What is the simplified form of the rational expression below? 6x^2-54/5x^2+15x
The simplified form of the rational expression 6x^2-54/5x^2+15x is 6(x - 3)/5x. This was achieved by factoring the original expressions, cancelling out common terms, and applying the difference of squares formula.
Explanation:The subject here is the simplification of a rational expression. First, let's factor the numerator (6x^2 - 54) and the denominator (5x^2 + 15x). The common factor in the numerator is 6 and in the denominator is 5x. After factoring we get:
6x^2 - 54 = 6(x^2 - 9)
5x^2 + 15x = 5x(x + 3)
Now, we can use the property a^2 - b^2 = (a + b)(a - b) to further simplify x^2 - 9 to (x - 3)(x + 3). This gives our new numerator as 6(x - 3)(x + 3).
The denominator 5x(x + 3) remains the same. Therefore, the simplified form of the rational expression is 6(x - 3)(x + 3)/5x(x + 3). The (x + 3) terms can be cancelled out leaving us with the final simplified rational expression of:

one gallon is equal to about 3.785 liters .what is the greatest number of whole liters of water u could pour into a one-gallon container without it overflowing ? explain your answer
We know that there are about 3.785 liters in 1 gallon. From here we could pour 3 whole liters into a one-gallon container without overflowing since 3 < 3.285 liters. But if we try to pour the next whole liter( 4 liters) it would be too much since 4 is greater then 3.785 liters. So the answer is 3 liters.

The manager of a store orders model railroad sets that cost $390 and sells them for $429. What is the mark-up, as a percentage?
Answer:
10%
Step-by-step explanation:
We have been given that the manager of a store orders model railroad sets that cost $390 and sells them for $429.
We will use markup % formula for our given problem.
[tex]\text{Markup percentage}=\frac{\text{Selling price- Cost}}{\text{Cost}}\times 100[/tex]
[tex]\text{Markup percentage}=\frac{429-390}{390}\times 100[/tex]
[tex]\text{Markup percentage}=\frac{39}{390}\times 100[/tex]

Miss Johnson drives to work everyday when she left for work one day the automator mileage gauge on her car read 38643.8 when she returned to her house at the end of the day the automator red 38 points 668.6 if she didn't drive anywhere else during the day but to work and back how many miles is it from her house to her work explain how you got your answer
Answer:
Distance from her house to her work = 12.4 Miles
Step-by-step explanation:
Given :-
==> Automator mileage gauge read 38643.8 Miles before she left to work.
==> Automator mileage gauge read 38668.6 Miles after she came home from work.
==> She didn't drive anywhere else during the day. home to work & work to home.
Car driven during the day = 38668.6 - 38643.8
= 24.8 Miles
Let the distance from home to work be X
*It is assumed that Distance from home to work = Distance from work to home
So, Distance from work to home = X
Total distance driven during the day = Distance from home to work + Distance from work to home
Total distance driven during the day = X + X
24.8 = 2X
24.8 ÷ 2 = X
12.4 = X
Distance from her house to her work = 12.4 Miles
Answer: I think the answer is 24.8

Step-by-step explanation:
well you just dividde the number in half and add the half and continue this and that's the seventh term. please be grateful it took me five minutes to do this
The seventh term of this sequence is 34.17875
Given : Each consecutive term is calculated by adding the half of preceding term to the preceding term.
Like : 2 + 1/2 (2) = 2 + 1 = 3
3 + 1/2 (3) = 3 + 3 / 2 = 3 + 1.5 = 4.5 or 4 1/2
4.5 + 1/2 ( 4.5 ) = 6.75
Similarly :
6.75 + 1/2 (6.75) = 10.125
10.125 + 1/2 (10.125) = 15.1875
15.1875 + 1/2 (15.1875) = 22.78125

6691 ÷28. solved by long divison
To calculate 6691 divided by 28 using long division, divide each set of numbers step by step to arrive at a quotient of 238 with a remainder of 27, resulting in a decimal of approximately 238.96 when rounded.
The question involves the process of long division which is a method used in arithmetic. The student is trying to divide 6691 by 28:
Divide 66 by 28, which goes 2 times. Write 2 above the division bar, to the right of the first quotient place.
Multiply 2 by 28, which is 56, and subtract that from 66 to get a remainder of 10. Bring down the next digit, 9, to make 109.
Divide 109 by 28, which goes 3 times. Write 3 on the division bar. Multiply 3 by 28 (equals 84) and subtract from 109 to get 25.
Bring down the next digit, 1, to make 251. Divide this by 28, which goes 8 times. Eight times 28 is 224. Subtract this from 251 to get 27.
27 is less than 28, so the division process stops here. The answer up to this point is 238, with a remainder of 27.
The long division calculation of 6691 divided by 28 is 238 with a remainder of 27 or as a decimal, 238.96.

A 30m tall building casts a shadow. the distance from top of the building to the top of the shadow is 36m. Find the lengths of the shadow
Final answer:
Using the Pythagorean theorem, the length of the shadow cast by a 30m tall building, with a diagonal distance of 36m from the top of the building to the top of the shadow, is calculated to be approximately 19.9 meters.
Explanation:
To find the length of the shadow cast by a 30m tall building, we can use the Pythagorean theorem. This theorem relates the lengths of the sides of a right triangle. Here, the building and its shadow form the two legs of a right triangle, and the line from the top of the building to the top of the shadow is the hypotenuse.
Let's denote:
The height of the building (opposite side) as O = 30m
The length of the shadow (adjacent side) as A
The distance from the top of the building to the top of the shadow (hypotenuse) as H = 36m
According to the Pythagorean theorem, we have:
O2 + A2 = H2
Plugging in the known values, we get:
302 + A2 = 362
900 + A2 = 1296
A2 = 1296 - 900
A2 = 396
A = √396
A ≈ 19.9m (rounded to one decimal place)
Therefore, the length of the shadow is approximately 19.9 meters.

Answer:
Perimeter of ΔAKL is, [tex]27 +9 \sqrt{3}[/tex] units.
Area of ΔAKL is, [tex]\frac{81\sqrt{3} }{2}[/tex] square units
Step-by-step explanation:
Given: In ΔAKL , AK = 9 units , [tex]m\angle K = 90^{\circ}[/tex] and [tex]m\angle A= 60^{\circ}[/tex].
In ΔAKL
[tex]\tan (A) = \frac{KL}{AK}[/tex]
Substitute the value AK = 9 units and [tex]m\angle A =60^{\circ}[/tex] to solve for KL ;
[tex]\tan(60^{\circ}) = \frac{KL}{9}[/tex]
[tex]\sqrt{3} = \frac{KL}{9}[/tex]
⇒[tex]KL = 9\sqrt{3} units[/tex]
In right angle ΔAKL,
Using Pythagoras theorem;
[tex]AL^2 = AK^2+KL^2[/tex] ......[1]
Substitute AK = 9 units and [tex]KL =9\sqrt{3} units[/tex] in [1] to solve for AL;
[tex]AL^2 = 9^2+(9\sqrt{3})^2[/tex]
[tex]AL^2 = 81+(81 \cdot 3)[/tex]
[tex]AL^2 = 81+243 = 324[/tex]
[tex]AL = \sqrt{324} = 18 units[/tex]
Perimeter of triangle is the sum of all the sides.
Perimeter of triangle AKL = AK +KL +AL = [tex]9 + 9\sqrt{3} + 18 = 27 +9 \sqrt{3}[/tex] units.
Formula for Area of right angle triangle is given by:
[tex]A = \frac{1}{2} Base \times Height[/tex]
Area of triangle AKL= [tex]\frac{1}{2} (9\sqrt{3}) \times (9)[/tex]
= [tex]\frac{81\sqrt{3} }{2}[/tex] square units
Final answer:
The perimeter of triangle AKL is approximately 29.09 m, and the area is 20.25 m², calculated using the properties of a 30°-60°-90° right triangle.
Explanation:
To find the perimeter of △AKL, we need to determine the lengths of all three sides. We know that AK = 9 m, ∠K = 90° (which makes △AKL a right triangle), and ∠A = 60°. Because the angles in a triangle add up to 180°, ∠L must be 30° (180° - 90° - 60°). In a 30°-60°-90° right triangle, the lengths of the sides are in the ratio 1:√3:2. Thus, if AK is the side opposite the 60° angle, AL must be half of AK, and KL must be AK times √3.
Therefore, AL = ½ × 9 m = 4.5 m, and KL = √3 × 9 m ≈ 15.59 m. The perimeter is the sum of AK, AL, and KL: 9 m + 4.5 m + 15.59 m ≈ 29.09 m.
The area of △AKL can be found using the formula for the area of a right triangle, which is ½ × base × height. AK and AL can serve as the base and height, respectively, so the area A is ½ × 9 m × 4.5 m = 20.25 m².

Alice planted some corn in the back yard and measures it’s height regularly. The last time she checked, the stalks were 60 inches tall. Now they are 72 inches tall. What is the percent of increase in the height of the stalks?
The percentage increase in the height of the corn stalks is 20%. This was calculated by subtracting the old height from the new height, dividing by the old height, and then multiplying by 100.
Explanation:The question is asking about the percentage increase in the height of the corn stalks that Alice planted. The stalks were previously 60 inches tall and now, they are 72 inches tall.
The formula to calculate the percentage increase is:
[(New Value - Old Value) / Old Value] x 100%
Substituting the given values into the formula, we get
[ (72 - 60) / 60 ] x 100%
This simplifies to [12/60] x 100%, which equals to 20%.
Therefore, there has been a 20% increase in the height of the corn stalks.

Noelle went shopping and bought each of his nine nephews a gift, either a video costing $14.95 or a CD costing $16.88. She spent $140.34 on the gifts. How many videos and how many CD’s did he buy?
Noelle bought gifts for her nine nephews and the total cost of these gifts is given. By setting up equations and solving them, we find that she purchased 6 videos and 3 CDs.
Step by Step Solution:
Noelle bought gifts for her nine nephews, which can be either videos costing $14.95 each or CDs costing $16.88 each, and spent a total of $140.34. We need to determine the number of videos and CDs she bought.
Let's denote the number of videos Noelle bought by V and the number of CDs by C. We can set up the following equations based on the given information:
V + C = 9 (as she bought gifts for nine nephews)
14.95V + 16.88C = 140.34 (total amount spent)
To solve these equations, we can use the substitution or elimination method. Let's use substitution:
From equation (1), we get:
C = 9 - V
Substitute this into equation (2):
14.95V + 16.88(9 - V) = 140.34
Expanding and simplifying:
14.95V + 151.92 - 16.88V = 140.34
-1.93V + 151.92 = 140.34
-1.93V = 140.34 - 151.92
-1.93V = -11.58
V = 6
Substitute V = 6 back into C = 9 - V:
C = 3
Therefore, Noelle bought 6 videos and 3 CDs.
