Hey there! I'm happy to help!

A <u>quadrilateral </u>is any polygon (enclosed shape) with four sides. Let's see what each of these shapes are.

  1. Scalene right triangle - the prefix <u>tri-</u><u> </u>means <u>three  </u>(tricycle, tripod, triple, etc.<u>),</u> and all triangles have three sides, so this is not a quadrilateral.
  2. Obtuse scalene triangle - once again a triangle, so not a quadrilateral.
  3. Isosceles right triangle - would you look at that, another triangle! Not a quadrilateral.
  4. Hexagon - a hexagon is a six-sided polygon (<u>hex=six)</u>, so this is not a quadrilateral.
  5. Pentagon - a pentagon is a five-sided polygon (<u>pent=five, </u>like Pentatonix!). Not a quadrilateral
  6. Right trapezoid - a trapezoid is a quadrilateral with at least one pair of parallel sides!
  7. Venn diagram - a Venn diagram is a compare and contrast chart made of two overlapping circles (ZERO sides), so this is not a quadrilateral.

So, the only shape on your list that is a quadrilateral is 6. right trapezoid.

Have a wonderful day! :D

Nina deposits $3500 into savings account. The rate of simple interest is 5.5% p.a.
REY [17]
A) $3500*0.055 = $192.50 . . . . the interest paid each year

B) The problem makes no mention of compounding, so we assume simple interest is paid. (Most accounts do not work this way.)
.. at the end of 1 year, 3500 +192.50 = $3692.50
.. at the end of year 2, 3692.50 +192.50 = $3885.00
.. at the end of year 3, 3885.00 +192.50 = $4077.50
.. at the end of year 4, 4077.50 +192.50 = $4270.00
.. at the end of year 5, 4270.00 +192.50 = $4462.50
