Answer:
Length is 90yards and width is 60yards
Step-by-step explanation:
Perimeter= 2( length+width)
let the width be x
then the length will be 30 + x
300 = 2(30+x+x)
150 = 30 + 2x
120= 2x
x = 120/2
x = 60 yards
length= 30+x
= 30 + 60
= 90yards
Answer:
- 3 \frac{4}{5} + 1 \frac{2}{5}
= -frac{19}{5} +frac{7}{5}
= frac{-19+7}{5}
= frac{-12}{5}
= -2frac{2}{5}
5 \frac{3}{5} - 7
= -2+\frac{3}{5}
= frac{-10+3}{5}
= frac{-7}{5}
= -1\frac{2}{5}

Answer:
Hence, the relation R is a reflexive, symmetric and transitive relation.
Given :
A be the set of all lines in the plane and R is a relation on set A.
To find :
Which type of relation R on set A.
Explanation :
A relation R on a set A is called reflexive relation if every then .
So, the relation R is a reflexive relation because a line always parallels to itself.
A relation R on a set A is called Symmetric relation if then for all .
So, the relation R is a symmetric relation because if a line is parallel to the line the always the line is parallel to the line .
A relation R on a set A is called transitive relation if and then for all .
So, the relation R is a transitive relation because if a line s parallel to the line and the line is parallel to the line then the always line is parallel to the line .
Therefore the relation R is a reflexive, symmetric and transitive relation.
42 times 10 is 420 hope it helps you
Rounding is simple:
- If the previous digit is 5-9, round the number to the left of it up a number. If it is 4-0, leave the number to the left of it as it is.
For 82.98, we can round 82 to 83, since 82 is the whole number and the previous digit is 9 (so we round up).
For 169.645, we scratch off 45. Since 6 is in the tenth's place and the previous digit of it is 4, we leave it at 169.64.
