Answer:
I saw this exact question somewhere else! Here's the answer.
Step-by-step explanation:
Answer:
The area of the remaining board is [(L × B) - (l × b)].
Step-by-step explanation:
Suppose the bigger rectangle is labelled as ABCD and the smaller rectangle is labelled as PQRS.
Consider that the length and breadth of the bigger rectangle are L and B respectively. And the length and breadth of the bigger rectangle are l and b respectively.
The area of any rectangle is:
Area = Length × Breadth
The area of the bigger rectangle is:
Area of ABCD = L × B
The area of the smaller rectangle is:
Area of PQRS = l × b
Then the area of the remaining board will be:
Area of remaining board = Area of ABCD - Area of PQRS
= (L × B) - (l × b)
Thus, the area of the remaining board is [(L × B) - (l × b)].
add the mileage 51+69 = 120 km
add the times 4+5=9 hours
now divide the two
120/9 = 13.3 km per hour average speed
Any value which is more than 2 standard deviations away from the mean is considered to be "unusual."
2 standard deviations above the mean 52.4 mp would be 52.4+2(1.8), or 56; 2 std devs below the mean would be 52.4 - 2(1.8), or 48.8. Thus, any value larger than 56 or any value smaller than 48.8 would be "unusual."
54.8, 49.1 and 51.3 are not unusual; 56.5 is unusual, because it's greaster than 56.
Answer:
The dimensions of the field are 65 feet and 715 feet
Step-by-step explanation:
Let the length be L and the width be W.
Given W = 11L
Perimeter of the rectangle = 2(L + W) = 1560 feet
2(L + 11L) = 1560
L = 65 feet
W = 715 feet
