Based on the 100-year rainfall records at a certain location in a city, the rainfall intensities with an annual exceedance probability of 0.1 (10-year return period) of different duration are given below. Duration, td (min) 15 30 60 120 Intensity, i (mm/h) 161 132 103 74 a) Determine the coefficients a and c for the following intensity-duration-frequency (IDF) curve using the least-squares method: , in which i

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

answer: 177/8

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
