You earn $15 an hour mowing lawns and $10 an hour washing windows. You want to make $400 in one week. An algebraic model for your earnings
is 15x + 10y = 400, where x is the number of hours mowing lawns and
y is the number of hours washing windows.
37. What are your earnings for 3 hours of mowing and 5 hours of 952
window washing?

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:

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465
