what is the LCD of 1/a²-1 and 1/a+1
Answer:
[tex]a^{2} -1[/tex]
Step-by-step explanation:
The LCD, or the lowest common denominator would be [tex]a^2-1[/tex]
If we multiply the second term [tex]\frac{1}{a+1}[/tex] by [tex]\frac{a-1}{a-1}[/tex] ([tex]\frac{a-1}{a-1}[/tex] is equivalent to 1, so we can do this,) we can see that the denominator would become the same as the first term [tex]\frac{1}{a^2-1}[/tex] by difference of squares. So that creates an LCD of [tex]a^2-1[/tex]

A bike path starts on one side of the parking lot, goes around a small pond, and comes out on the other end of the parking lot. Following the path, a biker rides 100.0 meters directly east, then turns south and rides 200.0 meters. From there, she turns and rides 150.0 meters at an angle of 30.0° south of west. Turning one last time, she rides 250.0 meters at an angle of 60.0° north of west. What is her final displacement (distance and direction) from her starting point?
A cyclist rides 5.0km due east, then 10.0km20° west of north. From this point she rides 8.0km .

question is in image, and answer choices are here:
5, 4, 8, 10
Answer: x is equal to 4
Step-by-step explanation:
A triangle's angles sums up to 180°. So we already know that the three angles in this triangle add up to 180°. The equation would be as following.
(18x - 12) + 15x + (10x + 20) = 180
We first add like terms together.
43x + 8 = 180
We then substract 8 on both sides.
43x = 172
We finally divide 43 on both sides.
x = 4

Find the measures of two supplementary angles if their measures are given in the given ratio
11:25
Solution :
Let the measure of the supplementary angles be 11x and 25x
According to the question :
[tex] \tt \: 11x + 25x = 180 {}^{ \circ} \\ \\ \\ \tt \dashrightarrow \: 36x = 180 {}^{ \circ} \\ \\ \\ \tt \dashrightarrow x = \frac{180{}^{ \circ} }{36} \\ \\ \\ \: \: \: \: \: \: \: \dashrightarrow \: { \underline{ \boxed{ \mathfrak{ \pmb{ \purple{x = 5}}}}}} \: \: \pink{\bigstar} \\ \\ [/tex]

Answer:
13571 total
13600 to nearest hundred
Step-by-step explanation:
7+3 = 10 = distribution total
9500 / 7 = 1357.14286 one part
1357.14286 x 3 = 4071.42858 = 4071 males
1357.14286 x 10 = 13571.42 is the same as
9500 + 4071 = 13571 total
= 13600 to nearest hundred

The sum of negative eight and a number divided by four is two
Answer:
x = 16 or [tex]\frac{-8 + x}{4} = 2[/tex]
Step-by-step explanation:
let's start from the beginning and move along!
the sum (+) of negative eight (-8) and a number (x) ----> (-8 + x)divided by four (/4) is two = 2[tex]\frac{-8 + x}{4}[/tex] = 2
to solve this...
1) multiply both sides by four to get rid of the fraction
[tex](4)\frac{-8 + x}{4} = 2(4)[/tex] ------> -8 + x = 8
2) add 8 to both sides to isolate x ----> x = 16
A cricket pitch measures 1 chain by 10 feet. What is the area of a cricket pitch in square feet?
Answer:
660 square feet
Step-by-step explanation:
1 chain = 66 feet
Length ( l ) = 66 feet
Breadth ( b ) = 10 feet
To find :
The area of a cricket pitch in square feet = ?
The area of a cricket pitch in square feet will be in the shape of rectangle.
Formula : -
Area of a rectangle = lb
Area of a rectangle
= 66 x 10
= 660 square feet
Therefore,
660 square feet is the area of a cricket pitch.
Answer:
660
Step-by-step explanation:
I chain = 22 * 3 so to find the area we have to do (22*3) * 10 = 660

Which of the following is NOT an equivalent expression to Area of sector =
Answer:
Step-by-step explanation:
From the following, which is NOT an equivalent expression to Area of sector is 2πrθ/360. Option A is correct.
What is the area of a circular sector?The area of the circular sector is the space occupied by it. The area of the circular sector is the half of the product of the angle of the sector and the radius of the circle. It can be given as,
[tex]A_s=\dfrac{r^2\theta}{2}[/tex]
Here, (r) is the radius of the circle and θ is the angle of the sector. Multiply with π/180 to convert it into the degrees.
[tex]A_s=\dfrac{r^2\theta}{2}\left(\dfrac{\pi}{180}\right)\\A_s={\pi r^2}\left(\dfrac{\theta}{360}\right)[/tex]
Thus, the option D is correct. Now, πr² is the area of circle . Thus,
[tex]\rm \text{Area of sector}=\dfrac{(Area\; of \;Circle)(Arc\; Measure)}{360^o}\\\rm \dfrac{(Area\; of \;Sector)}{(Arc\; Measure)}=\dfrac{\text{Area of sector}}{360^o}[/tex]
From the following, which is NOT an equivalent expression to Area of sector is 2πrθ/360. Option A is correct.

A population in a town has 2500 people in the first month of its development. Every month after that, the population constantly increases 1.25 times from the previous month. What will the population of the town be in the 4th month?
A.) About 4883 people
B.) About 6104 people
C.) 12500 people
D.) 9375 people
Answer:
6104 people.
Step-by-step explanation:
1.25 means it will multiply by 1 and a fourth
2500*1.25 =3125 the first month
3125*1.25=3906.25 the second.
3906.25*1.25=4882.8125 the third
4882.8125*1.25=6103.515625
round that up and you have 6104 people.
Answer:
A) 4883Step-by-step explanation:
Given:
Initial number = 2500Rate of increase = 1.25 timesNumber of moths passed = 4 - 1 = 3Population is:
2500*1.25³ = 4882.8125 ≈ 4883Correct choice is A
1) Factorise 3x^2 + 5x + 2
2) Hence, solve x^2 + 5x + 2
Answer: (x+1)(3x+2) , i only got the answer for the first question, sorry!
Step-by-step explanation:
- factorise using AC method
AC= 3 x 2 = 6
find 2 numbers that add to give 5 and multiply to give 6 (3 and 2)
- put them as x in the equation to replace 5x
3x^2 + 2x + 3x + 2
- split the equation in half and expand each side
3x^2+2x | 3x+2
x(3x+2)+1(3x+2)
- put the numbers outside the brackets into a separate bracket
= (x+1)(3x+2)

3 x (2x - 3) -6x² = 6
Answer:
= − 2/3
Step-by-step explanation:
Distribute
3x(2x - 3)-6x² =6
6x² -9x-6x² =6
Combine like terms
6x² -9x-6x²=6
-9x=6
Divide both sides of the equation by the same term
-9x=6
-9x/-9=6/-9
Simplify
x=-2/3
Solution
x=-2/3
Answer:
Step-by-step explanation:
3 x (2x - 3) -6x² = 6
6 x^-9x-6x^=6
Combine like terms
6x^-9x-6x^=6
-9x=6
Divide both sides of the equation by the same term
− 9 = 6
-9x = 6
-9 -9

Answer:
68.50 in
Step-by-step explanation:
first we are given the width and the length for the rectangle and so we know that 4 × 5x + 7 = 128
so we would now solve for x:
4 × 5x + 7 = 128
= 4 × 5x = 121
= 20x = 121
= x = 6.05
now we can plug in 6.05 for x and find the perimeter:
5(6.05) + 4 = 34.25
5(6.05) + 4 = 34.25
34.25 + 34.25 = 68.50
