K-mart is open from 8am to midnight on Monday to Saturday- there 16hrs from 8am to 12midnight
And on sunday it’s open from 10am to 8pm - so there is 10hrs from 10am till 8pm ....
So this is how you find your answer ...........✌️
*8am to 12midnight - 16hrs (Monday to Saturday)
*10am to 8pm - 10 hrs (Sunday)
*16hrs+10hrs=26
*26x7(days in a week )
*26x7=182
*therefore it’s opened for 182 hrs a week
....hrs means hours
Answer:
Area is 582 feet squared
Step-by-step explanation:
So, it suggests you break the shape apart, which is exactly what we can do to solve this problem.
We know that the longest side is 38ft, but to find the remaining length of the top, we will subtract 21 from 38.
So: 38ft - 21ft = 17ft
Now we can break the shape. The square will be 21 by 18 ft, and the remaining rectangle shape will be 12 by 17ft.
For the area, we'll start with the square. The formula for area is length times width: A=LW
For the square, we have the length, 21, and the width 18ft. All we have to do is multiply them:
21 * 18 = 378ft. squared
Now we can move on the rectangle, which has a length of 17ft, and width of 12ft.
12 * 17 = 204ft. squared
Last step! We add our areas together to get the entire shape's area. So..
378ft. + 204ft. = 582ft. squared
Good luck :P
Dr /dt = 7
A = pi r^2
dA / dr = 2pir
dA/dt = dA/dr * dr/dt = 2pir * 7 = 14pir
when r = 12 rate of change of the area = 14*pi*12 = 168pi
= 527.79 cm^2 / minute to nearest hundredth
Answer:
r=4
Step-by-step explanation:
-6=0.75(r-12)
-6= 0.75r-9
3=0.75r
r=4
