Question 1 of 10

statuscvo [17]

Answer:

slope is -1

Step-by-step explanation:

Slope of the line is changes in y over changes in x. It can also be referred as rise over run.

We can express mathematically as:

$\displaystyle{m=\dfrac{y_2-y_1}{x_2-x_1}}$

where m is slope.

Let (-2,5) be $\displaystyle{(x_2,y_2)}$ and (6,-3) be $\displaystyle{(x_1,y_1)}$ . Hence, apply the slope formula:

$\displaystyle{m=\dfrac{5-(-3)}{-2-6}}\\\\\displaystyle{m=\dfrac{5+3}{-8}}\\\\\displaystyle{m=\dfrac{8}{-8}}\\\\\displaystyle{m=-1}$

Therefore, the slope is -1

Zoe is packaging a gift to send in the mail. A smaller gift box is placed inside a similar yet larger packaging box. The empty s

MrRissso [65]

Packing boxes are similar shapes with the coefficient of similarity k=2.1. The volumes of similar shapes are proportional with the coefficient

$K=k^3=2.1^3=9.261.$

Then

$\dfrac{V_{large}}{V_{small}}=K\Rightarrow V_{large}=9.261V_{small}=9.261\cdot 24=222.264\ cm^3.$

The volume of the tissue paper in the packaging box is

$V_{paper}=V_{large}-V_{small}=222.264-24=198.264\ cm^3.$

Answer: $198.264\ cm^3.$
