Answer: 32 paving stones

Step-by-step explanation:

Hi, to answer this question, first we have to convert the measures of the paving stones into meters.

Since: 1m = 100 cm

50 cm /100 = 0.5m

Now, we have to calculate the area of each paving stone:

Area of a square: s^2 = 0.5^2 = 0.25m2

Next, the area of the path.

Area of a rectangle = width x length = 1 x 8 = 8 m2

Finally, we have to divide the area of the path by the area of each paving stone:

8/0.25 = 32 paving stones

Feel free to ask for more if needed or if you did not understand something.

Answer: Jonathon needs to buy 32 paving stones.

Step-by-step explanation:

The paving stones are square and 50cm wide. Since each paving stone is a square, the side lengths are equal. Area of each stone is

50² = 2500 cm²

100 cm = 1 meter

the path is to be 8m long and 1 m wide. Converting to cm, it becomes

Length = 8 × 100 = 800 cm

1 × 100 = 100 cm

Area of the path to be covered is

800 × 100 = 80000 cm²

Therefore, the number of paving stones that Jonathon needs to buy is

80000/2500 = 32

Answer:

The slope for this equation is \frac{1}{7}.

Step-by-step explanation:

                       x         y

point 1:           -4        -3

point 2:           3        -2  

slope:             \frac{1}{7}

To solve for slope here is an equation, to help: \frac{y^2-y^1}{x^2-x^1}

\frac{y^2-y^1}{x^2-x^1} \\\\\frac{-2-(-3)}{3-(-4)} \\\\= \frac{1}{7} \\

A) x= all real #s<br>B) x&gt;0<br>C) x=5<br>D) x=12​
sashaice [31]

Answer:

Set of all real numbers

Step-by-step explanation:

When we talk of domain, we mean the possible values of x that the equation can take without being undefined

So x-values that makes the equation defined are the domain of the graph

From the diagram, we can see that the graph extends from negative infinity to positive infinity

What this mean is that the possible values here come from the top right and extends to the left

So this means that the range of possible values are the set of all real numbers
