Answer:
The fixed cost to insure jewellery is $0.602.
Step-by-step explanation:
We can use the information provided to set up a system of two equations in two variables, and then use the system to solve for the fixed cost of insuring the jewellery. Let x be the fixed cost and y be the percentage of the value of the jewellery. Then we can write the following two equations:
1000x + 1000y = 32 (1) (cost equation for insuring $1000 worth of jewellery)
3500x + 3500y = 44.5 (2) (cost equation for insuring $3500 worth of jewellery)
We can use either of these equation to solve for the fixed cost(x), to do that we can first solve for y from either of the equation, and then substitute it in other equation.
From equation (1)
y = (32 - 1000x) / 1000
then substitute this in equation (2)
3500x + 3500((32-1000x) / 1000) = 44.5
3500x + 32 - 3500x =44.5 - (1000x)
-20x = -12.05
x = 0.602 $
So, the fixed cost to insure jewellery is $0.602.
That means you have to pay $0.602 as a fixed cost, in addition to 0.01(y) as a percentage of the value of jewellery to insure it.

On solving the provided question, we can say that the required probability is = 13/204.
What is probability?Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true. An event's probability is a number between 0 and 1, where approximately 0 indicates how unlikely the event is to occur and 1 indicates certainty. A probability is a numerical representation of the likelihood or likelihood that a particular event will occur. Alternative ways to express probabilities are as percentages from 0% to 100% or from 0 to 1. the percentage of occurrences in a complete set of equally likely possibilities that result in a certain occurrence compared to the total number of outcomes.

So, the measure of x is 42 degrees
solve for x, Give your answer as a fraction or decimal rounded to the nearest hundredth.
Using the fact that the triangles are similar, we will see that:
x = 5.626
How to find the value of x?On the image we can see two triangles, such that one is inscribed on the other.
Just because of that, it is obvious that the two triangles are similar.
And because the triangles are similar, the quotients between correspondent sides must be equal, that allows us to write the equation:
3/x = 8/15
The quotient is "left side over the bottom side"
We can solve that equation for x:
3/x = 8/15
3 = (8/15)*x
(15/8)*3 = x
45/8 = x
5.625 = x
That is the value of x.

b. Find the probability that at least one of the two girls (Piper and Sedona) get to go to the show.
Probability that one of the girls (Piper as well as Sedona) will be able to attend the performance is one in five.
Explain the term Probability?Any probability is a mathematical representation of the likelihood or chance that a specific event will take place. All these proportions ranging from 0 to 1 and percentages varying from 0% through 100% can be used to describe probabilities.For the stated question-
There are 6 grandkids.There are two girls.Out of the six grandchildren, two are to be chosen.
There are 6C2 different ways to choose 2 out of 6 grandchildren.
6C2 = 6! / (6 - 2)!*2!
6C2 = 15
There are 15 different ways to choose two grandchildren out of six.There are 2C1 different ways to choose 1 of the 2 girls.
2C1 = 2
There are two different ways to choose one of the two girls.
Number of methods for choosing both girls = 2C2
Number of methods for choosing both girls equals one.
Probability of choosing 1 of the 2 grandchildren is 1/15.
The likelihood of choosing both girls is 2/15.
Probability that one of the females (Piper and Sedona) will be able to attend the performance is:
= 1/15 + 2/15.

XY is a diameter of a circle and Z is a point on the circle such that ZY=6. If the area of the triangle XYZ is 18 square root 3 find the length of arc XZ
4π
Step-by-step explanation:As shown in the diagram, triangle XYZ is a right triangle. Therefore, its area (A) is given by:
A = [tex]\frac{1}{2}[/tex] x b x h -------------(i)
Where;
A = 18[tex]\sqrt{3}[/tex]
b = XZ = base of the triangle
h = YZ = height of the triangle = 6
Substitute these values into equation(i) and solve as follows:
18[tex]\sqrt{3}[/tex] = [tex]\frac{1}{2}[/tex] x b x 6
18[tex]\sqrt{3}[/tex] = 3b
Divide through by 3
6[tex]\sqrt{3}[/tex] = b
Therefore, b = XZ = 6[tex]\sqrt{3}[/tex]
Now, assume that the circle is centered at O;
Triangle XOZ is isosceles, therefore the following are true;
(i) |OZ| = |OX|
(ii) XZO = ZXO = 30°
(iii) XOZ + XZO + ZXO = 180° [sum of angles in a triangle]
=> XOZ + 30° + 30° = 180°
=> XOZ + 60° = 180°
=> XOZ = 180° - 60°
=> XOZ = 120°
Therefore we can calculate the radius |OZ| of the circle using sine rule as follows;
[tex]\frac{sin|XOZ|}{XZ} = \frac{sin|ZXO|}{OZ}[/tex]
[tex]\frac{sin120}{6\sqrt{3} } = \frac{sin 30}{OZ}[/tex]
[tex]\frac{\sqrt{3} /2}{6\sqrt{3} } = \frac{1/2}{|OZ|}[/tex]
[tex]\frac{1}{12} = \frac{1}{2|OZ|}[/tex]
[tex]\frac{1}{6} = \frac{1}{|OZ|}[/tex]
|OZ| = 6
The radius of the circle is therefore 6.
Now, let's calculate the length of the arc XZ
The length(L) of an arc is given by;
L = θ / 360 x 2 π r ------------------(ii)
Where;
θ = angle subtended by the arc at the center.
r = radius of the circle.
In our case,
θ = ZOX = 120°
r = |OZ| = 6
Substitute these values into equation (ii) as follows;
L = 120/360 x 2π x 6
L = 4π
Therefore the length of the arc XZ is 4π
Please can someone help me with this circle theorem question and explain which rule would apply as I can’t seem to find which one I should be using please? :)
Answer:
∠LOP = 96°
Step-by-step explanation:
Given an inscribed angle of 48°, you want to know the measure of the central angle that subtends the same arc.
Inscribed angleThe measure of an inscribed angle is half the measure of the arc it subtends.
∠LMP = 1/2(arc LP)
48° = 1/2(arc LP) . . . . . . use the given value
96° = arc LP . . . . . . . . . multiply by 2
Central angleThe measure of an arc of a circle is the same as the measure of the central angle it subtends: the arc measure and its central angle measure are identical.
arc LP = ∠LOP
96° = ∠LOP
__
Additional comment
That's a long way of saying the central angle is twice the inscribed angle that subtends the same arc. ∠LOP = 2×∠LMP.

A regular heptagon has a radius of approximately 27.87 cm and the length of each side is 24.18 cm. What is the approximate area of the heptagon rounded to the nearest whole number
Rounded to the nearest whole number, the approximate area of the heptagon is 555 sq cm.
A heptagon is a seven-sided polygon. To find the area of a regular heptagon, we can use the formula:
Area = (7/4) * (perimeter) * (apothem)
where "perimeter" is the length of the heptagon's circumference and "apothem" is the distance from the centre to the midpoint of one of its sides. The radius of the heptagon is the apothem, which is 27.87 cm.
The perimeter of the heptagon can be calculated by multiplying the length of one side by the number of sides:
Perimeter = 24.18 cm * 7 = 168.26 cm
Now we can substitute these values into the area formula:
Area = (7/4) * 168.26 * 27.87
Area = approximately 554.55 sq cm.
Rounded to the nearest whole number, the approximate area of the heptagon is 555 sq cm.

What is the quotient?
What fraction is no solution?
No solution is a fraction that cannot be represented as a fraction of integers.
A fraction is a division of two numbers, and no solution occurs when the divisor is 0, because division by 0 is undefined.
For example, consider the fraction 2/0. This is a fraction with no solution because division by 0 is undefined. To explain this further, let's look at the formula for division: a/b = c. In this formula, a is the dividend, b is the divisor, and c is the quotient. In the fraction 2/0, the dividend is 2 and the divisor is 0, so when we try to calculate the quotient, we get c = 2/0. Since division by 0 is undefined, the result is no solution.
To summarize, no solution occurs when a fraction's divisor is 0 because division by 0 is undefined. This means that no fraction can be represented as a fraction of integers when the divisor is 0 because there is no solution.
