KLMN is a trapezoid where KL=MN and m∠1=m∠2 . It is also given that LM:KN = 8/9 and PKLMN=132.The midsegment is 34 units long.

The trapezoidal shape KLMN, where KL = MN.

m∠1=m∠2

Moreover, LM/KN = 8/9

Additionally, KLMN's perimeter is 132 units.

The midsegment's size (KM).

We can see that in the above case, KM is a transversal in relation to the parallel lines LM and KN. which implies,

∠KML=∠MKN

∠1=∠2

Two base angles are clearly equal. So, KLM and KMN are isosceles triangles.

Using the side ratios of two triangles as an example,

= KL: LM: MN: KN

= 8 : 8 : 8 : 9

The ratio units add out to 8 + 8 + 8 + 9 = 33. Consequently, each ratio's value is,

=[tex]\frac{perimeter}{33} \\\\\frac{132}{33} \\\\=4[/tex]

The segment LM's length is thus,

LM=8×4=32

Additionally, section KN's length is

KN=9×4=36

Taking the average of LM and KN as, one can then determine the length of the midsegment KM.

[tex]KM=\frac{LM+KN}{2} \\\\\\KM=\frac{32+36}{2}[/tex]

KE=34

As a result, the midsegment is 34 units long.

Samantha used 120 grams of 25% sugar syrup.

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, Samantha mixes some amount of 25% sugar syrup with x grams of 10% sugar syrup. The result is 120 grams of 15% sugar syrup.

Let Samantha used y grams of 25% sugar syrup.

Then, she used (120 - y) grams of 10% sugar syrup.

We know that the final concentration of sugar syrup is 15%, which means that 15% of the total 120 grams of the syrup is sugar.

This can be expressed as:

0.15 x (y + (120 - y)) = 0.15 x 120

Expanding and simplifying the equation, we get:

0.15y + 0.15 x 120 - 0.15y = 18

0.15 x 120 = 18

Solving for y, we get:

y = 120 x 18 / (0.15 x 120)

= 120 x 18 / 18

= 120.

Hence, Samantha used 120 grams of 25% sugar syrup.

For the given height function h(t)= -16t²+88t the rocket is in the air for 5.5 seconds.

Height of the launched rocket is equal to :

h(t)= -16t²+88t

Time is represented by 't' in seconds after launch

'h' represents the height of the rocket.

For how long time rocket is in the air :

h(t) = 0

⇒  -16t²+88t = 0

⇒ t ( -16t+88 ) = 0

⇒ t = 0 or ( -16t+88 ) = 0

value of time 't' cannot be equal to zero.

This implies ( -16t+88 ) = 0

⇒16t = 88

⇒ t = 88 / 16

⇒ t = 5.5 seconds

Therefore, the time for which rocket is in the air as per given height function is equal to 5.5 seconds.

Answer:

Step-by-step explanation:

You want the value of x that makes f(x) = 60, when f(x) is the exponential function with an initial value of 100 and a decay factor of 0.95.

The form of an exponential function is ...

  f(x) = (initial value) · (decay factor)^x

For the given initial value and decay factor, the function is ...

  f(x) = 100 (0.95^x)

Solving for x, we find ...

  f(x)/100 = 0.95^x

  log(f(x)/100) = x·log(0.95)

  x = log(f(x)/100)/log(0.95)

For f(x) = 60, the value of x is about ...

  x = log(60/100)/log(0.95) ≈ 9.959

The value of x is about 9.959.

The sides and angle of the right triangle are as follows:

A right angle triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.

Therefore, the side of the triangle can be found using trigonometric ratios as follows:

Hence,

tan 5 = opposite / adjacent

tan 5 = 5 / b

b = 5 / tan 5

b = 57.1506949525

Hence,

b = 57.2 units

sin 5 = opposite / hypotenuse

sin 5 = 5 / c

c = 5 / sin 5

c = 57.3685943662

c = 57.4 units

In the first hour:

The farmer sells 8% of the total chickens:

         [tex]= \frac{8}{100}[/tex]×[tex]250[/tex]

         = 20 chickens

Therefore, the number of chickens left are:

= (250 - 20) chickens

= 230 chickens

In the second hour:

The farmer sells 10% of the chickens left:

= [tex]\frac{10}{100}[/tex]×[tex]230[/tex]

= 23 chicken

∴ The total number of chickens sold in the two hours = (20 + 23) chickens

                                                                                      = 43 chickens

43 has to be expressed as a percentage of the original number (i.e. 250)

Length of AD is, 2.5 inches

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

Values are,

AB = 18 inches,

AE = 5 inches,

CE = 6 inches,

Let the length of ED = x

Now, By the figure,

⇒ ΔABD ≈ ΔECD

Hence, By definition of proportional we get;

⇒ AB / AD = EC / ED

⇒ AB / (AE + ED) = EC / ED

⇒ 18 / (5 + x) = 6 / x

⇒ 3x = 5 + x

⇒ 3x - x  =5

⇒ 2x = 5

⇒ x = 2.5 inches

The surface area of the right triangular prism with legs of 5 centimeters and 12 centimeters, a hypotenuse of 13 centimeters, and a height of 2 centimeters is 108 square centimeters.

Surface area refers to the total area of the surface of a three-dimensional object. When it comes to a right triangular prism, the surface area includes the area of all six faces.

Let's call the height of the triangular prism "h" and label the legs of the triangle "a" and "b". Using these values, we can find the area of the base of the triangular prism. The area of a right triangle is equal to 1/2 times the product of the legs, so the area of the base is

=> (1/2) * a * b = (1/2) * 5 * 12 = 30 square centimeters.

Next, we need to find the surface area of each of the three lateral faces. Each of these faces is a rectangle, so we can find the area by multiplying the height of the prism by the length of one of the sides of the triangle base.

The length of one side of the triangle base is equal to the hypotenuse, which is 13 centimeters. So, the surface area of each of the three lateral faces is

=> h * 13 = 2 * 13 = 26 square centimeters.

Finally, we can find the total surface area by adding the surface area of the base and the surface area of the three lateral faces.

The surface area of the base is 30 square centimeters, and the surface area of each lateral face is 26 square centimeters, so the total surface area is

=> 30 + 3 * 26 = 30 + 78 = 108 square centimeters.

Given that x, y, z are different and satisfy the equations:

x^3 + x^2 - x = 0

y^3 + y^2 - y = 0

z^3 + z^2 - z = 0

We can multiply the first equation by y, the second by z, and the third by x to obtain:

x^3y + x^2y - xy = 0

y^3z + y^2z - yz = 0

z^3x + z^2x - zx = 0

Adding these three equations together, we get:

x^3y + x^2y - xy + y^3z + y^2z - yz + z^3x + z^2x - zx = 0

Expanding and simplifying, we find that:

x^2y + xy^2 + y^2z + yz^2 + z^2x + zx^2 - xy - yz - zx = 0

Now, we use the fact that x, y, and z are roots of the equations given above to simplify the expression further:

x^2 - x + y^2 - y + z^2 - z = 0

We can also write this as:

(x - 1)(x + 1) + (y - 1)(y + 1) + (z - 1)(z + 1) = 0

This expression can be factorized as:

(x - 1)(x + 1)(y - 1)(y + 1)(z - 1)(z + 1) = 0

Since x, y, and z are all different, we have that:

(x - 1)(x + 1) ≠ 0

(y - 1)(y + 1) ≠ 0

(z - 1)(z + 1) ≠ 0

Therefore, we have:

(x - 1)(x + 1)(y - 1)(y + 1)(z - 1)(z + 1) = (x - 1)(x + 1)(y - 1)(y + 1)(z - 1)(z + 1) = 0

The smallest possible value for a term in the five-term arithmetic sequence is 1.The sum of a five-term arithmetic sequence is given as 100 and all terms are positive integers. Let's call the first term "a" and the common difference "d".

The five terms can be represented as a, a + d, a + 2d, a + 3d, and a + 4d. The sum of these five terms is 100, which can be represented as:

a + (a + d) + (a + 2d) + (a + 3d) + (a + 4d) = 100

Simplifying the expression, we get:

5a + 10d = 100

Dividing both sides by 5, we get:

a + 2d = 20

Since all terms are positive integers, it follows that "a" and "d" must also be positive integers. The smallest possible value for "a" is 1, and the smallest possible value for "d" is 1. Substituting these values into the expression for "a + 2d" yields:
