Answer:
A 31/45
Step-by-step explanation:
A 31/45=0.6888 (this is the awnser as the line on top means repeating)
B 682/999=0.682 (0.68 rounded)
C 62/99=0.62626 (repeating)
D 2/3=0.66666 (Or 0.67 rounded)
Answer:
The upper bound for the perimeter of the rectangle = 427.76 cm
Step-by-step explanation:
To obtain the upper bound for the perimeter, we need to first obtain the upper bound for the Length and Breadth of the rectangle.
Since, these dimensions were rounded to the nearest 1 decimal place, we can write down their ranges
Length = 127.3 cm
Width = 86.5 cm
Length can range from 127.25 cm to 127.34 cm
Breadth can range from 86.45 cm to 86.54 cm
The upper bound for the Length and Breadth of the rectangle are this 127.34 cm and 86.54 cm respectively.
Perimeter = 2 (L + B)
Upper bound of the perimeter
= 2 × (127.34 + 86.54)
= 2 × 213.88
= 427.76 cm
Hope this Helps!!!
B.The two figures are similar
Answer:
Rectangle C is 14 cm longer than B
Step-by-step explanation:
Let x be the length of Rectangle A. Rectangle B is ¹/₅ longer than A Block B,
Therefore the length of rectangle B is:
Rectangle C is ¹/₃ longer than B, therefore the length of rectangle c is:
The total length of all three rectangles is 133 cm.
Length of rectangle A + Length of rectangle B + Length of rectangle C = 133 cm
Therefore the length of rectangle A is 35 cm, the length of rectangle B is 
and the length of rectangle C is 
Rectangle C is ¹/₃ longer than B, which is 14 cm (42\3) longer than B
