Acontractor digs a hole that is 40 ft long and 10.5 feet deep. what is the width of the hole if 6,510 cubic feet of dirt is removed?

the width is 15.5

Step-by-step explanation:

6,510 = 40 x 10.5 x W

6,510 ÷ 420 =  420w ÷ 420

      W = 15.5

step-by-step explanation:

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.
