Answer:
The length of the patio is 32 ft and the width is 13 ft
Step-by-step explanation:
see the attached figure to better understand the problem
Let
L ----> the length of his patio
W ---> the width of his patio
we know that
----> equation A
----> equation B
substitute equation B in equation A and solve for W
Find the value of L
----> 
therefore
The length of the patio is 32 ft and the width is 13 ft
Given that in arithmetic sequence a=5 and common difference, d=4. Thus the number of terms of this sequence that must be added to attain 4185 will be found as follows:
the explicit formula for arithmetic sequence is given by:
sn=n/2(2a+(n-1)d)
where n is the number of terms:
thus plugging in the values we get:
4185=n/2(2*5+(n-1)4)
solving for n we get:
8370=(10+4n-4)
8370=(6+4n)
4n=8364
n=8364/4
n=2091
thus the number of terms will be:
2091
Answer:
I guess the answer would be
Step-by-step explanation:
Answer: The value of whole is 120.
Step-by-step explanation:
Since we have given that
84 is 70% of the whole.
Let the whole be 'x'.
According to question, it becomes,
So, we have use the proportion i.e. 
to determine the value of whole.
Hence, the value of whole is 120.
