7n²-65n+72 splitting

Answer»

hi first we need to MULTIPLY 7 * 72 = 504

deference between this two NUMBERS is 72 - 5 = 65;


now we can start the splitting

7n²-65n+72;

7n²+ 7n - 72N + 72;

now take the common 7n

7n(n + 1) - 72(n + 1)=0;

7n-72=0; n + 1 =0;

7n = 72; n = -1;

n = 72/7; n= -1

Someone made a temporary water reservoir with a length of 130 cm, width 90 cm, and a depth of 70 cm. If the thickness of the baton bath is 5 cm, how many liters of volume of shelter when the water is full?

Answer»

// l = long


W = width


h = high


V = volume //



// unit conversion


1 LITER = 1.000cm³


1 cm³ = 1 / 1.000liter //



l water = l tub - w concrete - w concrete


= 130cm - 5CM - 5cm


= 120cm



w water = w tub - w concrete - w concrete


= 90cm - 5cm - 5cm


= 80CM



h water = h bak - w concrete // only in less 1 times because the tub is generally not closed


= 70cm - 5cm


= 65cm



V water = l water × w water × t water


= 120cm × 80cm × 65cm


= 9.600cm² × 65cm


= 624.000cm³


= 624,000 (1 / 1,000liter)


= 624 liters



So the volume of water is 624 liters

it takes six days for two men and three women working together to complete a work. three men would do the same work five days sooner than nine women. how many times does the output of a man exceed that of a woman?

Answer»

Given:

It takes six days for two men and three women working together to complete a work. three men would do the same work five days sooner than nine women.  

To FIND:

How many TIMES does the output of a man exceed that of a woman?

SOLUTION:

From given, let us consider the FOLLOWINGS:

If 9 women, 1-day work = 1/x ---(1)

So 3 men, 1 day work = 1/(x-5) ---(2)

Also given 3 women and 2 men 1-day work = 1/6 ---(3)

From (1), we have,

3 women 1-day work = 1/3x

From (2), we have,

2 men 1 day work = 2/[3(x-5)]

Equation (3) can be represented as, 1/3x + 2/[3(x-5)]= 1/6

Solving the equation, we GET, x = 10

So 1 woman 1 day work=1/(9 × 10)= 1/90 and

1 man 1 day work=1/3(10-5)= 1/15

The output of men exceeds that of a women = (1/15)/(1/90)= 6 times

Therefore, 6 times the output of a man exceeds that of a woman

ATQ
X+3X+5 = 221
4X+5 = 221
4X = 221 - 5
4X = 216
X = 216/4
X = 54

Trees planted be section A = 3X+5
= 3× 54 + 5
= 167
