A gold mine has two elevators one for equipment and another for miners. The elevator for the miners descends 13 feet per second.

saveliy_v [14]

Answer:

The equipment elevator is positioned 481 feet closer and the miner equipment is positioned 342 feet closer relative to the surface. The equipment elevator is deeper.

Step-by-step explanation:

The rate that both elevators descend are the same according to the information given in the question.

After 18 seconds, the equipment elevator has descended 18 x 13 = 234 feet.

After another 19 seconds, the equipment elevator has descended for a total of 37 seconds which results in 481 feet and the miner elevator has descended for 19 seconds which gives us a descend of 342 feet.

So they are 481 and 342 feet closer relative to the surface and the equipment elevator is deeper since it has descended for a longer period of time.

I hope this answer helps.

What is 1 10th of 800grams

Alexandra [31]

So, I understand that you one 1/10th, that is one tenth or $\frac{1}{10}$

so:

$\frac{1}{10}$ *800= $\frac{800}{10}$ =80

The answer is 80.

I calculated this by dividing both the nominator and the denominator by the same number - this is always allowed. This number is 10.
