kherson [118]
Given the question "six people went into the woods to look for truffles. On average they collected 7 truffles per person. The average of the last four people to come back was 8 truffles per person. In fact the fourth person to come backk had 11 treuffles in is basket. How many truffles did the last three people collect altogether?" Since the average truffles collected by the six people is 7, then the total truffles collected by the six people is 6 x 7 = 42 truffles. Since the last four people that came back collected an average of 8 truffles, then the total number of truffles collected by the last four people that came back is 4 x 8 = 32 truffles. Given that the fourth person collected 11 truffles, therefore, <span>the last three people collected a total of 32 - 11 = 21 truffles.</span>

Find the radius and diameter of a circular puddle whose
o-na [289]

Answer:

r = 35cm

Step-by-step explanation:

Given

C = 220cm

\pi = \frac{22}{7}

Required

Determine the radius

Circumference (C) is calculated as:

C = 2\pi r

Where r represents radius

Substitute values for C and \pi

220cm = 2 * \frac{22}{7} * r

220cm =  \frac{44}{7} * r

Multiply through by 7/44

\frac{7}{44} * 220cm =  \frac{7}{44} * \frac{44}{7} * r

r = \frac{7}{44} * 220cm =

r = \frac{7 * 220cm }{44} =

r = \frac{1540\ cm}{44}

r = 35cm

<em>Hence, the radius is 35cm</em>

The sum of the digits of a two-digit number is 12. The number formed by reversing the digits is 54 more than the original number
andreyandreev [35.5K]

Answer:

39

Step-by-step explanation:

let the 2 digit number be ab = 10a + b ( considering place value )

The reversed  2 digit number is ba = 10b + a

The sum of the 2 digit number is

a + b = 12 ( subtract b from both sides )

a = 12 - b → (1)

Expressing as an equation

ba = ab + 54 , that is

10b + a = 10a + b + 54

Substitute a = 12 - b into the equation

10b + 12 - b = 10(12 - b) + b + 54 , simplify both sides

9b + 12 = 120 - 10b + b + 54

9b + 12 = - 9b + 174 ( add 9b to both sides )

18b + 12 = 174 ( subtract 12 from both sides )

18b = 162 ( divide both sides by 18 )

b = 9

Substitute b = 9 into (1)

a = 12 - 9 = 3

Thus

the original 2 digit number = ab = 39

The reversed 2 digit number = ba = 93

which is 54 more than the original number
