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

Step-by-step explanation:

x^5 when x = -1 will be -1 because -1^5 = -1

-1 * -9 will equal 9

1/3^2 = 1/9

1/9*9 = 1

Answer:1

Step-by-step explanation:

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

Answer:

5089.4cm³ (rounded to 1 d.p.)

Step-by-step explanation:

Volume of cylinder = [tex]\pi[/tex] × r² × h

Volume of cylinder = [tex]\pi[/tex] × 9² × 20

                                = 1620[tex]\pi[/tex]

                                = 5089.4cm³ (rounded to 1 d.p.)

Answer:

D

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]

Step-by-step explanation:

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).

If you're trying to say find f(x) = 5ˣ when x = -3

The answer would be [tex]\frac{1}{125}[/tex]

A negative exponent means to put that value in the reciprocal. So the reciprocal of 5 is [tex]\frac{1}{5}[/tex]  . and the 3 means to multiply it 3 times like [tex](\frac{1}{5})(\frac{1}{5})(\frac{1}{5})[/tex] to get [tex]\frac{1}{125}[/tex]

Answer:

sure

Step-by-step explanation:

Answer: B and C

Step-by-step explanation: To start off, you subtract 3 from both sides, to get 4<z/2, then multiply both sides by 2, you get z>8. Now it's greater than 8, so it can't equal 8, so the answers would be B and C, since they are both greater than 8, and you have to select multiple choices.

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. In maximum structures of dimension a base unit for period is chosen, from which all different gadgets are derived. within the international system of devices device the bottom unit for duration is the metre.

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
