Answer:
(3) Diagonals are perpendicular
Step-by-step explanation:
-133/2=-66.5
If we take the upper and lower round of that number we will get the 2 consecutive numbers that make -133.
Therefore the answer is -66 & -67.
36 divided by 90 gives the percent so its 0.4 which is 40%
650/300 = 2(1/6)
(1/6) of 1 hour = 10mins
The flight took 2hr and 10mins.
Given :
On average, a refrigerator door is opened 99 times each day.
Len has two refrigerators in his house.
To Find :
How many times in a 8−week period are the refrigerator doors opened.
Solution :
Number of times door opened for 2 refrigerator , n = 99×2 = 198.
Number of days in 8 week , d = 8×7 = 56 days.
So, total number of times doors open in a period of 8-week is :

Therefore, refrigerator doors are opened about 11088 times.
Hence, this is the required solution.
