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

produces Pressure.</span>
Answer:
y = - 3x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (- 2, - 1) into the partial equation
- 1 = 6 + c ⇒ c = - 1 - 6 = - 7
y = - 3x - 7 ← equation of line
Answer: 12.5 in. high
Step-by-step explanation: to get from 4 to 10, you have to muliplty by 2.5.
if you multiply 5 by 2.5, the answer is 12.5
Answer:
No, they are not equal
Step-by-step explanation:
If x = 1
4(5+x) = 4(5+1) = 4 x 6 = 24
(5+4) + x = 9 +1 = 10
24
10

Answer:
$105
Step-by-step explanation:
The thicker wall takes 345 -205 = 140 more blocks. Each of those costs $0.75, so the added blocks will cost ...
140 × $0.75 = $105
The thicker wall will cost $105 more.
