This density in kilograms per pint is 0.946.
Important conversions:
1 gram = 0.001 kilogram
1 ml = 0.001 litres
1 pint = 0.473 litres
1 litre = 2.113 pints
Step 1 : Convert 2 grams per millilitre of volume (2 g/ml) into kilograms per litre (kg/l)
Divide 2 grams per millilitre (g/ml) by 0.001 and multiply with 1000 to get the density in kilograms per litre (kg/l)=> (2 x 1000)/ (0.001) = 2 kg / l
Therefore, we get the density in kilograms per litre (kg/l) as 2 kg/l.
Step 2 : Convert the density in kilogram per litre (kg/l) into kilograms per pint (kg/pint)
Multiply 2 kilograms per litre with 0.473 to get the density in kilograms per pint=> 2 x 0.473 = 0.946 kg/l
Therefore, by converting 2 grams per millilitre of volume into kilograms per pint, we get the density as 0.946 kg/pint.

Gordon invests $2,500 for 20 months at a simple interest rate of 12.4%. the amount of interest received is found by i=prt since r= 0.124. i=0.124 x p x t. what are p and t?
The p and t represent Principal and time and interest is 517.7
We are given the formula to find the interest. So, the formula is -
I = (PRT) ÷ 100
In this formula, I refers to interest, P refers to Principal, R refers to rate of interest and T refers to time. Time will be in years and division by 100 is done for rate of interest.
Keep the values in formula to calculate the interest -
As per the known fact, 12 months = 1 year
So, 20 months = (1 ÷ 12) × 20
20 months = 1.67 years
Interest = (2500 × 12.4 × 1.67) ÷ 100
Performing multiplication in numerator
Interest = 51,770 ÷ 100
Performing division to find the interest
Interest = 517.7
Hence, p refers to principal and t refers to time. The interest that Gordon will receive will be 517.7.

Answer:
2x + 2 + h.
Step-by-step explanation:
F(x+h) is f(x) where x+h replaces x:-
f(x + h) = (x + h)^2 + 2(x + h) - 3
[f(x+h) - f(x)] / h
= (x + h)^2 + 2(x + h) - 3 - (x^2 + 2x - 3) / h
= [x^2 + 2hx + h^2 + 2x + 2h - 3 - x^2 - 2x + 3] / h
= (2hx + h^2 + 2h) / h
= 2x + 2 + h
The limit of [f(x+h) - f(x)] / h as h ----> 0 is 2x + 2.
We refer to 2x + 2 as the derivative of x^2 + 2x - 3.
In what situation would a geometric model be better than a binomial model
Binomial distribution describes the variety of successes k accomplished in n trials, wherein opportunity of achievement is p. Geometric distribution is a unique case of bad binomial distribution, wherein the test is stopped in the beginning failure (r = 1).
The not common definition of the Geometric distribution is the variety of trials till the primary achievement.. The following is an instance for the distinction among the Binomial and Geometric distributions: If a own circle of relatives comes to a decision to have five youngsters, then the variety of girls (successes) within side the own circle of relatives has a binomial distribution. If the own circle of relatives comes to a decision to have youngsters till they have got the primary lady after which stop, the the variety of youngsters within side the own circle of relatives has a Geometric distribution . A variant at the Geometric distribution is counting the variety of failures till the primary achievement, after which the variety may be 0,1,2,... In the instance it might be counting the variety of boys within side the own circle of relatives earlier than the primary lady turned into born, and now no longer the entire variety of youngsters. The distinction among the 2 versions is usually 1.

A guardrail's acceptable height range is 99cm to 113cm and the definite absolute value inequality is as follows | h - 106cm | ≤ 7cm,
How to define an inequality? A statement stating that one quantity is less than or (greater than) another.An inequality solution is a number that, when replaced for the variable, makes the inequality true.We understand that the height must be 106cm with a maximum absolute deviation of 7cm.
As a result, the maximum height is:
106cm plus 7cm = 113cm
The bare minimum is:
99cm = 106cm -7cm
This is represented by the absolute value equation:
| h - 106cm | ≤ 7cm

How many solutions does the equation have? 4h + 2 = 3h - 7
Answer:

Subtract 3h from both sides:
(4h + 2) - 3h = (3h - 7) - 3h
h + 2 = -7
Then, subtract 2 from both sides to isolate h:
(h + 2) - 2 = (-7) - 2

a = h/b, solve the formula for b
a = h/b
x b, both sides
ab = h
÷a
b = h/a
B = h/a
Hope this helps!
Answer: b = h/a
Step-by-step explanation: What you need to do is to get b by itself and to do that you have to move b to the other side because it's being divided by b. To do that you multiply by b on both sides.
1) ab = h
Now, isolate b by dividing a into both sides.
2) b = h/a
Now, you have b alone you know what b is equal to.
Solve the equation x+ 4x-7 = 0 by completing the square. give your answers correct to 2 decimal places.
[tex] {x}^{2} + 4x - 7 = 0 \\ → {x}^{2} + 4x = 7[/tex]
Add the square of the half of the coefficient of the unknown(x) to both sides of the equation.
[tex] {x}^{2} + 4x + ( \frac{4}{2} {)}^{2} = 7 + ( \frac{4}{2} {)}^{2}[/tex]
[tex] {x}^{2} + 4x + (2 {)}^{2} = 7 + (2 {)}^{2} [/tex]
[tex] {x}^{2} + 4x + (2 {)}^{2} = 7 + 4[/tex]
Bring out x and 2 and square them as shown below:
[tex](x + 2 {)}^{2} = 11[/tex]
Now, square root both sides of the equation to find the value of x as shown below:
[tex] \sqrt{(x + 2 {)}^{2} } = \sqrt{11} [/tex]
Add a + or - sign since it is a quadratic equation
[tex]x + 2 = \binom{ + }{ - } \sqrt{11} [/tex]
[tex]x + 2 = \binom{ + }{ - } 3.3166[/tex]
[tex]x = - 2 + 3.166 [/tex] or
