The area of a circular pond with a radius of 8 ft is, 18.67 m².
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We have to given that;
The radius of circle = 8 feet
Now, We know that;
⇒ 1 feet = 0.3048 m
⇒ 8 feet = 8 × 0.3048 m
= 2.4384 m
We know that;
⇒ Area of circle = πr²
Substitute all the values, we get;
⇒ Area of circle = 3.14 × (2.4384)²
⇒ Area of circle = 3.14 × 5.94
⇒ Area of circle = 18.67 m²

A correlation coefficient is a numerical index that reflects the relationship between two variables.
What is the correlation coefficient?The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
1 indicates a strong positive relationship.-1 indicates a strong negative relationship.A result of zero indicates no relationship at all, therefore, an independent variable.The given blank in the sentence can be filled with two variables.

Determine if you can make a triangle from the 3 given side lengths.
3 cm, 16 cm, and 8 cm
Check the picture below.
we have three sides, let's look at the two smaller sides first.
check picture atop
if we move the sides closer and ever closer to each other, to the extent that one is right on top of the other, what is the length of the red side? Well, assuming the two smaller sides are one pancaked on top of the other, the red side will be as long as 8 - 3 = 5. However, the sides can't be on top of each other, because if that's so, we have a flat-line, and thus we wouldn't have a triangle. So whatever the third side may be, it must be greater than 5.
check picture below
Now, if we move the sides away from each other, farther and farther to the extent that one is parallel to the other, then the third side will just be as long as 3 + 8 = 11. However, we can't do that, because if that were to happen, we again will have a flat-line and not a triangle. So whatever the third side may be, it must be less than 11.
well, needless to say, the 16 cm side, is outside that range, so, hmmm no dice.
What is the length of the altitude of the equilateral triangle below?
"

60"
Answer:
F. 12
Step-by-step explanation:
There are two right triangles.
Hence, we can solve for the missing side using the Pythagorean Theorem using one of these triangles.
Let's take the left one.
a² = (8√3)² - (4√3)²a² = 192 - 48a = √144 a = 12The length of the altitude is 12.
The correct option is : F. 12
The length of an altitude is 12 units.
The correct option is 12.
What is Pythagoras' theorem?Pythagoras' Theorem states that the square of the hypotenuse side of a right-angled triangle is equal to the sum of the squares of the other two sides.
As per the information provided, it is given that the triangle is an equilateral triangle.
The side of the triangle is 8√3 units.
To find the length of the altitude of the equilateral triangle:
Let the length of altitude is h units.
Then, as per Pythagoras' theorem,
h² = (8√3)²- (4√3)²
h² = -16(3) + 64(3)
h = -48 + 192
h² = 144
h = 12
Therefore, h = 12 units.

A veterinary office pays PupFood $32. 75 for each bag of dog food. If the office spent $655, how many bags of food did they purchase? (Use only a number for your answer)
Answer:
20 Bags
Step-by-step explanation
The total costs would be given by the formula:
Total $ = (Bags of Food)*(Cost/bag)
We know total cost and price per bag:
$655 = (Bags of Food)*($32.75/bag)
Bags of Food = ($655/$32.75)
Bags of Food = 20 Bags
4 divided by 1/3 is 12 becuase
Answer:
12
Step-by-step explanation:
When we divide fractions we multiply instead since it's the opposite of division and we do the reciprocal. Reciprocal means we flip the fraction from 1/3 to 3/1
So:
4÷1/3 would become 4×3/1
4×3/1 is the same as 4×3
So:
4×3=12
That's why the answer is 12.

At a high school, the probability that a student is a senior is 0.25. The

is a senior and plays a sport is 0.08.
What is the probability that a randomly selected student plays a sport, given
that the student is a senior?
• A. 0.08
O B. 0.32
• C. 0.17
D. 0.25
Answer:
B. 0.32
I guessed and it was right
The probability that a randomly selected student plays a sport, given that the student is a senior, is 0.32.
The correct answer is B. 0.32.
To find the probability that a randomly selected student plays a sport, given that the student is a senior, we can use the formula for conditional probability:
P(plays a sport | senior) = P(plays a sport and senior) / P(senior)
Given that P(plays a sport and senior) = 0.08
and P(senior) = 0.25,
we can substitute these values into the formula:
P(plays a sport | senior) = 0.08 / 0.25
P(plays a sport | senior) = 0.32
Therefore, the probability that a randomly selected student plays a sport, given that the student is a senior, is 0.32.

a system of equations is shown. 4x-y=5 y=-3 what is the value of x in the solution to this system
Answer:
x = 1 / 2 ( or ) 0.5
Step-by-step explanation:
4x - y = 5
Substitute the value of y = - 3 in the given equation,
4x - ( - 3 ) = 5
4x + 3 = 5
4x = 5 - 3
4x = 2
x = 2 / 4
x = 1 / 2 ( in terms of fraction )
( or )
x = 0.5 ( in terms of decimal )
Note : -
- ( - 3 ) can be written as - 1 x ( - 3 ).
When a negative number is multiplied with another negative number, the result will be positive number.
Hence,

A rectangle with a perimeter of 18 miles and a width of 7 miles.
What is the length of the rectangle?
Answer:
2 miles
Step-by-step explanation:
A rectangle has two widths
7 + 7 = 14
18-14=4
It also has two lengths
4/2=2
2 miles
Hope this Helps
Happy Earth day
Answer:
2 miles
Step-by-step explanation:
Perimeter is figured out by adding all 4 sides of a rectangle.
So if the width is 7 miles on 1 side, the other width side is also 7 miles.
If the perimeter was 18 miles and 14 miles of that was the width on both sides, that leaves only 4 miles left for the 2 length sides. That means each length side is 2 miles.

There are 5 red, 18 green, and 17 blue pens in a bag. Leah selects a pen 800 1
times without looking. Before each selection, she replaces the pen in the
bag. Write and evaluate an expression to predict the number of times Leah
selects a pen that is red or green. *
The number of times Leah is expected to select a pen that is red or green is 460 and the expression is 23/40 * 800
How to determine the expected selection of red or green pen?The distribution of the pen is given as:
Red = 5
Green = 18
Blue = 17
The number of red or green pen is:
Red or green = 5 + 18
Evaluate
Red or green = 23
In a selection of 800 pen, the expected number of red or green pen is:
E(x) = 23/(5 + 18 + 17) * 800
Evaluate the sum
E(x) = 23/40 * 800
Evaluate the expression
E(x) = 460

We have the equation [tex]\sf -11=t-5}[/tex]. And what we need to do is solve for the variable, t.
↪
To solve for the variable, we should ensure that the variable we need to solve for is all by itself on one side of the equation.
T is not all by itself, [tex]\because[/tex] 5 is subtracted from it.
So what do we do to "remove" that 5 from there? Wouldn't it be great if there was a zero instead of the -5?
We can make that happen by adding 5 to both sides.
We add 5.
[tex]\sf -11=t-5+5}\\-11=t+0}\\-11=t[/tex]
[tex]\bullet[/tex] However, we also need to add 5 to the other side.
[tex]\sf -11+5=t}[/tex]
Simplify!
[tex]\sf -6=t}[/tex]
NOW the variable, t, is all by itself.
↪
Tip: Why not check your work and make sure there are no mistakes?
We can proof-read, but we can also do this:
Plug in the solution (t=-6) into the original equation.[tex]\sf -11=-6-5}[/tex]. Upon simplification, we obtain
[tex]\sf -11=-11[/tex]
Since both sides (the left hand side, l.h.s. and the right hand side, r.h.s. are the same, our solution, t=-6, is correct. Great job!
