Answer:
No, a rhombus is a quadrilateral, with four equal-length sides and opposite sides parallel to each other. All rhombuses are parallelograms, but not all parallelograms are rhombuses. The opposite interior angles of rhombuses are always congruent. A parallelogram is just a four sided closed shape where opposite sides are parallel.

Answer:
15%
Step-by-step explanation:
100-85=15
100%= the total cost of the book
85%= price she bought it for
15%= the percentage the book was reduced by
For #3, it's 5.4 because you divide the total amount of money made by the amount of money earned per hour.
49.95/9.25=5.4 hours
Mowing 4 lawns in 6 hours gives a mowing rate of 6/4 = 1.5 hours per lawn.
To mow 9 lawns, you need 1.5*9 = 13.5 hours.
The answer is B.
Answer:
= - 3
Step-by-step explanation:
Note the common ratio r between consecutive terms, that is
r = - 18 ÷ - 3 = - 108 ÷ - 18 = 6
This indicates the sequence is geometric with n th term ( explicit formula )
= a
where a is the first term and r the common ratio
Here a = - 3 and r = 6, thus
= - 3
