The ideal mass for a piece of chocolate is 2.5 ounces. The actual mass for a production can vary by, at most, 0.08

Nady [450]

Answer:

$2.42\,oz \leq m_{real} \leq 2.58\,oz$

Step-by-step explanation:

The inequality must be the absolute value of the difference between real mass and ideal mass less or equal to 0.08 ounces. That is to say:

$|m_{real} - m_{ideal}| \leq 0.08\,oz$

$|m_{real} - 2.5\,oz| \leq 0.08\,oz$

There are two extreme cases:

$m_{real,max} - 2.5\,oz = 0.08\,oz$ and $m_{real, min} - 2.5\,oz = -0.08\,oz$

$m_{real, max} = 2.58\,oz$ and $m_{real,min} = 2.42\,oz$

Range of chocolate masses must be:

$m_{real, min} \leq m_{real} \leq m_{real,max}$

$2.42\,oz \leq m_{real} \leq 2.58\,oz$

Ben is 12 years older than Ishaan. Ben and Ishaan first met two years ago. Three years ago, Ben was 4 times as old as Ishaan.

Nitella [24]

Let x be the age of ishaan so the age of ben will be 12+x. the equation will become x=x+12
Going 3 years back, the age of ishaan was x-3 so that of ben would be x+12-3 before 3 years. at that time the age of ben was 4 times the age of ishaan. it means x+12-3(the age of ben)=4(x-3(the age of ishaan))
solving this equation, we get the answer x=7. this is the age of ishaan in the present.
