Remark

There is only 1 way that you can get 1 2 3 4 5 in that order.

There are many possibilities of drawing 5 numbers from a total of 9 possible ones.

Total number of drawing 5 numbers.

Total = 9 * 9 * 9 * 9 * 9

Total = 59049

So putting the two facts together you get

Chance of getting (1 2 3 4 5)  = 1/59049

Answer:

12 inchis

Step-by-step explanation:

In the provided figure of line segment RS, the statement which is true is su + ut = rt. Option A is correct.

Length of a line segment is the distance of both the ends of it.

The length of the line segment TU is 6 units.

[tex]TU=6\rm\; units[/tex]

In the figure attached below, the length of line segment RT is 12 and RS is 24. Thus, the value of RS is double than the value of RT.

[tex]RT=2RS\\RS=\dfrac{RT}{2}[/tex]

RS is the total length of the segment, which is equal to the length of RT and ST.

[tex]RT+ST=24\\12+(SU+UT)=24\\(SU+UT)=24-12\\SU+UT=12[/tex]

12 is the length of RT. Thus,

[tex]SU+UT=RT[/tex]

Hence, in the provided figure of line segment RS, the statement which is true is su + ut = rt. Option A is correct.

Answer:

Cora worked 3 hours

Step-by-step explanation:

104 = 18x + 50 ( x = # of hours worked)

54 = 18x   ( subtracted 50 from both sides)

3 = x    ( divided both sides by 18)

F(51)

===========================================================

Explanation:

The very large numbers are likely put there as a distraction. They aren't needed. Adding any two adjacent Fibonacci numbers will lead to the next term in the sequence. This is simply based on how the special number sequence is defined or set up.

This means F(49)+F(50) = F(51) i.e. adding the 49th and 50th terms will generate the 51st term.

In general,

F(n) + F(n+1) = F(n+2)

where n is a positive integer.

m=riserun=ΔyΔx

m=y2−y1x2−x1

m=−9−37−2

m=−125

m=−125

In decimals:

Answer:

x = 0.86

Step-by-step explanation:

(3x - 1)(x + 6) = 3.14159 × (x + 1)²

Answer:

2.6 inches

As shown in the title if length is x,

8 * 1 = 3x

x = 8/3 in

= 2.6 in

The new length of the rectangular print will be 2.68 feet.

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Given a rectangular print with dimensions,

Length = 1 foot = 12 inches

Width = 8 inches.

Area = 12(8) = 96 square inches

Now,

The area of the new print should be the same

So,

96 = Length × 3

Length = 32 inches = 2.67 feet.

Hence "The new length of the rectangular print will be 2.68 feet".

Answer:

? = 49

Step-by-step explanation:

To solve this we just need to understand that when A=1, B=7. So when the side for a is 7 that is basically multiplying A by 7 so we have to do the same to the B side. So when the B side is multiplied by 7 it would be 7*7 =49 so the ? is equal to 49 when that similar side is equal to 7.

This is all based on the fact that the two triangles must be similar triangles.

if the diameter is 8, then its radius is half that or 4.

Step-by-step explanation:

The measure of the angle ABC in the given circle is 60°

A circle is the set of all points in the plane that are a fixed distance (the radius) from a fixed point (the center). Any interval joining a point on the circle to the center is called a radius. By the definition of a circle, any two radii have the same length.

Given is a circle, with arcs DE and AC measuring 45° and 75° respectively,

We need to find the measure of the angle ABC,

So, using the property of a circle, we will have,

∠ ABC = 1/2 {arc DE + arc AC}

= 1/2 {45+75}

= 1/2 x 120

= 60

Hence, the measure of the angle ABC in the given circle is 60°

1. Thomas Edison used "perspiration" to refer to the physical and mental efforts needed to achieve a meaningful purpose in any human endeavor.

2. As it applies to businesses, it is not enough to develop a business idea or plan, as the business person must be prepared to execute and carry the business idea or plan to fruition.

According to Thomas Edison, the superior intellect or creativity we associate with great minds comes from inspiration (the idea) and perspiration (hard work).

Perspiration literarily refers to the sweat that emanates as someone works hard.

Without a strong working ethic, it will be impossible to achieve great results from only the proposition of great ideas or business plans.
