Answer:

12

Step-by-step explanation:

18 can be divided by 3 evenly making it 6. So there is 6 sets of 3 girls and 2 boys. So if you do 6 x 2 you get 12.

Circumference of the circle = 2 pie r

Therefore circumference = 2 × 22/7 × 6

So your circumference = 44pie mm

PEMDAS is an acronym that refers to the sequence of operations to be employed when solving equations with multiple operations. The value of the given expression (14-30)/2(-4) when simplified is 2.

PEMDAS is an acronym that refers to the sequence of operations to be employed when solving equations with multiple operations. PEMDAS is an acronym that stands for P-Parenthesis, E-Exponents, M-Multiplication, D-Division, A-Addition, and S-Subtraction.

The given expression can be simplified as shown below.

(14 - 30)/ 2 (- 4)

Using the rule of PEMDAS, solving parenthesis first,

= (14-30) / (-8)

= (-16)/ (-8)

Solving the division,

= 2

Hence, The value of the given expression (14-30)/2(-4) when simplified is 2.

Answer:

multiply 0.09 by 10 and that'd equal 0.09. A number 10 times greater then 0.009 is 0.09.

Answer: x - x1/ x2- x1 = y -y1 / y2-y1

x - 6/ -6-6= y - 1/ -1 -1

x -6/-12 = y -1 /-2

-2(x-6) = -12 (y-1)

-2x +12 = -12y +12

12y = 2x +12-12

y= 2x/12

The explicit formula for the sequence,

aₙ = 540(1/3)ⁿ⁻¹.

And the recursive formula for the sequence,

aₙ = aₙ₋₁(1/3).

A unique kind of sequence called a geometric sequence has a constant ratio between every two succeeding terms. This ratio is regarded as one of the geometric sequence's common ratios.

Given:

540, 180, 60, 20, ...

The sequence is a geometric sequence.

First, we find the common ratio.

180/540 = 1/3

60/180 = 1/3

20/60 = 1/3

Hence, 1/3 is the common ratio

r = 1/3

So,

the explicit formula for the sequence,

aₙ = 540(1/3)ⁿ⁻¹.

And the recursive formula for the sequence,

aₙ = aₙ₋₁(1/3)

Therefore, the formulae are given above.

Solution:

Triangles are shapes with three sides and three angles. Types of triangles are scalene, equilateral, isosceles triangles. Two triangles are similar if their corresponding sides have the same ratio and the angles of the two triangles are also equal.

Since the two triangles are similar, the ratio of their sides are equal, hence:

Solution

15/3 = (10 + x)/x              Cross multiply

15x = 3(10 + x)                Remove the brackets

15x = 30 + 3x                 Subtract 3x from both sides.

15x - 3x = 30                  Combine

12x = 30                         Divide by 12

x = 30/12
