Step-by-step explanation:

Material of 32 feet with the person is not sufficient to cover the square garden.
Tristan wants to build a square garden having area = 75 square feet
Since, Area of a square is given by the expression,
Area = (Side)²
By substituting the value of area in the expression,
75 = (Side)²
√75 = √(Side)²
5√3 = Side
Side = 8.66 feet
Since, perimeter of a square is given by the expression,
Perimeter of a square = 4(side)
Therefore, Perimeter of the square garden = 4(8.66)
= 34.64 feet
A person has a material of length = 32 feet
If the length of the material is enough to cover the square field,
Length of the material ≥ Perimeter of the garden
32 feet ≥ 34.64 feet
Which is false.
Therefore, material is not of enough length to cover the square garden.

Answer:
Y=4 X= -6 or (-6,4)
Step-by-step explanation:
Okay so
3x+10y=22
-3x-8y=-14
basically, it's like one big equation. First, subtract 3x from -3x which cancels out and gives us 010y minus 8y gives us 2y.22 minus 14 gives us 83x+10y=22
-3x-8y=-14
0+2y=8
Now that we have this, we can solve for y. in order to do this, we have to divide both sides by 2.
[tex] \frac{2y}{2} = \frac{8}{2} [/tex]
From here we know that y=4 because the 2s cancel out leaving y and 8 divided by 2 is 4.
y= 4
Now we can fill in. You can pick any equation for this but I'm going to chose the first one.
3x+10y=22
we can fill in 4 for y
3x+10(4)=22
3x+40=22
Next we are going to subtract 40 on both sides.
3x+40=22
-40 -40
3x= -18
Next, we're going to divide -18 by 3.
[tex] \frac{3x}{3} = \frac{ - 18}{3} [/tex]
The 3s cancel out leaving us x. -18 divided by 3 is -6.
x= -6

Answer:
x=40
Step-by-step explanation:
If the large angle is bisected, the two smaller angles are equal
x+30 = 3x-50
Subtract x from each side
x+30 -x = 3x-50-x
30 = 2x-50
Add 50 to each side
30+50 = 2x-50+50
80 =2x
Divide by 2
80/2 = 2x/2
40 =x
Answer:
x = 40
Step-by-step explanation:
since line KN bisects that angle, the two parts are equal to each other:
(x+30) = (3x-50)
x + 30 = 3x - 50
-2x = -80
x = 40
you can even check it to see if both angles are equal to each other by substituting 40 for x:
(40 + 30) = (3*40 - 50)
70 = 70
this checks out, so the answer is correct

"If the radius of the closed cone is doubled, show algebraically how this affects the surface area in comparison to the original cone."
How do I do this question?
Answers
Answer:
It would help to have the cone area formula:
Area = PI * radius * slant height
Let's say the height is 12cm radius is 5 cm
which makes the (slant height)^2 = 12^2 + 5^2 = 169
slant height = 13
and surface area = PI * 5 * 12 = 188.4955592154
If radius = 10 then (slant height)^2 = 12^2 + 10^2 = 244
slant height = 15.6204993518
surface area = PI * 10 * 15.62 = 376.99
376.99 / 188.4955 = 2
So, if radius is doubled, surface area is doubled.

The general form of the equation of a circle is x^2+y^2+8x+22y+37=0
The equation of this circle in standard form is (x+__)^2+(y+__)^2=__. The center of the circle is at the point (__,__).
Answers
Answer:
We know that the equation of the circle in standard form is equal to (x-h)² + (y-k)² = r² where (h,k) is the center of the circle and r is the radius of the circle.
We have x² + y² + 8x + 22y + 37 = 0, let's get to the standard form :
1 - We first group terms with the same variable :
(x²+8x) + (y²+22y) + 37 = 0
2 - We then move the constant to the opposite side of the equation (don't forget to change the sign !)
(x²+8x) + (y²+22y) = - 37
3 - Do you recall the quadratic identities ? (a+b)² = a² + 2ab + b². Now that's what we are trying to find. We call this process "completing the square".
x²+8x = (x²+8x + 4²) - 4² = (x+4)² - 4²
y²+22y = (y²+22y+11²)-11² = (y+11)²-11²
4 - We plug the new values inside our equation :
(x+4)² - 4² + (y+22)² - 11² = -37
(x+4)² + (y+22)² = -37+4²+11²
(x+4)²+(y+22)² = 100
5 - We re-write in standard form :
(x-(-4)²)² + (y - (-22))² = 10²
And now it is easy to identify h and k, h = -4 and k = - 22 and the radius r equal 10. You can now complete the sentence :)

Which is the formula
for the volume
of a cylinder?
A. V = a^2 + b^2 + c^2
B. V = (area of the base)(radius)
C. V = (area of the base)(height)
Answers
Answer: C. V = (area of the base)(height)
This applies to any prism. A cylinder is effectively a prism but the base is a circle rather than a polygon.
The cylindrical volume formula you may be more familiar with is
V = pi*r^2*h
note how the pi*r^2 portion is the area of the circular base. So we can replace the pi*r^2 with "area of the base" to end up with choice C.

The law of cosines can be used to find the distance from the outfielder to the pitcher. It tells you for triangle ABC, the length of side c can be found from ...
c² = a² +b² -2ab·cos(C)
Here, we hve a=60.5, b=214, and C=36°. Then the desired distance is ...
c = √(60.5² +214² -2·60.5·214·cos(36°)) ≈ √28507.56 ≈ 168.84
The outfielder throws the ball about 169 feet.
