Step-by-step explanation:
Last month Jordan received a promotion and became a manager he now earns the same amount as Serena how much more money does he earn per hour now that he is manager than he did before his promotions explain your thinking.
To find out how much more money Jordan earns per hour now, you would subtract his old wage from his new wage. For example, if his old wage was $8/hr and his new wage is $12/hr, he is making $4 more per hour now.
Explanation:The question does not provide the exact amount that Jordan was earning before the promotion or the current rate that both Jordan and Serena are earning now. However, you can find out how much more Jordan is earning now by subtracting his old hourly wage from his current wage (which is now equal to Serena's). For example, if Jordan was making $8 an hour before his promotion and is now making $12 an hour as a manager (the same as Serena), then he is earning $4 more per hour since his promotion.
Here's a step-by-step explanation:
Determine Jordan's wage before the promotion (Let's say it was $8 per hour)Find out Jordan and Serena's current wage (Let's say it's $12 per hour, since they are earning the same amount)Subtract Jordan's old wage from his new wage ($12 - $8 = $4) to find out how much more he earns per hour now.This is a mathematical problem dealing with subtraction to figure out the increase in wages.

How do you compare integers
Comparing integers involves assessing their relative positions on the number line. A positive integer is always greater than a negative one. Among negative integers, the one closer to zero is greater.
Explanation:To compare integers, you should first understand that integers are whole numbers that can be either positive or negative. If two integers are positive, the integer with the higher value is greater. If two integers are negative, the integer with the lower value is greater. If one is positive and the other is negative, the positive integer is always greater.
For example, when you compare the integers 3 and -5, you can say that 3 is greater than -5 because it is a positive number while -5 is negative. When comparing -2 and -7, -2 is greater because its value is closer to zero. It's also important to consider the concept of absolute value; the absolute value of an integer is its distance from zero on the number line, regardless of direction.
In situations that involve ratio problems or interval scale data, the comparison of integers becomes significantly important. For instance, if the scores on an exam are 80, 68, 20, and 92, you can rank the scores from lowest to highest (20, 68, 80, 92), and infer that a score of 92 is 24 points higher than a score of 68.

Using Hooke's law, F spring=k delta x, find the distance a spring with an elastic constant of 4 N/cm will stretch if a 2 newton force is applied to it.
A.) 2 cm
B.) 1/2 cm
C.) 4 cm
D.) 8 cm
Hello!
Using Hooke's law, F spring=k delta x, find the distance a spring with an elastic constant of 4 N/cm will stretch if a 2 newton force is applied to it.
Data:
Hooke represented mathematically his theory with the equation:
F = K * Δx
On what:
F (elastic force) = 2 N
K (elastic constant) = 4 N/cm
Δx (deformation or elongation of the elastic medium or distance from a spring) = ?
Solving:
[tex]F = K * \Delta{x}[/tex]
[tex]2\:N = 4\:N/cm*\Delta{x}[/tex]
[tex]4\:N/cm*\Delta{x} = 2\:N[/tex]
[tex]\Delta{x} = \dfrac{2\:\diagup\!\!\!\!\!N}{4\:\diagup\!\!\!\!\!N/cm}[/tex]
simplify by 2
[tex]\Delta{x} = \dfrac{2}{4}\frac{\div2}{\div2}[/tex]
[tex]\boxed{\boxed{\Delta{x} = \dfrac{1}{2}\:cm}}\Longleftarrow(distance)\end{array}}\qquad\checkmark[/tex]
Answer:

if a sea otter swam 5.6 miles per hour for 1.5 hours, how many miles did the sea otter swim?
Multiplying the sea otter's swimming speed of 5.6 miles per hour by the time spent swimming of 1.5 hours, we find that the sea otter swam a total of 8.4 miles.
If a sea otter swam 5.6 miles per hour for 1.5 hours, we can calculate the total distance covered by multiplying the speed of the sea otter by the total time swum. This is because distance is the product of speed and time according to the formula:
Distance = Speed ×Time
So, for the sea otter:
Distance = 5.6 miles/hour × 1.5 hours = 8.4 miles
Therefore, the sea otter swam a total of 8.4 miles.

One half u subtracted from 3 times u
The expression 'one half u subtracted from 3 times u' translates into the algebraic expression 3u - (½u), which simplifies to 2½u or 2.5u.
Explanation:The expression 'one half u subtracted from 3 times u' can be translated into an algebraic expression. To do this, we need to understand basic operations with variables. One half of u is ½u or 0.5u, and three times u is 3u. Therefore, the expression would be written as 3u - (½u).
Subtracting one half of u from 3 times u involves the operation of subtraction, and when you subtract ½u from 3u, the resulting expression simplifies to 2½u or 2.5u. This shows how a grasp of fractions and variables allows us to manipulate and simplify algebraic expressions.

Selina is planning to paint a large picture on a wall. She draws a smaller version first. The drawing is 8 inches by 6 inches. If the scale of the drawing is 2 in : 1 ft, what is the area of the actual picture on the wall?
If it's possible, can you list step-by-step the procedures? Thanks!
Final answer:
To find the actual picture's area, multiply the drawing's dimensions by the scale factor of 6, convert it to feet, and calculate the product to get 12 square feet.
Explanation:
The student asks for the area of an actual picture on a wall based on its scale drawing. The scale of the drawing is stated as 2 inches to 1 foot, which means each 2 inches on the drawing corresponds to 12 inches (1 foot) in reality. The steps to calculate the area are as follows:
Calculate the scale factor: Since 2 inches on the drawing corresponds to 12 inches, in reality, the scale factor is 12 inches \/ 2 inches = 6.Determine the actual dimensions: Multiply the dimensions of the drawing by the scale factor. The actual width is 8 inches * 6 = 48 inches, and the actual height is 6 inches * 6 = 36 inches.Convert dimensions to feet: Since 1 foot is 12 inches, the actual dimensions in feet are 48 inches \/ 12 inches per foot = 4 feet (width) and 36 inches \/ 12 inches per foot = 3 feet (height).Calculate the actual area: Multiply the actual dimensions. Area = width * height = 4 feet * 3 feet = 12 square feet.Therefore, the area of the actual picture on the wall is 12 square feet.
