The volume of a gas "V" varies inversely with the pressure "P" put on it. If the volume is 360cm³ under a pressure of 20 kgcm2
Sav [38]

Answer:

15 Kg cm²

Step-by-step explanation:

Given that V varies inversely with P then the equation relating them is

V = \frac{k}{P} ← k is the constant of variation

To find k use the condition

V = 360, P = 20, then

360 = \frac{k}{20} ( multiply both sides by 20 )

k = 7200

V = \frac{7200}{P} ← equation of variation

When V = 480, then

480 = \frac{7200}{P} ( multiply both sides by P )

480P = 7200 ( divide both sides by 480 )

P = 15

All of number one thank you
Vadim26 [7]
I'm going to divide number one to 6 parts
1. \frac{4}{10} = \frac{40}{100}
2. \frac{7}{10} = \frac{70}{100}
3. \frac{2}{10} = \frac{20}{100}
4. \frac{9}{10} = \frac{90}{100}
5. \frac{18}{10} = \frac{180}{100}
6. \frac{26}{10} = \frac{260}{100}

because to make the denominator to 100, you need to multiply 10 by 10 which is 100.
and because you multiply 10, you also have to multiply the numerator by 10.
EXAMPLES: \frac{3}{10} = \frac{3}{10} × \frac{10}{10} = \frac{30}{100}

Can 4.7 be turned into a fraction
exis [7]

Answer:

Yes! It can

Fraction=4\frac{7}{10}

Decimals can convert into fractions!

4 is the whole number

.70 is

70 out hundredths

7/10 or 7/100

So the fraction would be

4\frac{7}{10}

Hope this helps!
