Question

ПОМОГИТЕ СРОЧНО! На трёх участках растёт 282 куста смородины. Количество кустов, растущих на первом участке, и количество кустов, растущих на втором, составляют 11/15 и 140% количества кустов, растущих на третьем участке. Сколько кустов растёт на третьем участке?

Answer 1

x=282/(11/15+14/10+1)=90 кустов

На третьем участке растёт 90 кустов.

Answer 2

Calculation of the Number of Currant Bushes on the Third Plot

To find the number of currant bushes on the third plot, we need to analyze the information provided. Let's break it down step by step:

1. The total number of currant bushes on the three plots is 282. 2. The number of bushes on the first plot and the number of bushes on the second plot together make up 11/15 of the total number of bushes. 3. The number of bushes on the second plot is 140% of the number of bushes on the third plot.

Let's assign variables to the unknown quantities: - Let x be the number of bushes on the first plot. - Let y be the number of bushes on the second plot. - Let z be the number of bushes on the third plot.

Based on the given information, we can set up the following equations:

Equation 1: x + y + z = 282 (the total number of bushes on the three plots) Equation 2: x + y = (11/15) * 282 (the number of bushes on the first and second plots combined is 11/15 of the total) Equation 3: y = 1.4z (the number of bushes on the second plot is 140% of the number on the third plot)

To solve this system of equations, we can use substitution or elimination. Let's use substitution:

From Equation 3, we can express y in terms of z: y = 1.4z.

Substituting this into Equation 2, we get: x + 1.4z = (11/15) * 282.

Now we have two equations with two variables: Equation 1: x + y + z = 282 Equation 4: x + 1.4z = (11/15) * 282

Let's solve this system of equations to find the values of x and z.

Subtracting Equation 4 from Equation 1, we get: (1 - 1.4)z = 282 - (11/15) * 282.

Simplifying: -0.4z = 282 - (11/15) * 282.

Now we can solve for z: z = (282 - (11/15) * 282) / -0.4.

Calculating this expression, we find that z ≈ 90. Therefore, there are approximately 90 currant bushes growing on the third plot.

Please note that the calculations are based on the given information and the assumptions made.
