Answer:
15 square feet
Step-by-step explanation:
Multiply 1.5 by 3 which equals 4.5
Multiply 1.5 by 2 which equals 3
Add the above answers (4.5 plus 3)
Then multiply by 2 (7.5 times 2)
It equals 15
I hope this helps and that this is the right problem. There is no picture shown but I just did this problem for someone else so I thought I would take a shot at it :)
Answer:Except -1 for all real values of k given the equations has a unique solution.
Step-by-step explanation:
Except -1 for all real values of k given the equations has a unique solution.
Explanation:
Compare given linear pair of equations
(3k+1)x+3y-2 = 0 ----(1)
(k²+1)x+(k-2)y-5=0 ----(2)
with
----(2)
----(3)
we get ,
and
\* Given linear equations have unique solution *\
=> 3k(k-2)+1(k-2)≠3k²+3
=> 3k²-6k+k-2≠3k²+3
=> 3k²-5k-3k²≠3+2
=> -5k ≠ 5
Divide each term by (-5) , we get
=> k ≠-1
Therefore,
Except -1 for all real values of k given the equations has a unique solution.
Answer:
The correct answer that makes sense is A.
Step-by-step explanation:
It is A because if you add up the current values on the frequency column you get 91 and 91+109=200. Therefore, it shows that 200 people were surveyed And that if you take 109 and divide it by 2 then p and q will equal to 54.5.
Given:
The geometric sequence is
To find:
The explicit formula for the given geometric sequence.
Solution:
We have, a geometric sequence
Here,
First term :
Common ratio :
The explicit formula of a geometric sequence is
where, a is first term and r is common ratio.
Putting and r=3, we get
Therefore, the correct option is c.
