Parallelogram ABCD has area 144, with AB = 16 and BC = 12. Find the length of segment DX.

12

Step-by-step explanation:

The area of a parallelogram is equal to its base times its height. Segment DX is a height relative to the base BC, so (area of ABCD) = BC times DX,

144 = 12 times DX.

So, DX is 12. :)

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
