75/100 = 0.75

--------------------

12 x 0.75 = 9

* The mine elevator travels a
distance of 9 metres per minute.

---------------------

After 2 minutes, the mine elevator
would've travelled 18 metres,
therefore your answer is:

A: -18 metres

The volume of 400 mL of chlorine gas at 400 mm Hg is decreased to 200 mL at constant temperature. What is the new gas pressure?
rusak2 [61]

A. Let us first assume that the gas acts like an ideal gas so that we can use the ideal gas equation:

PV = nRT

where P is pressure, V is volume, n is number of moles, R is universal gas constant and T is absolute temperature

In this case, let us assume that nRT = constant so that:

P1V1 = P2V2

400 mm Hg * 400 mL = P2 * 200 mL

P2 = 800 mm Hg

 

<span>B. The collision of gas with the walls of the container produces Pressure.</span>

Last year the depth of the river was 4.2 feet deep. This year it dropped 25%. Find the depth of the river this year to cross it.
Novosadov [1.4K]

Answer:

The river is 3.15 feet deep.

Step-by-step explanation:

First let's recognize what we need to find: the depth of the river

We know last year the river was 4.2 feet deep, but it dropped 25%. This means we also need to find how much it dropped. To find this, we need to know what 25% of 4.2 is. Write an equation for this.

y = 25% of 4.2

y = 0.25 • 4.2

y = 1.05

This means that the river dropped 1.05 feet. To know its depth now, we need to subtract 1.05 from 4.2. Write an equation for this.

d = 4.2 - 1.05

d = 3.15

The river is 3.15 feet deep.

Hope this helps!

John has $220 in his account and adds $25 to it each month Cheryl has $100 in her account and adds $35 each to her account. How
sammy [17]

Answer: In 12 months they will have the same amount, which will be $520.

Step-by-step explanation:

220 + 25m = 100 + 35m

m = month

Subtract 100 from each side

120 + 25m = 35m

Subtract 25m from each side

120 = 10m

Divide each side by 10

12 = m
