For squrae
area=side²
perimiter=4(side)
for circle
area=pir²
circumference=2pir
side=diameter, diameter/2=radius=side/2
find area not covered
that is areasquare-areacircle
areasquare=26²=676 sqauare inches
areaciecle, diameter=side, 26/2=13, area=pi13²=169*3.14=530.66 square inches
areanotcovered=676-530.66=145.34 square inches not coverd
ratio of perimiter to circumferece
perimiter=4*26=104
circumference=2pir=2pi13=26pi=26*3.14=81.64
circumference to perimiter is 81.64/104=0.785
Answer: The worker can not take his first break before 11:45 AM
Step-by-step explanation:
120 minutes = 2 hours
150 minutes = 2 hours 30 minutes
if the worker begins his job at 9:45 am and he is required to take a short break every 120 to 150 minutes from the time he resumes, then he can take his break 2 hours to 2 hours 30 minutes after 9:45 am.
So, 9:45 am + 2 hours = 11:45 am,
or 9:45 am + 2 hours 30 minutes = 12:15 minutes, the worker can only take a short break from 11:45 am to 12: 15 pm
Therefore, the worker can not take his first break before 11:45 AM
Answer:
i really dont understand is that the whole oimg??
Step-by-step explanation:
X= 1/2 or x = 3/2.
Step 1: factor left side of equation. (2x-1)(2x-3)=O
Step 2: Set factors equal to 0. 2x-1=0 or 2x-3=0
X= 1/2 or x = 3/2.
