The mass of a poppy seed is 0.0002985 g. Express this in scientific notation. What
will be the mass of 1 cup of poppy
seeds, if the cup can hold approximately
5,00,000 poppy seeds?​

Scientific notation is given by ax10^b therefore on solving .0002985g you will get 2.985x10^-4gm

Mass of 5,00,000 of such puppy is

500000x.0002985

FINAL: 149.25 gm.

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.
