Answer:
9a) corresponding
9b) Congruent
9c) x=5
10) x=4
11=9
Step-by-step explanation:
9a. The angles are corresponding, as, if you look at the 8 angles as 2 groups of 4, they would be in the same spot.
b. Corresponding angles are congruent (by corresponding angles are congruent theorem)
c. Because the angles are congruent, we know that
23x-5=21x+5
23x-21x=5+5
2x=10
x=5
10. We know that (see attached photo) angle a is equal to angle b through the vertical angle theorem. Then, we know that angle b is equal to angle c through corresponding angles. So, we know that a=b, and b=c, so through the transitivity property, a=c, and c=90 degrees (it is a right angle)
Therefore, a=90 degrees
a=21x+6, so 21x+6=90
21x=84
x=4
11) This is almost the exact same problem as 10. We know that (see attached photo) a=b through vertical angles, and b=c through corresponding angles. Therefore, a=c
When you substitute the values of the two angles, we get:
-1+14x=12x+17
14x-12x=17+1
2x=18
x=9

The rectangle and the trapezoid have the same area. What is the length l of the rectangle?
l=
ft
Answers
The length 'l' of the rectangle will be;
⇒ l = 18 feet
What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The rectangle and the trapezoid have the same area.
Now,
Since, The rectangle and the trapezoid have the same area.
Hence, We get;
Area of rectangle = l × 9
And, Area of trapezoid = 1/2 (24 + 12 ) × 9
= 1/2 × 36 × 9
= 18 × 9
= 162
So, We get;
⇒ l × 9 = 162
⇒ l = 162/9
⇒ l = 18 feet
Thus, The length 'l' of the rectangle will be;
⇒ l = 18 feet

Step by step explanation:
The same art teacher estimates that he has enough clay for 9 students. Is he correct? Why?
Remember: He has 47 1/3 pounds of clay and wants to give each student 2 1/2 lbs of clay.
*Use compatible numbers to estimate. These are numbers that are close to the actual numbers that you know will divide easily.
Answers
Answer:
The art teacher is incorrect.
Step-by-step explanation:
Coming Up with Compatible Estimate Numbers:
The teacher has 47 1/3 pounds of clay. We can round this to 50. Now we have 50 pounds of clay.
Explaining the Operations:
The teacher wanted to distribute the clay by 2.5 lbs. This means we need to divide the amount of clay by 2.5.
Performing the Operations:
Divide 50 by 2.5 ---> 50÷2.5=(5÷2.5)*10--->5÷2.5=2--->2*10=20
Final Conclusion
For every student, the art teacher plans to give 2.5 lbs of clay. This means he will divide his 47 1/3 pounds by 2.5 piles and hand them out to the students. If we round 47 1/3 to 50 (about 2 points higher) and divide 50 by 2.5, you get 20. This means he would have a little less than enough clay for 20 students, not 9. Therefore, the art teacher is incorrect.
****ANOTHER POSSIBLE SOLUTION****
You can also multiply 9 x 2.5 and see if the product is close to 47 1/3. In this case, you can round 2.5 to 3 and proceed with the multiplication. 9*3=27 Since 27 is a lot lower than 47 1/3, the art teacher is incorrect.

4. Steven made punch by mixing 2.8 liters of orange juice, 0.75 liters of pineapple juice, and 1.2 liters of sparkling water. How many liters of punch did Steven make?
Answers
#1:
Serena does not have enough albums to hold all the photographs.
Work:
40*36 = 1440
#2:
A group of 1,058 people is called in for jury duty.
Work:
A jury is made up of 12 jurors and 2 alternates.
1 jury = 12 jurors + 2 alternates = 14 members
So, the number of complete juries that can be formed is
= 1058/14 = 75.57
#3:
Gary's backpack will weigh 7.8 pounds with the math and science textbooks in it.
Work:
Total weight = backpack weight + math textbook weight + science textbook weight
Total weight = 1.2 + 3.75 + 2.85
Total weight = 7.8 pounds
#4:
Steven made 4.75 liters of punch.
Work:
Liters of Punch = orange juice + pineapple juice + sparkling water
Liters of Punch = 2.8 + 0.75 + 1.2
Liters of Punch = 4.75

Answers
Answer: Non of the options is correct.
Step-by-step explanation:
Domain of a function are the minimum and maximum values of independent variable (x).
You are given the function:
f(x) = 4x – 8
The domain can be any real numbers.
Range is the minimum to maximum value of dependent variable ( y )
From the given equation:
f(x) = 4x – 8
If the value of domain are substituted, the range will also be any real numbers.
Non of the answers is correct because both the domain and the range are all real numbers.
But the best option among the given option is option A:
domain: {x | x is a real number}; range: {y | y > –8}

Step-by-step explanation:
A: 4-10=-6. -6=-n 6=n (negatives cancel)
B: 3*2=6 n=6
D: 48/8=6 n=6
∑ Hey, js1012201 ⊃
Answer:
(A) 4 = 10 - n
(B) 3 = n/2
(D) 8n = 48
Step-by-step explanation:
Given:
Select all the equations where n = 6 is a solution.
Choose 3 answers:
(A) 4 = 10 - n
(B) 3 = n/2
(C) 12 = n + 7
(D) 8n = 48
(E) 5 + n = 8
Solution:
Let's solve each answer choices to see where n = 6 is a solution:
-------------------------------------------------------------------------------------------------------------
(A) 4 = 10 - n
4 + n = 10 - n + n
4 + n = 10
4 + n -4 = 10 - 4
n = 6
(A) n = 6
-------------------------------------------------------------------------------------------------------------
(B) 3 = n/2
Multiply both sides by 2
2n/2 = 3 × 2
n = 6
(B) n = 6
-------------------------------------------------------------------------------------------------------------
(C) 12 = n + 7
Subtract both sides by 7
n + 7 -7 = 12 - 7
n = 5
(C) n = 5
-------------------------------------------------------------------------------------------------------------
(D) 8n = 48
Divide both sides by 8
8n/8 = 48/8
n = 6
(D) n = 6
-------------------------------------------------------------------------------------------------------------
(E) 5 + n = 8
Subtract 5 from both sides
5 - 5 + n = 8 - 5
n = 3
(E) n = 3

Answer: 4/5 = 180/b; b = 225 boys
Answer:
Given that there are 4 boys for every 5 girls, we can set up the following proportion:
4/5 = x/180
where x is the number of boys.
To solve for x, we can cross-multiply:
5x = 4 * 180
5x = 720
x = 144
Therefore, there are 144 boys.

write down the inequality shown on the number line.
Answers
Answer:
The inequality on the number line shown is {x:x<2}
The inequality shown on the number line is represented by the relation x<2.
As, the inequality on a number line, the notation includes the open circle at 2.
This means that the value of 2 itself is not included in the set of solutions.
In the notation "x < 2," the symbol "<" indicates "less than," and the number 2 is the upper bound of the inequality.
Since the inequality is strict, use an open circle to show that the point 2 is not part of the solution set.
Therefore, the inequality is "x < 2".

x = 7.5, y = 8.5-----------------------------------
The two angles with the variable x form a linear pair and therefore:
16x - 18 + 10x + 3 = 18026x - 15 = 18026x = 195x = 195/26x = 7.5Angles 16x - 18 and 12y are congruent as vertical angles:
16*7.5 - 18 = 12y102 = 12yy = 102/12y = 8.5Answer:
x = 7.5
y = 8.5
Step-by-step explanation:
Linear Pair
Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).
To find x, equate the sum of the two angles with the variable x to 180° and solve:
⇒ (16x - 18)° + (10x + 3)° = 180°
⇒ 16x - 18 + 10x + 3 = 180
⇒ 26x - 15 = 180
⇒ 26x = 195
⇒ x = 7.5
Vertical Angles Theorem
When two straight lines intersect, the opposite vertical angles are congruent.
Therefore:
⇒ (16x - 18)° = 12y°
Substitute the found value of x into the equation and solve for y:
⇒ 16x - 18 = 12y
⇒ 16(7.5) - 18 = 12y
⇒ 120 - 18 = 12y
⇒ 102 = 12y
⇒ y = 8.5
