Step-by-step explanation:
Given
Circumference of circle = 48.042 yards
diameter (d) = ?
we know
Circumference = πd
or, 48.042 = 3.14 * d
or, d = 48.042 / 3.14
Therefore d = 15.3 yards
The circle's diameter is 15.3 yards.
Hope it will help :)❤
A rectangular schoolyard is to be fenced in using the wall of the school for one side and 500 meters of fencing for the other three sides. The area in square meters of the schoolyard is a function of the length in meters of each of the sides perpendicular to the school wall.
A. Write an expression for A(x) using NO SPACES.
B. What is the area of the schoolyard when x = 100 ?
C. What is a reasonable domain for x in this context?
Answer:
StPart 1) The expression is
Part 2) The area of the schoolyard when x=40 m is A=2,800 m^2
Part 3) The domain is all real numbers greater than zero and less than 75 meters
Step-by-step explanation:
Part 1) Write an expression for A(x)
Let
x -----> the length of the rectangular schoolyard
y ---> the width of the rectangular schoolyard
we know that
The perimeter of the fencing (using the wall of the school for one side) is
so
-----> equation A
The area of the rectangular schoolyard is
---> equation B
substitute equation A in equation B
Convert to function notation
Part 2) What is the area of the schoolyard when x=40?
For x=40 m
substitute in the expression of Part 1) and solve for A
Part 3) What is a reasonable domain for A(x) in this context
we know that
A represent the area of the rectangular schoolyard
x represent the length of of the rectangular schoolyard
we have
This is a vertical parabola open downward
The vertex is a maximum
The x-coordinate of the vertex represent the length for the maximum area
The y-coordinate of the vertex represent the maximum area
The vertex is the point (37.5, 2812.5)
using a graphing tool, see the attached figure
therefore
The maximum area is 2,812.5 m^2
The x-intercepts are x=0 m and x=75 m
The domain for A is the interval -----> (0, 75)
All real numbers greater than zero and less than 75 meters

Answer:
2, 3, ,6 ,9. (YOUR ANSWER)
All numbers listed below!
15282 ÷ 1 = 15282
15282 ÷ 2 = 7641
15282 ÷ 3 = 5094
15282 ÷ 6 = 2547
15282 ÷ 9 = 1698
15282 ÷ 18 = 849
15282 ÷ 27 = 566
15282 ÷ 54 = 283
15282 ÷ 283 = 54
15282 ÷ 566 = 27
15282 ÷ 849 = 18
15282 ÷ 1698 = 9
15282 ÷ 2547 = 6
15282 ÷ 5094 = 3
15282 ÷ 7641 = 2
15282 ÷ 15282 = 1

You have a rectangular prism as shown below. Its height is 7 cm, its width is 4 cm, the length is 3 cm. How would we calculate this volume?
9514 1404 393
Answer:
84 cm³
Step-by-step explanation:
There are formulas for the volumes of simple geometric solids: prism, cylinder, pyramid, cone, frustum of a pyramid or cone.
The formula for the volume of a rectangular prism is ...
V = LWH . . . . . product of Length, Width, and Height
Put the numbers in place of the corresponding variables and do the arithmetic.
V = (3 cm)(4 cm)(7 cm) = 84 cm³
The volume of this rectangular prism is 84 cubic centimeters.

The product of a rational and irretional number is always, sometime, or never rational.
Answer:
Step-by-step explanation:
The product of a rational number and an irrational number is SOMETIMES irrational." If you multiply any irrational number by the rational number zero, the result will be zero, which is rational. Any other situation, however, of a rational times an irrational will be irrational.

Colin types his research paper for 3 hours. how many minutes is that?
Answer:
180 minutes
Step-by-step explanation:
60*3=180
Hey there! The answer is:
180 minutes
Explanation:
There are 60 minutes in 1 hour. We know Colin typed his research paper for 3 hours. This means we can multiply 60 minutes by 3 hours and that will give us the number of minutes he spent researching his paper.
60 x 3 = 180
This means Colin typed his research paper for 180 minutes. I hope this answer helped you out, have an amazing day :)

Answer:
There is no solution.
Step-by-step explanation:
In simplifying this, you'd start by distributing the negative sign on the left.
-(6x + 6) + 2 = -6x - 3 becomes -6x - 6 + 2 = -6x - 3.
Then you can add -6 and 2 on the left.
-6x - 6 + 2 = -6x - 3 becomes -6x - 4 = -6x - 3.
With that done, you can add 4 to both sides.
-6x - 4 = -6x - 3 becomes -6x = -6x + 1.
Then, add 6x to both sides.
-6x = -6x + 1 becomes 0 = 1.
Here, we run into an issue - 0 does not equal 1, and there is no way to avoid running into this while solving this equation. This means that this problem has no solution, there is no value that x can have that would make it true.
Solve: 2x+1= 2X - 1
A) No Solution
B) x = 0
C) Infinitely Many Solutions
Answer:
A) No Solution
Step-by-step explanation:
2x+1=2x-12x-2x=-1-10 = -2Thus, it has no solution
