Answer:
Where's the question???????
Employees of landscaping companies built a retaining wall. They used brick to make the top 2/3 of the wall.
250 POINTS
Part A: What is the height of the brick proportion of the wall? Write an equation
Part B: Estimate the area of the whole retaining wall. A= LxW
For part c you need a equation
Part C: What is the area of the whole retaining wall? Write an equation to show your work. Compare your answer to your estimate to see whether your answer is reasonable
Answer with Step-by-step explanation:
a) 2 3/4 ÷ 3 = 11/12 feet
11/12 + 11/12 = 1 5/6
Or, you could write an algebraic equation:
2 3/4 ÷ 3 = x. (3x = 2 3/4)
x = 11/12
The height of the brick proportion of the wall is 1 5/6
b)
You know that 8 x 2 is 16. Well, you already know that the whole total of fractions, multiplied together, would probably be less that 1 and less than 1/2.
So, your rounded answer should be 16. Or 16 1/2
c)
Area = 8 1/2 x 2 3/4.
Use Distributive Property to solve the area.
(8 x 2) + (3/4 x 1/2) = x
8 x 2 = 16
3/4 x 1/2 = 3/8
16 + 3/8 = 16 3/8
x = 16 3/8
I think my answer is reasonable because I estimated 16, and 1/2. 3/8 is close to 1/2. That's why my answer is reasonable.

1) Which set of equations shows a way to find 729 : 9? 721 : 7 = 103 8: 2 - 4 . 729 : 3 = 243 729 ; 3= 243 So, 729 : 9 = 103 + 4 So, 729 : 9 = 243 + 243 720 : 9 = 80 9 : 9 = 1 72 :9= 8 9:9=1 So, 729 : 9 = 80 +1 So, 729=9= 8+1
Answer:
729 : 9 = 80 +1 is correct
Which of the following best describes the relationship shown in the equation below?
A.
It cannot be determined if this is or is not a functional relationship.
B.
This is a functional relationship.
C.
This is not a functional relationship.
Answer:
C. this is not a functional relationship.
Step-by-step explanation:
In other words, for each x-value, there is only one corresponding y-value.
For the equation x2 + y2 = 10, find the y-value for a given x-value.
Let x = 1.
Since (-3) · (-3) = 9 and 3 · 3 = 9, there are two y-values for x = 1.

#1
x=46°(Opposite interior angles)#2
[tex]\\ \sf\longmapsto x+68=180\implies x=180-68=112°[/tex]
#3
x=111°(Corresponding interior angles)#4
x=37°(Opposite angles)#5
x=58°(Opposite interior angles)#6
x=175°(Corresponding interior angles)#7
x=25°(Corresponding interior angles)Answer:
Hey there,
(1) x = 46° ( Alternative angles are equal)
(2) x + 68 = 180 ( Interior angles are added up to 180° )
x = 112°
(3) x = 111° ( Corresponding angles are equal)
(4) x = 37° ( Opposite angles are equal )
(5) x = 58° ( Alternative angles are equal )
(6) x = 175° ( Corresponding angles are equal )
(7) x = 26° ( Corresponding angles are equal )

How can we tell that 4:1 and 12:3 are equivalent ratios?
Answer:
We can tell that 4:1 and 12:3 are equivalent ratios because if you simplify 12:3 you will get 4:1. You can also multiply 3 to both sides of 4:1 and you will get 12:3. You can also do this with other numbers.
