Explain the differences in the process of adding two rational expressions using the lowest common denominator (LCD) and adding them using a common denominator that is not the LCD. Include an example in your explanation.
When adding two rational expressions using the lowest common denominator (LCD), you need to find the smallest common multiple of the denominators and use it as the common denominator. Then, multiply the numerators of each fraction by the appropriate factor, add the numerators together and simplify if possible.
Explanation:When adding two rational expressions using the lowest common denominator (LCD), you need to find the smallest common multiple of the denominators and use it as the common denominator. Then, multiply the numerators of each fraction by the appropriate factor to make the denominators the same. Finally, add the numerators together and simplify if possible.
For example, if you want to add 1/2 and 3/4, the LCD is 4. Multiply the numerator and denominator of the first fraction by 2 to get 2/4. Then, add the numerators together: 2/4 + 3/4 = 5/4. However, this fraction can be simplified to 1 1/4.

3. There are about 1.61 kilometers in 1 miles. Let x represent a distance measured in kilometers and y represent the same distance measured in miles. Write two equations that relate a distance measured in kilometers and the same distances measured in miles.
We have been given that there are about 1.61 kilometers in 1 miles.
Let x represent a distance measured in kilometers and y represent the same distance measured in miles.
We can set two equations from the given information as:
[tex]x=\frac{1}{1.16}*y[/tex] (Number of kilometers in terms of number of miles)
[tex]y=1.61*x[/tex] (Number of miles in terms of number of kilometers)
Therefore, [tex]x=\frac{1}{1.16} y[/tex] and [tex]y=1.61*x[/tex] will be our equations.
To relate a distance measured in kilometers and miles, two equations can be written: y = 1.61x and x = 0.62y.
Explanation:To write equations that relate a distance measured in kilometers and the same distance measured in miles, we can use the conversion factor between kilometers and miles. Based on the given information, 1 mile is equivalent to 1.61 kilometers. So, the first equation would be: y = 1.61x, where x represents the distance in kilometers and y represents the distance in miles. To find the equation in the opposite direction, we can use the inverse of the conversion factor, which is 1 divided by 1.61. So, the second equation would be: x = 0.62y.

A swimming pool and deck are built in a rectangle with length 40ft and width 18ft.If the pool itself is 320 square feet,what is the area of the deck itself?
Calculate total area by multiplying the length by the width:
40 ft x 18 ft = 720 square feet total.
Now subtract the area of the pool:
720 - 320 = 400 square feet for the deck.

Solve for s.
0.5s+1=7+4.5s0.5s+1=7+4.5s
Answer:
[tex]s=-1.5[/tex]
Step-by-step explanation:
Given the equation :
[tex]0.5s+1=7+4.5s[/tex]
the first step is to put all the terms with the variable we want to solve for on one side of the equation, in this case I will put all the terms with [tex]s[/tex] on the right side, and all the independent terms on the left side.
[tex]1-7=4.5s-0.5s[/tex]
Solving for [tex]s[/tex] we have the following:
[tex]-6=4s[/tex]
[tex]\frac{-6}{4} =s[/tex]
[tex]-1.5 =s[/tex]
the answer is: [tex]s=-1.5[/tex]

8+4a+6.2-9a simplify expression
8 + 6.2 + 4a - 9a
(8 + 6.2) + (4 - 9)a
14.2 - 5a is your answer.
Answer:
Well,[tex]8+4a+6.2-9a[/tex] has like terms. The simplified expression would just be these like terms combined.
First, let's combine [tex]8[/tex] and [tex]6.2[/tex]
[tex]8+6.2=14.2[/tex]
[tex]4a-9a+14.2[/tex]
Now, combine the other two monomials.
[tex]4a-9a=-5a[/tex]
[tex]-5a+14.2[/tex] would be your answer.
Remember: Some terms can't be combined. For example, [tex]4a[/tex] and [tex]8[/tex] cannot be added together, due to the [tex]a[/tex] in [tex]4a[/tex]. These are not like terms. But [tex]4a[/tex] and[tex]-9a[/tex] are, and can indeed be combined.

3t - 18 = 4(-3 - 3/4t)
3t - 18 = 4(-3 - 3/4t)
Use distributed to remove parenthesis right side
3t-18= -12-3t
Add 3t by 3t
3t+3t-18=-12
6t-18=-12
Add 18 to both sides
6t=-12+18
6t= 6
Divide 6 both sides
6t/6=6/6

what’s 9•1085•(17•x)
Hi!
So I believe your question is 9(1085)(17*x)
So we can start to simplify 17 and x into 17x
Next we take 17x*1085= 18,445x
And finally we multiply 18,445x*9
18,445x*9=166,005x

Final answer:
To find the depth of the ocean using the travel time of a signal and the speed of sound in seawater (1450 m/s), multiply the travel time (here, 2.5 seconds) by the speed of sound and then divide by two, as the signal travels the distance twice. In this case, the depth would be 1812.5 meters.
Explanation:
To calculate how deep the ocean is at a given point where a ship sends out a signal and receives it back after a certain time, you need to use the speed of sound in water and the time it takes for the signal to travel to the ocean bottom and back. Since the signal travels the distance twice, the depth can be found by dividing the total distance traveled by two.
Let's consider the example where the signal returns after 2.5 seconds. With the speed of sound in sea water being 1450 m/s, the total distance covered by the sound wave is the product of the speed of sound and the time taken which is 1450 m/s * 2.5 s. However, since this distance is the round trip, to find the depth of the ocean at that point, we need to divide the result by 2.
The calculation will look like this:
Speed of sound in seawater = 1450 m/sTime for signal to return = 2.5 secondsTotal distance traveled by the sound wave = 1450 m/s * 2.5 s = 3625 metersDepth of the ocean = Total distance traveled / 2 = 3625 meters / 2 = 1812.5 metersDaniel is paid $10 per week for selling newspaper subscriptions.

The doubling time of a city’s population is 22 years. How long does it take for the population to quadruple?
A) 4 Years
B) 44 Years
C) 22^4
D) 2^22
Explain the answer.
The time it takes for a city's population to quadruple, given a doubling time of 22 years, is 44 years since quadrupling requires two doublings of the population.
The question asks about the time it will take for a city’s population to quadruple given that its doubling time is 22 years. To find the time it takes for the population to quadruple, we need to understand that quadrupling the population means doubling it twice. Since the doubling time is 22 years, we simply need to multiply this time by 2 to get the time for the population to quadruple.
Therefore, the correct answer is 44 years (B). This is because:
First doubling: 22 years
Second doubling (to quadruple): 22 + 22 = 44 years
