BRAINLIESTTT ASAP! PLEASE HELP ME :)

Explanation:

Multiply the values in the second and third columns. Do this row by row.

Row1: 50*55 = 2750

Row2: 75*32 = 2400

Row3: 150*13 = 1950

Add up the products to get 2750+2400+1950 = 7100

Then divide this by the total frequency 55+32+13 = 100 to get 7100/100 = 71

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.

5.762159

step-by-step explanation:

it would be 9 because when it is the nine is over five so that would mean it rounds up to 90 or 9
