A circle is divided into 4 sector in the ratio 4,3,1 and 2 .the circumference of the circle is 190cm.calculate
i.the area of the circle
ii.the length of the arc of the smaller sector
III. the area of the smallest sector
Answer:
i. area of the circle = 2872.75 cm²
ii. length of the arc of the smaller sector = 19 cm
III. area of the smallest sector = 287.3 cm²
Step-by-step explanation:
The formula for calculating the circumference of any circle is 2*π*r
The formula for calculating the area of any circle is π*r²
1. "forget" all extra info and concentrate on the one important piece of info, which is circumference of the circle is 190cm. Use the right formula and calculate r.
2*π*r = 190
r = (190)/(2*π)
r = 30.2394391874601
r = 30,24 cm
2. Now use r in the other formula to calculate the total area of the circle in cm².
π* 30.2394391874601)² = 2872.75 cm²
3. Given there are 4 sector in the ratio 4,3,1,2. the total number of ratios is the sum of 4+3+1+2 = 10.
Wich means that 10 ratios account for the total area of the circle. and also for the the total circumference.
The smaller sector has the ratio of 1, which accounts for 1/10 arc of the total circomference:
1/10 *190 = 19 cm
4. The smaller sector has the ratio of 1, which accounts for 1/10 part of the total area:
1/10 * 2872.75 = 287.3 cm²
And that's all there is to it.

Calculate the mean and standard deviation of the data set ...
Answer:
Mean: 12.9
Standard deviation: 14.8
Step-by-step explanation:
The mean is calculated adding all of the values and dividing by the number of elements:
[tex]m=\frac{2+3+7+12+1+4+27+49+11}{9}=\frac{116}{9}=12.9[/tex]
to find the standard deviation, we first find the variance (which is defined as the sum of all the elements subtracting the mean and squared and then dividing by the total amount of elements):
[tex]v=\frac{(2-12.9)^2+(3-12.9)^2+(7-12.9)^2+(12-12.9)^2+(1-12.9)^2+(4-12.9)^2+(27-12.9)^2+(49-12.9)^2+(11-12.9)^2}{9}\\[/tex]
[tex]v=\frac{1978.89}{9}\\[/tex]
[tex]v=219.88[/tex]
Noe that we have the variance, we can calculate the standard deviation.
The stardard deviation is defined as the squared root of the variance:
[tex]standardDeviation=\sqrt{v}[/tex]
we substitute the variance:
[tex]standardDeviation=\sqrt{219.88} \\standardDeviation=14.8[/tex]
Thus, the answer is:
Mean: 12.9
Standard deviation: 14.8

What is the solution to the system of equations below?
Answer:
HOPE IT HELPED!!!!!!
Step-by-step explanation:
2x + 3y = 17
3x + 6y = 30
TIMES THE FIRST EQUATION BY TWO:
2(2x + 3y = 17)
4x + 6y = 34
NOW OUR EQUATIONS ARE:
4x + 6y = 34
3x + 6y = 30
SUBTRACT THE FIRST EQUATION BY THE SECOND ONE:
4x + 6y = 34
(-) 3x + 6y = 30
x = 4
THEREFORE:
x = 4
NOW SUBSITUTING x IN THE FIRST EQUATION:
4(4) + 6y = 34
16 + 6y = 34
6y = 34 - 16
6y = 18
y = 18/6
y = 3
THEREFORE:
X = 4
Y = 3

find the area of triangle two sides of which are 8cm and 11cm and the perimeter is 32cm with Herons formula
Answer:
8√30
Step-by-step explanation:
The length of the third side is 32 - 8 - 11 = 13. s (which is half of the perimeter) is 32 / 2 = 16 so the answer is:
√s(s-a)(s-b)(s-c) = √16 * (16 - 8) * (16 - 11) * (16 - 13) = √16 * 8 * 5 * 3 = √1920 = 8√30
Q3: Determine the difference 34.7 – (–8.6). Determine la diferencia para 34.7 - (–8.6).

Since there are two negative signs, it cancels out, and becomes an adding sign or a positive.
Thus, it is now, 34.7 + 8.6
Solve:
34.7 + 8.6 = 43.3
Therefore, the difference of 34.7 - (-8.6) is 43.3

Answer:
x4
Step-by-step explanation:
going down on the x axis
Answer:
0 = x+y -2
Step-by-step explanation:
The general form of a line is 0 = Ax + By + C where A is a positive integer
First write it in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is
m = (y2-y1)/(x2-x1) (2,0) and (0,2)
= (2-0)/(0-2)
= 2/-2
= -1
and the y intercept is 2
y = -1x +2
Subtract y from each side
0 = -x -y +2
Multiply by -1
0 = x+y -2
Find the values of x, y and z from the given parallelograms.
please help please it's a request
Answer:
(ii) (x, y, z) = (110°, 30°, 30°)
(iii) (x, y, z) = (110°, 70°, 70°)
Step-by-step explanation:
The things you need to know and use are ...
Opposite angles of a parallelogram are congruent.
Adjacent angles of a parallelogram are supplementary.
Alternate interior angles between a transversal and parallel lines are congruent.
Corresponding angles where a transversal crosses parallel lines are congruent.
__
(ii) Angles B and D are opposite, so congruent:
x = 110°
Angle DAB is supplementary to angle B, so is 70°. That means z is ...
z = 70° -40° = 30°
Angle y is "alternate interior" relative to z, so is congruent to z:
y = 30°
__
(iii) Angle x is adjacent to angle N, so is supplementary to 70°.
x = 180° -70° = 110°
Angle y is opposite angle N, so is congruent.
y = 70°
Angle z is corresponding to angle N, so is congruent. (It is also "alternate interior" with respect to angle y, so is congruent to y.)
z = 70°

Solution(s) : Option # 2 and # 4
Step-by-step explanation:
One quick way to identify which solutions are accurate would be adding the exponents of the terms provided ( b, y, c etc ). As you can see in each example two expressions are being multiplied, and hence the exponents of each term are being added.
Therefore the second and fourth example are correct, as 4 + 5 = 9, the co - efficient of y. And 3 + 4 = 7, the co - efficient of x.
Check :
[tex]5y^4\left(2y^5\right)[/tex] = [tex]5\cdot \:2y^{4+5}[/tex] = [tex]5\cdot \:2y^9[/tex] = [tex]10y^9[/tex]

If h(x) is the interse of f(x), what is the value of h(f(x))?
O 0
0 1
f(x)
Answer:
Step-by-step explanation:
Your options for solutions are nonsensical. We'll go about this a different way...namely, I'll tell you about a function and its inverse and then you can pick the answer from your options, as best as it will fit.
If f(x) = x + 1 and f(x) is the same thing as y, you can say that y = x + 1
If h(x) is the inverse of f(x), we have to find what h(x) is. The way to do that is to switch the x and y coordinates in f(x) and solve for the new y.
f(x) = y = x + 1 then x = y + 1 and y = x - 1.
That tells us the inverse of f(x), aka h(x). If we then take the composition of f(x) into h(x) we will find its value.
h(f(x)) ---> h(x + 1) = (x + 1) - 1 and
h(f(x)) = x
This will ALWAYS BE TRUE, NO MATTER WHAT FUNCTION YOU PLUG IN.
Fact: the composition of an inverse into its function = x
Fact: the composition of a function into its inverse = x

Calculate the length of AC to one decimal place in the trapezium below.
Answer:
First we will split trapezium on two geometric figure.
One is rectangle and the second is right triangle.
When we subtract 11-4=7cm we get one cathetus of the right triangle a=7cm also we know hypotenuse which is c=16cm.
We will use Pythagorean theorem to find the second cathetus b
b=√16∧2-7∧2= √256-49= √207 ≈ 14.39cm =DC =>
AC =√(DC)∧2+(AD)∧2= √14.39∧2+11∧2= √207+121= √328= 18.1cm
AC=18.1cm
Good luck!!
The length of trapezium is = 18.1cm
What is trapezium?A convex quadrilateral having exactly one set of opposite sides that are parallel to one another is called a trapezium. When drawn on a piece of paper, the trapezium is a two-dimensional shape that resembles a table. A quadrilateral is a polygon in Euclidean geometry that has four sides and four vertices. With four sides, four angles, and four vertices, a trapezium also has four of each.
Split trapezium into two geometric figure.
Then,
One is rectangle
And the second is right angle triangle.
Subtract 11-4=7cm
we get one length of the right triangle
a = 7cm
We know hypotenuse which is c = 16 cm.
Apply Pythagorean theorem to find the second length b
b =√(16²-7²)
= √256-49
= √207
≈ 14.39cm
AC =√[(DC)²+(AD)²]
= √(14.39²+11²)
= √207+121
= √328
= 18.1cm
Hence,
AC = 18.1cm

Betty sets up a lemonade stand and charges $1 per glass. It cost her $50 to set up the stand. Which function gives the profit, p, she makes by selling g glasses of lemonade? The number of glasses of lemonade, g, that Betty needs to sell to make a profit, p, if the setup cost her $50 is given by the function p(g) = .
Answer:
p = g - 50
Step-by-step explanation:
profit = income - expenses
income = 1 * g = g
expenses = $50
p = g - 50
If g = 50, then
p = 50 - 50 = 0
If she sells 50 glasses of lemonade, she breaks even. That means she makes no profit, but also she loses nothing.
If she sells more than 50 glasses, then she makes a profit.

Triangle R T S is sitting on a horizontal line. Line S R extends through point Q to form exterior angle T R Q. Angle R T S is (25 x) degrees. Angle T S R is (57 + x) degrees. Exterior angle T R Q is (45 x) degrees.
Answer:
x = 3
Question: Find the value of x.
Step-by-step explanation:
Given:
- Triangle R T S is sitting on a horizontal line
- Line S R extends through point Q to form exterior angle T R Q
- m∠RTS is (25 x)°, m∠TSR is (57 + x)° , m∠TRQ is (45 x)°
Lets find the value of x
∠TRQ is an exterior angle of Δ RTS at the vertex R
The opposite interior angles to vertex R are ∠RTS and ∠TSR
∴ m∠TRQ = m∠RTS + m∠TSR
m∠TRQ = (45 x)°
m∠RTS = (25 x)°
m∠TSR = (57 + x)°
Substitute these measures in the equation above
45 x = 25 x + 57 + x
45 x = 26 x + 57
19 x = 57
x = 3
