The number of hours required to do a painting job is represented by the function f (x) = 2/5 , where f(x) gives the number of hours and x is the number of painters doing the job. how much time will {4, 10, 14, 16, 18} workers take to do the job?

The average human heart beats 1.15 \cdot 10^51.15⋅10 5 1, point, 15, dot, 10, start superscript, 5, end superscript times per day. there are 3.65 \cdot 10^23.65⋅10 2 3, point, 65, dot, 10, start superscript, 2, end superscript days in one year.how many times does the heart beat in one year? write your answer in scientific notation, and round to one decimal place.

What is the equation of a line passing through the point (6,1) and parallel to the line whose equation 3x=2y+4

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
