Graham is hiking at an altitude of 14,040 feet and is descending 50 feet each minute. max is hiking at an altitude of 12,500 feet and is ascending 20 feet each minute . how many minutes will it take graham and max to meet at the same altitude

The answer to your question is: 51.33 min

Step-by-step explanation:

Data

                         Graham                        Max

height              14040 ft                       12500 ft       difference  = 1540 ft

speed               50 ft/min                     20 ft/ min

Formula

                 v = d/t   clear d from this equation d = vt

Equation

                    Graham             Max

                       50t        =     1540 + 20t

Solve it          50t - 20t = 1540

                     30t = 1540

                     t = 1540 / 30

                     t = 51.33 min

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
