sarahs volleyball team won 12 games of their first 18 games. if the continue to win at this rate, how many games will they lose if they play 36 games
Answer:
They lost 12 games.
Step-by-step explanation:
Set up a proportion.
12/18 = x/36
36 x 12 = 432
432/18 = 24
Because 18 represents how many games they won, the 24 also represents how many games they won. Therefore, you must subtract to find the amount of times that they lost.
36 - 24 = 12
Answer:
they lost 12 games

How do you graph square roots
Answer: Simplify the number in the square root.
Step-by-step explanation: For example, √25 can be simplified to 5 because half of 25 is 5. If x=5, graph this on the x-axis or horizontal line on the graph. Another example, √2 can be simplified to approximately 1.414. To graph this, you can use a graphing tool for accurate representation, or create a graph and place a dot right before 1.5 (in between 1 and 2).
What is the equation of the line that passes through the points (-3,2) and (-5,8)
Answer:
y = -3x - 7
Step-by-step explanation:
Slope = (8 - 2)/(-5 + 3) = 6/-2 = -3
Equation
y - 2 = - 3(x + 3)
y - 2 = -3x - 9
y = -3x - 7
Answer
y=-3x-7
is the equation of line that passes through the points (-3,2) and (-5,8)
step by step explanation:
we are given
(x1,y1)=(-3,2)
(x2,y2)=(-5,8)
formula of slope
m=(y2-y1 )/ (x2-x1)
putting value in formula
m=(8-2) /-5-(-3)
m=6/-5+3
m=6/-2
m=-3
Formula of line slop form of equation is
y-y1=m(x-x1)
putting the values in the formula
y-2= -3(x-(-3))
y-2= -3(x+3)
y-2=-3x-9
y=-3x-9+2
y=-3x-7
is the equation of line that passes through the points (-3,2) and (-5,8)
A line passes through (3, -2) and (6, 2). a. Write an equation for the line in point-slope form. b. Rewrite the equation in standard form using integers
Answer:
(a)
Given: A line passes through the points (3, -2) and (6, 2)
Point slope form: An equation of line passing through two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is given by:
[tex]y -y_1=m(x-x_1`)[/tex] .....[1] where m is the slope of the line.
Calculate first the slope of the line:
Slope(m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute the given points;
[tex]m = \frac{2-(-2)}{6-3}=\frac{2+2}{3} =\frac{4}{3}[/tex]
Substitute the value of m in [1] ;
[tex]y - (-2) = \frac{4}{3}(x-3)[/tex]
[tex]y+2=\frac{4}{3}(x-3)[/tex] ......[1]
therefore, the equation of line in point slope form is, [tex]y+2=\frac{4}{3}(x-3)[/tex]
(b)
to find the standard form of the equation [1]
Multiply both sides by 3 in [1] we get;
[tex]3(y+2) = 4(x-3)[/tex]
using distributive property; [tex]a\cdot (b+c) = a\cdot b + a\cdot c[/tex]
3y + 6 = 4x -12
Subtract 3y to both sides we get;
3y + 6 -3y = 4x - 12 - 3y
Simplify:
6 = 4x - 3y -12
Subtract 6 from both sides we get;
0 = 4x - 3y -12-6
Simplify:
4x - 3y - 18 =0
Therefore, the standard form of the equation is; 4x - 3y - 18 =0

Find the measure of angle x in the diagram below.
A. 25°
B. 45°
C. 105°
D. 145°
Answer:
C. 105°
Step-by-step explanation:
To find the answer, we can use the method of exterior angle of triangles, which would be <A + <B = <C, in which A and B is any interior angles of triangles and C would be the exterior angle for the remaining angle.
In this case:
45°+60° = 105°
Therefore the answer is C. 105°
Hope it helps!
The measure of the angle x is 105 degrees option (C) is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have a triangle shown in the picture.
As we know,
The sum of two interior angles is equal to the exterior angle;
The measure of the angle x:
x = 60 + 45
x = 105 degrees
Thus, the measure of the angle x is 105 degrees option (C) is correct.

Threeangles of a quadrilateral are equal and its fourth angel is 120° . Find all the angels
Answer:
80°
Step-by-step explanation:
Three angles are equal
Let the equal angle be x
3x+120=360
3x=240
x=240/3
=80
Hence the three angles are 80∘
Answer:
Each of the three congruent angles has measure 80 deg. The fourth angle has measure 120 deg.
Step-by-step explanation:
The sum of the measures of the angles of an n-sided polygon is (n - 2)180.
A quadrilateral has 4 sides, so n = 4 in the formula above.
(n - 2)180 = (4 - 2)180 = 2(180) = 360
The sum of the measures of the angles of a quadrilateral is 360 degrees.
Three angles are congruent. Let the measures of the three congruent angles be x. The sum of the measures of the 3 angles is x + x + x = 3x.
The sum of the measures of the angles is 360 deg.
3x + 120 = 360
Subtract 120 from both sides.
3x = 240
Divide both sides by 3.
x = 80
Answer: Each of the three congruent angles has measure 80 deg. The fourth angle has measure 120 deg.

Step-by-step explanation:
Analyze the reflectional symmetry of the regular polygons. The square has -fold reflectional symmetry. The regular octagon has -fold reflectional symmetry.
Answer:
The square has 4-fold reflectional symmetry. The regular octagon has 8-fold symmetry.
Step-by-step explanation:
For a square,
There are two lines of symmetry along two diagonals and
two lines of symmetry along midpoints of two pairs of opposite sides.
Therefore, there are 4 lines of reflectional symmetry in total.
For a regular octagon,
There are four lines of symmetry along four diagonals and
four lines of symmetry along midpoints of four pairs of opposite sides.
Therefore, there are 8 lines of reflectional symmetry in total.
Final answer:
A square has 4-fold reflectional symmetry, while a regular octagon has 8-fold reflectional symmetry.
Explanation:
Reflectional symmetry refers to a property of a shape where it can be divided into two mirror-image halves. The -fold reflectional symmetry of a regular polygon refers to the number of lines of symmetry it possesses. A line of symmetry is an imaginary line that divides the shape into two equal halves that are mirror images of each other.
For example, a square has 4-fold reflectional symmetry because it has 4 lines of symmetry, dividing it into 4 equal halves. Each line of symmetry passes through the midpoints of opposite sides.
On the other hand, a regular octagon has 8-fold reflectional symmetry because it has 8 lines of symmetry, dividing it into 8 equal halves. Each line of symmetry passes through the midpoints of opposite sides or vertices.
the sum of two numbers is 17 and their difference is 29 what are the two numbers
Answer:
According to the question,
Numbers are : 23 and -6
The two numbers are -6 and 23.
To find the two numbers, we can set up a system of equations based on the given information. Let the two numbers be [tex]\( x \) and \( y \), where \( x > y \)[/tex]. According to the problem, we have:
1. The sum of the two numbers is 17:
[tex]\[ x + y = 17 \][/tex]
2. The difference between the two numbers is 29:
[tex]\[ x - y = 29 \][/tex]
Now, we can solve this system of equations. We can add the two equations together to eliminate [tex]\( y \)[/tex] :
[tex]\[ (x + y) + (x - y) = 17 + 29 \] \[ 2x = 46 \] \[ x = \frac{46}{2} \] \[ x = 23 \][/tex]
Now that we have the value of [tex]\( x \)[/tex], we can substitute it back into one of the original equations to find [tex]\( y \)[/tex]. Let's use the first equation:
[tex]\[ 23 + y = 17 \] \[ y = 17 - 23 \] \[ y = -6 \][/tex]
Therefore, the two numbers are 23 and -6.

Which reason justifies the statement below
“If CD = EF, then CD = EF”
A. Defintion of congruence B. Reflexie property C. Symmetric property D. Definition of midpoint
The reflexive property justifies the statement "If CD = EF, then CD = EF".
Explanation:The reason that justifies the statement "If CD = EF, then CD = EF" is the reflexive property.
The reflexive property states that any geometric shape or object is always equal to itself. In this case, CD is equal to itself, and EF is equal to itself, so if CD = EF, then CD will always be equal to EF.
Therefore, option B, the reflexive property, is the correct reason for the given statement.
