digit numbers that can be made from 1, 2, 3, 4, 5, and 6 with letter A repetition allowed and letter B repetition not allowed, we add the number of possibilities from Case 1 and Case 2:
Total = 150 + 100 = 250
Therefore, there are 250 different 3-digit numbers that can be made from 1, 2, 3, 4, 5, and 6 with letter A repetition allowed and letter B repetition not allowed.
There are 720 numbers consisting of 3 digits that can be made from 1, 2, 3, 4, 5, and 6 if letter A repetition is allowed and letter B repetition is not allowed.
This can be calculated by taking the number of possible combinations for each digit (6 for A, 5 for B, 4 for C) and multiplying them together: 6 x 5 x 4 = 120. Since there are 6 possible numbers for each digit, there are 120 combinations for a 3-digit number. Then, multiplying 120 by 6 (since repetition is allowed) yields 720 possible 3-digit numbers.

Step-by-step explanation:
You want to show the triangle defined by points P(3,2),Q(6,2) and R(6,6) is a scalene triangle.
Side lengthsWe observe that points P and Q have the same y-coordinate, so lie on the horizontal line y=2. The length PQ is 6 -3 = 3 units.
Points Q and R have the same x-coordinate, so lie on the vertical line x=6. The length QR is 6 -2 = 4 units.
These legs are different lengths and are at right angles to each other. The third leg, the hypotenuse, will be longer than either of them.
The triangle's sides are unequal, so the triangle is a scalene triangle.

The wind farms in southern California contain wind generators whose power production varies directly with the cube of the wind's speed. one such generator produces 1000W of power in a 25mph wind, find the power it generate in a 35mph wind.
The wind generator will produce 2744W of power in a 35mph wind.
Determine the generate powerTo find the power generated by the wind generator in a 35mph wind, we can use the formula P = kV³, where P is the power generated, k is a constant, and V is the wind's speed.
First, we need to find the value of k. We can do this by plugging in the given values of P and V into the formula and solving for k:
1000W = k(25mph)³ 1000W = k(15625mph³)
k = 1000W/15625mph³
k = 0.064W/mph³
Now that we have the value of k, we can plug it back into the formula along with the new wind speed of 35mph to find the power generated:
P = (0.064W/mph³)(35mph)³
P = (0.064W/mph³)(42875mph³)
P = 2744W
Therefore, the wind generator will produce 2744W of power in a 35mph wind.

The sides of the triangle circumscribed about a circle of radius 4 and divided on one side by the circle into segments of length 6 and 8 are 6, 8, and 4.
The triangle circumscribed about a circle of radius 4 and divided on one side by the circle into segments of length 6 and 8 can be found using the Law of Cosines. The Law of Cosines states that c2 = a2 + b2 - 2ab cos C, where c is the length of the hypotenuse, a and b are the lengths of the other sides, and C is the angle opposite side c.
We know the hypotenuse of this triangle is 8, as it is the length of one of the segments on the side of the triangle. We also know that angle C is 90° as it is a right triangle.
Therefore, using the Law of Cosines we can find the length of the other side of the triangle, which is 6. The equation is 82 = 62 + a2 - 2(6)(a)cos(90°). Solving this equation, we find that a = 4.
Therefore, the sides of the triangle circumscribed about a circle of radius 4 and divided on one side by the circle into segments of length 6 and 8 are 6, 8, and 4.

PLEASE HELP !!!!!!! A group of 1,254 people is going on a boat tour if each boat holds 8 people how many boats will they need ?
We need to round up to the next full number because we are unable to equation have a fraction of a boat. The organization will thus require 157 boats to hold the entire 1,254 persons.
What is equation?Using the equals symbol (=) to indicate equivalence, a math equation links two statements. Algebraic equations prove the equality of two mathematical expressions by a mathematical assertion. The equal sign, for example, provides a gap between the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. You can use a mathematical formula to understand the connection between the two phrases that are written on opposite sides of a letter. Most of the time, the logo and the particular software match. e.g., 2x - 4 = 2 is an example.
We may divide the total number of persons by the capacity of each boat to determine the number of boats required to hold a party of 1,254 individuals:
8 individuals per boat times 1,254 passengers is 156.75 boats.
We need to round up to the next full number because we are unable to have a fraction of a boat. The organization will thus require 157 boats to hold the entire 1,254 persons.

Find a model for the Body Mass Index (BMI) of a person, given
that BMI varies directly as a person’s weight in pounds and
inversely as the square of the person’s height in inches. If a

The model for the BMI of a person is:
BMI = (152100/weight in pounds)/(height in inches)^2
The Body Mass Index (BMI) of a person can be calculated using the formula:
BMI = (weight in pounds)/(height in inches)^2
In this case, the BMI varies directly as a person's weight in pounds and inversely as the square of the person's height in inches. This means that as the weight increases, the BMI increases and as the height increases, the BMI decreases.
To find a model for the BMI of a person, we can use the formula:
BMI = k(weight in pounds)/(height in inches)^2
Where k is a constant of proportionality. To find the value of k, we can use the given information that a 6ft 6in tall person has a BMI of 25.
First, we need to convert the height from feet and inches to inches. 6ft 6in is equivalent to 78 inches. Then, we can plug in the values into the formula and solve for k:
25 = k(weight in pounds)/(78 inches)^2
25(78 inches)^2 = k(weight in pounds)
152100 = k(weight in pounds)
Therefore, the model for the BMI of a person is:
BMI = (152100/weight in pounds)/(height in inches)^2
This model can be used to calculate the BMI of a person given their weight in pounds and height in inches.

Step-by-step explanation:
Find the average rate of change of the given function on the
interval [5,10].
h(x)=3x2+6x−7
The average rate of change of the function h(x)=3x2+6x−7 on the interval [5,10] is 94.6.
The average rate of change of the function h(x)=3x2+6x−7 on the interval [5,10] is calculated by taking the change in the y-value (h(10) - h(5)) and dividing it by the change in the x-value (10-5):
Average rate of change = (h(10)-h(5))/(10-5)
= (3(10)2+6(10)-7 - (3(5)2+6(5)-7))/(10-5)
= (745-272)/5
= 473/5
= 94.6
Therefore, the average rate of change of the function h(x)=3x2+6x−7 on the interval [5,10] is 94.6.

What is a fraction?
A fraction is used to represent the portion/part of the whole thing. It represents the equal parts of the whole. A fraction has two parts, namely numerator and denominator. The number on the top is called the numerator, and the number on the bottom is called the denominator. The numerator defines the number of equal parts taken, whereas the denominator defines the total number of equal parts in a whole.
Movie duration = 1 3/4 = 7/4
Duration of movie watched = 3/5
Duration watched = 7/4 - 3/5
Duration watched = 23/20
Duration watched = 1 3/20 (mixed fraction)
