Joe black receives a salary of 2240 per month if 18% is deducted for income tax and 6% is deducted for saving how much does joe take home

$1726.59

Step-by-step explanation:

Long form:

$2240×18%=(-$403.20)

$2240-$403.20= $1836.80

Taxes will be deducted from total gross pay first...

$1836.80×6%=(-$110.21)

$1836.80-110.21=$1726.59

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

step-by-step explanation:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
