20 pupils can plant 1000 eucalyptus trees in 4hours . Home many trees can 30 pupils plant in 6 hours

2250 trees

Step-by-step explanation:

Find how many eucalyptus trees are planted in an hour.

4 hours = 1000

1 hour = 1000 ÷ 4 = 250

20 pupils = 250

1 pupil = 250 ÷ 20 = 12.5 (in an hour)

30 pupils = 12.5 x 30 = 375 trees (in an hour)

6 hours = 375 x 6 = 2250 trees

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
