Answer:
has 25, wants 130, so he needs to save (130-25)= 105.
105/7= 15 weeks
25+7w= 130
The length of the aqueduct is 13 km.
My reasoning for this is because the inner triangle is in perfect ratio to the outer triangle and the inner edge has a ratio of 1 to 5 so if you’re searching for the length of the aqueduct you would multiply the corresponding side which is 2.6 km x 5 to which you would get 13
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:
+ =
+ =
