Answer:
Perimeter of shape B = 50 cm
Step-by-step explanation:
Perimeter of shape A = 60 cm
Let the length of each square = x cm
Total length of free boundaries of shape A = 12x
Therefore, 12x = 60
x = 5 cm
Now length surfaces of shape B = 10x
Perimeter of shape B = 10x
= 10(5)
= 50 cm
Answer:
4/7
Step-by-step explanation:
1/4 divided by 7/16 is the same thing as 1/4 * 16/7. Multiply this and you will get the fraction of 16/28. Once simplified, this comes out to be 4/7.

500
Step-by-step explanation:
multiple them together
Answer:
y = 0.5x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 1, y = 0.5, then
k = 
= 
= 0.5, hence
y = 0.5x ← equation of variation
