Answer:

x= -2/9

Step-by-step explanation:

2(x-2)/5=4x

2(x-2)=4x*5

2(x-2)=20x

x-2=20x/2

x-2=10x

-2=10x-x

9x= -2

x= -2/9

Probability of not picking up a red marble = 8/15

No of red marbles = 7

No of green marbles = 5

No of blue marbles = 3

Total sample space = 3+7+5 = 15 marbles

Probability of picking out blue marble = 3/15

Probability of picking out red marbles = 7/15

Probability of picking out green marbles = 5/15

Probability of not picking up a red marble  = 1 - 7/15 = 8/15

Answer: 2.52Hg

Step-by-step explanation:

First and foremost, we should realize that:

1 moles Mercury = 200.59 gram

Therefore, the number of moles of mercury, Hg is in a sample of 505 grams would be calculated as:

= 505/200.59

= 2.52

Answer:

 its 83

Step-by-step explanation:

The fraction is [tex]\frac{3}{5}[/tex]

Let's take the fraction as [tex]\frac{a}{b}[/tex]

According to the first statement,

If we add 1 to the numerator and subtract 1 from the denominator a fraction reduces to 1.

[tex]\frac{a + 1}{b - 1}[/tex] = 1

a + 1 = b -1

a + 2 = b

b = a + 2........(1)

According to the second statement

If we only add 1 to the denominators, it becomes 1/2.

[tex]\frac{a}{b+1}[/tex] = 1/2

2a = b + 1

b = 2z -1 .........(2)

Equating both the equation (1) and (2)

2a - 1 = a + 2

2a - a = 2 + 1

a = 3

Now substitute the value of a in equation (1)

b = 3 + 2

  = 5

Therefore the fraction is [tex]\frac{a}{b}[/tex] = [tex]\frac{3}{5}[/tex]

The length of longer piece is 2L/3 and shorter piece is L/3;

Let the length of string be 'L';

Let the longer piece be 'L₁' and shorter piece be 'L₂';

L₁ + L₂ = L;   -(i)

According to question;

L₁ = 2L₂;       -(ii)

Using (ii) in (i);

3L₂ = L;

L₂ = L/3;

L₁ = 2L/3;

length is a measure of distance. within the international machine of quantities, length is a amount with dimension distance.

Answer:

straight line that passes through the origin

Step-by-step explanation:

Two variables are said to have a direct variation or proportional relationship if it can be represented by y = kx, where k is a constant.

Comparing this with the equation of a straight line y = mx + b, where m is the slope of the line and b is the y intercept (value of y when x = 0), We can tell if the say that the graph of a direct variation or proportional relationship is a straight line with no y intercept (b = 0, that is it passes through the origin).

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

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

Applying the expression

P1/T1= P2/T2

substitute:

900/350= P2/70

2.57=P2/70

cross multiply

P2= 2.57*70

P2=180psi
