Find the percentage change from the first quantity to the second quantity: From $75 to $90

From 40 cm to 60 cm

From 20 gm to 5 gm

From 60 km/h to 45 km/h

From 5 dozen eggs to 100 eggs

1) 20% increase

2) 50% increase

3) 75% decrease

4) 25% decrease

5) 66.6667% decrease

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
