The volume of concrete that was used to pour the sidewalk is 270 cubic meters and this can be determined by using the formula of volume.
Given :
A sidewalk is 15cm high, 30m wide, and 60m long.
The following steps can be used in order to determine the volume of concrete that was used to pour the sidewalk:
Step 1 - The formula of volume can be used in order to determine the volume of concrete that was used to pour the sidewalk.
Step 2 - The formula of volume is given below:
[tex]\rm V = L\times W \times H[/tex]
where L is the length, W is the width, and H is the height.
Step 3 - Now, substitute the values of the known terms in the above formula.
[tex]\rm V = 60\times 30 \times \dfrac{15}{100}[/tex]
Step 4 - Simplify the above expression.
V = 270 cubic meters
Therefore, the correct option is A).

Which statement is true about the equation in the box?
x + 9 - 4x = -3x - 3
A. There is only 1 solution, and x = -3.
B. There is only 1 solution, and x = 9.
C. There are infinitely many solutions because the variables cancel each other.
D. There is no solution because 9 ≠ -3.
Answer:
D. There is no solution because 9 ≠ -3.
Step-by-step explanation:
For finding out the statement let's check it ourselves
x + 9 - 4x = - 3x - 3
-3x + 9 = - 3x - 3
9 ≠ - 3
So there is no solution for the equation.

.. What is the value of this expression? 6 + (-9) - (-5) i need help on my test can u guys help me and no links because the links u guys give me dont work(no disrespect)
Answer:
-8
Step-by-step explanation:
What is the value of this expression? 6 + (-9) - (-5)
6 + (-9) - (-5)
= 6 - 9 + 5
Following the rules of BODMAS, addition comes first before subtraction
= 6 - 14
= - 8
6 + (-9) - (-5) = -8
Note:
- * - = +
- * + = -
+ * - = -
+ * + = +

Which linear function is graphed on the grid?
a - g(x) = 2/15x - 6
b - g(x) = 2/15x + 45
c - g(x) = 15/2x - 6
d - g(x) = 15/2x + 45
Answer:
G(x)=2/15x-6
Step-by-step explanation:
The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
x/a + y/b = 1
Where 'a' is the x-intercept of the line and ‘b’ is the y-intercept of the line.
From the graph, the x-intercept is - 6, and the y-intercept is 45. Then the equation is given as,
x/(-6) + y/45 = 1
- 15x + 2y = 90
y = (15/2) x + 45
g(x) = (15/2) x + 45
The linear function graphed on the grid will be g(x) = (15/2) x + 45. Then the correct option is D.

Which ratio is smaller, 32 : 24 or 30 : 22?
Answer:
32 : 24 is smaller
Step-by-step explanation:
32 : 24 = 32/56, reduced is 4/7
30 : 22 = 30/52, reduced is 15/26
a common denominator is 182:
4/7 = 104/182
15/26 = 105/182

Omar is planning to buy some new baseball shoes. He has already saved $22.50 The shoes cost at least $38 dollars. He writes an inequality to determine how much more he will need to save
Answer:
At least $15.50
Step-by-step explanation:
Omar is planning to buy some new baseball shoes. He has already saved $22.50
The shoes cost at least 38 dollars.
At least means, greater than or equal to which is represented by the sign
≥
The inequality is given as
22.50 + x ≥ 38
x ≥ 38 - 22.50
x ≥ 15.5
Therefore, he would need to save at least $15.50

Mark wants to round to the nearest hundred to estimate the sum of 271 and 582.
He wrote 270 + 580 = 850.
Part A
What mistake did Mark make?
A.
00:00
Mark should have rounded 271 to 250 and rounded 582 to 550: 250 + 550 = 800.
B.
00:00
Mark should have rounded 271 to 250 and rounded 582 to 600: 250 + 600 = 850.
C.
00:00
Mark should have rounded 271 to 300 and rounded 582 to 500: 300 + 500 = 800.
D.
00:00
Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 600 = 900.
00:00
Part B
What is the sum of 271 and 582 rounded to the nearest hundred?
A. 300
B. 850
C. 900
D. 1,000
Answer:
Step-by-step explanation:
Part A:
Mark did not round to the nearest hundreds, he rounded to the nearest tens.
Option A (Incorrect):
271 and 582 are normally not rounded down, unless we are using limits coming from the left and a unique equation.
Option B (Incorrect):
271 as the same problem as option A, but 582 rounding to 600 is correct. It doesn't make sense to round both numbers differently, unless stated.
Option C (Incorrect):
271 rounding to 300 is correct, but 582 is not normally rounded down to 500 unless we are using limits coming from the left and a unique equation. Unless stated, don't round both numbers differently.
Option D (Correct):
271 rounded to 300 and 582 rounded to 600 looks correct for rounding to the hundreds.
Part B:
There are two ways to solve this question:
One way:
271 + 582 = 853
Round 853 to the nearest hundred for 900
(Note: Round 853 to the nearest tens for 850.)
Second way:
271 + 582
Round Numbers:
300 + 600
= 900

Examine the system of equations. Which is an equivalent form of the first equation that when added to the second equation eliminates the y terms? Negative StartFraction 5 Over 8 EndFraction x + three-fourths y = 12 8 x + 12 y = 11
Answer:
10x - 12y = 192
Step-by-step explanation:
Given the equation :
-5/8x + 3/4y = 12 - - - (1)
8x + 12y = 11 ___(2)
The equivalent form of the first equation which can eliminate the y term :
Multiply (1) by - 16 :
-5/8x * - 16 + 3/4y * - 16 = 12 * - 16
10x - 12y = 192
Hence, Adding the obtained equation and equation(2) will eliminate.
