1/3 rd part of the length of a bamboo is coloured in red and 1/5th part of it is coloured green and the remaing is 14m is colour

aksik [14]

$\bold{\huge{\blue{\underline{ Solution }}}}$

$\bold{\underline{ Given :- }}$

1/3rd part of the length of a bamboo is coloured with red and 1/5th part of it is coloured with green and the remaining is 14m is coloured with yellow.

$\bold{\underline{ To \: Find :- }}$

We have to find the total length of the bamboo

$\bold{\underline{ Let's \: Begin :- }}$

Let the total length of bamboo be x

According to the question, 

$\sf{\dfrac{ 1}{3}}{\sf{x +}}{\sf{\dfrac{ 1}{5}}}{\sf{x + 14 = x }}$

$\sf{\dfrac{ 1}{3}}{\sf{x + }}{\sf{\dfrac{1}{5}}}{\sf{x = x - 14 }}$

$\sf{\dfrac{5x + 3x}{15}}{\sf{ = x - 14 }}$

$\sf{ 5x + 3x = 15( x - 14 )}$

$\sf{ 8x = 15x - 210 }$

$\sf{ 210 = 15x - 8x}$

$\sf{ 7x = 210 }$

$\sf{ x = }{\sf{\dfrac{ 210}{7}}}$

$\sf{\red{x = 30\: m}}$

Hence, The total length of the bamboo is 30m.

A hot tub has capacity of 1458 liters 487 liters and 750 ml were put in how much more needs to be put in

Colt1911 [192]

Well the easiest way we can do it is convert liters in to milliliters and since there are 1000 milliliters in a liter multiply 1458 by 1000 and 487 by 1000 which will get you 1458000 milliliters of capacity and the 487 liters turns into 487000 mililiters we add this to the 750 milliliters to get 487750 milliliters. Now it is all a matter of subtracting to find out how much more needs to be put in. 1458000-487750=970250 milliliters. So the amount needed to fill the hot tub is 970250 ml or if you want to convert it back to liters 970.250 l
