Answer:
They need 2 and 1/2 rolls.
Step-by-step explanation:
Area = length x width
A = l x w
A = 20 x 3
A = 60 ft²
If 60 ft² = 1 roll
What about 150 ft² = ?
= (150 x 1) ÷ 60
= 150 ÷ 60
= 2.5
= 2 and 1/2 rolls
Dc is a side of the parallelogram
Subtract 3n and then divide by 4 and you get n= 4
Answer:
88
Step By Step
Step-by-step explanation:
An arithmetic sequence is defined as
an=a+d(n-1) where an=nth term, a=initial term, n=term number, and d=common difference
For sequence 1,4,7... a=1 and d=4-1=7-4=3 so
an=1+3(n-1)
an=3n-2, so the 30th term is
an=3(30)-2
an=88
