Hannah invested $600 for 8 years at a rate of 3% per year simple interest. Calculate the interest Hannah receives.

Given:

Principal = $600

Rate of simple interest = 3% per year

Time = 8 years

To find:

The simple interest.

Solution:

Formula for simple interest is:

Where, P is principal, r is the rate of interest in percent and t is the number of years.

Substituting in the above formula, we get

Therefore, the simple interest is $144.

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
