Answer:

There are 600 students in this school.

Step-by-step explanation:

Let p represent the total population of the school.

Then (1/3)p represents the number of students who like math.  Subtracting this (1/3)p from p gives an expression representing those who do not like math:  

p - (1/3)p = (2/3)p

400 students do not like math, so (2/3)p = 400.

Solve this for p by multiplying both sides by (3/2):

(3/2)(2/3)p = (3/2)(400), which simplifies to p = 600.

There are 600 students in this school.

The Toolkit function that has a start and end number for the range and is also cyclic is ; The constant Function ( i.e. f(x) = a )

There are about (9) toolkit functions and some of these toolkit functions :

The common characteristics between the various toolkit functions is that they all have undefined domains ( i.e. ( - ∞ , ∞ ) or ( -∞, 0 ), and undefined ranges as well.  while the only Toolkit function with a defined range is the Constant function { a, a }

The range for a Constant function starts and ends with the value of the given constant. i.e. { a, a }. while other functions have undefined range values.

Hence we can conclude that the Toolkit function with a start and end number for the range is the Constant function.

Answer:

The answer Is A 1 1/5 < -2 2/5

Step-by-step explanation:

It says that this statement is true because 1 1/5 is to the left of -2 2/5 on the number line but it is actually to the right because -2 2/5 is negative while 1 1/5 is positive therefore making it larger and the correct statement would be that    1 1/5 > -2 2/5

Answer:

X equals 8.

Step-by-step explanation:

The polygon in the question has 5 sides. However, it is an irregular polygon hence the sides are given as 62 degrees, 66 degrees, 77 degrees, 59 degrees and 12X degrees.

The size of the exterior angle of a polygon is calculated as

Angle = 360/n

Where n is the number of sides. So for a five sided polygon, the size of the exterior angle is calculated as

360/5 which equals 72. Since it is an irregular polygon, the sum of the exterior angles can be expressed as

62 + 66 + 77 + 59 + 12X = 360

264 + 12X = 360

Subtract 264 from both sides of the equation

12X = 96

Divide both sides of the equation by 12

X = 8

The value of x in the given polygon is 8.

A polygon is a plane figure made up of line segments connected to form a closed polygonal chain

The polygon in  has 5 sides.

It is an irregular polygon hence the sides are given as 62 degrees, 66 degrees, 77 degrees, 59 degrees and 12X degrees.

The size of the exterior angle of a polygon is calculated as

Angle = 360/n

Where n is the number of sides.

So for a five sided polygon, the size of the exterior angle is calculated as

360/5 =72.

Since it is an irregular polygon, the sum of the exterior angles can be expressed as

62 + 66 + 77 + 59 + 12X = 360

264 + 12X = 360

12X = 96

Divide both sides of the equation by 12

X = 8

Hence, the value of x in the given polygon is 8.

A polygon with 5 sides is shown with its exterior angles. The exterior angles are 62 degrees, 66 degrees, 77 degrees, 59 degrees, and (12 x) degrees. What is the value of x? 6 8 10 12

Answer:

10, 20, 40

scale factor = x2

10, 20, 40, 80, 160, 320, 640, 1280, 2560, 5120, 10240

answer = 10,240

Answer:

10,240

Step-by-step explanation:

First, we find the constant ratio by dividing a number by the previous number.

r = 40/20 = 2

Now we apply the formula for term a_n of a geometric sequence.

a_n = a_1 * r^(n - 1)

a_11 = 10 * 2^(11 - 1)

a_11 = 10 * 2^10

a_11 = 10,240

Answer:

No solutions for n

Step-by-step explanation:

Distribute the 4 to the -8 and the 2n

-4 + 4*-8 + 4*2n = -37 + 8n

Multiply

-4 - 32 + 8n = -37 + 8n

Subtract 8n on both sides

-4 - 32 = -37

Subtract on the left

-36 = -37

No solutions because -36 does not equal -37

Answer:

No solution

Step-by-step explanation:

-4 + 4(-8 + 2n) = -37 + 8n

-4 - 32 + 8n = -37 + 8n

-36 + 8n = -37 + 8n

8n - 8n = -37 + 36

0 = -1

Since 0 does not equal 1, this is a “No Solution”
