Answer:

180psi

Step-by-step explanation:

Step one:

given data

P1= 900 psi

T1= 350°C

P2=?

T2=70°C

Required

The final pressure P2

<em>Gay-Lussac's Law: The Pressure Temperature Law. This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. With an increase in temperature, the pressure will go up</em>

Applying the expression

P1/T1= P2/T2

substitute:

900/350= P2/70

2.57=P2/70

cross multiply

P2= 2.57*70

P2=180psi

Leonardo da vinci took out A simple interest loan at 12.75% interest for 12 months. His previous balance is % 942.36. What is hi
makkiz [27]

Answer:

A = 2,384.1708

Step-by-step explanation:

A = P(1  + rt)

P = 942.36

r = 12.75%

t = 12 months

A = 942.36(1 + 12.75/100(12))

A = 942.36(2.53)

A = 2,384.1708

Simplify this expression -6w + (-8) + 1+ (-7w)
Rzqust [24]

Answer:

\boxed{-6w+(-8)+1+(-7w)=-13w-7}

Step-by-step explanation:

The given expression is  -6w+(-8)+1+(-7w).


This expression is the same as;


 -6w+-8+1+-7w.

Or

 -6w-8+1-7w.


We regroup the terms to obtain;


-6w-7w-8+1


We simplify to get

-13w-7

You withdrew $36.25 from your checking account. Now your balance is -$14.75. Write and solve an equation to find the amount of m
iVinArrow [24]
Total was x
subtract 36.25 amount of money and you have -14.75 left

You can write this 
x - 36.25 = -14.75
add 36.25 to both sides
x = -14.75 + 36.25
Solve by combining like terms
x = 21.5

You had $21.5 on your account before you withdrew $36.25 and had a balance of -$14.75 left.

Hope this helps!
