Since there are 14 boys and the whole class has 31 students
We get, the ratio of the part-to-whole relationship for boys is 14/31.
And since there are 17 girls
We get, the ratio of the part-to-whole relationship for girls is 17/31.
One possible solution is 10 hours of tutoring and 3 hours of landscaping.
<h3>
Inequality</h3>
Inequality is an expression used to show the non equal comparison of two or more numbers and variables.
Let x represents the number of hours tutoring and y represents the number of hours landscaping
From the question, we form the equations:
- x + y ≤ 13 (1)
- 18x + 9y > 180 (2)
A possible solution is (10, 3)
One possible solution is 10 hours of tutoring and 3 hours of landscaping.

-- A rhombus is always a parallelogram and a quadrilateral.
A rhombus can also be a square, but not all of them are.
-- A rectangle is always a parallelogram and a quadrilateral.
A rectangle can also be a square and a rhombus, but not all of them are.
-- A parallelogram is always a quadrilateral.
A parallelogram can also be a square, a rectangle, or a rhombus, but not all of them are.
-- A quadrilateral can be a square, a parallelogram, a rectangle, and a rhombus.
But not every quadrilateral needs to be any one of these things.
<em>However . . .</em>
-- You can definitely be sure that every square is always a quadrilateral,
a parallelogram, a rectangle, and a rhombus.
All four choices apply to a square, and should be selected.
