3a² - 66a + 1.
What is Expression?
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
We have to Subtract 11a²+42a-6 from 14a²-24a+7.
So, the subtraction is as follows
= 14a²-24a+7 - ( 11a²+42a-6)
= 14a²-24a+7 - 11a² - 42a + 6
= 14a²- 11a² -24a - 42a + 7- 6
= 3a² - 66a + 1

A farmer owns 30 acres of land. Of the 30 acres, only 65% can be farmed. How many acres are available for farming?
Final answer:
To calculate the available farming land, 65% of the total 30 acres is determined, resulting in 19.5 acres available for farming.
Explanation:
To find out how many acres are available for farming, we need to calculate 65% of the total 30 acres of land the farmer owns.
The calculation is as follows:
Convert the percentage to a decimal by dividing by 100: 65% / 100 = 0.65.Multiply the total acres by the decimal: 30 acres × 0.65 = 19.5 acres.Therefore, 19.5 acres of the farmer's land can be used for farming.

You accidentally dropped a coin from the top of 7 stairs. What is the probability that it will land below the sixth step and heads up?
Answer:
The probability that it will land below the sixth step and heads up is [tex]\frac{1}{14}[/tex]
Step-by-step explanation:
Given : You accidentally dropped a coin from the top of 7 stairs.
To find : What is the probability that it will land below the sixth step and heads up?
Solution :
A coin has two sides - head and tail.
Probability of getting head is
[tex]P(H)=\frac{1}{2}[/tex]
Total stairs are 7.
Coin will land below the sixth step i.e. it land on 7th step.
So, Probability of landing coin on below the sixth step is
[tex]P(L)=\frac{1}{7}[/tex]
Now, The probability that it will land below the sixth step and heads up is
[tex]P=\frac{1}{2}\times \frac{1}{7}[/tex]
[tex]P=\frac{1}{14}[/tex]
Therefore, The probability that it will land below the sixth step and heads up is [tex]\frac{1}{14}[/tex]

Angelo family drove 254.6 miles their car used 19 gallons of gasoline describe the cars gas mileage
The Angelo family's car has a gas mileage of approximately 13.4 miles per gallon, calculated by dividing the total miles driven (254.6 miles) by the gasoline used (19 gallons).
Explanation:A car's gas mileage is calculated by dividing the total number of miles driven by the amount of gasoline used. In this case, the Angelo family drove 254.6 miles and used 19 gallons of gasoline. So, to figure out their car's gas mileage, you would divide 254.6 miles by 19 gallons.
254.6 miles ÷ 19 gallons = 13.4 miles per gallon
Therefore, the gas mileage of the Angelo family's car is approximately 13.4 miles per gallon.

The height of a cone is equal to the diameter of the base. what expression represents the volume of the cone, in cubic units? πx3 πx2 2πx3 4πx3
The formula for a cone is given as:
V = π r^2 h / 3 ---> 1
Where,
V = volume of the cone
r = radius of the circle base of the cone
h = is the perpendicular length from the center of the base of the cone to the tip at the top
It was given that:
h = d
but d = 2 r, therefore:
h = 2 r
Substituting this to equation 1:
V = π r^2 (2 r) / 3
V = 2 π r^3 / 3
Since r = x, the answer from the choices is:
2πx3
The expression representing the volume of the cone is (2/3)πx^3, where x represents the cone's radius.
Step 1: Identify Key Information
We are given that the height (h) of the cone is equal to the diameter (d) of the base. The diameter is twice the radius (r).
Step 2: Apply Formula and Substitute
The formula for the volume of a cone is:Volume (V) = (1/3) * π * r^2 * h
Since h = d = 2r, we can substitute:V = (1/3) * π * r^2 * (2r)
Step 3: Simplify the Expression
V = (1/3) * π * r^2 * 2rV = (2/3) * π * r^3Choose the correct simplification of (4x3 − 3x − 7) + (3x3 + 5x + 3)
After performing the addition operation on both expressions, the resulting simplified expression is 7x^3+2x-4

Use the arc length formula and the given information to find r. Show your work for full credit. s = 8.1 ft θ = (3.14/3)rad r = ?
Answer:
The length of the radius is 7.74 ft.
Step-by-step explanation:
It is given that the length of arc is s=8.1 and central angle of arc is [tex]\theta=\frac{3.14}{3}[/tex] in radian.
The formula for arc length is
[tex]s=r\theta[/tex]
Where, s is length of arc, θ is central angle of arc in radian and r is the radius of the circle.
Substitute s=8.1 and [tex]\theta=\frac{3.14}{3}[/tex] in the above formula.
[tex]8.1=r\times \frac{3.14}{3}[/tex]
[tex]8.1=r\times 1.0467[/tex]
Divide both sides by 1.0467.
[tex]\frac{8.1}{1.0467}=r[/tex]
[tex]7.73860705073=r[/tex]
[tex]r\approx 7.74[/tex]
Therefore the value of r is 7.74 ft.
