Answer:
The diameter is approximately 8.9 cm
Step-by-step explanation:
The circumference is given by
C = pi *d
28 = pi *d
Divide each side by pi
28/pi = d
We can approximate pi by 3.14
28 /3.14 =d
8.917 = d
The diameter is approximately 8.9 cm

The triangles shown below must be congruent is True statement.
What is Congruency?Two geometric figures are said to be congruent, or to be in the relationship of congruence, if one can be superimposed on the other and they correspond throughout.
As, Two triangles are congruent if their two angles and included sides are equivalent to the other triangle's two angles and included side.
Confirm that the triangles are congruent:
Both of the triangles given are right-angled triangles.
The included side between the angles 45° and 90° in both triangles is 12 units.
This is a necessary condition for the ASA congruence rule.
Thus, the given statement is True statement.

A polynomial has zeros of 7, 6.
What is the minimum degree of the polynomial?
The minimum degree of the polynomial is 2.
Given the polynomial has zeros of 7, 6 means it has total of 2 zeroes. So it has only two factors possible [tex](x-7) and (x-6)[/tex] and on multiplying these factors we finally had a polynomial of degree 2 like[tex](ax^{2} +bx+c)[/tex].
So the given polynomial be a quadratic polynomial which has degree of 2.
Hence the minimum degree of the polynomial is 2.

A use bike costs $75 a new one costs $300. how many times more expensive is a new bike compare with a use bime
Answer:
300-75=225
Step-by-step explanation:
The proportionality constant is k = 4
The cost of the new bike is 4 times the cost of used bike
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportionality constant be represented as k
Now , the cost of used bike A = $ 75
The cost of new bike B = $ 300
The proportionality constant k = cost of new bike B / cost of used bike A
Substituting the values in the equation , we get
The proportionality constant k = 300/75
The proportionality constant k = 4
Therefore , the new bike is 4 times the cost of used bike
Hence , the proportionality constant is 4

write the converse of the statement below. then determine whether the statement is true or false. If false, give a counterexample. Conditional Statement: If 2 angles are corresponding in parallel lines, then they are congruent.
Answer:
Converse statement is ''If two angles are congruent, then they are corresponding angles in parallel lines''.
The converse statement is false.
Step-by-step explanation:
Statement is ''If 2 angles are corresponding in parallel lines, then they are congruent.''
Converse statement is ''If two angles are congruent, then they are corresponding angles in parallel lines''.
Consider the figure.
Here,
[tex]l||m[/tex]
As ∠1 and ∠2 are alternate interior angles,
∠1 ≅ ∠2
(if two lines are parallel then each pair of alternate interior angles is equal)
So, ∠1 ≅ ∠2 but ∠1 and ∠2 are alternate interior angles not corresponding angles.
The converse statement is false.

In this plan, there is new policy that states that if a high school has less than 100 students, then the school will be shut down. Calamanco High School has a population of 1,417 students, but it is losing students at an average rate of 109 students per year. This school used to house more than 5,000 students but the district has been struggling in recent years and losing people to more affluent nearby districts and cities.
