The circumferance of the given circle is C = 8π.
What is a circle?A circle is a shape consisting of all points in a plane that are at a constant distance from a given point called the center. Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.The general form of the equation of a circle is:x² + y² + 2gx + 2fy + c = 0.
The standard equation of a circle is -(x - x₁)² + (y - y₁)² = r²
The parametric equation of circle can be written as -x² + y² + 2hx + 2ky + C = 0 where x = - h + rcosθ and y = - k + rsinθ.
Given is a circle that has a diameter of 8 meters.
We can write the circumferance of the circle as -
C = 2πr
C = 2π (d/2)
C = 2π (8/2)
C = 8π
Therefore, the circumferance of the given circle is C = 8π.

Step-by-step explanation:
The lifespan of a hamster is 4 years less than that of a rabbit. The lifespan of a raccoon is 2 times that of the hamster. If the total lifespan of the animals is 24 years, calculate the longevity for the rabbit.
Answer:
9 years
Step-by-step explanation:
Let
Lifespan of rabbits = x
Lifespan of hamster = x - 4
Lifespan of raccoon = 2(x - 4)
Total lifespan of animals = 24
Total = rabbits + hamster + raccoon
24 = x + (x - 4) + 2(x - 4)
24 = x + x - 4 + 2x - 8
24 = 4x - 12
24 + 12 = 4x
36 = 4x
x = 36/4
x = 9 years
longevity for the rabbit = 9 years
Lifespan of rabbits = x = 9
Lifespan of hamster = x - 4
= 9 - 4
= 5
Lifespan of raccoon = 2(x - 4)
= 2(9 - 4)
= 2(5)
= 10
Total lifespan of animals = 24

Answer:
3x*59x=
Step-by-step explanation:
Answer:
126 degrees
Step-by-step explanation:
The opposite angles of a parallelogram are equal, so 4x + 2 = 8x - 50. By subtracting 4x from both sides of this equation, we get that 2 = 4x - 50. Adding 50 to both sides yields 52 = 4x, and dividing by 4 gives us that x = 13.
By substituting this, we see that the measure of angle A is 4(13)+2, which is 54 degrees. Angle B is supplementary to angle A, so its measure is 180-54, which is 126 degrees.
What is the length of the hypotenuse? 13 in 45 marking brainliest and giving thanks to all!!
Answer:
the Last angle equal 45
because we have 90 and 45 so to complete the 180 Degrees we have to put 45

Answer: 36.25°
Step-by-step explanation:
Use SOHCAHTOA (sin, cosine and tangent)
SOHCAHTOA:
SOH: Sin(θ) = Opposite / Hypotenuse
CAH: Cos(θ) = Adjacent / Hypotenuse
TOA: Tan(θ) = Opposite / Adjacent
When you have an angle that you want to solve, look at what information you're given. In this problem, we're give nthe sides that are opposite to and adjacent to the angle we want to solve. So, we use TAN.
And just as a note, θ this symbol is called theta, and it represents an angle.
TAN(θ) = Opposite / Adjacent = 11/15
Then, use the inverse of tan (you can find the button on a calculator). You can use the inverse of sine, cosine or tangent whenever you want to switch them from one side of the equation to the other.
TAN(θ) = [tex]\frac{11}{15}[/tex]
θ = [tex]tan^-1(\frac{11}{15} )[/tex]
Then, using a calculator, solve. The answer is about 36.25°

lemonade to the school picnic, and
Shelby brought 16 quarts of orangeade.
How many gallons did the two girls
bring to the school picnic?
Answer: 25 Gallons
Step-by-step explanation:
My answer is correct because, if were just finding out how much gallons did both the girls bring then we just have to add 9 plus 16. 9 plus 16 equals 25.

Determine the constant that should be added to the binomial so that it becomes a perfect square trinomial. Then write and factor the trinomial. x2 + 16x
Answer:
[tex]$64, \ (x+8)^2$[/tex]
Step-by-step explanation:
A perfect square trinomial is defined as an expression that is obtained from squaring a binomial equation. The perfect square trinomial is in the form of [tex]$ax^2+bx+c$[/tex].
The given expression is :
[tex]$x^2+16x$[/tex]
The co-efficient of the x-term in [tex]$x^2+16x$[/tex] is '16'.
So half of the term 16 ,
[tex]$\frac{16}{2} = 8$[/tex]
and [tex]$(8)^2=64$[/tex]
Now add 64 to the expression:
[tex]$x^2+16x+64$[/tex]
Therefore, the perfect square trinomial is
[tex]$(x+8)^2=x^2+16x+64$[/tex]

much will be left after 22 days?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Radioactive decay.
N(t) = 72(1/2)^22/11
==> N(t) = 72 (1/2)^2
==> N(t) = 72/4
==> N(t) = 18 grams.
So the remaining would be 18 grams.

Which way is the wind blowing in relation to the land and ocean?
Answer: Hope This Helps!
Step-by-step explanation:
This wind happens to be the sea breeze. The sea breeze is a thermally produced wind blowing during the day from the cool ocean onto the adjoining warm land. It is caused by the difference in the rates of heating between the land and the ocean. The bigger the difference in temperature, the stronger the wind.
Answer:
When the air mass above the land becomes cooler than the air mass over water, the wind direction and convective cell currents reverse and the land breeze blows from land out to sea.

What is an
equation of the line that passes through the points (-4, -3) and
(3, -3)?
Answer:
y=-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-3-(-3))/(3-(-4))
m=(-3+3)/(3+4)
m=0/7
m=0
y-y1=m(x-x1)
y-(-3)=0(x-(-4))
y+3=0(x+4)
y+3=0

Does anyone know how to solve this?
Answer:
$ 22.5
Step-by-step explanation:
B(x) = 30.50 - 0.20x
Notice that x defines the number of prints.
For prints = x = 40
B(40) = 30.50 - 0.20(40)
B(40) = 30.50 - 8
B(40) = 22.5
Remaining amount is $22.5
B(x) is defined as at starting you had $30.50 then you kept on spending with a period of 20 cents(= 0.20 dollar). So 30.50 kept on decreasing by 0.20. Each time you spend, you give 0.20.
That's why the function is 30.50 - 0.20x.
Where x is the nunber of times you spend(buying prints)

A toy remote control car is driven across a table. Based on the graph, how far from the start line will the car be after 5 seconds?
50 cm
100 cm
120 cm
160 cm
Answer:
100 cm
Step-by-step explanation:
This is a linear function with an equation of y = 20x.
Plug 5 in for x to get 100 as your answer.
Answer: 100 cm
Step-by-step explanation: Since the car can travel 20 cm per second and it traveled 80 cm in 4 sec, then it can travel 100 cm in 5 seconds
(Tip: If it asks to show your work, try drawing a ratio table and write the centimeters it travels per second .)
