Question

Середня маса 6 яблук у кошику дорівнювала 155г. Мама поклала до 7 яблуко . Після цього середн я маса яблук укошику склала 160г. Якою є маса 7 яблука?

Answer 1

155 * 6 = 930 г - масса 6 яблок

160 * 7 = 1120 г - масса 7 яблок

1120 - 930 = 190 г - масса седьмого яблока

Answer 2

Calculation of the Weight of 7 Apples

To calculate the weight of 7 apples, we can use the given information about the average weight of 6 apples and the resulting average weight after adding the 7th apple.

Let's break down the information provided:

- The average weight of 6 apples in the basket was 155g. - After adding the 7th apple, the average weight of the apples in the basket became 160g.

To find the weight of the 7th apple, we can set up the following equation:

(6 * 155g + x) / 7 = 160g

Where 'x' represents the weight of the 7th apple.

To solve for 'x', we can rearrange the equation:

6 * 155g + x = 7 * 160g

Now, let's calculate the weight of the 7th apple using the equation:

6 * 155g + x = 7 * 160g

(6 * 155g) + x = 7 * 160g

930g + x = 1120g

Subtracting 930g from both sides:

x = 1120g - 930g

x = 190g

Therefore, the weight of the 7th apple is 190g.

Please note that this calculation assumes that all the apples have the same weight.
