Step-by-step explanation:
Alex bought a new skate board at 20% discount. He paid $72. What percent of the original price did he pay?
Step 1
We find the original price
= Percent Discount × Original price =
= 20% × Original price = $72
= 0.2 × x = $72
x = $72/0.2
x = 360
They are opposites. since |-3| has the lines around it, this represents absolute value, which is not positive or negative but how far away the value is from 0. the plain -3 remains the same. |-3| is 3, because it is 3 units away from 0 on the number line.
Answer:
7 hours
Step-by-step explanation:
25.75(total cost of the rental)
-10.00 (cost of initially renting the bike)
----------------
15.75$ (cost of hourly fees)
15.75/2.25(hourly rate) = 7
Answer:
(x-2)2+(y-5)2=92
or
(x-2)2+(y-5)2=81
Step-by-step explanation: Center:(2,5)
The center of a circle is a point from which all points on a circle are the same distance.
Radius:9
The radius of a circle is the length of a line segment from its center to its perimeter.
The radius is typically denoted as "r" or "R".
Diameter:18
The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.
Circumference or (or Permieter) = 2*π*R = 2*3.14*9 = 56.5486677646163
The circumference of a circle is the distance around it.
Area:254.469004940773
Area of a Circle is the amount of space occupied by the circle.The area of a circle is p times the radius squared, which is written: A = π*R2.
The standard form for the equation oif a circle is
(x-a)2+(y-b)2=r2
And in our particular case:
(x-2)2+(y-5)2=92
(x-2)2+(y-5)2=81
The general form for the equation of a circle is
x2 + y2 + Ax + By + c = 0
We can get the general form by expanding the equation of the standard form
(x-a)2+(y-b)2=r2
(x-2)2+(y-5)2=92
(x-2)2+(y-5)2=81
x2-4x+4+y2-10y+25=81
x2+y2-4x-10y-52=0
