Answer:
48 cm
Step-by-step explanation:
Here, we are concerned with finding the perimeter of the rectangle.
Now, since the square has an area of 9 cm^2, it means that the squares has a side of 3 cm each since the area of a square is s^2
So now, there are 5 squares in a row, meaning in a straight stretch , left to right or right to left, there are 15 squares. So the total length here is 5 * 3 = 15 cm
Now, moving column-wise, from top to bottom, since we have 3 rows, what this means is that per column of the rows, there are 3 squares. So the total length here becomes 3 * 3 = 9 cm
So we have a rectangle 9cm by 15cm
The perimeter is thus 2(L + B) = 2(15 + 9) = 2(24) = 48 cm
So,
To get how many wingbeats per minute,
200x60=12000 because there are 60 seconds in a minute
To get how many in 3 minutes,
12000x3=36000
Hope I helped!
Answer:
D
Step-by-step explanation:
It is the organized one with the center bar also being the largest value.
22. The information provided is the number of minutes worked for each weekday for two weeks.
23. Up to this point, no problem is stated. If we read ahead to question 24, the problem is to determine if the number of hours worked in a week exceeds 40. The steps to solve the problem are ...
... a) convert the times to compatible units (minutes to hours or hours to minutes)
... b) compare the total time worked in a week to 40 hours (or the equivalent), or compare the time worked each day to 8 hours.
... c) on the basis of the comparison(s) in (b), decide if overtime was worked.
24. 8 hours is (60 min/h)×(8 h) = 480 min.
Only 5 days were worked each week, and no day exceeded 8 hours (480 min), so the total time is less than 40 hours. Mary does NOT need to pay overtime.
