Question

Белка на зиму запасла еловые шишки, сосновые шишки и орехи. Еловых шишек она запасла m(неизвестное кол-во) штук, сосновых- на 40 больше, а орехов -в два раза больше, чем всех шишек. Верно ли утверждение? а)Если сосновых шишек запасено 100 штук, то m(неиз. кол-во)=60 б)Всего белка запасла 4m+40 ореховПожалуйста помогите!!!

Answer 1

А) Еловых m = сосновых - 40 = 100 - 40 = 60 - Верно.
б) Шишек - m + m + 40 = 2m + 40. Орехов 2*(2m + 40) = 4m + 80
4m + 40 - Неверно

Answer 2

Problem Analysis

The problem describes a scenario where a squirrel has stored pine cones, fir cones, and nuts for the winter. It provides information about the quantities of each type of item stored and presents two statements to be verified.

Given Information

- Quantity of fir cones stored: m (unknown quantity) - Quantity of pine cones stored: m + 40 - Quantity of nuts stored: 2(m + m + 40)

Verification of Statements

a) If 100 pine cones are stored, then m (the quantity of fir cones) is 60. b) The squirrel stored a total of 4m + 40 nuts.

Verification Process

a) If 100 pine cones are stored, then the quantity of fir cones is 60: - Given: Quantity of pine cones = m + 40 - If 100 pine cones are stored, then m + 40 = 100 - Solving for m: m = 100 - 40 = 60 - Therefore, the statement is true.

b) The squirrel stored a total of 4m + 40 nuts: - Given: Quantity of nuts = 2(m + m + 40) - Substituting the value of m from part a: 2(60 + 60 + 40) = 2(160) = 320 - Therefore, the statement is false.

Conclusion

a) The statement "If 100 pine cones are stored, then m (the quantity of fir cones) is 60" is true. b) The statement "The squirrel stored a total of 4m + 40 nuts" is false.
