Overall, 120 6th grade scholars voted in theclass president election. How many votes did each class president candidate receive?
Answers
The number of votes that each class president candidate receive is 48 and 72 votes respectively.
How to calculate the values?Your information is incomplete. Therefore, an overview will be given. Let's say that A received 40% of the vote and B got 60% of the vote.
The number of votes gotten by each person will be:
A = Percentage × Number of votes
= 40% × 120
= 0.4 × 120.
= 48 votes.
B. = Percentage × Number of votes
= 60% × 120
= 0.6 × 120.
= 72 votes.
Therefore, A got 48 votes and B had 72 votes.

Given ^PRS = ^CFH, find the values of x, y, and z.
Answers
Answer:
x = 23, y = 7, z = 11
Step-by-step explanation:
Since triangle PRS is congruent to triangle CFH,
PS = CH = 39
2x - 7 = 39
2x = 46
x = 23
Angle PRS = Angle CFH = 90°
13y - 1 = 90
13y = 91
y = 7
Sum of angles in a triangle add up to 180°.
Angle CHF = 180 - 90 - 28 = 62°
6z - 4 = 62
6z = 66
z = 11

Write a two-column proof to prove that vertical angles are congruent.
Answers
The manipulatives and paragraph forms are the two-column proof to prove that vertical angles are congruent.
Using manipulatives: Draw the same two intersecting lines on the paper. Then, fold the paper along the line via the joint. The fold bisects the other two borders, but only the lines of the folded border which are on top of each other are required. The edges check and lie straight on top of each separately. This folding procedure can be utilized with two vertical corners. As a result, the vertical angles are the same.
Paragraph Form: When ∠1 and ∠3 are connected to ∠2, they form a linear pair. This indicates that whether added dimension ∠2 to dimension ∠1 or dimension ∠2 to dimension ∠3, the total is 180°. That is, the measures of 1 and 3 are equal to the sum left before adding ∠2. As a result, the angles are the same. This argument applies to all pairs of vertical angles.

Jamal hypothesized that when adding two unit fractions together, he can determine the numerator by adding the two denomimators together, thrn could find the new denominator by multiplying the old denominators together. Prove jamal correct. What are some drawbacjs of jamals shortcut?
Answers
Jamal is correct ( ½+⅓ =⅚), when he says that when adding two unit fractions, the numerator is found by adding the denominators, and the new denominator can be found by multiplying the previous denominators.
State what is denominator with example?A denominator is the lowest number in a fraction that indicates how many equal parts are divided into a whole. It is a fraction's divisor. In this case, the denominator is 4, thus there are four components overall.
What is an illustration of a numerator?In a fraction, the number above the line is the numerator. For instance, the numerator of the fraction 3/5 is 3. A fraction's numerator displays the number of pieces that make up the whole while the denominator.
Adding 2 unit fractions example ½ and ⅓
By Jamal’s theory, 2+3=5
2*3=6
½+⅓ =⅚
Hence the theory is proved right.

Answers
The equation of a circle that has a radius of 9 and a center at (-2, 7) is the option;
(x + 2)² + (y - 7)² = 81What is the definition of a circle?A circle is a set that comprises all points that are equidistant from a point on a plane
The general form of the equation of a circle is; x² + y² + 2•g•x + 2•f•y + c = 0
The equation of a circle can also be presented in standard form as follows;
(x - h)² + (y - k)² = r²Where;
(h, k) = The coordinates of the center of the circle
r = The measure of the length of the radius of the circle
The given parameters are;
The radius of the circle, r = 9
Taking the coordinates of the center of the circle, (h, k) = (-2, 7)
The equation of the circle in standard form is therefore obtained by plugging in the values of h, k, and r as follows;
(x - h)² + (y - k)² = r²
Which gives;
(x - (-2))² + (y - 7)² = 9²
Which gives;
(x + 2)² + (y - 7)² = 9² = 81

Not all possible values of the domain may be covered by an operation's definition. For instance, it is impossible to square the roots of negative numbers or divide by zero in real numbers. An operation's domain of definition, also known as the active domain, is the set of values for which the operation is specified. However, the set of real values obtained by the operation is its codomain of definition, active codomain, image, or range. The set that contains the values created is referred to as the codomain. For instance, only non-negative numbers are produced by the squaring operation when applied to the real numbers; the set of real numbers is the codomain, but the non-negative numbers are the range.

Position of 1083 is 19 in the sequence that is the first one with a value greater than 1000.
What is Sequence?
A list of numbers or objects in a special order is called sequence.
Given that;
The nth term of a sequence = 3n²
Now,
Let [tex]a_{n}[/tex] be the nth term.
Then, [tex]a_{n} = 3n^{2}[/tex]
Let m be the term which is the first term with a value greater than 1000.
Then, [tex]a_{m} > 1000[/tex]
Substituted the value of [tex]a_{m}[/tex] we get;
3m² > 1000
Divide by 3 we get;
m² > 1000/3
m² > 333.333
Take square root both side;
m > √333.33
m > 18.25
Thus, m = 19
So, 19th term is the first one with a value greater than 1000.
Hence, [tex]a_{19} = 3(19)^2 = 3 * 361 = 1083[/tex]

Pointss!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Step-by-step explanation:
always remember (for your life) : the sum of all angles in a triangle is always 180°.
and the sum of all angles around a single point on one side of a line is also always 180°.
so,
180 = 65 + 51 + angle PSR
angle PSR = 180 - 65 - 51 = 64°
angle PST is the supplementary angle to angle PSR (that means together they have 180°), because of the principle of all angles around a single point (S) on one side of a line (TSR).
so,
180 = angle PST + angle PSR = angle PST + 64

For both triangles to be proven to be similar to each other by the SAS similarity theorem, it also needs to be shown that: A. angle N ≅ angle Z.
What is the Side-angle-side Similarity Theorem (SAS)?The side-angle-side similarity theorem (SAS) states that two triangles can be proven to be similar to each other if two pairs of corresponding sides of the two triangles are proportional to each other and one pair of corresponding angles of the two triangles are congruent to each other.
In the image given, we know that in both triangles:
XZ/LN = 6/2 = 3
ZY/NM = 9/3 = 3
Therefore:
XZ/LN = ZY/NM = 3
This means that the two triangles have two pairs of corresponding sides that are proportional to each other.
Thus, we also need to show that both triangles have a pair of congruent included angles before we can prove both triangles are similar to each other.
Thus, what needs to be shown is: A. angle N ≅ angle Z.
