Answer:
Ok, I can see only a) to c)
a) Lucy spent the most time reading.
b) 20 minutes.
c) 22 minutes.
Step-by-step explanation:
Reason for b):
First convert hours to minutes.
1 hour = 60 minutes
4 hours = ?
4 × 60 = 240 minutes.
Homework is 30°
Total in the pie chart is 360° so:
30/360 × 240 mins = 20 mins
Answer is Zac spent 20 minutes to do his homework.
Reason for c):
Watching TV:
Zac: 135°
Lucy: 102°
Zac:
135/360 × 240 minutes = 90 minutes
Lucy:
102/360 × 240 minutes = 68 minutes
To find how many minutes Zac spent watching TV than Lucy:
90 minutes - 68 minutes = 22 minutes.
Do you understand, Kiara 12004?
Answer:
25 posts
Step-by-step explanation:
So the number of fence post would be the total length of the log divided by the length of each post. As the log is 16m and is corrected to the nearest metre, it could possibly be 16.499m. As for the post that is 70 cm long and corrected to the nearest 10cm, it may as well be 65 cm (or 0.65m) each post
So the max number of fence point once can possibly cut from the log would be
16.499 / 0.65 = 25 posts
Answer: Phelan now have 44.69 US dollars. of the original 250 US dollars.
Step-by-step explanation:
Given, Phelan spent 150 euros on his trip.
1 European euro = 1.3687 US dollars

≈ 205.31 US dollars [ Rounded to the nearest cent. ]
Initially he had 250 US dollars, now he has left (250-205.31)US dollars that is
44.69 US dollars.
Hence, Phelan now have 44.69 US dollars. of the original 250 US dollars.
