Answer:
Step-by-step explanation:
Perimeter of a shape is the total distance around it.
The formula for determining the perimeter of a circle is
Perimeter = 2πr
Where
r represents radius of the circle.
π is a constant whose value is 3.14
The given circle has a radius of
225 ft. The perimeter would be
2 × 3.14 × 225 = 1413 ft
Therefore, the perimeter of the circular path of the base ball field would be
40/100 × 1413 = 0.4 × 1413 = 565.2 ft
The perimeter of the base ball field would be
565.2 + 300 + 300 = 1165.2 ft
Time = distance/speed
Time it will take you to run around the baseball field is
1165.2/9 = 129.5 seconds
Find the greatest common factor. That is 2.
Divide both numbers by 2.
14 ÷ 2 = 7
30 ÷ 2 = 15
Your answer is 7/15
Answer:
Instrumental understanding – having a mathematical rule and being able to apply and manipulate it. Relational understanding – having a mathematical rule, knowing how to use it AND knowing why it works.
Step-by-step explanation:
Instrumental understanding involves “memorising which problems a method works for and which not, and also learning a different method for each new class of problems” (Skemp 1987, p. 159), is a desire to know “some kind of rule for getting the answer” (p. 155) so that a student can “latch on it and ignore the rest”
