What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
Given
Madeline has to earn at least 80 points for her science fair project. So far on the rubric she has 64 points.
so,
Total = 80 (at least)
accumulated = 64
Required
Express as an inequality
In inequalities, at least means ≥
So, the expression is:
Where x represents the additional points
x + 64 ≥ 80
Solve for x
x ≥ 16
Hence, she needs at least 16 points.

Which 3 relationships are true in the construction below?
Answer:
The correct options are;
Line CD is the perpendicular bisector of line AB
Line segment AB is perpendicular to line CD
Line segment AE is congruent to line segment BE
Step-by-step explanation:
From the construction, we have that the radius of circle A is equal to the radius of circle A as the circumference of circle A passes through the center of circle A
Therefore, the construction is the bisection of line segment AB by the construction of the perpendicular bisector CD, from which we have line segment AE is congruent to line segment BE and line segment AB is perpendicular to line CD

Find the digits in space given with the following numbers so that the number is divisible by 11.

b) 37__45
Answer:
A
Step-by-step explanation:
I am not sure but I think A
Answer:
a) 22583
b) 37345
Step-by-step explanation:
Divisibility by 11
Rule: A number passes the test for 11 if the difference of the sums of alternating digits is divisible by 11.
For example, the number 14982 is divisible by 11. Sum the digits
1+9+2=12
4+8=12
Subtract them: 12-12=0. Since 0 is divisible by 11, then the number also is.
The number 745102 is not divisible by 11:
7+5+0=12
4+1+2=7
12-7=5. 5 is not divisible by 11.
a) 2_583. Let's call X to the unknown digit 2X583
2+5+3=10
X+8 should be 10 or 21, so 10-10=0 or 21-10=11 are divisible by 11, but X cannot be greater than 9, thus
X+8=10 => X=2. The number is 22583
b) 37X45
4+7=11
3+X+5 should be 11 or 21. Again, X must be less than 10, thus
3+X+5=11 => X=3. The number is 37345

Answer:
132
Step-by-step explanation:
Answer: 132 lb
Step-by-step explanation:
Observe the pattern here:
20 lbs * 200 = 4000 ft
50 lbs * 200 = 10,000 ft
Notice the pattern here?
Each lb covers 200 ft.
You can use this same method to find the answer.
? * 200 = 26,400 ft
Dividing by 200 on both sides, you’ll find that the answer is 132 lb.
Given mn, find the value of x.
The value of the angle x in the given set of parallel lines is 62°.
Given that are two lines m and n which are parallel to each other, a transversal line t intersecting the lines at one point each making angles measuring 118° and x, which are opposite to each other, x is on line n whereas 118° is on m,
We need to find the value of x,
Here, we can use the property of corresponding angles to find the value of x.
Corresponding angles are formed when a transversal intersects two parallel lines, and they are congruent (equal) to each other.
In this case, the corresponding angle to the 118° angle on line m is the supplement of angle x on line n.
Since the corresponding angles are equal, we can set up the equation:
180° - x = 118°
x = 62°
Hence the value of x is 62°.

Answer:
Step-by-step explanation:
given: (2,1) & (5-8)
first find the slope,
m= (Y2-Y1) / (X2-X1)
m=(-8-1)/(5-2)
m=(-9)/(3)
m=-3
we have y=-3x+b
use any point to sub in x and y
1=-3(2)+b
1+6=b
b=7 therefore, y=-3x+7 is the equation
Answer:
y = - 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (5, - 8)
m = [tex]\frac{-8-1}{5-2}[/tex] = [tex]\frac{-9}{3}[/tex] = - 3 , then
y = - 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 1 ), then
1 = - 6 + c ⇒ c = 1 + 6 = 7
y = - 3x + 7 ← equation of line

Answer: 4/5 (B)
Step-by-step explanation:
The ratio is 5/9 represents the number of students who prefer soccer to the total number of students in Arturo’s class
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
To determine the ratio represents the number of students who prefer soccer to the total number of students in Arturo’s class
Here the number of students who prefer soccer = 20
The total number of students in Arturo’s class = 20 + 16 = 36
According to the given situation, the required ratio is written as:
The required ratio = students who prefer soccer / total number of students
The required ratio = 20 / 36
Convert the above fraction into the simplest form
The required ratio = 5/9
Therefore, the ratio is 5/9 represents the number of students who prefer soccer to the total number of students in Arturo’s class

A triangle has sides of length 2 cm, 8 cm and 9 cm.
Calculate the value of the largest angle in this triangle.
:)
Answer:
113.97 degrees
Step-by-step explanation:
use the cosine rule for finding an angle
cosA = b^2 + c^2 - a^2
2bc
In the given triangle angle A is greatest than any other angle.
What is the triangle?A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
Given sides of triangle, a=2cm,b=8cm,c=9cm
cosine law
Cos A = [tex]\frac{-a^2 + b^2 + c^2}{ 2bc}[/tex] = [tex]\frac{64 + 81 - 4 }{2 * 8 *9}[/tex] = 141/ 144
Cos B = [tex]\frac{a^2 - b^2 + c^2}{ 2ac}[/tex] = [tex]\frac{4 + 81 - 64}{2 * 2 *9}[/tex] = 21/36
Cos C = [tex]\frac{a^2 + b^2 - c^2}{ 2ab}[/tex] = [tex]\frac{4 + 64 -81}{2 * 2* 8}[/tex] = -13/52
A = Cos⁻¹ (141 /144 )
B = Cos⁻¹ (21/ 36 )
C = Cos⁻¹ (-13/52 )
Thus Angle A < Angle B < Angle C.
Therefore, Angle A is the greatest in the triangle.

In the isosceles trapezoid, m∠S=68∘ .
What is m∠Q ?
9514 1404 393
Answer:
112°
Step-by-step explanation:
Same-side angles of a trapezoid are supplementary.
m∠P = 180° - m∠S = 180° -68° = 112°
The angles of an isosceles trapezoid match their symmetrical counterparts.
m∠Q = m∠P
m∠Q = 112°

The measure of an angle is nine times the measure of its supplementary angle. What is the
measure of each angle
Answer:
The measure of the angle is 150°, the measure of its supplementary is 30°
Step-by-step explanation:
The given parameters are;
The measure of the given angle = 5 × The measure of its supplementary angle
Let "x" represent the given angle, and let "y" represent its supplementary angle, we have;
x = 5 × y...(1)
x + y = 180°...(2)
By substituting the value of x = 5 × y, from the first equation into the second equation, we have;
x + y = 180°
x + y = 5 × y + y = 5·y + y = 6·y = 180°
y = 180°/6 = 30°
y = 30°
x = 5 × y = 5 × 30° = 150°
x = 150°
The measure of the angle = x = 150°, the measure of its supplementary = y = 30°.

Answer:

Step-by-step explanation:
Given: m∠AEB = 45°
∠AEC is a right angle.
Prove: Ray E B bisects ∠AEC.
3 lines extend from point E. A horizontal line extends to the left to point A and a vertical line extends up to point C. Another line extends halfway between the other 2 lines to point B. Lines A E and E C form a right angle.
Proof:
We are given that m∠AEB = 45° and ∠AEC is a right angle. The measure of ∠AEC is 90° by the definition of a right angle. Applying the ______________
gives m∠AEB + m∠BEC = m∠AEC. Applying the substitution property gives 45° + m∠BEC = 90°. The subtraction property can be used to find m∠BEC = 45°, so ∠BEC ≅ ∠AEB because they have the same measure. Since Ray E B divides ∠AEC into two congruent angles, it is the angle bisector.

Step-by-step explanation:
(3x - 40)° and (2x - 10)° are vertical angles, so they will always be the same
1.) 30
3x - 40 = 2x - 10
3x - 2x = 40 - 10
x = 30
2.) 15
(6y - 10)° + (6y + 10)° = 180°
6y + 6y + 10 - 10 = 180
12y = 180
