Answer:

8 weeks

Step-by-step explanation:

Let x represent how many weeks they will be in France.

The tour in Britain can be represented by 2x, since it is twice as long as the one in France.

The tour in Germany can be represented by x - 2, since it is 2 weeks shorter.

Create an equation and solve for x:

(x) + (2x) + (x - 2) = 30

4x - 2 = 30

4x = 32

x = 8

So, they will be in France for 8 weeks

On a soccer team 40% of the goal are scored by a star player on the team.If 70 goals were scored all season, how many are scored
VMariaS [17]

Answer:

42

Step-by-step explanation:

During the season, 40% of the goals are scored the by the star player.  This means that 60% of the goals are scored by everyone else.

100% - 40% = 60%

To find how many goals are scored by the rest of the team, convert the percentage to a decimal.  You then have to multiply the decimal by the total goals scored.

60% = 0.6

70 × 0.6 = 42

The rest of the team scored 42 goals.

5) What is the pressure of a 3 moles of oxygen in a 5 liter container at 300
blondinia [14]

Answer:

1496.52 Pa, 14.76 atm

Step-by-step explanation:

This question can be solved using ideal gas law

according to which

pv = nrt

where p is the pressure of gas

v is volume of gas

n is amount gas in moles

R is ideal gas constant whose value is 8.314 J/mol

T is absolute temperature of gas on Kelvin scale

______________________________

given

v = 5 liter

n = 3

T = 300 kelvin

R = 8.314 J/mol

Let the pressure be p

Substituting the above value in ideal gas law equation we have

p*5 = 3*8.314*300

p = 7482.6/5 = 1496.52 Pa

This pressure is in pascal while option is in atm

we know 1 Pascal is equal to 0.0000098692 atm

we know that 1 Atm = 101325 Pa

thus, 1496.52 is equal to  0.0000098692*1496.52 atm

1496.52 is equal to 14.76 atm
