ann is grouping 38 rocks, she can put into groups of 10 rocks or as single rocks what are the different ways she can group them
inysia [295]
Since Anna is either grouping them as single rock or as group of 10, we need to find the maximum number of groups of 10 as follows: 38/10 = 3.8

This means that Anna can make maximum 3 groups of 10 rocks.

Based on this, the different ways to group the rocks are as follows:
- 3 groups of 10 and 8 (which are calculated as: 38-30) single rocks
- 2 groups of 10 and 18 (which are calculated as: 38-20) single rocks
- 1 group of 10 and 28 (which are calculated as: 38-10) single rocks
- 0 group of 10 and 38 (which are calculated as: 38-0) single rocks

Find the slope of the line through points (4, 6) and (-6,2).
Pie

Answer: Slope = 2/5

Concept:

Here, we need to know how to find the slope.

Slope = (y₂ - y₁) / (x₂ - x₁)

If you are still confused, please refer to the attachment below for a clearer version of the formula

Solve:

<u>Given information</u>

(x₁, y₁) = (-6, 2)

(x₂, y₂) = (4, 6)

<u>Given formula</u>

Slope = (y₂ - y₁) / (x₂ - x₁)

<u>Substitute values into the formula</u>

Slope = (6 - 2) / (4 - (-6))

<u>Simplify values in the parentheses</u>

<u>REMEMBER to change [+, -] signs when there is a [-] sign in front</u>

Slope = 4 / (4 + 6)

Slope = 4 / 10

<u>Divide both numerator and denominator by 2 to get the simplest form</u>

Slope = (4 ÷ 2) / (10 ÷ 2)

Slope = 2/5

Hope this helps!! :)
