Layana’s house is located at (2 and two-thirds, 7 and one-third) on a map. The store where she works is located at (–1 and one-t

NeTakaya

We have been given that Layana’s house is located at $(2\frac{2}{3}, 7\frac{1}{3})$ on a map. The store where she works is located at $(-1\frac{1}{3}, 7\frac{1}{3})$ .

We are asked to find the distance from Layana’s home to the store

We will use distance formula to solve our given problem.

Let us convert our given coordinates in improper fractions.

$2\frac{2}{3}\Rightarrow \frac{8}{3}$

$7\frac{1}{3}\Rightarrow \frac{22}{3}$

$-1\frac{1}{3}\Rightarrow -\frac{4}{3}$

Now we will use distance formula to solve our given problem.

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Upon substituting coordinates of our given point in above formula, we will get:

$D=\sqrt{(\frac{22}{3}-\frac{22}{3})^2+(\frac{8}{3}-(-\frac{4}{3}))^2}$

$D=\sqrt{(0)^2+(\frac{8}{3}+\frac{4}{3})^2}$

$D=\sqrt{0+(\frac{8+4}{3})^2}$

$D=\sqrt{(\frac{12}{3})^2}$

$D=\sqrt{(4)^2}$

$D=4$

Therefore, the distance from Layana's home to the store is 4 units and option A is the correct choice.

Find the area of the composite figure.

irga5000 [103]

Answer:

Option C, 488 square centimeters

Step-by-step explanation:

<u>Step 1: Determine the area of the rectangle</u>

$A = l * w$

$A = 22\ cm * 17\ cm$

$A = 374\ cm^2$

<u>Step 2: Determine the area of the triangle</u>

$A=\frac{h*b}{2}$

$A=\frac{19\ cm * (22\ cm-10\ cm)}{2}$

$A=\frac{19\ cm * (12\ cm)}{2}$

$A=\frac{228\ cm^2}{2}$

$A=114\ cm^2$

<u>Step 3: Determine the total area</u>

$A_{total} = 374\ cm^2 + 114\ cm^2$

$A_{total} =488\ cm^2$

Answer: Option C, 488 square centimeters
