Answer:
B) y = 10x
Step-by-step explanation:
It should not be too hard for you to determine that every number on the bottom row is the same as the number on the top row with a zero appended.
Appending a zero to a number is the same as multiplying it by 10. For example, ...
... 90 = 10·9
... y = 10x
_____
In case that observation doesn't work out for you, you can always solve the given equation for k, then choose values from the table to fill in.
... y = kx
... k = y/x . . . . . divide by the coefficient of k, which is x
Fill in values from the table
... k = 20/2 = 10 . . . . . . from the second column
Now put this value where k is in the equation. After you do that, you know ...
... y = 10x
Answer:
11700 mm²
Step-by-step explanation:
Vertical height between the centres of top and bottom circles
sqrt[(2×28)² - 28²]
= 28sqrt(3)
Width of the rectangle
= 4×28
= 112
Length of the rectangle
= 28sqrt(3) + 2(28)
= 56 + 28sqrt(3)
Area = 112 × (56 + 28sqrt(3))
= 11703.71133 mm²
