Answer:
Radius refers to the distance between the center of the circle to any point of the circle
Diameter refers to the distance between any two points on the circle passing through the center of circle, it is also equal to radiusx2
Area of circle = πr², where π is a constant (≈3.14159), r is the radius
Halfcircles is basically half of the circle. It has the same radius and diameter as it's full circle but the area of the halfcircle is equal to half of the area of the full circle.

line y=3x-1 is transformed by a dilation with a scale factor of 2 and centered at (3,8) what is the lines image in an equation form
Answer: 4)y=3x-1
Step-by-step explanation:
The y value relates to the dilatation center, which the line image's equation will be [tex]y = 3x - 1[/tex]. In standard form, [tex]y = mx + b[/tex] y-intercept is represented by the letter b.
Center of dilatation calculation:[tex]y = 3x - 1[/tex] is the equation of a line.
If somehow the line is dilatable by a factor of 2 and centered at [tex](3, 8)[/tex]. To begin with, we must determine the y-value for which [tex]x = 3[/tex].
[tex]y = 3(3) - 1\\\\y = 9 - 1\\\\y = 8[/tex]
This equation of the line image will be [tex]y = 3x - 1[/tex], because the y value is comparable to the center of dilatation.

Sixty percent of the water from the full bottle holding 1.5 L was used to fill 5 similar cups leaving no remainder. How much water does 1 cup hold ?
Answer:
0.9 of a Liter for the bottle's volume
0.18 L for each cut
180 mL for each cup.
Step-by-step explanation:
60/100 * 1.5 = 0.6 * 1.5 = 0.90
There were 5 cups
The volume of the bottle was 0.9 liters
1 cup held 0.9 / 5 = 0.18 L
1 Liter = 1000 mL
0.18 L = 1000 *0.18 = 180 mL

Dracula's bill at the restaurant was $54.83. He left a tip of 15%.
What was the tip amount (nearest hundredth)?
PLEASE ANSWER QUICK :,(
15% as a decimal is 0.15
Multiply the amount of the bill by the percentage:
54.83 x 0.15 = 8.22
The tip was $8.22
Answer:
[tex]\huge\boxed{ \$ \ 8.22}[/tex]
Step-by-step explanation:
Bill = $54.83
Tip = 15 % of 54.83
[% means out of 100, "of" means to "multiply"]
Tip:
= 15% of 54.83
= 15 / 100 * 54.83

Answer:
x = 6, z=88
Step-by-step explanation:
The angle 92 and z lies on a straight line.
Therefore,
[tex]z + 92 = 180 \\ z = 180 - 92 = 88[/tex]
Same goes for Angle Z and 5x+62.
[tex]z + 5x + 62 = 180 \\ 88 + 5x + 62 = 180 \\ 150 + 5x = 180 \\ 5x = 180 - 150 = 30 \\ x = 30 \div 5 = 6[/tex]

The area of a rectangular pool is (x + 17x + 72) square meters. The dimensions of the pool are the factors of this polynomial. There is a 3-meter-wide concrete walkway around the pool. Write expressions to represent the dimensions of the outside border of the walkway. (Lesson 21.1)
Answer:
The walkway around the pool makes the entire outer dimensions (outer border)
x+9+2x3=x+15 and x+8+2x3
hope this helps! could i get brainliest plz?
The expressions to represent the dimensions of the outside border of the walkway is (x + 12) meters for the length and (x + 11) meters for the width.
Given area : [tex]x^2 + 17x + 72[/tex]
The factored form of the polynomial is:
[tex]x^2 + 17x + 72[/tex] = [tex]x^2 + 8x+9x+72[/tex]
= x(x+8)+9(x + 8)
=(x + 9)(x + 8)
So, the dimensions of the pool are (x + 9) meters and (x + 8) meters.
The length of the walkway = 3 meters wide
So, the length is added to each side of the pool.
Dimensions of the outside border of the walkway:
Length: (x + 9) + 3 = x + 12 meters
Width: (x + 8) + 3 = x + 11 meters
Therefore, the dimensions of the outside border of the walkway are
(x + 12) meters for the length and (x + 11) meters for the width.

Hiiiioo can someone please help me with this!❤️❤️:)
Answer:
7.4 in
Step-by-step explanation:
The diagonal divides the rectangle into 2 right triangles.
The diagonal is the hypotenuse and the length l is a leg ( adjacent) to angle
Using the cosine ratio in the right triangle
cos22° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{l}{8}[/tex] ( multiply both sides by 8 )
8 × cos22° = l , then l ≈ 7.4 in ( to the nearest tenth )
Find the value of x picture attached
Answer:
x = 10
Step-by-step explanation:
These angles are same side interior angles.
This means that (11x + 10) + (10x - 40) = 180
Solve for x:
11x + 10 + 10x - 40 = 180
21x - 30 = 180

Answer this using a graphing method!
Step-by-step explanation:
5x-2y=10
x-y=-1
Addition method
multiply the second equation by -2 and add it to the first one
5x-2y=10
-2x+2y=2
Total 3x=12
Divide by sides by 3
x=4
Now multiply the second equation by -5 and add it to the first one
5x-2y=10
-5x+5y=5
3y=15
Divide both sides by 3
y=5
Solutions are x=4 and y=5
2nd method
if x-y=-1, so x=y-1
bring the value of x in the first equation
5(y-1)-2y=10
5y-5-2y=10
put the similar term together
3y=15
Divide both sides by 3
y=5
now bring the value of y in one of the equation
x-y=-1
so x-(5)=-1
x=-1+5
x=4
Solutions are x=4; y=5

Answer:
Chad is incorrect
Step-by-step explanation:
Since A is in quadrant 2, we know the x must be negative and y is positive. Therefore, if we add a negative sign in front of both x and y, x will become positive, and y will become negative. However, in the 3rd quadrant, both x and y must be negative, which is not the case here. Hence, Chad is wrong.
