Tim's parents budget their household income carefully. They give 1/10 to the church, 2/5 of the total is used for their house payment, and 1/4 of the income is budgeted for groceries. What fraction of the total remains after they have paid their tithe, house payment, and grocery bill?

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

two? xd
