Answer:

2 1/24

Step-by-step explanation:

2/3 =    16/24

3/4=      18/24

5/8=       15/24

16+18+15=49

49-24=  25-24=1

2 1/24

The formula for perimeter is P = 2length + 2width (P = 2L + 2W)

You know that the length is 4 more yards then twice the width. In equation form this would be:

length = 4 + 2w

Plug what you know into the perimeter formula:

26 = 2(4 + 2w) + 2w

First you must distribute the 2 to the numbers inside the parentheses, which would be 4 and 2w...

26 = (2 * 4) + (2 * 2w) + 2w

26 = 8 + 4w + 2w

Now you must combine like terms. This means that first numbers with  the same variables (w) must be combined...

26 = 8 + 4w + 2w

4w + 2w = 6w

26 = 8 + 6w

Now bring 8 to the left side by subtracting 8 to both sides (what you do on one side you must do to the other). Since 8 is being added on the right side, subtraction (the opposite of addition) will cancel it out (make it zero) from the right side and bring it over to the left side.

26 - 8 = 8 - 8 + 6w

18 = 0 + 6w

18 = 6w

To isolate w divide 6 to both sides

18 / 6 = 6w / 6

w = 3

We know that the width is 3 ft

Now you must find the length. To do this plug 3 where you see w in the equation:

length = 4 + 2w

l = 4 + 2(3)

l = 4 + 6

l = 10

We know that length is 10 ft

Letter B. is the correct answer

Answer:

16

Step-by-step explanation:

We use the completing square method to find make the expression a perfect square.

(b/2)²=ac where a and b are coefficients of x² and x respectively while c is a constant.

= (-8/2)²=16

We add 16 to both sides and the expression becomes a perfect square.

Step-by-step explanation:

Answer:

Diameter: 4

Radius: 2

Equation: ( x-3 ) + ( y + 2) = 4

Final answer:

The length of the diameter is 4 units, the radius of the circle is 2 units, and the equation of the circle, with its center at (3,-2), is (x - 3)² + (y + 2)² = 4.

Explanation:

The diameter of a circle is the distance between two points on the circumference of the circle which pass through the center of the circle. The two points given are (5,-2) and (1,-2), which both lie on a horizontal line since their y-coordinates are the same. To find the length of the diameter, you calculate the distance between these two points using the distance formula:

d = √((x2 - x1)² + (y2 - y1)²)

For these points, it becomes:

d = √((1 - 5)² + (-2 - (-2))²) = √((-4)² + (0)²) = √(16) = 4

Therefore, the length of the diameter of the circle is 4 units.

To find the radius of the circle, which is half the diameter, divide the diameter by 2:

r = d / 2 = 4 / 2 = 2 units

The equation of a circle in the standard form is (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius. Given that the center is the midpoint between (5,-2) and (1,-2), which is (3,-2), the equation of the circle with a radius of 2 would be:

(x - 3)² + (y + 2)² = 2²

(x - 3)² + (y + 2)² = 4

Answer: 75

Step-by-step explanation:

The area formula for a trapzoid is area= 1/2 (a+b) h

In this equasion, the substitution would be area=1/2 (10+15) 6

Following PEMDAS, enter the numbers within the parenthases (10+15)

Divide the 25 in half, then multiply by 6. This comes out to 75.

For this case we have that by definition, the area of a trapezoid is given by:

[tex]A = \frac {1} {2} (B + b) * h[/tex]

Where:

B: It is the major base

b: It is the minor base

h: It's the height

According to the figure we have the following data:

[tex]B = 15ft\\b = 10ft\\h = 6ft[/tex]

Substituting in the formula:

[tex]A = \frac {1} {2} (15 + 10) * 6\\A = \frac {1} {2} (25) * 6\\A = \frac {1} {2} 150\\A = 75[/tex]

Finally, the area of the trapezoid is[tex]75ft ^ 2[/tex]

Over  the complex number, this is equal to

(a-bi) (a+bi)

(4x -3yi) (4x+3yi)

Answer:

(4x -3yi) (4x+3yi)

Step-by-step explanation:

The expression 16x^2 + 9y^2 is a sum of squares, and it can be factored over the complex numbers using the difference of squares formula:

a^2 + b^2 = (a + bi)(a - bi)

In your expression:

a = 4x

b = 3y

So, applying the difference of squares formula:

16x^2 + 9y^2 = (4x + 3yi)(4x - 3yi)

This is the factored form of the expression 16x^2 + 9y^2 over the complex numbers.

Answer:

64

Step-by-step explanation:

Volume of a cube is:

V = s³

When s = 8 in:

V = (8 in)³ = 512 in³

When s is doubled (s = 16 in):

V = (16 in)³ = 4096 in³

Now we can write a proportion:

8 mugs / 512 in³ = x mugs / 4096 in³

x = 64

The maximum number of mugs that the larger box can hold is:

                                     64

The edge length of box is:  8 inches.

This means that the volume of box is: 8×8×8=512 cubic inches.

Also, the number of mugs a box of edge length 8 in. can hold is: 8

Hence, volume of 1 mug= Volume of box/Number of mugs

Volume of 1 mug= 512/8=64 cubic inches

Now, if the dimension of the box is doubled.

This means that the Volume of new box= 8×Volume of old box

Volume of new  box=8×512=4096 cubic inches

Let n be the number of mugs that the new box can hold.

Volume of new box=n×Volume of  1 mug

⇒   4096=n×64

⇒   n=4096/64

⇒  n=64

               Hence, the answer is:

                            64

Answer:

k = 10

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.

∠ZYM is an exterior angle and

∠YZX and ∠ZXY are the 2 opposite interior angles, hence

4k + 5 + 6k + 10 = 115

10k + 15 = 115 ( subtract 15 from both sides )

10k = 100 ( divide both sides by 10 )

k = 10

For the sake of showing work I will replace the empty space with an x like so...

[tex]\frac{9}{10} =\frac{90}{x}[/tex]

To find out what x is you must cross multiply (aka butterfly)

***Image of this step is attached below

9*x = 10*90

9x = 900

Next divide 9 to both sides to finish isolating x. Since 9 is being multiplied by x, division (the opposite of multiplication) will cancel 9 out (in this case it will make 9 one) from the left side and bring it over to the right side.

9x ÷ 9 = 900 ÷ 9

1x = 100

x = 100

To make these fractions equivalent the empty spot must be 100

[tex]\frac{9}{10} = \frac{90}{100}[/tex]

Your question asks to find what was the size of the population in 2017

In order to solve this problem, we're going to need to use the given information in the question in order to find the population in 2017.

Key information:

In 2010, population was 6500

In 2014, population increased by 10% from 2010

In 2017, population decreased by 6% from 2014.

With the information above, we can solve the problem.

We're going to start with 6500 as our starting population.

We know that the population increased by 10% in 2014, so we would multiply 6500 by 1.10.

[tex]6500*1.10=7,150[/tex]

The population in 2014 was 7,150.

We know that in 2017, the population decreased by 6% from the population in 2014. So we would find how much 6% is from 7,150 and then subtract that number.

[tex]7,150*.06=429\\\\7,150-429=6,721[/tex]

When you're done solving, you sohuld get 6,721.

The population in 2017 would be 6,721.

Answer:

-23

Step-by-step explanation:

Check the picture below.

so, two tangents to the same circle, whenever they meet outside the circle, they'll be congruent, namely, AB = AX and CB = CY and DX = DY.

well, we know AB = BC, and we know that AB = AX and CB = CY, therefore

AB = BC = AX = CY = 10.

an isosceles needs twin sides, well, we know DX = DY, and we know that AX = 10 then the triangle's side AD = AX + DX = 10 + DX.

the triangle's side of CD = CY + DY = 10 + DY.

but but but, we know DX and DY are tangents to a common circle meeting outside, so they're equal, so whatever length DX and DY are, is the same, so

10 + DY = 10 + DX

meaning the triangle's sides AX = CD, and for an isosceles, is all you need, twin sides.

Answer: c. getting heads on a coin toss and rolling a 5 on a die

Answer:

The solution set is {1, -2/3, 2/3}.

Step-by-step explanation:

81m^3-81m^2-36m+36=0

9(9m^3 - 9m^2 - 4m + 4) = 0

Looks  like 1 might be  one root:

f(1) = = 9*1 - 9*1 - 4*1  + 4 = 0  so one factor is (x - 1).

Divide the function  by x - 1:

        9m^2 - 4  <------------------Quotient

        ----------------------------------

m - 1 ) 9m^3 - 9m^2  - 4m + 4

         9m^3-9m^2

         -----------------------

                       -4m + 4

                        -4m + 2

                         ..............

Now :

9m^2 - 4 = (3m - 2)(3m + 2).

so  m - 1 = 0  or 3m - 2 = 0 or 3m + 2 = 0

m = 1 , 2/3,  -2/3.

Answer:

There are 13 different ways to finish the race

Step-by-step explanation:

To identify the number of different ways to finish the race we should categorized the types of win:

1. Without tie: the ways that are possible in this option are defined by the rule of multiplicación. There are 3 participants and 3 places, there are 3 possibles participant that can occupy the first place, then 2 possibles participants that can occupy the second place and one participant that can occupy the last place.

       3               x          2                x          1                  =   6

first place              second place           third place

So, there are 6 different ways to win without tie.

2. Double tie in the second place: This time there are 3 participant that can occupy the first place and the other participant are going to occupy the second place. So there are only 3 ways in this option, every option is defined by the winner. that's mean: the winner is Alfred, or is Brandon or  is Charles.

3. Double tie in the first place: This option is like option 2, there are only 3 ways because every option is defined by the person that is in the second place. That's mean: the second place is occupy by Alfred, or by Brandon or by Charles.

4. All the participants end in tie: There are just one possibility in this option, all are the winners.

Finally there are 13 ways to end this race, 6 ways without tie, 3 ways with double tie in second place, 3 ways with double tie in first place and 1 way with all the participants in the same place.

Final answer:

Alfred, Brandon, and Charles can finish the race in 13 different ways, considering the possibilities of no ties, two-way ties, and a three-way tie. This is calculated by adding 6 permutations for no ties, 6 combinations for two-way ties, and 1 possibility for a three-way tie.

Explanation:

We need to calculate in how many different ways Alfred, Brandon, and Charles can finish a race given that there is the possibility of a tie. There are three scenarios to consider for the finishes: no ties, two-way ties, and a three-way tie.

No ties: This is a simple permutation of 3 participants, which gives us 3! (3 factorial) ways to finish, or 3 x 2 x 1 = 6 ways.

Two-way ties: For the two-way tie, we have 3 possible pairs (Alfred & Brandon, Alfred & Charles, Brandon & Charles), and for each pair, there is one person who does not tie, resulting in 2 finishing orders per pair, so 3 pairs x 2 orders = 6 ways.

Three-way tie: There is only 1 way that all three can tie.

Adding up the possibilities from each scenario, we get 6 (no ties) + 6 (two-way ties) + 1 (three-way tie) = 13 different ways they can finish the race.

By the zero product property;

[tex]\sin x=0[/tex] or [tex]\sin x-1=0[/tex]

For [tex]\sin x=0[/tex], the general solution is [tex]x=n \pi[/tex]

[tex]\sin x-1=0[/tex], [tex]\sin x=1[/tex], the general solution is [tex]x=2\pi n+\frac{\pi}{2}[/tex]

[tex]x=n \pi[/tex] or [tex]x=2\pi n+\frac{\pi}{2}[/tex]

The solutions to the equation sin(x)(sin(x)-1) = 0 are:

x = 0, π, 2π, 3π, π/2, 3π/2, 5π/2, and so on.

We have,

To solve the equation sin(x)(sin(x)-1) = 0, we can apply the zero-product property, which states that if a product of factors is equal to zero, then at least one of the factors must be equal to zero.

So, we set each factor equal to zero and solve for x:

sin(x) = 0

To find the solutions for this equation, we look for x values where the sine function equals zero.

The solutions are x = 0, π, 2π, 3π, and so on.

sin(x) - 1 = 0

Adding 1 to both sides:

sin(x) = 1

The solutions for this equation occur when the sine function equals 1, which happens at x = π/2, 3π/2, 5π/2, and so on.

Therefore,

The solutions to the equation sin(x)(sin(x)-1) = 0 are:

x = 0, π, 2π, 3π, π/2, 3π/2, 5π/2, and so on.
