Answer:
a. h = A/w = 2 ³/₄ ft
b. A'/A = 2/3
Step-by-step explanation:
a. What is the total height of the wall? Write an equation to represent the situation. Then solve.
The wall is a rectangle and its area is A = wh where w = width and h = height of wall.
Making h subject of the formula,
h = A/w
Now, Since the area of the retaining wall, A is 23 ³/₈ ft² and its width is the length of the portion of the wall which is brick w is 8 ¹/₂ ft, then
h = A/w
= 23 ³/₈ ft² ÷ 8 ¹/₂ ft
= 187/8 ft² ÷ 17/2 ft
= 187/8 ft² × 2/17 ft
= 187/4 ft² × 1/17 ft
= 187/68 ft
= 2 ³/₄ ft
b. If the area of the brick portion of the wall is 15(7/12), what fraction of the wall is brick? Write an equation to show your work.
Since the area of the brick portion of the wall is A' = 15 ⁷/₁₂ ft² and the total are of the retaining wall is A = 23 ³/₈ ft²
The fraction of the wall that is brick = A'/A
= 15 ⁷/₁₂ ft² ÷ 23 ³/₈ ft²
= 187/12 ÷ 187/8
= 187/12 × 8/187
= 8/12
= 2/3
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.

Answer:
x < 7
Step-by-step explanation:
Flip the equation to make it easier: x - 6 < 1
Move 6 to the other side and change sign: x < 1 + 6
Do simple addition: x < 7
use trig to determine the value of x for the right triangle. Round answer to nearest tenth. Show work and explain
Answer:
15.4
Step-by-step explanation
From the diagram, we are given;
Adjacent = 12
Hypotenuse=x
Angle of elevation =39°
Using the SOH CAH TOA identity
Cos 39 = 12/x
x = 12/cos39
x = 13/0.7771
x = 15.44
Hence the value of x to nearest tenth is 15.4

Directions: Identify the rise, run, and slope of the line below.
Answer:
rise= -2 run= -4 slope= -1/2
Step-by-step explanation:
slope= rise/run
since rise=-2 and run=-4, slope=-2/4, but we have to simplify, so slope=-1/2
Brittany bought 14 seeds she can plant 3 in a row. How many rows can she plant? Brittany can plant _____ rows. How many seeds are left?
Answer:
about 5 rows
Step-by-step explanation:
14 divided by 3= 4.7 but since you can’t have 4.7 rows I rounded it to 5 rows. You can’t have 4 rows because then there would be 2 seeds remainin.
Answer:
Brittany can plant 4 rows and she will have 2 seeds left
Step-by-step explanation:
Fourteen divided by 3 will give you a mixed fraction.
So you can do 3*4= 12
If you do 14-12 you will get 2 seeds that remain.

The answer is 15.7.
Step-by-step explanation:
How do you solve this? Please helppp what’s the answer???
Answer:
I won't be able to give you a numerical answer but that's not what your question's asking anyway. Just put a dot at the coordinates (0,-3) and one at (-2,3) and connect them. That's your first line. For the second question put a dot at the intersections (0,1) and one at (-4,-3) and connect them. You should be able to find a point where the two lines intersect. That's the point you need. If you still can't find it, then continue the lines or message me at riztofu on insta. I'll solve your question then.

The dimensions of a trapezoid are shown below. Which equation could you use to find the Area of the Trapezoid?
Answer:
See Explanation
Step-by-step explanation:
No trapezoid is attached; so, I will solve on a general note
The area of a trapezoid is:
[tex]Area = \frac{1}{2}(Sum\ of\ parallel\ sides) * Height[/tex]
Using the attached image as a point of reference;
The parallel sides are: AD (6cm) and BD (12cm)
The height is 4cm
So, the area is:
[tex]Area = \frac{1}{2} * (6cm + 12cm) * 4cm[/tex]
[tex]Area = 18cm * 2cm[/tex]
[tex]Area = 36cm^2[/tex]
Find the measure of the angle indicated in bold
Answer:
x=5
Step-by-step explanation:
hey there
the angles given are corresponding angles meaning that they are congruent
so we set up an equation
23x-5=21x+5
step 1 subtract each side by 5
5-5 cancels out
-5-5=-10
now we have
23x-10=21x
step 2 subtract each side by 23x
21x-23x=-2x
now we have
-2x=-10
step 3 divide each side by 2
-10/-2=5
so we can conclude that
x=5
