Answer:

30cm

Step-by-step explanation:

Because of the polygon similarity postulate (PSP) 8/12=20/x

8/12=20/x

20/(8/12)=x

20*12/8=x

x=30 cm

The length of side x is 30 cm when the shapes below are mathematically similar.

To calculate the length of side x, we can use the concept of similarity between the shapes. When two shapes are mathematically similar, their corresponding sides are proportional.

8 cm corresponds to 20 cm

12 cm corresponds to x (unknown)

Using the concept of proportionality, we can set up the following equation:

(8 cm) / (20 cm) = (12 cm) / (x)

To find x, we can solve this equation:

Cross-multiplying:

8 cm * x = 20 cm * 12 cm

Simplifying:

8x = 240 cm²

Dividing both sides by 8 to isolate x:

x = 240 cm²/ 8

x = 30 cm

Therefore, the length of side x is 30 cm.

Answer:

69090840 possible rankings

Step-by-step explanation:

The number of possible ranking ordered in terms of effectiveness can be obtained using permutation

Number of salesperson = 39

Number of rank = 5

nPr = n! ÷ (n - r)!

nPr = 39P5

39P5 = 39! ÷ (39 - 5)!

39P5 = 39! ÷ 34!

39P5 = 39 * 38 * 37 * 36 * 35 = 69090840

The expressions that is equivalent to 3x - 5 are 2x - 4-1 + x and 3x+(-5)

From the given information, we need to calculate the expression that is equivalent to 3x - 5.

For the expression  2x - 4 - 1 + x

For the expression -x + x + x-1-1-1-1-1

2x - 5

For the expression 3x+(-5)

= 3x - 5

Hence the expressions that is equivalent to 3x - 5 are 2x - 4-1 + x and 3x+(-5)

Answer:

30

Step-by-step explanation:

Let the amount of money Taylor spent = x

The number of jeans she bought is 1-fith the amount of money she spent. She bought 6 jeans.

Hence

1/5 × x = 6 jeans

x/5 = 6 jeans

Cross Multiply

x = 5 × 6 jeans

x = 30

The amount of money Taylor spent = 30

Answer:

487?

Step-by-step explanation:

Answer:

(a)  12.96 ft²

(b)  21.5 in²

Step-by-step explanation:

(a) For the first diagram

Area of the shaded region (A) = Area of Tripezium- area of circle

A = [1/2(a+b)h]-[πr²]............... Equation 1

Where a and b are the parallel side of the tripezium respectively, h = height of the tripezium, r = radius of the circle.

From the diagram,

Given: a = 15 ft, b = 6 ft, h = 12 ft, r = h/2 = 12/2 = 6 ft.

Constant: π = 3.14

Substitute these values into equation 1

A = [12(15+6)/2]-(3.14×6²)

A = 126-113.04

A = 12.96 ft²

(b) For the second diagram,

Area of the shaded region (A') = Area of square- area of circle

A' = (L²)-(πr²)............. Equation 2

Where L = lenght of one side of the square, r = radius of the circle

From the diagram,

Given: L = 2r = (2×5) = 10 in, r = 5 in

Substitute these values into equation 2

A' = (10²)-(3.14×5²)

A' = 100-78.5

A = 21.5 in²

Answer:

Step-by-step explanation:

Given,

Number of rainy days = 18

Number of cloudy days = 14

Number of sunny days = 29

Therefore,

Number of days either sunny or cloudy = 14 + 29 = 43

So,

Number of more days sunny or cloudy than rainy are

= 43 - 18 = 25

Hence,

Option C 25 is the correct answer.

Answer:

2 10/16 or 2 5/8

Step-by-step explanation:

You can add the whole numbers first, so 1+1=2

Now add the remaining fractions: 5/16 +5/16=10/16.

2+10/16=2 10/16 or 2 5/8.

Answer:

y = (x + 1)(x - 0.586) ( x - 3.414)

Step-by-step explanation:

I sure wouldn't recommend doing this by trial and error.

I made a graph of which you can see. Every time this monster touches the x axis and speeds away upward is two equal roots of y. So the square root would be one of each of them.

y = (x + 1)^2 (x - 0.586)^2 (x - 3.414)^2

are the listed roots.

The square root is

y = (x + 1)(x - 0.586) ( x - 3.414)

Do I know that this is right? I don't. But I can tell you this: if you multiply 1^2 * (-0.586)^2 * (- 3.414)^2

you get 4 just as you should. Amazing that we have tools that do that sort of thing.

Answer:

JK is NOT tangent to the circle

Step-by-step explanation:

A tangent of a circle is a line that intersects a circle at one and only one point. For this reason, the radius will always intersect a tangent at a 90 degree angle to prove this single point intersection. From the triangle, we can introduce the Pythagorean theorem to see if the triangle is a right triangle:

a^2 + b^2 = c^2

48^2 + 14^2 = 36^2

2304 + 196 = 1296

2500 ≠ 1296

As this is not equal, the triangle is not a right triangle and therefore states that the tangent line does not intersect the radius at 90 degrees, meaning that it does not satisfy the requirements of a tangent line.
