A hot-air balloon has a 14-foot diameter that is being deflated at a rate of 0.25 feet per minute.
How many minutes, x, will it take before the balloon has shrunk to a diameter of 8 feet?
CLEAR CHECK
Write the equation that represents the situation.

x =
Solve for the time taken for the balloon to shrink to a diameter of 8 feet.
It will take
minutes.
Answer:
24 min
Step-by-step explanation:
14-8 is 6 so you need to shrink it 6 feet until it has a daimiter of 8.
6 divided by .25 is 24 so you have your answer
14-.25x=8
The equation is 14 - 0.25x = 8.
It will take 24 minutes for the balloon to shrink.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Given:
A hot-air balloon has a 14-foot diameter.
Rate of 0.25 feet per minute.
Now, equation to represent the situation is
14 - 0.25x = 8
On further solving
6= 0.25x
x= 6/0.25
x= 24
Hence, it will take 24 minutes for the balloon to shrink.

Measuring by using Trigonometry
Answer:
x approximately = 11.971, y approximately = 0.837
Step-by-step explanation:
the 12 ft is the hypotenuse of the right angle triangle formed
Cos (theta) = adjacent/hypotenuse
so Cos(4) = x/12, solving for x = 11.971
Sin(theta) = opposite/hypotenuse
so Sin(4) = y/12, solving for y = 0.837

Wyatt is going to a carnival that has games and rides. Each game costs $1. 25 and each ride costs $2. 75. Wyatt spent $20. 25 altogether at the carnival and the number of rides he went on is twice the number of games he played. Determine the number of games Wyatt played and the number of rides Wyatt went on.
In the carnival the number of games number of rides Wyatt went on is 3 and 6 respectively.
What is system of equation?
A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.
The number of unknown objects can be find using the system of solution.
Given information-
The cost of each game is $1.25.
The cost of each ride is $2.75.
Total amount of money spent by the Wyatt is $20.25.
The number of rides he went on is twice the number of games he played.
Suppose the number of games Wyatt played is x and the number of rides he went in the carnival is y.
As, the number of rides he went on is twice the number of games he played. Thus,
[tex]y=2x[/tex]
Let the above equation as equation one.
As total amount of money spent by the Wyatt is $20.25 and The cost of each game is $1.25 and the cost of each ride is $2.75. Thus,
[tex]1.25x+2.75y=20.25\\[/tex]
Put the value of y in the above equation from the equation one as,
[tex]1.25x+2.75(2x)=20.25\\1.25x+5.5x=20.25\\6.75x=20.25\\x=3[/tex]
Thus the number of games he played is 3.
Put this value of x in the equation one as,
[tex]y=2\times3\\y=6[/tex]
Thus the number rides Wyatt went on is 6.
Hence, In the carnival the number of games number of rides, Wyatt went on is 3 and 6 respectively.

What is the factored form of the polynomial? x2 − 15x 36 (x − 4)(x − 9) (x − 3)(x − 12) (x 4)(x 9) (x 3)(x 12).
Polynomials consist of both indeterminates and coefficients. The factors of the polynomial x² - 15x + 36 is (x-3)(x-12).
What are polynomials?A polynomial consists of both indeterminates and coefficients and involves mathematical operations such as addition, subtraction, multiplication, and division.
Given to us
x² - 15x + 36
To find the factors of the polynomial,
[tex]x^2 - 15x + 36 \\\\[/tex]
We will replace -15 with two numbers such that their sum is -15 while, their product must be 36.
[tex]x^2 - 15x + 36 \\\\ = x^2 -12x-3x +36\\\\[/tex]
now, we will take x as the common term from the first two-term, while 3 as the common term from the next two terms.
[tex]= x^2 -12x-3x +36\\\\= x(x-12) - 3 (x - 12)\\\\= (x-3)(x-12)[/tex]

Answer:
y = 175. x = 300. Disney vacation is 300 sold. Cars sold were 175.
Step-by-step explanation:
They want to raise $80,000. There are a total of 475 tickets.
150x + 200y (Disney Vacation + Win a car) = 80,000
x + y = 475.
__
y=475-x
150x+200(475-x)=80000
150x+95,000-200x=80,000.
-50x + 95,000 = 80,000.
-50x = -15,000
x = 300.
Disney vacation is 300 sold.
300 + y = 475.
y = 175.
Cars sold were 175.

Step-by-step explanation:
We can use Pythagorean theorem (a²+b²=c²) to answer this question by squaring the smallest 2 lengths then seeing if it equals the square of the 3rd length.
2²+3² = 4+9 = 13 ≠ 4²
12²+15² = 144+225 = 369 ≠ 20²
8²+9² = 64+81 = 145 ≠ 10²
