solniwko [45]

Answer: A 24 cm piece of string is cut into two pieces , one piece is used to form a circle and the other piece is used to form a square.

How should this string be cut so that the sum of the areas is a minimum .

:  

Let x = the circumference of the circle

then

(24-x) = the perimeter of the square

:

Find the area of the circle

find r

2*pi*r = x

r =  

Find the area of the circle

A =  

A =  

A =  sq/cm, the area of the circle

:

Find the area of the square

A =  sq/cm the area of the square

The total area

At =  +  

Graph this equation, find the min

Min occurs when x=10.6 cm

cut string 10.6 cm from one end

Step-by-step explanation: Hope I help out alot (-: :-)

First you have to solve both inequalities,

3x-1>8

3x>9

x>3

and the other one

2x≤4

x≤2

then you graph each one on the number line

the graph says or, so the solution can satisfy either equation

the solution would be all real numbers except three

the way to write it is x≠3

find the smaller number of two consecutive odd numbers such that the sum of the larger numbers and twice the smaller number is 2
Contact [7]

Answer: 29

Step-by-step explanation:

Let the smaller number be x

Let the bigger number be x+2

The information given in the question can be represented in a equation as:

x + 2 + 2x = 4x - 27

3x + 2 = 4x - 27

4x - 3x = 27 + 2

x = 29

The smaller number is 29

How to do it ? Thanks for help

It is isosceles trapezium, so angle A=angle B,
angle C=angle D=angle BDC
triangle BCD,
180=22 +D+(D-88)
(D-88) because in trapezium C=D, angle BCD=ACD-88 or C-88, and D-88
180=2D-66
2D=180+66
2D=246
D=123
