To take sweepstakes for the largest pumpkin crop at the riverside county fair the average weight of ethan's to pumpkins must be greater than 875 lb one of his pumpkins is 903 lb what is the least amount of pounds ii pumpkin could weigh in order for ethan to win the prize

Step-by-step explanation:

Let be the weight of the second pumpkin.

Given that weight of first pumpkin is pounds.

Since we need the weight of the second pumpkin to be minimum,the average weight of the two pumpkins must be just equal to the required weight to win.

Given that the required weight to win is pounds.

So,

pounds

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
