Answer:
Step-by-step explanation:
Hour hand = radius = 5.5 in
It will travel one full circle in one day, and 3 full circles in 3 days.
<u>The travel distance is:</u>
- 3C = 3(2πr) = 6*3.14*5.5 in = 103.62 in
Answer: It will be explained below. Basically, 463.846154 minutes in total to read the rest of the book, and she reads at 78 pages per 90 minutes, or 13 pages per 15 minutes.
Step-by-step explanation: Shryia read 78 pages in 90 minutes - she had read 480-402, which is 78. This indicates a fairly annoying-to-calculate rate of 78 pages every 90 minutes, which is annoying to calculate, but please bear with it. The quantity of remaining pages is 402, of course, and as such we can simply divide this by 78 pages/90 minutes.
1. 402 pages divided by 78 pages/90 minutes
2. 402 pages multiplied by 90 minutes/78 pages (flipped the fraction; 90 minutes is now the numerator.)
3. 402 multiplied by 90 minutes/78 (reduced and removed the "pages" from each.)
4. 36180 minutes/78 (multiplied 402 to 90.)
5. 463.846154 minutes (divided 36180 by 78).
I hope this provides some insights.
Answer:
The highest floor that the ladder could safely reach is approximately 38.73 feet
Step-by-step explanation:
OSHA requirement for the use of non-self-supporting ladders includes the requirement that the horizontal distance between the point at the top where the ladder is supported and the foot of the ladder should be about a quarter of the ladder's working length
The given length of the longest ladder available at hardware stores, l = 40 feet
Therefore;
The horizontal distance between top support and the foot of the ladder, d = 1/4 × 40 feet = 10 feet
According to Pythagoras theorem, the height, 'h', of the ladder is goven as follows;
l² = d² + h²
∴ h² = l² - d²
Therefore, we have;
h² = 40² - 10² = 1500
h = √1500 = 10·√15
Therefore, the height of the highest floor that can be safely reached with the ladder, h = 10·√15 feet ≈ 38.73 feet.
