Answer:
Common difference = 5.
Step-by-step explanation:
General term of an arithmetic sequence is a1 + (n - 1)d where a1 = first term and d = common difference.
So here the first term is 8 + (1-1)d = 8 and the 10th term = 8 + (10-1)d = 53
giving 8 + 9d = 53
9d = 45
d = 5.
A parallelogram is a quadrilateral with 2 pairs of opposite, equal and parallel sides. A rectangle is a quadrilateral with 2 pairs of opposite, equal and parallel sides BUT ALSO forms right angles between adjacent sides.
Step-by-step explanation:
a)
8÷2=4
12÷3=4
27÷9=3
•it does'nt always take the same amount of time to serve each customer .
•10×3=30
b)
according to the question
2=18 point
4=36 point
8=72 point
18=9×2
36=9×4
72=9×8
so 1dollar =9point
•each dollar spent appears to earn the same number of point
•because 81=9×9, it costs 9 dollar
Because of each patches have an area of 2 square feet, so 2q = 12
Set x to 0 to find the y value or set y to 0 to find the x value
