1) The required volume of cement is 7.68 m3.
2) The costs will be $ 6,800, and the company's statement about approximate costs is correct.
1) Given that a rectangular garden 30m by 20m consists of a lawn 28m by 18m surrounded by a path, and the path is to be made of concrete to a depth of 8cm, to calculate the volume of cement required in m3 the following calculation must be performed :
8cm = 0.08mPath area x 0.08 = Volume((30 x 20) - (28 x 18)) x 0.08 = X(600 - 504) x 0.8 = X96 x 0.08 = X7.68 = XTherefore, the required volume of cement is 7.68 m3.
2) Given that the cement is delivered in bags each holding 1 cubic meter, to calculate the cost if the cement costs $ 600 per bag and the labor charges are $ 2000 and determine, if the company states that the cost will be approximately $ 70 per square meter, if this statement is correct, the following calculations should be performed:
7.68 m3 = 8 bags (8 x 600) + 2000 = X 6800 = X
Therefore, the costs will be $ 6,800.
6800/96 = 70.833
Thus, the company's statement about approximate costs is correct.

Answer:
Okay so for number 16
You have 2 parralel lines with a line through it.
Your trying to find the value of x
You have 2 angles given to you
one is 120 degrees whole the other is 5x+140 degrees.
They are corresponding angles. And now in this case corresponding angles are always equal.
So really all you gotta do is
120=5x+140
Now solve
-20=5x
x= -4
So the first one is x=-4
I can’t really see the other ones but here’s all you need to know
Alternate exterior - Equal
Altenrate interior - Equal
Corresponding - Equal
Interior - Not equal
Exterior-Not equal

The composition of function f ( x ) / g ( x ) = -x² + x - 1
What is Composition of functions?Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the first function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x⁴ - x³ + x²
Let the second function be represented as g ( x )
Now , the value of g ( x ) is
g ( x ) = -x²
Now , the composition of function is ( f/g ) ( x )
On simplifying , we get
( f/g ) ( x ) = f ( x ) / g ( x )
f ( x ) / g ( x ) = x⁴ - x³ + x² / -x²
f ( x ) / g ( x ) = -x² + x - 1
Hence , the function is A = -x² + x - 1

Convert each fraction to its equivalent using the least common denominator.
1/3 1/4
I am, honestly, slightly confused by the question wording, so here is what I think you need! :D
We can start by listing multiplies for each:
3:
3, 6, 9, 12, 15, 18, etc
4:
4, 8, 12, 16, 20, 24, etct
We can see that the least common denominator will be 12.
Answer:
[tex]\frac{1}{3}=\frac{x}{12}=\frac{4}{12}[/tex]
[tex]\frac{1}{4} =\frac{x}{12} =\frac{3}{12}[/tex]
If you need to multiply them:
[tex]\frac{4}{12} *\frac{3}{12} = \frac{12}{144} = \frac{1}{12}[/tex]
But you do not need to use a least common denominator for multiplying and can go straight to this:
[tex]\frac{1}{3} *\frac{1}{4} =\frac{1}{12}[/tex]
Hope this helps, have a nice day!

Answer:
81
Step-by-step explanation:
Here, some steps to evaluate (-9)².
