Given : A = 24 sq feet
A = 0.5 base x height
base = x , height = x+2
A = 0.5 x(x+2) = 24 sq feet
1) 0.5 x(x+2) = 24 (A)
2) x^2 + 2x - 48 = 0 (D)
To check the rest un-wrap the bracket:
x^2 + (x+2)^2 = 24
x^2 + x^2 + 4 + 4x = 24
2x^2 + 4x - 20 = 0
x^2 + 2x - 10= 0 (NO)
Likewise:
x^2 + (x+2)^2 = 100
x^2 + x^2 +4 + 4x = 100
2x^2 + 4x + 4 = 100
2x^2 + 4x - 96 = 0
3) x^2 + 2x - 48 = 0 (F)
To sum up: that's what apply:
1) 0.5 x(x+2) = 24 (A)
2) x^2 + 2x - 48 = 0 (D)
3) x^2 + 2x - 48 = 0 (F)
A family is considering selling a four-wheeler they had purchased for $8,200. They discover that a used four-wheeler depreciates at 12% per year. Write an equivalent equation using the monthly decay factor. What is the monthly decay rate of the four-wheeler?
The monthly decay factor is 0.0733 of the four-wheeler, and the equation is x = P(D)ˣ.
What does it mean by depreciation?Depreciation is an important subject in finance and economics since it is used to determine an asset's worth over time. For accounting and financial reporting needs, it enables people and businesses to monitor the fall in the value of their assets. Depreciation may be utilised to lower taxable income, which in turn lowers tax liabilities, hence it also plays a part in tax legislation.
The yearly decay factor is given as:
yearly decay factor = 1 - depreciation rate
yearly decay factor = 1 - 0.12
yearly decay factor = 0.88
Divide the yearly decay factor by 12:
monthly decay factor = yearly decay factor / 12
monthly decay factor = 0.88 / 12
monthly decay factor = 0.0733
n equivalent equation using the monthly decay factor as follows:
value after x months = initial value x (monthly decay factor)ˣ
x = P(D)ˣ
Hence, the monthly decay factor is 0.0733 of the four-wheeler, and the equation is x = P(D)ˣ

find the value of each variable using sine and cosine.
Answer:
p ≈ 11.3 , q ≈ 4.1
Step-by-step explanation:
using the cosine ratio in the right triangle
cos20° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{p}{12}[/tex] ( multiply both sides by 12 )
12 × cos20° = p , then
p ≈ 11.3 ( to 1 decimal place )
using the sine ratio in the right triangle
sin20° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{q}{12}[/tex] ( multiply both sides by 12 )
12 × sin20° = q , then
q ≈ 4.1 ( to 1 decimal place )

(40 points)
In accordance with the provided assertion, (A) the shorter leg is 3√3 inches and the hypotenuse is 6√3 inches (B) the longer leg is 4√3 cm and the hypotenuse is 8 cm.
What do maths lengths mean?The measurement or size of a thing end to end is referred to as its length. To put it another way, it is the bigger of the higher two or three dimensions of a geometric form or object.
For a 30°−60°−90° triangle, the ratios of the side lengths are:
Shorter leg: opposite 30° angle = xLonger leg: opposite 60° angle = x√3Hypotenuse: opposite 90° angle = 2xUsing these ratios, we can solve the problems:
If the longer leg is 9 inches, we have:Longer leg = x√3 = 9
x = 9/√3 = 3√3
Shorter leg = x = 3√3
Hypotenuse = 2x = 2(3√3) = 6√3
Therefore, the shorter leg is 3√3 inches and the hypotenuse is 6√3 inches.
2. If the shorter leg is 4 cm, we have:
Shorter leg = x = 4
Longer leg = x√3 = 4√3
Hypotenuse = 2x = 2(4) = 8
Therefore, the longer leg is 4√3 cm and the hypotenuse is 8 cm.

fx=x square -4 find codomain
So, the codomain of the function is the set of all real numbers: codomain = R.
What is function?In mathematics, a function is a rule that maps a set of inputs (domain) to a set of outputs (codomain) in such a way that each input is associated with exactly one output. A function can be represented using various notations, including equations, graphs, and tables. A function can be thought of as a machine that takes an input and produces an output. The input is usually represented by the variable x, and the output is represented by the variable y. The relationship between the input and output is defined by the function rule. Functions are used in many areas of mathematics, science, and engineering to describe various phenomena, such as motion, growth, and decay. They are also used to model and analyze data in statistics and economics, and to design and control systems in engineering and computer science.
Here,
The codomain is the set of all possible output values of a function.
For the given function, f(x) = x² - 4, we can see that the output values are obtained by squaring the input value, subtracting 4, and therefore can be any real number.
To find the codomain of the function f(x) = x² - 4, we need to determine the range of the function, which is the set of all possible output values.
Let y = f(x) = x² - 4.
To find the range, we need to solve for y:
y = x² - 4
y + 4 = x²
Taking the square root of both sides, we get:
x = ±√(y + 4)
Therefore, the range of the function is the set of all real numbers greater than or equal to -4, since y + 4 must be non-negative for real values of y:
range = {y | y + 4 ≥ 0} = {y | y ≥ -4}

The beach is 141 miles away. Your gas tank hold 18 gallons, and you use 3/8 of a tank to get to the beach.
a) What is your mpg (Miles per gallon)?
b) If gas costs $3.15 per gallon, how much did you spend to get to the beach?
*NEED ANSWERS NOW* FOR 28 POINTS im in 8th grade
You therefore paid $21.26 to travel to the beach.
How is a mile calculated?One mile is 5,280 feet long. To determine how many steps this should require walking a mile, simply split 5,280 feet by the length of your typical stride. For instance, if your typical stride is 2 feet, walking a mile will need 2,640 steps.
a) We must divide the total amount of miles travelled by the quantity of gas consumed in order to compute mpg (miles per gallon). If 141 miles are covered by 3/8 of a tank, we may calculate the tank's total capacity as follows:
18 gallons = 8/8 tank (full tank)
So, 3/8 tank = (3/8) x 18 = 6.75 gallons
Therefore, the mpg is:
mpg = distance traveled ÷ gas used
mpg = 141 miles ÷ 6.75 gallons
mpg = 20.89 miles per gallon (rounded to two decimal places)
b) The entire amount of gas consumed must be multiplied by the gallon price in order to get the cost of gas. Gas is expensive at:
Cost of gas = gas used x price per gallon
Cost of gas = 6.75 gallons x $3.15/gallon
Cost of gas = $21.26

Answer: x = 60 degrees
Step-by-step explanation:
As we see, there is a 90 degree angle formed the top left corner. You divided it by 2 and it is formed by both triangles and u get 45 degrees.
Now, according to angle sum property:
angle A + Angle B + Angle C = 180 degrees
therefore, 75 + 45 + angle c = 180
and by linear equation , angle c = 180 - [75 + 45]
= 180 -120
= 60
therefore, x = 60
Answer:
60 degrees
Step-by-step explanation:
A right triangle is 180 degrees. 60+75+a= 180degrees. It shows a right angle, with a line right at the middle. half of 90 is 45, so put that in the equation and you get 60+75+45=180 degrees. to solve for ? you want to take 45 + 75 + ? = 180 degrees 45 plus 74 is 135 so take 180-135 is 60. the ? will be 60 degrees.

Suppose that you put 2 dimes, 2 nickels, and 1 penny into a bag. a coin will be drawn from the bag and replaced 175 times. what is a reasonable prediction for the number of times a dime will be drawn?
A reasonable prediction for the number of times a dime will be drawn is approximately 90.
What is probability?Probability is the measure of how likely it is that an event will happen. The event is expressed as a number between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty. Probability is used in many areas, such as mathematics, science, engineering, and finance. For example, in mathematics, probability is used to determine the likelihood of an event occurring or a certain outcome occurring.
When 2 dimes, 2 nickels, and 1 penny are placed into a bag, there are 5 total coins. Therefore, the probability of drawing a dime is 2/5. When a coin is drawn and replaced 175 times, the probability of drawing a dime will remain the same (2/5) and the expected value of drawing a dime is 175*2/5 = 90.

Explain ratio.A collection of integers "a" as well as "b" that seem to be equal can be defined using the straightforward fraction calculation "a / b," at which "b" may be larger than zero. A ratio is created by combining two ratios. The ration would be 1:1 if there were just one male and three women. There are 1/4 guys and 3/4 women in the group. Portions can be a divide between different things, a number, or a specific portion of the volume of a component.
Here,
In events played, win:
Out of the 12 games contested, 8 were victories. We can split the numerator and denominator by 4 to decrease the ratio:
=> 8/12 = 2/3
The decreased win-to-games-played ratio is 2:3.

Answer:
Step-by-step explanation:
Using the remainder theorem we get:
[tex]f(-2)=-5[/tex], [tex]f(1)=4[/tex], and [tex]f(-1)=0[/tex]
So we get
[tex]f(-2)=(-8)(p-1)+4p-2q+r=-5[/tex]
[tex]-8p+8+4p-2q+r=-5[/tex]
[tex]-4p-2q+r=-13[/tex] [tex](a)[/tex]
[tex]f(1)=(p-1)+p+q+r=4[/tex]
[tex]2p+q+r=5[/tex] [tex](b)[/tex]
[tex]f(-1)=-(p-1)+p-q+r=0[/tex]
[tex]-q+r=-1[/tex] [tex](c)[/tex]
We need to solve (a), (b) and (c) simultaneously to find p,q, and r.
from [tex](c)[/tex] [tex]r=q-1[/tex]. Sub this into (a) and (b):
[tex]-4p-2q+(q-1)=-13 \rightarrow -4p-q=-12[/tex] [tex](d)[/tex]
[tex]2p+q+(q-1)=5 \rightarrow q=3-p[/tex] [tex](e)[/tex]
Sub (e) into (d) we get
[tex]-4p-(3-p)=-12 \rightarrow p=3[/tex]
Sub [tex]p=3[/tex] into [tex](e) \rightarrow q=0[/tex]
Sub [tex]p=3,q=0[/tex] into [tex](c) \rightarrow r=-1[/tex]

Describe Circle?A circle is a two-dimensional geometric shape that consists of a set of points in a plane that are equidistant from a fixed point called the center. The distance from the center to any point on the circle is called the radius.
A circle can be defined by its center point and radius or by its circumference, which is the distance around the perimeter of the circle. The circumference of a circle can be calculated using the formula:
C = 2πr
where C is the circumference, r is the radius, and π (pi) is a mathematical constant approximately equal to 3.14.
The center of the circle is (-5,-1) and its radius is the distance from the center to any point on the circle. Using the distance formula, we can find the radius:
r = √((0 - (-1))² + (-10 - (-5))²) = √(1 + 25) = √(26)
So, the equation of the circle in standard form is:
(x + 5)² + (y + 1)² = 26
Alternatively, in general form, it can be written as:
x² + y² + 10x + 2y - 20 = 0

A water trough is 10 m long and has a cross-section in the shape of an isosceles trapezoid that is 30 cm wide at the bottom, 90 cm wide at the top, and has height 60 cm. If the trough is being filled with water at the rate of 0.3 m3/min how fast is the water level rising when the water is 20 cm deep?
The speed at which the water level is rising when the water is 20 cm deep is 0.04285 m/min
How to solve thisUsing differentiation:
dV/dt = 0.3
find dh/dt
the width of the water level is dependent on the height
at height 0, width of 20
height 60, width of 80
when height increases by 1, width increases by 1
dh/dt = dw/dt
V = 0.5*(0.2 + (0.2+h))*h*10
V = 5*(0.4 + h)*h
V = 5h^2 + 2h
dV/dt = 5*2h(dh/dt) + 2(dh/dt)
when h = 0.5
0.1 = 5*2*0.5*(dh/dt) + 2(dh/dt)
0.1 = 5(dh/dt) + 2(dh/dt)
7(dh/dt) = 0.3
dh/dt = 0.04285 m/min

Rote tells the little monsters to do an overhead press every 12 seconds and a squat every 30 seconds. (For example, they should do their first squat 30 seconds into the drill.) How many times during the 200 second drill should the little monsters do an overhead press and a squat at the same instant?
The little monsters will do an overhead press and a squat at the same instant 3 times during the drill.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilising operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, Rote tells the little monsters to do an overhead press every 12 seconds and a squat every 30 seconds.
The prime factorization of 12 is 2² x 3, and the prime factorization of 30 is 2 x 3 x 5.
To find the smallest common multiple, we need to take the highest power of each prime factor that appears in either factorization. Thus, the smallest common multiple of 12 and 30 are:
2² x 3 x 5 = 60
This means that the little monsters will do an overhead press and a squat at the same instant every 60 seconds.
To find out how many times this will happen during the 200-second drill, we can divide 200 by 60:
200 ÷ 60 = 3 remainder 20
This means that there will be 3 complete cycles of both exercises during the 200-second drill, with an additional 20 seconds left over.
Therefore, the little monsters will do an overhead press and a squat at the same instant 3 times during the drill.

22. A small coffee company claims to include 11 ounces of coffee in every bag of ground coffee it produces. Out of a random sample of 250 bags, 50 of the bags contain only 10.9 ounces. Which inferences from the results of the random sample are reasonable? Choose all that are correct.
A. It can be inferred that 5% of the bags from a second random sample will contain more than 11 ounces.
B. It is likely that a second random sample of bags will show a much lower percentage of bags with only 10.9 ounces.
C. The percentage of all bags produced that contain less than 11 ounces is likely to fall between 15% and 25%.
D. It is likely that the company's claim is true because 20% of the bags in the sample contain 10.9 ounces.
E. It is unlikely that the company's claim is true because 20% of the bags in the sample contain 10.9 ounces.
From the percentage of the coffee bags with 10.9 ounces, we can see that it is unlikely that the company's claim is true because 20% of the bags in the sample contain 10.9 ounces.
What is meant by percentage?
A figure or ratio stated as a fraction of 100 is called a percentage. Frequently, it is indicated with the per cent sign, "%". If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage, therefore, refers to a component per hundred. Per 100 is what the word per cent means. As there is no unit of measurement for percentages, they are dimensionless numbers. This is because we divide numbers with the same units in percentage calculation.
Given,
Amount of coffee in A bag of ground coffee = 11 ounces
Number of bags = 250 bags
Number of bags which contain 10.9 ounces of coffee = 50
The percentage of bags which contain 10.9 ounces of coffee
= (50/250) × 100 = 20%
This percentage shows that the company's claim is not true because they claim every bag contains 11 ounces of coffee.
Therefore from the percentage of the coffee bags with 10.9 ounces, we can see that it is unlikely that the company's claim is true because 20% of the bags in the sample contain 10.9 ounces.
