Answer:

  1.4.1  35.34 mm²

  1.4.2  113.10 mm

Step-by-step explanation:

1.4.1 There are 5 circles in the first two patterns. The area of one circle in terms of its diameter is ...

  A = (π/4)d²

Then the area of the 5 circles is ...

  A = 5(π/4)(3 mm)² = 45π/4 mm² ≈ 35.34 mm²

__

1.4.2 There are 12 circles in the first 3 patterns. The perimeter of one circle is given by the formula ...

  P = πd

Then the total perimeter of the 12 circles is ...

  P = 12π(3 mm) = 36π mm ≈ 113.10 mm

Answer: A) Point B, because if cups of frosting are 50, then drops of food coloring will be 200.


This is because the proportion of frosting to food coloring is 1:4, and if the answer to A is simplified (50:200), the ratio would be the same.

dlinn [17]
The expression of 25t +45m shows the total number of miles driven at both speeds. In order to solve this equation you would need to know the total number of hours driven in order to multiply that by the appropriate speed in terms of miles per hour.
