<u>Answer</u>

320 cm³


<u>Explanation</u>

Firstly, find the constant of proportionality.

V ∝ 1/p

V = k/p   Where V= volume, k = constant and p = pressure of the gas.

1600 = k/4

k = 1600 × 4

   = 6,400

The equation will be,

V = 6,400/p

For p =20 Kg/cm²,

V = 6,400/20

   = 320 cm³

When are the expressions 3x +12 and 3(x+4) equvialent
zysi [14]

Answer:

For any value of x

Step-by-step explanation:

Solve by using system of equations!

3x+12

3(x+4)=3x+12

3x+12=3x+12

x=x

This means that any value of x would create the same answer for both equations.

Do the easiest percentages first:For me its this order to figure it out,
20% of 60 is 12 -double 10%-
5% of 60 is 3 -half of 10%-
15% of 60 is 9 - 10% + 5%-
60% of 60 is 36 -10% x 6-
Add all these together so 12+3+9+36 =60 so he doesn't need to print anymore double check this though!!

Pachacha [2.7K]

Answer:

11.2 feets

Step-by-step explanation:

Angle, P = 180 - (38 + 90) = 52

Using trigonometry :

Length pq:

SinP = opposite / hypotenus

Sin52 = 8.8 / pq

0.7880107 * pq = 8.8

pq = 8.8 / 0.7880107

pq = 11.167361

Hence, length of pq = 11.2 feets
