A farmer owns 30 acres of land. Of the 30 acres, only 65% can be farmed. How many acres are available for farming?
Answers
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.

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 = ?
Answers
s=θ(r)
arc length = angle x radius
2.46888m(or 8.1 ft) = (π/3) x r
[tex]r = (\pi /3)/2.46888[/tex]
[tex]r = .425m [/tex]
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.
The length of a rectangle is 2 cm less than 6 times the width. find the possibilities for the width of the rectangle such that the area is not more than 840 cm2
Answers
To solve this problem, let us first assign the variables. Let us say that:
l = length of rectangle
w= width of rectangle
The given problem gives us the relation that:
l = 6 w – 2 ---> 1
We know that the formula for area of rectangle is given as:
A = l w ---> 2
Substituting equation 1 into 2:
A = (6 w – 2) w
A = 6 w^2 – 2 w
The area must not be greater 840 cm^2, therefore:
840 cm^2 = 6 w^2 – 2 w
w^2 – (1/3) w = 140
By completing the square:
w^2 – (1/3) w + (1/36) = 140 + (1/36)
(w – 1/6)^2 = 5041/36
w – 1/6 = ± 11.83
w = -11.66, 12
Therefore the maximum value that the width can take is 12 cm. Therefore the possibilities of width such that the area does not exceed 840 cm^2 is from 1 to 12 cm.
Answer:
1 cm to 12 cm

What is 15 minus 3 and 7 8ths
Answers
Solution of equqation 15 - 3 7/8 is 11 1/8.
To solve 15 - 3 7/8, you need to follow these steps:
Convert the mixed number 3 7/8 to an improper fraction.Subtract this fraction from 15.First, convert 3 7/8 to an improper fraction:
3 7/8 = (3 * 8 + 7) / 8 = 31/8Next, convert 15 to a fraction with a common denominator of 8:
15 = 120/8Now you subtract the improper fraction from the whole number fraction:
120/8 - 31/8 = (120 - 31) / 8 = 89/8Convert the result back to a mixed number:
89/8 = 11 1/8So, 15 minus 3 and 7/8 is 11 1/8.

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
Answers
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^3You 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?
Answers
1/2 because there is a 50/50% chance its either heads or tails
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]

what is the length of a circle that has a central angle of 98 degrees and 6 cm?
Answers
S = (n/360)(Perimeter)
The variable n is the measure of the central angle that intercepts the arc. In this case, n = 98°. The perimeter of the circle is equal to 2πr. Substituting the values,
S = (98°/360°)(2×π× 6 cm)
S = 10.26 cm
There is also a formula that is easier to remember, but you have to convert degrees to radians. The conversion is 180° = π radians. The formula is
S = rθ
S = (6 cm)(98°)(π/180°)
S = 10.26 cm
Thus, the arc length is 10.26 cm.

Angelo family drove 254.6 miles their car used 19 gallons of gasoline describe the cars gas mileage
Answers
Gas mileage = 254.6 miles/19 gallons
Gas mileage = 13.4 miles/gal
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

Step-by-step explanation:
From the graph we can see the line is intersecting y axis at (0,2).
Therefore, y intercept of the graph = 2
Therefore, the initial value of the graph = 2
Also there as two point from which line is passing (0,2) and (1,3)

Answers
f(x)=a(x-h)²+k
vetex is (h,k)
and a is te leading coefient
if directix is below the focus, then it opens up and a is positive
if directix is above focus, then it opens down and a is negaitve
vertex is in between directix and focus
so
(3,-1) and y=1
-1<1
so directix is above
a is negative
directly in between
distance from -1 to 1 is 2
2/2=1
1 above (3,-1) is (3,0)
vertex is (3,0)
