Answer:
5
Step-by-step explanation:
Remember, the rank of a matrix is the number of pivots or number of rows different of zero in the echelon form of the matrix.
Then, if A is a matrix 
the maximum number of pivots that can have is one by row, that is, 5.
Then the maximum rank that A can have is 5.
Find r :
C=2πr
280=2(3.14)r
r=280/2(3.14)
r=44.6cm
find area :
A=πr²
A=3.14(44.6)²
A=6246 cm²
Answer : 4)6,246
Then, distance of route passes the beach = x
Let the distance of route that passes the park = x+2
So, their sum would be: x+x+2 = 2x+2
So, option C Is your answer.......
Answer:
<h2>4</h2><h2>11</h2>
Step-by-step explanation:
20:5=4 (minutes for 1 meter)
4*11=44 minutes for 11 meters
or
20 : 5 = x : 11
x = 20*11:5
x = 44
or
20:5* 11=44
Answer:
1 17/40
Step-by-step explanation:
5/8+4/5
We need to get a common denominator of 40
5/6 * 5/5 = 25/40
4/5*8/8 =32/40
25/40 + 32/40 = 57/40
57/40 = 40/40 + 17/40 = 1 17/40
