Multiply 5% by 30
0.05*30 = 1.50
$1.50 is 5% of $30
Answer: + =
Step-by-step explanation:
The equation of a circle is given as :
+ =
Where (a,b) are the coordinate of the center and r is the radius of the circle.
The end point of the diameter is give as (-5, -3 ) and ( -11 , -3 ) , This means that we can find the coordinate of the center by finding the mid point of the end point. The mid point is calculated by :
Mid point = ( , )
= -5
= -11
= -3
= -3
Substituting this values into the formula for finding mid point , we have
Mid point = ( ,
Mid-point = (-8 , -3)
Remember that Radius is half of the diameter , To find the diameter we must find the distance between the two end point using the formula for calculating distance between two points , that is
D =
Substituting the values :
D =
D =
D = 6
Therefore , The diameter i s 6
And since radius is half of the diameter , radius is thus
r = 6/2
r = 3
So , substituting the values gotten into the equation of circle , we have:
+ =
+ =
Answer:
13p
Step-by-step explanation:
Add 7 + 6.
=13
13 + p = 13p
13p is the simplified answer.
