Answer:

Descending order:

14560g

13.6kg

13.25kg

12000g

a.) \(\frac{18}{5}\)

b.) \(\frac{25}{2}\)

Step-by-step explanation:

To find the difference between kg or g, either divide kg by 100 to convert to g, or multiply g by 1000 to convert to kg.

If we were to put everything into g:

14560g

13600g

13250g

12000g

See how they are still in the correct order?

If we were to put everything into kg:

14.56kg

13.6kg

13.25kg

12kg

Still in descending order!

___________________

Now to find out how to put the decimals into fractions:

Multiply by 10 (since there is only 1 digit behind the decimal, for every digit behind the decimal you multiply by another factor of 10, so if you have 2.55 you multiply by 100)

Following this we get:

36

125

Now divide by the same factor (10), we can't change the value of the number, just the way they look!

\(\frac{36}{100}\)

\(\frac{125}{10}\)

All that's left is it reduce!

\(\frac{18}{5}\)

\(\frac{25}{2}\)

And as you can see, we are back to the number I had put in the solution!

The value of ΔH°(2000 K) - ΔH°(0 K) for H(g) is the enthalpy change of formation of H(g) at 2000 K minus the enthalpy change of formation of H(g) at 0 K.

The enthalpy change of formation (ΔH°f) is the heat energy released or absorbed when one mole of a substance is formed from its elements in their standard states. To calculate ΔH°(2000 K) for H(g), we need to find the enthalpy change of formation of H(g) at 2000 K.

At 2000 K, H(g) is in a gaseous state. To determine its enthalpy change of formation, we compare it to the elements in their standard states. The standard state of hydrogen is H₂(g) at 298 K and 1 atm. Thus, we need to consider the energy required to convert H₂(g) at 298 K and 1 atm to H(g) at 2000 K.

The enthalpy change of formation at a specific temperature can be calculated using the equation:

ΔH°(T₂) = ΔH°(T₁) + ∫Cp(T)dT

Where ΔH°(T₂) is the enthalpy change of formation at temperature T₂, ΔH°(T₁) is the enthalpy change of formation at temperature T₁ (in this case, 298 K), Cp(T) is the heat capacity of the substance as a function of temperature, and the integral is taken over the temperature range from T₁ to T₂.

To obtain an accurate calculation, we would need the specific heat capacity data for H(g) over the temperature range from 298 K to 2000 K. Unfortunately, without this data, we cannot provide a precise value for ΔH°(2000 K) for H(g).

Step-by-step explanation:

The graph of the equation that is parallel to 4x – 3y = –12 is determined as: A. y = 4/3x - 3/2.

If two lines are parallel to each other, their graph will have the same slope value, m. This means if their equations are expressed as y = mx + b in slope-intercept form, they will both have the same value of m.

Given the equation of a graph as 4x - 3y = -12, rewrite it in slope-intercept form to determine the slope value:

4x - 3y = -12

-3y = -4x - 12

-3y/-3 = -4x/-3 - 12/-3

y = 4/3x + 4

This means the slope, m is 4/3. The slope of the graph that is parallel to it will also have a slope of 4/3.

The slope of y = 4/3x - 3/2 is also 4/3, therefore, the answer is: A. y = 4/3x - 3/2.

Step-by-step explanation:

55% of 20 = 11 (monkeys)

Answer: 50x - 27

Step-by-step explanation:

To find the 8th term of the arithmetic sequence, we need to first find the common difference between consecutive terms:

Common difference (d) = second term - first term

d = (8x - 3) - (x + 1)

d = 7x - 4

Now, we can use the formula to find the nth term of an arithmetic sequence:

an = a1 + (n - 1)d

where a1 is the first term, d is the common difference, and n is the term number we want to find.

Plugging in the values, we get:

a8 = (x + 1) + (8 - 1)(7x - 4)

a8 = x + 1 + 7(7x - 4)

a8 = x + 1 + 49x - 28

a8 = 50x - 27

Therefore, the 8th term of the arithmetic sequence x + 1, 8x - 3, 15x - 7 is 50x - 27.

Step-by-step explanation:

Defender 2 takes the shortest at approximately 16.33 seconds, and Defender 1 is in the middle at approximately 31.71 seconds.

Defender In this situation, we can calculate the time it takes for each of the defenders and the ball carrier to reach the end zone, assuming they all run in a straight line. Let's denote the speed of the ball carrier as x. Then, we can use the given ratios to find the speeds of the defenders:Defender 1 runs 1.1 times as fast as the ball carrier, so their speed is 1.1xDefender 2 runs 1.25 times as fast as the ball carrier, so their speed is 1.25x

Now, we can use the formula time

= distance ÷ speed to calculate the time it takes for each person to reach the end zone. For the ball carrier, the distance is 60 yards (since they start at the 40-yard line and want to reach the end zone at the 100-yard line), and the speed is x. Thus, their time is:time for ball carrier

= distance ÷ speed

= 60 yards ÷ xDefender 1 starts 10 yards away from the ball carrier, so their distance to the end zone is 50 yards. Their speed is 1.1x, so their time is:time for Defender 1

= distance ÷ speed

= 50 yards ÷ 1.1xDefender 2 starts 30 yards away from the ball carrier, so their distance to the end zone is 30 yards. Their speed is 1.25x, so their time is:time for Defender 2

= distance ÷ speed

= 30 yards ÷ 1.25x

Now, we can set up an equation based on the given information:time for ball carrier

= time for Defender 1 + time for Defender 260 yards ÷ x

= 50 yards ÷ 1.1x + 30 yards ÷ 1.25x

We can solve for x by multiplying both sides by the least common multiple of the denominators (8.75x):245 yards

= 400 yards ÷ 1.1 + 280 yards ÷ 1.25 Simplifying the right side gives:245 yards

= 363.64 yards + 224 yards Dividing both sides by 245 yards gives:1

= 1.48

Thus, the ball carrier runs at a speed of

x = 1.48.

Now we can calculate the times it takes for each person to reach the end zone:time for ball carrier

= distance ÷ speed

= 60 yards ÷ 1.48

= 40.54 seconds (rounded to two decimal places)time for Defender 1

= distance ÷ speed

= 50 yards ÷ 1.1(1.48) ≈ 31.71 secondstime for Defender 2

= distance ÷ speed

= 30 yards ÷ 1.25(1.48) ≈ 16.33 seconds

Thus, the ball carrier takes the longest to reach the end zone at approximately 40.54 seconds. Defender 2 takes the shortest at approximately 16.33 seconds, and Defender 1 is in the middle at approximately 31.71 seconds.

Number of students should be sampled to be within 0.5 drink of population mean with 95% probability is 617 students.

To determine the sample size required to estimate the population mean with a given level of precision, we can use the formula for the margin of error

Margin of error = Z × (standard deviation / sqrt(sample size))

where Z is the critical value of the standard normal distribution corresponding to the desired level of confidence. For a 95% confidence level, Z is 1.96.

We want the margin of error to be no more than 0.5 drinks, so we can set up the equation

0.5 = 1.96 × (6.3 / sqrt(sample size))

Solving for the sample size, we get

sqrt(sample size) = 1.96 × 6.3 / 0.5

sqrt(sample size) = 24.82

sample size = (24.82)^2

The algebraic expression x^2-4/x divided by x+2/x-2 when simplified gives (x-2)²/x

The difference of two squares method will be useful to solve this algebraic expression

The difference of two squares is a method of factorising used when an algebraic expression includes two squared terms, one subtracted from the other: a² - b² = (a+b)(a-b)

x^2-4/x divided by x+2/x-2 is x²-4/x  ÷  x+2/x-2

x²-4 = x²-2² = (x+2)(x-2). Thus:

x²-4/x  ÷  x+2/x-2 =  (x+2)(x-2)/x  ÷  x+2/x-2

                              =  (x+2)(x-2)/x  ×  x-2/x+2       The  (x+2) will cancel out

                                = (x-2)(x-2)/2
