The least common denominator for the function [tex]\frac{11x}{x^{2} +4x-12} -\frac{7}{2x^{2} -4x}[/tex] is (x -2).
What is least common denominator?The least common multiple of a group of fractions' denominators is known as the lowest common denominator, or Least Common Denominator.
Calculation for the least common denominator:
Consider the given expression,
[tex]\frac{11x}{x^{2} +4x-12} -\frac{7}{2x^{2} -4x}[/tex]
Further simplifying the equation by factorisation of the denominator part
= [tex]\frac{11x}{x^{2} +6x-2x-12} -\frac{7}{2x(x -2)}[/tex]
= [tex]\frac{11x}{(x+6)(x-2)} -\frac{7}{2x(x -2)}[/tex]
= [tex]\frac{1}{x-2}[/tex]×[tex][\frac{11x}{(x+6)} -\frac{7}{2x}][/tex]
Therefore, from the above result, it is found that (x-2) is the least common denominator that can be taken.

Answer:
d = 50h
Step-by-step explanation:
We are using the linear property y = mx.
We know that distance = rate × time, so if we subsitute this, we get that the distance is d, the rate is 50 mph, and the time is h.
Therefore, we can form the equation d = 50h.

tanx cscx= 1/f(x)
simplify and write the trigonometric expression in terms of sine and cosine
Answer:
f(x) = cos(x)
Step-by-step explanation:
tanx cscx = (sinx/cosx) * (1/sinx) = 1/cosx
1/f(x) = 1/cosx
f(x) = cos(x)
The given trigonometric equation in terms of sine and cosine is f(x)=cosx.
The given trigonometric function is tanx·cscx= 1/f(x).
What is the trigonometric equation?A trigonometric equation is one that involves one or more of the sixs sine, cosine, tangent, cotangent, secant, and cosecant. Some trigonometric equations, like x = cos x, can be solved only numerically, through successive approximations.
We know that, tanx = sinx/cosx and cscx=1/sinx
Now, 1/f(x) = tanx·cscx
= sinx/cosx × 1/sinx
= 1/cosx
So, 1/f(x) = 1/cosx
Take inverse on both the side of equation, we get
f(x)=cosx
Hence, the given trigonometric equation in terms of sine and cosine is f(x)=cosx.

Out of 4,000 colleges surveyed, 60% reported that SAT scores were not used as a high consideration in viewing their applications. How many schools view the SAT as important in screening applicants?
Answer:
Hi.
The first thing you want to know is how many schools 60% is.
To find 60%: 4,000 x 0.6 (b/c 0.6 = 60%)
so, 60% of 4,000 = 2,400
To find the number of schools that consider SAT scores:
Subtract 2,400 from 4,000 which, equals 1,600
or
Find the remaining percentage; 40%:
4,000 x 0.4 = 1,600
Answer: 1,600 colleges

Two cars leave the same parking lot, with one heading north and the other heading east. After several minutes, the northbound car has traveled 1 mile, and the eastbound car has traveled 4 miles. Measured in a straight line, how far apart are the two cars? If necessary, round to the nearest tenth.
Answer:
distance between two cars in a straight line = 4.12 miles
Step-by-step explanation:
The North and East make a right angle and if you make a straight line between the two cars you will make a right angled triangle.
Now we can use Pythagoras theorem to calculate the distance between two cars in a straight line.
p = 1
b = 4
h = ?
Using Pythagoras theorem
h² = p² + b²
h² = 1² + 4²
h² = 1 + 16
h² = 17
h = sqroot (17)
h = 4.12 miles
The distance between two cars is 4.12 miles.
Given that, two cars leave the same parking lot, with one heading north and the other heading east.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
The northbound car has traveled 1 mile = x=1 mile
The eastbound car has traveled 4 miles =y=4 mile
Let the distance between two cars be z
Using Pythagoras theorem, we get
z²=x²+y²
⇒ z²=1²+4²
⇒ z²=17
⇒ z=√17
⇒ z=4.12 miles
Therefore, the distance between two cars is 4.12 miles.

The break even point for this bookstore is n = 13.
What is Break-even Point?Break even point is the point where the total revenue and total cost are equal to each other. That is, person does not suffer from loss or does not acquire profit.
Given that,
Cost for the bookstore for a day to keep open = $78
Cost for each book = $14
Let n denote the number of books made or sold in a day.
Then total cost for n books = 78 + 14n
Selling price for each book = $20
Revenue from n books = 20n
Break even point is the point when,
Total revenue = total cost
20n = 78 + 14n
6n = 78
n = 13
Hence the break even point for the store is n = 13.

Gabrielle is 13 years older than Mikhail. the sum of their ages is 113. what is mikhails age?
Step-by-step explanation:
g=m+13
g+m=113
use substitution
Answer:
50 years old
Step-by-step explanation:
Let's say that Mikhail's age is x.
If so, Gabrielle's age would be 13 years older, therefore x + 13
We know that the sum of their ages is 113, so we can form this equation:
x + x + 13 = 113
Solving this equation, we get:
x + x = 100
2x = 100
x = 50
50 is Mikhail's age, so Gabrielle's age is 63

If the graph of the second equation in the system passes through (-12, 20) and (4,12), which statement is true?
THE amusement park won't allow kids to ride roller-coasters until they are a minimum of 48 inches tall. Michael is now 42 inches tall, and grows about 1/2 inch every month. How many months will it be until Michael can read a roller coaster? Please show me the individual steps?
Answer: It will one year (or 12 months) before Michael is able to ride the roller coaster.
Step-by-step explanation: Because he grows a half inch every month, this means that It takes him two months to grow one full inch. Because he has to grow six inches, you just multiply 2 by 6 to get 12 months or one year.
Answer:
48-42=6, which is how much Michael needs to grow.
1/2x=6, where x is the number of months
x = 12 months.
1 year = 12 months so the answer is one year.
