Two is equivalent to twenty and 84
Answer:
a). Distance from the surface of miner elevator=532 feet, Distance from the surface of equipment elevator=60 feet
b). The miner elevator is deeper since it is 472 feet deeper than the equipment elevator
Step-by-step explanation:
Equipment elevator speed=4 feet per second
Miner elevator=14 feet per second
Total time of miner elevator=(23+15)=38 seconds
Total time of equipment elevator=15 seconds
a). Distance from the surface of each elevator
Distance from the surface of miner elevator=Miner Speed×Miner Time
Distance=(14×38)=532 feet
Distance from the surface of equipment elevator=Equipment Speed×Equipment Time
Distance=(15×4)=60 feet
b). Which elevator is deeper
Distance from the surface of miner elevator=532 feet
Distance from the surface of equipment elevator= 60 feet
Difference=(532-60)=472 feet
The miner elevator is deeper since it is 472 feet deeper than the equipment elevator
I dont really understand this question, i really would of liked to help.
Answer:
the Bision is 10 miles / hour faster if he could keep it up
Step-by-step explanation:
There are 60 minutes in an hour.
Therefore the bison can run [3520 feet / min] * [60 min ] =211288 feet in an hour.
Now you have to convert 212200 to miles. Do this by dividing by 5280
212200/5280 = 40 miles.
Kind of hard to believe isn't it. 40 miles is a long way when you are running it.
The bison is faster by 10 miles / hour.
This can be done all in 1 step if you know how to do dimensional analysis
3520 feet / minute * [ 60 min/ hour ] * [ 1 mile / 5280 feet] = 40 miles
1. Let's call the short side 
and the long side 
.
2. The problem says that the short side is 1/3 the length of the long side. So, you can write the following expression:
3. The formula for calculate the area of a rectangle is:
4. Then, you must substitute and the value of the area into the formula and solve for (The long side):
5. Now, you can calculate (The short side):
Therefore, the answer is: 600 feet by 200 feet.
