Answer:
113.04 feet²
Step-by-step explanation:
Use the circle area formula, A = [tex]\pi[/tex]r²
Sine the diameter is 12 feet, the radius is 6 feet
Plug in 6 as r into the formula, and 3.14 as pi, then solve:
A = [tex]\pi[/tex]r²
A = (3.14)(6²)
A = (3.14)(36)
A = 113.04
So, the area of the circle is approximately 113.04 feet²

simplify (2x^2-32)/x^2+10+24
Answer:
Step-by-step explanation:
(2x^2-32)/(x^2 + 10x + 24) is less subject to misinterpretation. Write these factors in a vertical column:
(2x^2-32)
------------------------- and then factor numerator and denominator separately:
(x^2 + 10x + 24)
2(x^2 - 16) 2(x - 4)(x + 4) 2(x - 4)
--------------------- = --------------------- = ---------------- Note: This is good ONLY
(x + 4)(x + 6) (x + 4)(x + 6) x + 6 for x ≠ -4! Division by

The net of a cube is shown below. If the surface area of the net is 294 in^2 , then what is the length of each side of the cube?
Answer:
7 in
Step-by-step explanation:
294:6=49
[tex]\sqrt{49}=7 in[/tex]
The length of each side of the cube is 7 inches.
What is surface area of a cube?The surface area of the cube all six faces of the cube are made up of squares of the same dimensions then the total surface area of the cube will be the surface area of one face added six times to itself. The formula to find the surface area of a cube is 6a², where a is edge.
Given that, the surface area of a cube is 294 square inches.
Now, 6a²=294
a²=294/6
a²=49
a=7 inches
Therefore, the length of each side of the cube is 7 inches.

drawbridge at the entrance to an ancient castle is raised and lowered by a pair of chains. The figure represents the drawbridge when flat. Find the height of the suspension point of the chain, to the nearest tenth of a meter, and the measures of the acute angles the chain makes with the wall and the drawbridge, to the nearest degree.
Answer:
4.0 meters, ∠C = 39°, ∠A = 51°
Step-by-step explanation:
Firstly, our diagram shows us that the given triangle is actually a right triangle. So we can use the Pythagorean Theorem to solve for the height of the chain:
[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex](3.3)^{2} +b^{2} =(5.2)^{2}[/tex]
[tex]b^{2} =(5.2)^{2}-(3.3)^{2}[/tex]
[tex]b =\sqrt{(5.2)^{2}-(3.3)^{2}}[/tex]
[tex]b=4.0187...[/tex]
[tex]b=4.0 m[/tex]
Now, we can use the Law of Cosines to figure out one of the acute angles:
[tex]c^{2} =a^{2} +b^{2} -2ab(cos(C))[/tex]
[tex](3.3)^{2} =(4.0)^{2} +(5.2)^{2} -2(4.0)(5.2)(cos(C))[/tex]
[tex]cos(C)=\frac{(3.3)^{2}-(4.0)^{2} -(5.2)^{2}}{-2(4.0)(5.2)}[/tex]
[tex]C=cos^{-1}( \frac{(3.3)^{2}-(4.0)^{2} -(5.2)^{2}}{-2(4.0)(5.2)})[/tex]
[tex]C=39.3915...[/tex]
∠C = 39°
And since we know that all angles in a triangle add up to 180°:
∠A + ∠B + ∠C = 180
∠A + 90 + 39 = 180
∠A = 180 - 90 - 39
∠A = 51°
However, you should always review any answers on the Internet and make sure they are correct! Check my work to see if I made any mistakes!
Isaac used 1/4 of an ounce of nuts to make 1/8 of a cake. How many ounces of nuts are needed to make one cake?
Answer:
2 ounces of nuts are needed to make one cake.
Step-by-step explanation:
if he uses 1.4 to make 1/8 of a cake, then you need to do it 8 times to make a full cake. Multiply 1/4 * 8 which is equal to 8/4 which simplifies to 2. This is your answer!
2 ounces of nuts are needed to make one cake.

Answer:
x = 7
Step-by-step explanation:
The Triangle Sum Theorem tells us that the sum of the measures of a triangle's interior angles is 180. Using this information, we can make an equation to solve for x.
82 + 9x - 6 + 6x - 1 = 180
75 + 15x = 180 (Combine like terms)
15x = 105 (Subtract 75 from both sides)
x = 7 (Divide both sides by 15)
We can plug the value of x back into the equation to make sure of this answer.
Liu is making a rabbit pen. The graph shows where he plans to place it in his backyard. Each unit on the graph represents 1 foot.
1. What is the distance between points R and U? Explain how you found this distance.
2. Find the other three side lengths.
The length of the side between U and T is _______ feet.
The length of the side between T and S is _______ feet.
The length of the side between S and R is _______ feet.
3. The perimeter is the sum of the side lengths. What is the perimeter of the pen?
4. Does Liu have enough fence to make the pen? Why or why not?
Answer:
1. The distance between the points R and U is 4 feet
2. The length of the side between U and T is 3 feet
The length of the side between T and S is 4 feet
The length of the side between S and R is 3 feet
3.The perimeter of the pen is 14 feet
4. Yes
Liu has enough fence to make the Pen because he has more fence than the perimeter of the pen
Step-by-step explanation:
The 'x', and 'y' (x, y) coordinates of the points are;
R(5, 7), U(5, 3), S(8, 7), T(8, 3)
1. From the graph, the distance between the points R and U is given by the change in the values of the y-coordinate, given in feet, since the x-coordinate values are the same
Therefore, the distance between the points R and U = 7 ft. - 3 ft. = 4 ft.
2. Similarly, the length of the side between U and T is given by the change in the values of the x-coordinate, given in feet, since the y-coordinate values of U ant T are the same, as follows;
The length of the side between U and T = 8 ft. - 5 ft. = 3 ft.
Similarly the length of the side between T and S which have the same x-coordinate values is given as follows
The length of the side between T and S = 7 ft. - 3 ft. = 4 ft.
The length of the side between S and R which have the same y-coordinate values is given as follows;
The length of the side between S and R = 8ft. - 5ft. = 3ft.
3. The perimeter of the pen = Length R and U + Length U and T + Length T and S + Length S and R
∴ The perimeter of the pen = 4 ft. + 3 ft. + 4 ft. + 3 ft. = 14 ft.
4. The length of fencing Liu has = 16 feet (from internet source)
Therefore, the length of fence Liu has, 16 ft.is more than the length that make up the perimeter of the pen, 14 ft.
Therefore Liu has enough fence to make the Pen because the length of fence he has is more than the perimeter of the pen.

If the midpoints of the sides of ∆EFG shown below were connected with line segments, what would be the perimeter of the resulting triangle? Explain how you arrived at your answer. *
Answer:
17.5
Step-by-step explanation:
I beleive since we are connecting midpoints you divide each side by 2 and add them all up to get the perimeter of the smaller triangle made with the ratio of 1:2
The midpoints of the sides of ∆EFG are connected with line segments, then the perimeter of that triangle is 15.5 cm.
What is the triangle?Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
Given
If the midpoints of the sides of ∆EFG shown below were connected with line segments.
Then the sides of the triangle get half.
Then the perimeter will be of a new triangle will be
[tex]\rm Perimeter = \dfrac{8}{2} + \dfrac{15}{2} +\dfrac{12}{2}\\\\Perimeter = 17.5[/tex]
Thus, the midpoints of the sides of ∆EFG are connected with line segments, then the perimeter of that triangle is 15.5 cm.

Solve. A standard coffee mug has a capacity of 16 fluid ounces. If Annie needs to fill 6 mugs with coffee, how many total quarts of coffee does she need?
Answer: 3 quarts of coffee.
Step-by-step explanation:
A coffee mug can take 16 fluid ounces.
Annie needs to fill up 6 mugs so the total ounces needed for 6 mugs would be:
= 16 * 6
= 96 fluid ounces
As the answer needs to be in quarts, convert the above.
1 quart = 32 fluid ounces
96 fluid ounces = 96/32
= 3 quarts

5 The Raven Club sold tickets to the local fall festival. On day one, they sold 50 child tickets and 75 adult
tickets and the total was $525. On day two, they sold 45 child tickets and 65 adult tickets and the total
was $460. What was the cost of the adult tickets?
Answer:
Y = 6
Step-by-step explanation:
On the first day of ticket sales the school sold 3 adult ticket and 8 student tickets for a total of $72. The school took in $152 on the second day by selling 7 adult tickets and 16 student tickets. How much is a student ticket?
Day 1: 3x + 7y = 72
Day 2: 7x + 16y = 152
This becomes a system of equations.
3x+8y=72
3x+8y+−8y=72+−8y (Add -8y to both sides)
3x=−8y+72
3x/3 = −(8y+72)/3
X = (-8/3) y + 24
Substitute (-8/3) y + 24 for x in7x+16y=152:
7(-8/3 y + 24) + 16y = 152
-8/3 y + 168 = 152 (Simplify both sides of the equation)
-8/3 y + 168 − 168 = 152 + (−168) (Add -168 to both sides)
-8/3 y = -16
(-8/3 y)/(-8/3 y) = -16/ -8/3 y (Divide both sides by (-8)/3)
y = 6
