Answer:
[tex]17.3\:\mathrm{m}[/tex]
Step-by-step explanation:
The circumference of a circle is given by [tex]C=2r\pi[/tex], where [tex]r[/tex] is the radius of the circle.
By definition, the radius is equal to half the diameter. Therefore, a circle with a diameter of 5.5 meters has a radius of [tex]5.5\cdot \frac{1}{2}=2.75[/tex] meters.
Thus, the circumference of the silo must be:
[tex]C=2\cdot 2.75\cdot \pi=17.2787595947\approx \boxed{17.3\:\mathrm{m}}[/tex](rounded to one decimal place as requested by question).
*Units for circumference should be in the same units as the radius/diameter is given in, since the circumference just refers to the perimeter of a circle.
**Your work for question 2 should include an equals sign, not an addition sign, between the part where you're adding the sevens and multiplying them: [tex]\implies 7+7+7+7+7+7\boxed{=}7\cdot 6[/tex]
What is the surface area of this right cone?
Answer:
Step-by-step explanation:
Slant height s = 12
Radius r = 8
Lateral area of cone = πrs = 96π units²
Base area of cone = πr² 64π units²
Surface area = 96π + 64π = 160π units²

Solve for x in the triangle round your answer to the nearest tenth BRAINLIEST
Answer:
x = 16.4
Step-by-step explanation:
For right-angle triangles, we can use the trigonometry equations;
In this case, we need to use the sine equation in particular:
sinθ = opposite/hypotenuse
sin(66) = x/18
x = 0.91...(18)
x = 16.4438... ⇒ 16.4
Which is the domain of the function f(x) =
12
- 2?
Vx+4
O A. x20
O
B. x>-4
o
C. x>-2
D. x>-4
E. all real numbers
The domain of the function is x> -4.
The correct option is B.
We have the function
f(x) = 12/ √(x+ 4) - 2
Now, putting f(x) = 0
12/ √(x+ 4) - 2 = 0
12 - 2√(x+ 4) = 0
-2√(x+ 4) = -12
√(x+ 4) = 6
Taking Square on both side we get
x+ 4 = ±36
x = ± 36 - 4
x = 32 or x= -40
Thus, the domain of the function is x> -4.

Vincent has $5 bills and $20 bills. He has a total of 24 bills and the total amount is $210. How many $5 bills does he have?
Help pls
Answer:
18
Step-by-step explanation
Let's say that the amount of 5 dollar bills is x and 20 dollar bills is y, with this we can make an equation
x + y = 24
With that we can say that
5x + 20y = 210
Because that is how much each bill costs and the amount of which will equal a total of 210
Solve this systems of equations using elimination
5x + 5y = 120
-5x - 20y = -210
-15y = -90
y = 6
Plug in y = 6 to the first equation.
x + 6 = 24
x = 18
18 is the amount of 5 dollar bills.

What are the roots of the equation x^2+8x+32=0 in simplest a+bi form?
Answer:
x = -4 ± i4
Step-by-step explanation:
This is a quadratic equation with coefficients {1, 8, 32}. We apply the quadratic formula to solve for x. The first step is to find the 'discriminant,' b^2 - 4 ac, which here is (8)^2 - 4(1)(32), or 64 - 128, or -64.
A negative discriminant indicates that this quadratic has two unequal complex roots.
-b ± √(b^2 - 4ac)
The formula is x = ----------------------------
2a
which, when evaluated at a = 1, b = 8 and c= 32, yields
-8 ± √(-64)
The formula is x = ----------------------------
2(1)
or:
-8 ± i√64
The formula is x = ----------------- = x = -4 ± i4

Mahak is measuring the maximum space inside a watering can. This is a measure of A weight. B capacity.
Answer:
B. capacity.
Step-by-step explanation:
In this scenario, Mahak is measuring the maximum space inside a watering can. Thus, this is a measure of capacity because it gives the exact information as to the quantity of water the watering can hold at any given time.
Basically, the capacity of a container is a measure of the volume of fluid or any other substance that it is able to hold, which is typically measured in litres or cubic centimeters.
For example, if the shape of the watering can is cylindrical; its capacity (volume) would be measured using a mathematical expression.
Mathematically, the volume of a cylinder is given by the formula;
V = πr²h
Where;
V is the volume of a right circular cylinder.r represents the radius of the cylinder.h represents the height of the cylinder.Vera is 11 years old and her brother is 9 years old. They shared 60 oranges in the ratio of their ages. How many more oranges does Vera get?
Vera gets a total of 6 more oranges than her brother
How to determine how many more oranges Vera gets?Their ages are given as
Vera = 11 years old
Her brother = 9 years old
When represented as a ratio, we have
Vera : Her brother = 11 years old : 9 years old
Remove the units
So, we have
Vera : Her brother = 11 : 9
Multiply both sides of the ratio by 3
This gives
Vera : Her brother = 33 : 27
When the above ratios are added, the solution is 60 i.e. the total number of oranges
So, we calculate the difference instead
Vera - Her brother = 33 - 27
Evaluate
Vera - Her brother = 6
Hence, she gets 6 more oranges

12- 1/5r = 2r + 1
R=??
Answer:
r = 5
Step-by-step explanation:
12 - 1/5r = 2r + 1
12 - 0.2r = 2r + 1
12 - 0.2r + 0.2r = 2r + 0.2r + 1
12 = 2.2r + 1
12 - 1 = 2.2r + 1 - 1
2.2r = 11
2.2r ÷ 2.2 = 11 ÷ 2.2
r = 5
Answer:
r = 5
Step-by-step explanation:
12- 1/5r = 2r + 1
12 = 11/5r + 1
5(11) = (11/5r)5
55 = 11r
r = 5
