feet?
Total 24 minutes, x, will it take before the balloon has shrunk to a diameter of 8 feet.
In the given question, we have to find how many minute, x, will it take before the balloon has shrunk to a diameter of 8 feet.
From the given question, a hot-air balloon has a 14-foot diameter.
Hot-air balloon is being deflated at a rate of 0.25 feet per minute.
So the slope will be = -0.25, the negative sign is there because hot-air balloon is being deflated.
Let the amount of air left in the hot-air balloon at time n minutes is A(n) feet diameter.
The initial value of A(n) is 14-foot diameter.
Thus when n = 0, the value A(n) will be 14.
So, we can write the relation as
A(n) = -0.25n + 14
We need to find the amount left after x minute. So n = x.
The balloon has shrunk to a diameter of 8 feet. So A(n) = 8 feet
Now the equation is
8 = -0.25x + 14
Subtract 14 on both side, we get
-0.25x = -6
Divide by -0.25 on both side, we get
x = 24

The value 750 in equation 300x + 750 = 23,250 represents the initial amount in the club account.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 9 is an equation.
We have,
Initial amount in the club account = m
Amount raised by each member = n
All members raised the same amount.
Number of members = x
The total amount raised by all the members = p
nx + m = p
This is similar to the equation 300x + 750 = 23,250
So,
n = 300
m = 750
p = 23,250
Now,
m = 750 is the initial amount in the club account.

What is the area of the triangle having sides 3 cm 4 cm and 5 cm?
The area of a triangle with sides 3 cm, 4 cm, and 5 cm is 6 cm² using Heron's formula.
Step 1: First, calculate the semi-perimeter of the triangle by adding the three sides of the triangle together and dividing by 2. In this case, the semi-perimeter would be (3 + 4 + 5) / 2 = 6 cm.
Step 2: Next, use the semi-perimeter and the three side lengths of the triangle to calculate the area. The formula for Heron's formula is:
Area = √(s(s-a)(s-b)(s-c))
Where s is the semi-perimeter, and a, b, and c are the three sides of the triangle.
So, plug in the values,
Area = √(6(6-3)(6-4)(6-5))
Area = √(632×1)
Area = √(36)
Area = 6 cm²
Therefore, the area of the triangle is 6 cm²

A total of 64 musicians entered a music contest, and of these musicians are guitarists. Some of the guitarists play jazz solos, and the rest play classical solos. The ratio of the number of guitarists playing jazz solos to the total number of guitarists in the contest is 1: 4. How many guitarists play classical solos in the contest
The number of guitarist who plays classical solos in the contest is 30.
What is Ratio?Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.
The ratio of a and b is denoted as a : b.
Given that,
Total number of musicians entered in the contest = 64
5/8 of these musicians are guitarists.
Number of guitarists = (5/8) × 64 = 40
Also we have,
Ratio of number of guitarists playing jazz solos to the total number of guitarists = 1 : 4 = 1/4
That is, of the 4 guitarists, 1 is a guitarist playing jazz solos.
Multiplying both numerator and denominator with 10, 1/4 = 10/40
So of the 40 guitarists, 10 number of guitarists play jazz solos.
Number of guitarists who play classical solos = 40 - 10 = 30
Hence 30 guitarists play classical solos.

What is coordinates of a vertex in factored form?The simplest way to obtain a vertex in factored form is to locate the axis of symmetry, substitute that as x, and then solve for y. With the formula x=r+s2, which means that r and s are the zeros, it is possible to determine the axis of symmetry. x is the vertex's x-component, or the axis of symmetry. Using the formula x=-b/2a, find the quadratic's vertex, and then substitute the result for y in the original equation. After that, enter the vertex as a variable in the vertex form equation, y=a(x-h)2+k. (A remains the same, h equals x, and K equals y.)The factored form of a quadratic expression is one in which the quadratic expression is the product of two factors, each of which is a linear expression.

The solution to the equation 6y - 2(y + 1) = 3(y - 2) 6 is y = -34. So, the correct answer to the question is a. y = -10.
What is algebraic equation ?
An algebraic equation is a mathematical statement that asserts the equality of two expressions, each of which is made up of numbers and/or variables. The expressions are separated by an equal sign (=). The goal of solving an algebraic equation is to find the value(s) of the variable(s) that make the equation a true statement.
To find the solution to the equation 6y - 2(y + 1) = 3(y - 2) 6, we must first simplify both sides of the equation by following the order of operations (PEMDAS). First, we simplify the right side of the equation: 3(y - 2) 6 = 3y - 6 * 6 = 3y - 36. Next, we simplify the left side of the equation: 6y - 2(y + 1) = 6y - 2y - 2 = 4y - 2.
Now we have the equation: 4y - 2 = 3y - 36
Next, we can add 2 to both sides of the equation and get: 4y = 3y - 34
Finally we subtract 3y from both sides of the equation and get: y = -34
Therefore, the solution to the equation 6y - 2(y + 1) = 3(y - 2) 6 is y = -34. So, the correct answer to the question is a. y = -10.
