<span>factors of 30 are numbers by which 30 is divisible.
if we list out 30 as a product of factors 30 = 1 x 30
30 = 2 x 15
30 = 3 x 10
30 = 5 x 6
therefore all the factors of 30 are - 1,2,3,5,6,10,15,30
the numbers 3 and 6 add up to 9.
therefore the 2 factors that add up to 9 are 3 and 6</span>
The answer is j+5-2
because sum means to add
<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
