Hi there!
So -5 1/2 + 7 3/4 is
Improper fraction: 9/4
Decimal: 2.25
Mixed Number: 2 1/4
The remaining area that the grass will cover will be given by:
Area=[area of rectangle]-[area of the triangle]
area of rectangle will be:
A1=length*width
=20*8
=160 square feet
The area of the triangle will be:
A2=1/2absin theta
since the triangle is equilateral, all the angles are equal and the size of each angle is 60°. Thus the area will be:
A2=1/2*5*5sin 60
=18.3
thus the remaining area of the grass will be:
Area=160-18.3
=149.7 square feet
Answer:
Step-by-step explanation:
a) Capacity of the washing stage = 10*60/30 = 20 orders/hour
b) Capacity of the drying stage = 15*60/40 = 22.50
c) Washer is bottleneck because capacity of washing stage is lower
d) Capacity of Money laundry = (10+15)*60/(30+40) = 25*60/70 = 21.43 orders/hour
e) Bacause washer is bottleneck, they should buy washer
f) Utilization of washers on average = 8/20=40%
g) Utilization of dryers on average = 8/22.5 = 35.56%
h) On average there are 5 orders in washing stage
5/8 =0.625
j) On average there are 7 orders in drying stage
7/8 = 0.875
j)Order stay in Money laundry for 0.625 + 0.875 = 1.5 hour
