Answer:
72
Step-by-step explanation:
principal (P)=1800
time(T)=2yrs
rate(R)=2%
SI=?
now,
SI=PTR÷100
= 1800×2×2÷100
=7200÷100
=72
so interest is 72.
hope this will help you :D
Answer:
Area of the pool is 1250 square meters.
Step-by-step explanation:
Given:
1 cm on scale is 250 cm in actual.
Therefore, 20 cm on scale is 
10 cm on scale is 
Also, we know that, 
Therefore,

Area of the pool is given as,

Therefore, the area of the pool is 1250 square meters.
Step-by-step explanation:
so therefore mark jogged 2 36/70km more than his sister
The point (2, -3) lies in the IV quadrant since its x value is positive, but its y value is negative.

Given:
The center of the circle = (-1,0)
Point on the circle = (2,-4).
To find:
The equation of the circle.
Solution:
Distance between two points is

Distance between the center (-1,0) and the point on the circle (2,-4) is the radius of the circle.



On further simplification, we get



Now, the equation of the circle is

Where, (h,k) is the center and r is the radius of the circle.
The radius of the circle is 5 and the center is at (-1,0), so the equation of the circle is


Therefore, the first option is correct, i.e.,
.
